PERMISSIBLE CIRCUIT LENGTHS CALCULATION OF VOLTAGE DROP
USE OF TABLE AND GRAPHS
Example 1--To find permissible circuit length for a 4 AWG lighting feeder, 3 wire single phase, to carry 100 am peres at 30C ambient and not to exceed 1 percent voltage drop: 120 volts x 1% = 1.2 volts, permissible drop. Refer to graph for 30C ambient. Find the intersection of 100 amperes and ^4 AWG. From this point move horizontally to the left and read a drop of 3.15 volts for 100 feet of conductor. 1 2 x 100 = 38 feet permissible circuit length.
Example 2--For the same circuit length, voltage and load as in Example 1 find the required conductor size for 50C am bient: From the graph on page 77 for 50C ambient note that 43 AWG is the smallest cable that can carry 100 am peres at 50C. From the intersection of 100 amperes and # 3 AWG move horizontally to the left. The voltage drop for this combination of load and conductor size is 2.70 volts per
100 feet
x 100 = 44 feet. Therefore, #3 AWG is
2.70
^
satisfactory for this requirement
FOR OTHER THAN RATED LOADS
The table on page 76 shows permissible circuit lengths for rated load only. An approximation may be made for other currents by multiplying by the ratio of the currents. For more accurate results the graph should be used.
FOR OTHER THAN 100% POWER FACTOR
Table--page 76--Divide the circuit length from the table by the factor given in the POWER FACTOR CORREC TION TABLE tot 110C. Conductor temperature tor the desired power factor.
Graphs--Locate the intersection of load amperes and con ductor size. Note approximate conductor cempetitute. At the left read volts drop. Multiply the volts drop by the POWER FACTOR CORRECTION factor for the indicated conductor temperature. Where necessary interpolate the factor between temperatures listed or use factor tot next lower temperature below that read from graph.
Example 3--To find proper conductor size for 323 foot
power circuit 440 volt 3 phase, 325 amperes, 80% power
factor, JC"C ambient, voltage drop not to exceed 3%: Per
missible voltage drop is 440 x .0*3 = 13.2 volts phase to
phase. From graph for 30C ambient note that 300-MCM
is smallest conductor that can carry 325 amperes. From in
tersection of 325 amperes and 300 MCM read 1.6a volts
drop pet 100 feet of conductor at 100% power factor. Con
ductor will be operating at approximately 95G From the
POWER FACTOR CORRECTION TABLE for 80% power
factor, interpolate the factor for 95C = 1.41. The voltage
drop at 80% power factor would be: 1.62 x 1.41 x 3-25
(number of hundred feet of circuit) x 1.73 (since this is a
3 phase circuit) = 12.84 volts. This is less than the 13.2
volts drop phase to phase permitted; therefore, 300 MCM
meets the requirements of the circuit.

TERMINAL and JOINT INSULATION FOR A.V.C. CABLE
In general, no special precautions ate necessary in the insulating and waterproofing of terminals or joints in A,V C. cable runs. This is because or the additional ther mal capacity of thermal ends and ioincs. pics the fact that in general such terminal ends o: joints are in cooler ambient locations than the main run of the cable. In this type or location it is common practice to use rubber tape and friction tape as a means of insulation. For large sizes of A.V.C cable where a splice is neces sary, it is advisable to build up the joint with layers of varnished cambric tapes prior to the application of the robber and friction tapes, !n wet locations where lead covered A.V.C. cable is used, the same practice is used except that the triction tape is
treated with a giyptal varnish or Irvington oil stop. The illustration below shows a recommendation for such a cable splice.
In ail high voltage, i.e. over bOO volts, all termm.a! ends and joints should be insulated with varnished cam.ctu tape before ippiying the rubber or friction tapes. The friction tape should be treated with either giyptai varnish or Irvington oil stop. Where it is necessary either to terminate or make a joint in a high ambient temperature zone, we recommend that the joint or terminal end be insulated with layers of var nished cambric tapes wrapped with asbestos listing. List ing can be coated with wax or covered overall with friction rape.
^*
1%
SUGGESTED METHOD OF SPLICING AVA OR AVL CABLE

Here is a special lead sheathed heating cable designed to solve a problem in the manufacture of refrigeration units. The problem was to speed the time requited in the deicing cycle without appreciable temperature rise in the cold cham ber. The answer here was to design a heating cable suitable for higher voltage operation than our Table LH industrial heating cable shown on page 61. This heating cable con struction has successfully solved this problem. It is suitable for 440 volt service and has a maximum sheath tempera ture of 350F.
Along with the trend toward outdoor power plants came the need for protecting high temperature steam and p lines from freezing during shutdown periods. Rockbei... Field Engineers called in to study this problem designed this special construction to be applied between the layers of pipe insulation. This provided an ideal solution as the sili cone treated insulation and silicone treated glass braid con struction withstood the high temperatures developed during the normal operation of steam lines and when steam lines were not operating provided a heat source of sufficient temperature to keep the condensate from freezing. This heating cable is rated at 440 volts and has maxi mum operating temperature of 500F.
Rockbestos Heating Cable Designs can be developed to solve your electrical heating problems--furnish complete data cov ering temperature desired, heat dissipation, etc. with your inquiry.

conform to irregular shaped objects. It is best used wrapped around pipes and cov. ered with a good standard pipe insulation for greatest economy. We can only touch on a few typical applications to which our customers have put this heating cable, but they will give you a good idea of the varied uses to which it has been put.
In many plants the cable is used as a safeguard against frozen water pipes miking unnecessary the rearrangement of piping or costly replacement. Waste pipes, eaves troughs and down spouts can also be kept free and dear of ice.
Paint, soap, varnish, ink, chocolate, molasses and sulphur, to name a few. can be kept at fluid temperatures insuring against irregular flow and dogged conveyor pipes.
Wet pipe sprinkler systems located in unheated areas are easily heated and kept at non-freezing temperatures that assure positive operation.
Med miils use it around roiLnecks to prevent the lubricant from congealing and a utilities engineer wound the cable around the pipes connecting the conservator tank to the main tank of a conservator type transformer, covered it with lagging, and eliminated congealing of oil and freezing of condensate.
The resistance of Rockbestos Industrial Heating Cable is approximately 0.5 ohms per foot. In order to keep the temperature low enough so that the insulation will not be injured, the generally recommended length across 115 volts, is <$0 feet. The recommended wattage limit is 7 watts per foot. At 110 volts a <50 ft. length is rated at 400 watts, 6.66 watts per ft. Across 220 volts use a 120 ft. length for the same current value and double the total wattage. Caution: Do not use Table LH where maximum voltage exceeds 120 volts to ground. Table LHV is suitable for 440 volt service in 240 foot lengths and is U.L. approved by report for pipe heating applications.
When installed permanently, Rockbestos Industrial Heating Cable should be cov ered by some form of heat insulating material for operating economy.
Precise temperature control is established by means of a low priced thermostat available from a number of manufacturers. We will be glad to refer you to several. The characteristics of this particular heating cable are given simply because it is a standard product and usually available from stock. We are equipped, however, to

ROCKBESTOS FIREPROOF LOW VOLTAGE

3. SYNTHETIC TAEE
i. ASaESTes 38*0
Rockbestos low voltage vault cable was designed to provide a heatproof, fireproof and molstureproof cable for bus instal lation in underground vaults of low voltage distribution sys tems, The typical installation is between transformers and network protectors, mounted on porcelain insulators without phase to phase or phase to ground contact. The special insulation on Rockbestos Vault Cable is like the insulation in Rockbestos Secondary Network Cable--impreg nated pure asbestos which is unaffected by heat or age and positively will not burn. In addition, to seal the insulation
against the moisture so often encountered in underground vaults, a thin layer of waterproof synthetic tape material is applied over the asbestos insulation, under the asbestos braid. With, extreme overheating or actual fault conditions the only smoke oc gas generated is from the decomposition of the synthetic waterproof tape layer, and is of such small quantity, due to the thin, layer, that it is negligible and does nor inter fere with prompt access to the vault for service rescoratic Supplied with standard concentric stranding or segment, conductor.

Ruckbescos Low Voltage A.C. Secondary Network Cabie was developed exclusively for secondary network distribution systems but several utility companies have extended its use, where regulations permit, to include service installations in which limited space, high ambient temperature and emer gency overloads must be considered.
Under the worst fault conditions, whether single, two, or three-phase, loose or solid, Rockbestos A.C. Secondary Net * work Cable will dear cleanly and quickly without burning ' or generating toxic inflammable or explosive gases. It also definitely eliminates the smoke nuisance because neither the insulation, which is pure asbestos, nor the impregnating com pounds will burn.
Another advantage is positive resistance to deterioration nor mally resulting from age or heat. Under overloads when the cables become warm, there need be no fear of failure as the insulation will remain intact up to the melting point of cop per. However, the melting point of solder joints, if used, and the copper temperature at which regulation difficulties would be experienced, determine the load the cable can carry. A temperature of 150C has been set as the recommended maximum coppet temperature for extended periods, although in emergency conditions much higher temperatures will not endanger the cable.

Rockbestos manufactures Pyrometer and Thermocouple wire with two types of insulation--Rockbestos A.V.C. and All Asbestos. If preferred, either construction may be had with lacquered cotton or glass braid instead of asbestos braid. These Rockbestos Pyrometer and Thermocouple wires are not only heat and moisture resisting, but fireproof as well. They will not grow hard or brittle, or crack under temperatures that would be destructive to other types of insulation. Neither will they rot or bloom even if exposed constantly to oil, oil fumes or grease. If fires involve the circuits, there will be no plugging of conduit, and in many cases the wire will con tinue to operate properly. These qualities are inherent because the insulation is made from asbestos, the basic heat-resisting and fireproof material. For short conduit runs subjected only to heat, oil or fumes, the All-Asbestos insulation will be satisfactory. If the con duit run is likely to be subjected to condensation or when ever this condition is doubtful, we recommend the A.V.C insulation. We can supply All-Asbestos or A.V.C. insulated single con
ductor pyrometer and thermocouple wire with solid or stranded iron, or solid or stranded copper conductors, T insulations are also applied to conductors furnished by .... customer. *See special note.
We also offer the parallel construction illustrated above. Duplex construction can be furnished if both conductors are stranded. Both are covered with an asbestos braid, and polar ity identification can be supplied by means of either colored asbestos insulation or a marker thread.
There are so many combinations of solid or stranded conduc tors and dissimilar metals that it is impossible to tabulate them, but we will quote prices on any combination on re quest. Let us know size, whether solid or stranded, enameled or plain copper, what combination of copper, iron or aiioy conductors you are using, and whether you want to use two single conductors or to combine both under one braid, and we will draw up specifications and quote.
`Note: When specifications call for an alloy conductor, it must be furnished by the customer as we cannot accept the responsibility of supplying alloy conductor having the proper thermoelectric charac teristics.

The wiring of the control systems of early automatic coal and oil burning installations formerly gave frequent trouble. To get short runs it was often installed dose to, or actually resting on, hot water or steam pipes and the heat naturally deteriorated ordinary insuJaced wire to the point where trou ble frequently occurred. Cases are on record where serious damage has resulted from faulty control wiring.
Abrasion, too, has always been a source of trouble when fish ing ordinary control wire, particularly in buildings already up. Sharp corners, brickwork, plaster, protruding nails and tough beams all tend to damage the insulation.
With these conditions in mind, and with the wide adoption of automatic fuel burning systems, a large manufacturer of heat control apparatus asked us to design a wire which would be heatproof and abrasion resisting--and Rockbestos Ther mostat Control Wire was the result.
Rockbestos Thermostat Control Wire is very strong mechan ically because of its firm felted asbestos insulation and its rugged, abrasion resisting spiral steel armor or metal braid.
It is heatproof and will not dry out under heat or with age. It eliminates fire hazard because it cannot burn. Neither can rats damage it as has been known to happen occasionally with unprotected wires. Where resistance to abrasion or protection against rodents is not essential, a cotton braid may be speci fied instead of metallic sheath. With these advantages it is of value for control and intercommunicating systems or tor any similar application where a low voltage, multi-conductor cable is required.
Rockbestos Thermostat Control Wire is designed to be used at low voltages, usually fed by a step-down transformer. For this application the 12^4 mil wall insulation is generally used. However, some users prefer the 25 mil insulation thick ness for its added mechanical and dielectric strength. Where this cable is to be used direct on 115 volt circuits a minimum insulation thickness of 31 mils is recommended. Data for cables with all three insulations is listed in the table below.
Nora: The metal braid covering mentioned in the fourth paragraph is an optional suggestion.

CONSTRUCTIONAL FEATURES
Rockbestos PNR was designed and developed in dose coop
eration with a power company who had the problem of
z:::r.ir.g
: 71. >
called for a small diameter, light, tough, flexible tooctoi table
to operate at a temperature of 75C
Rockbestos Engineers provided the answer to this problem by designing an electrical insulation wnich combined Poly ethylene, Nylon and Rockhide, (Polyvinylchloride). Because of the excellent properties of these thermoplastics , the appli cation for this new construction was extended to control cir cuits exnpsed to weather and to installations requiting direct burial.
Polyethylene was used because of its excellent dielectric prop erties, resistance to water and moisture, and flexibility at low temperatures. Nylon, extruded over the Polyethylene on the individual conductors provided exceptional resistance to abra sion, oils, gasolines and high temperatures. These individual conductors were cabled together as a concentric cable with lateral fillers added where necessary and the completed cote wrapped with a sheath tape. A tough outer covering of Rockhide (Polyvinylchloride) was used to jacket the individual conductors because of its extreme chemical inertness. It is unaffected by alkalies, weather and sunlight.
This original Rockbestos PNR construction, since its incep
tion in L948, has been service proved through the successful
operation of millions of feet of this cable by utilities and
industrial plants.

Advantages in Using Rockbestos PNR:
Small in diameter Smaller conduit required--You can put twelve conductor cable in conduit where you now use six or seven, or you can use smaller conduit and fittings to save on steel and installa tion costs.
High dielectric strength--Dielectric breakdown . . . over 40 times operating voltage.
Excellent moisture resistant--Withstands attacks of chem icals. add or alkaline soils, oil, grease, gasoline and alcohol.
Abrasion resistant--The tough Rockhide sheathed rcr.:-cable can be buried directly in the ground.
Good low temperature flexibility--Flexible to (Minus 67C'F) no cracking
Non-restricted Multi-Control Came Appiw.mh"'-- In conduit Direct Burial Exposed Overhead
Total =A small, light, tough, flexible control cable to give long life at low cost.
SPECIFICATIONS
Construction Individual Conductors: Stranded copper 4:9 AWG 19 " *12 AWG 19/25, and #14 AWG 19/27. PNR Control Cables can be supplied in other sizes inducing #16 and #18 with any number of conductors and with heavier wall thicknesses where required. Single conductors are not recommended for Direct Burial or exposed overhead applications without Rockhide Sheath covering.
Primary Insulation: ZOl/j mils (161/, mils of extruded heat and light stabilized Polyethylene and 4 mils of extruded Nylon over the Polyethylene).
Cabling: Individual conductors are cabled together as a con centric cable with non-wicking jute laterals where required, The complete core is wrapped with a sheath tape. The stan dard make-up on two conductor construction is to cable the conductors with fillers to make round.
Jacket: Extruded Rockhide.
Color Code Coded to NEMA Standard Color Code for Multi-Conductor Control Cables, (Sec page 20) or can be supplied with simplified color code using all conductors black except one conductor white in each layer.

ai.<4uc'.o> Hi Resisting flexible Coras are apyro'-;-.! ot rise Underwriters' Laboratories for lighting fixture wiring under the type symbols shown above the illustrations. In lamp sockets the usual temperature rise is from 50 to 2003C above ambient depending upon the lamp wattage, type of shade and other factors. Experience has shown that with rubber fixture cord in use, the insulation of the wires in and immediately above the socket dries up and becomes brit tle until finally, with the repeated movement of the pendant, due to operation of the chain pull socket or from vibration, the insulition just above the socket cracks and crumbles, per mitting the w-ires to short circuit. In consideration of this condition, therefore, it is especially important to use genuinely heat-resisting cord whose insula tion will not dry up and thus crack and eventually cause short circuits. Rockbestos Duplex ot Twisted Pair Cord is ideal for this purpose. The Twisted Pair and Triplex Cords have similar uses to the Duplex. The Triplex is for lighting fixtures having pend-

(viXMJCAius AII-Aiuestus Curd was original a- rwnrf-1 in' cab and gauge lighting circuits of sceam locomotives to re place rubber insulated cords which failed to stand up under heat and vibration. Because of this use it is widely known in the railroad field as Cab Cord.
There is no rubber whatever in this construction. Instead the basis of the insulation is asbestos, applied to the wire by our unique insulating process and impregnated and compressed to rorm [fie felted asbestos wall. It meets a demand for a heat-resisting, fireproof, permanently flexible cord which will operate without failure under exposure to heat, corrosive fumes, oil, grease or fire hazard.
Because it will not dry up and crack under heat, it makes an idea! heavy duty cord for pendant lighting fixtures located in high temperature areas in steel mills, boiler rooms, kilns, glass plants, etc. It is also used for leads in heat-developing
jnotrirus and for rhe wiring of oiitepnnc m.irn,rve. and spot lights and other high wattage units which develop temperatures that are ruinous to other types of insulated wires. For applications in which moisture may be encount ered, use Rockbestos A.V.C. Flexible Coed described on page 19. If a perfectly round construction is desired it can be made up with fillers on special order.
If required for AFPD applications it can be made with polarized conductors on special order.
Standard finish colors: Black and white. Authorized stock items: Black.
RAILROADS NOTE: For lighting circuits in locomotives equipped with train control apparatus we recommend using Rockbestos A.V.C. Flexible Cord because of its higher insula tion resistance.

Aj!;cc:cc :hsc:r?t wir* was originally DroJiiLeiJ bv outiins two oc three braids or asbestos yarn on the wire and flniildi'.g each braid with compound. This had several disadvantages. For example, its moisture resistance was very low due to the comparatively open covering so that many engineers consid ered that spaced wiring was necessary in order to prevent possible leakage under damp conditions. The labor cost of doing this type of wiring is high.
Another disadvantage--though really more of an annoyance --was that in working with this wire a good deal of the compound flaked off and continued to do so after the instal lation was completed, spoiling the appearance of an other wise nice job.
The Rockbestos development of the felted and impregnated wall of asbestos insulation was a distinct improvement. In stead of a relatively open covering on the wire, the asbestos is applied in the form of a homogeneous insulation. The dielectric strength is thereby increased. Next, the impregnat ing compound is an integral part of the insulating wall, not
printed or. after the wail Is formed. That means that, through repeated neat'Pg md rooiing cycles, die compound car. r.:":; fail away from the asbestos. The dielectric strength and mois ture resistance of Rockbestos Rheostat Wire are, therefore, practically constant. And there is none of the usual flaking when working with Rockbestos Rheostat Wire and Cable, with either white or black braid.
Because of its comparatively high moisture resistance Rock bestos Rheostat Wire may be bunch-wired with safety, and it is also recommended for open wiring carrying less than 600 volts which is subject to high temperatures or rotting, corrosive fumes. For a 300 volt construction of the same type refer to page 44.
This wire is National Electrical Code Type AIA listed by the Underwriters' Laboratories as Type AIA wire and has a maximum operating temperature 125C (257F).

Page 50 in this section lists both plain and braided fix ture wires foe 300 volt serv ice. In fixtures where the
wiring is concealed in stems or brackets, the PLAIN type is
recommended. It has no braid. Made in black and white to
indicate polarity.
When wiring is exposed, such as on chain pendant fixtures,
the BRAIDED wire is recommended. Made in solid color
braids and solid color with market thread to indicate polarity.
Rockbestos Heat Resisting Fixture Wires are approved by the Underwriters' Laboratories for lighting fixtures and beat their labels. The impregnated asbestos insulation withstands the high socket temperatures developed by high wattage or flush type fixtures without drying out ot becoming hard ot brittle. This type of insulation also eliminates fite hazard as it is resistant to flame as well as heat. Furthermore, it is moisture resisting, an important factor where fixtures hang in damp ot humid locations.

The flexible cords on page 5 L ace approved by Underwriters' Laboratories for lighting flxture wiring under the tvpe svmbuls shown.
The 300 volt All-asbestos Flexible Cords shown on page 49 were originally developed for cab and gauge lighting circuits of steam locomotives to replace rubber insulated cords which failed to stand up under exposure to heat and vibration. Its heavy duty asbestos braid construction made it ideal for pendant lighting fixtures located in high temperature loca tions in steel mills, boiler rooms, kilns and glass plants requiring a heavy duty flexible cord which would operate without failure under exposure to heat, corrosive fumes, oil. grease, and fire hazard-

This wire was designed for railway locomotive applications in which a singLe conductor wire is mote convenient to use than A.V.C, Flexible Cords (Cab Cords).
The construction illustrated above has the same characteris tics that are to be found in other A.V.C. wires, cables and cords--high dielectric strength and resistance to heat and moisture.
Standard finish colors: Black and gray. Be sure to specify braid color desired on order.
This wire can be finished in grey to match the appearance of out standard switchboard wires Listed in this section. Its flexi ble conductor offers an intermediate stranding between Table 5S and Table BH for Switchboard Applications. This con struction also lends itself to many applications in which stranded conductors are not only preferred but are an essen tial requirement because of their greater flexibility.
This Rockbestos A.V.C. 600 volt Headlight wire is desig nated as National Electrical Code Type AVB and has a maxi mum operating temperature of 90C (194F).

The general use of Rockbestos A.V.C. Switchboard Wire and Hinge Cable by switchboard builders, power companies, industrial plants, etc. brought forth requests for a cable with the same characteristics and finish for bus circuits. For this application we designed the cable illustrated above, similar in mnsrmfT'nr* tn o'lt A.V.C. Power Cable but coveted with a cotton braid instead of asbestos yarn.
This cable may also be used for conduit installations where Rockbestos A.V.C. Power Cable diameters tun too large, it is Mational Electrical Code Type AVB, has a maximum oper ating temperature of 90C (194F), is listed by Underwritets' Laboratories, and complies with NEMA Standards

SPECIAL CONSTRUCTIONS FOR ROCKBESTOS POWER AND CONTROL CABLES
This Rockbestos A.V.C. Control Cable illustrated is one of the many mukicondtictor cables designed to meet specific retirements in control and power circuits. They ire miJe up is shown or with either !eid sheath or armor only as specified and in ratings ranging from 600 to 5000 volts. (Synthetic sheath ings may also be specified for control cables where temperatures permit.) This type of cable not only protects operation of circuits exposed ro heat and moisture and other severe operating conditions, but also increases the flexi bility of wiring systems and makes circuits more easily accessible.
The felted asbestos insulation, impregnated with neat, dime md moisture resisting compounds, -withstands high temperatures, corrosive fumes, aging and conductor-heating overloads. The lead sheath protects it from excessive condensation resulting from heating and cooling cycles and complete sub mersion. The spiral bronze armor eliminates the need for conduit, an impor tant consideration in capacity expansion programs, as the cable can be run in troughs, up vertical risers ot over and around obstructions. Its flame and heat resistant structure will also maintain vital alarm and control system cir cuits for longer periods under exposure to flame than other conventional types.
The cable illustrated on this page is a special construction which is typical of many "specials" designed by Rockbestos to meet severe or unusual operating conditions.
Its construction consists of: Conduit saving bronze armor covering for protection against abrasion. Impregnated jute serve to cushion the armor and to protect the lead sheath from mechanical damage.
Lead sheathing for protection against immersion or excessive condensation. Friction tape to bind the cabled conductors securely together to maintain the lay-
individual conductors
Coded individual cotton braided conductors for easy circuit identification. Felted asbestos beneath the cotton braid impregnated with heat, flame and moisture resistant compounds.
Varnished cambric for high dielectric strength and added moisture resistance. Inner wail of felted asbestos to complete the A.V.C. construction serving as a baffle between the varnished cambric and heated conductors.

or complete submersion. You or. safely use
_p.cj
where a conduit run is exposed to widely varying condi
tions throughout its length, particularly in power stations
located on tidewater where certain ducts are sometimes
flooded but where another part of the same circuit is ex
posed to high temperatures,
Rockbestos Hi-I A.V.C. Multi-conductor power cables (Type AVL) consist of single conductor AV'A cables of the required voltage rating but without individual braids, cabled together with suitable lay and with impregnated jute fillers to maintain circularity of cross section. The assembled conductors are wrapped with a cable tape over which a lead sheath is applied.
These three conductor lead sheath cables are manufactured to NEMA Standards.
SPECIFICATIONS
Construction Stranded Dlain copper conductor
A Varnished cambric 4. Felted asbestos 5. Jute fillers 6. Cable cape

APPLICATIONS
SPECIFICATIONS
These Rockbestos Lead Sheathed Power Cables are used for Power and Lighting Circuits exposed to high temperatures in combination with excessive condensation or complete submersion.
Use this cable where a conduit run is exposed to widely vary ing condition: throughout k' length, pTT''~,drtrlv in rower stations located on tidewater where certain ducts are some times flooded but where another section of the same circuit is exposed to high temperatures. Also around ash pits where the wetting down of the ashes results in abnormal conden sation.
The Cables listed in this section all conform to NEMA Standards for Asbestos Varnished Cambric wires and cables with lead sheath.
The lead sheath has no effect on the ability of these cables to withstand high temperatures but affords protection against abnormal condensation or complete submersion.
Construction
1. Stranded plain copper conductor 2. Felted Asbestos 3. Varnished cambric 4. Felted asbestos s Lead sheath
13.:: c:n:e is Optional Eiectricai Code Type AVL, listed by the Underwriters' Laboratories and is available in sizes up to 2,000,000 CM. Maximum operating temperatures are as follows:
600 Volt 110 C (230F) 1000 Volt 110C (230F) 2000 Volt 109C (228F) 3000 Volt 106C (222F) 4000 Volt 103C (217F) 5000 Volt 100C (212F)
These cables are our Standard Power Cable constructions with a lead sheath, instead of an asbestos btaid.

POWER CABLE
TYPE AVA--ROCKBESTOS A.V.C.
APPLICATIONS
The three conductor Power Cables iisted in dus section are used for power circuits exposed to heat and moisture, corrosive fumes and fire hazard around boilers, furnaces, steam lines, in power plants, etc. These cables are recom mended for open wiring applications or for conduit runs. Rockbestos Three Conductor Power Cables have the same heat and moisture resisting qualities as single conductor constructions. Rockbestos Hi-I A.V.C, Multi-Conductor Power Cables (Type AVA) consist of single conductor AVA cables of the required voltage ratings but without individual braids, cabled together with suitable lay and with impregnated jute fillers to maintain circularity of cross section. The assembled conductors are wrapped with a cable tape over which is applied heavy asbestos braid. Lead sheath, armor, or lead sheath and armor can be furnished instead of as bestos braid on special order. These three conductor power cables are manufactured to NEMA Standards.
SPECIFICATIONS
Construction 1. Stranded plain copper conductor 2. Felted asbestos 3. Varnished cambric 4. Felted asbestos 5. Jute fillers 6. Cable tape 7. Asbestos braid
This construction consists of three individual power cables minus their outer braids, cabled together with jute fillers, taped and covered with a heavy asbestos braid.
Asbestos fillers may be substituted for jute if required.

APPLICATIONS
Modified in design from our Soaking Pit Cable for cover door control wiring wtych must 'vitbsmod the intense beat ot red-hot ingots when adjacent covers are off, this A. V, C control cable has proven resistance to high temperatures. This cable finds its use in steel mills, power stations, boiler rooms, automotive, ceramic and glass plants or other indus tries in which control and signal circuits ot control appara tus are exposed to heat or fire hazard. It is especially recom mended for use in circuits and apparatus in metal making mills, boiler rooms, and power plants as it is highly resistant

This cable is NEMA TYPE AVA with a maximum operat
ing temperature of 110C (230F).
Conductors The standard standings furnished on these Rockbestos A.V.C. Control Cables is 19/22 (No. 9 A.W.G.) and 19/25 (No. 12 A.W.G.) but any desired stranding can be furnished to order and cabled into any required number of conductors.
Insulation The insulation of the individual conductors is the same type as that on the power cables described on the previous pages with the exception of the outer braid which is a color coded cotton braid to obtain circuit identification. When furnished for single conductor use asbestos braid replaces cotton braid. Impregnated felted asbestos walls seal the varnished cambric from heat, flame and oxidation. Moistureproof tape is wrapped over the cabled conductors and the
outer covering of tough, braided asbestos yarn is finished with heat, flame and moisture resisting compounds.
Coding The individual wires are braided in colors according to the NEMA standard color code for multi-conductor cable, which is reproduced below. Special color combinations can be furnished to specification.
Lead or Armor Covering These cables may be made up with either lead sheath, armor, or lead sheath and armor covering. Synthetic sheathing is optional also where temperatures permit.
Finish The standard finish of the outer braided asbestos jacket is a black, flame, heat and moisture resisting compound.

POWER CABLE
NEC TYPE AVA--ROCKBESTOS A.V.C. 600 TO 5,000 VOLT RATINGS
S`NC. CONDUCTOR--STRANDED
APPLICATIONS
Rockbestos A.V.C (N.E.C. Type AVA) Power Cables are designed to operate at voltages from 600 to 5000 volts. They are especially recommended for circuits ex posed to severe operating conditions in power stations, steel mills, refineries, tanneries, smelters, etc. and for apparatus which operates under high ambient temper atures.
On the higher voltage rated cables, suitable copper shielding tapes may be specified to eliminate effects of corona on the primary dielectric--the varnished cam bric. Voltage rating of all Rockbestos Hi-I A.V.C. Power Cables is maximum phase to phase voltage. This applies to either grounded or ungrounded systems.
The cables listed in this section have ample moisture resistance for average conditions, but if there is a pos sibility that circuits may be submerged in water for long periods, use lead sheathed constructions in the AVL section of this catalog. The wires and cables in this section are approved National Electrical Code Types, listed by the Underwriters' and fulfill the re quirements of NEMA for Asbestos-Varnished Cambric wires and cables.

SWITCHBOARDS AND PANEL BOARDS
Millions of feet of Rockbestos fireproof A.V.C, (N.E.C. Type AVB) Switchboard Wire have been used by switchboard manu facturers, power stations and industrial plants since we originated and patented the A.V.C, type. Fine appearance is assured complet ed boards because it can be bent at right angles without cracking the braid. Rockbestos A.V.C. Switchboard Wires have a maximum operating temperature of 90C (194F) and ate listed by the Underwriters' Laboratories. They comply with the NEMA Small Wiring for Switchboards Standard and ate approved by Factory Mutual Lab oratories, switchboard manufacturers and power companies. See Page 42 for Rockbestos synthetic and asbestos insulated switch board wires, N.E.C Type TA constructiohs.
MOTOR LEADS Mill motors and other heavy duty stationary and traction types use Rockbestos A.V.C, Motor Lead and Apparatus Cable for pro tection against conductor-heating overloads and high ambient temperatures. This cable retains its flexibility indefinitely because it won't dry out with heat or age, won't rot or bloom from con tact with oil or grease and won't burn or carry flame. These per formance-protecting characteristics make it ideal for motor wiring in steel mills, generating stations, all types of coal mining equip ment, industrial plants--and numerous electrical apparatus app lications.

THE QUESTION OF MOISTURE
Article 310, Chapter III, of the National Electrical Code under the heading of "Conductors" states that the AVA and AVB type wires shall be used in dry locations only and the AVL type should be used in wet locations. In clarifi cation of these limitations, Article 100 in Chapter I defines a dry location as being one not normally subject to damp ness or wetness--and goes on to say that a location classified as dry may be temporarily subject to dampness or wetness as in the case of a building undet construction. Under this regulation AVA and AVB types can be used where occa sional moisture is present, for example moisture which is usually the result of condensation.
This is as it should be! Heat and moisture in conduit app lications cannot be dissociated. Where heat is present for any period of time, a moisture condition sooner or later will appear. Usually the condition occurs during periodic shut downs, as in the case of weekend holidays, where sudden changes in conduit temperatures from hot to cold result in condensation. Again condensation can and does occur where a sufficient temperature differential exists along the conduit. A case in point would be a single conduit run from a high temperature furnace area to a cold outside wail. A certain amount of air circulation exists within the conduit, and
g moisture is precipitated at the colder end--a condition iden
tical with precipitation on cold water pipes in basements during a humid summer day. Rockbestos A.V.C. (N.E.C. Type AVA) was designed to meet these conditions as it is constructed of asbestos, tho roughly impregnated with heat, flame and moisture resistant compounds, together with high dielectric varnished cambric
tapes. Since the inception of this design, Rockbestos Research has been running continuous laboratory projects simulating act ual field service conditions on various A.V.C. constructions. A.V.C. constructions installed in conduit were subjected to steam, heat, a combination of heat and water--even com plete submersion for extended periods to simulate emer gency conditions. The results proved conclusively that Rock bestos A.V.C. has not only a built in factor of safety against "moisture" as defined by the National Electrical Code but substantial ability to withstand extreme conditions encount
ered in conduit applications as well. Since then millions of feet of Rockbestos A.V.C. have been used successfully in industry to further prove its dependable operation. Where a portion of a circuit in conduit is subject ed to heat and another portion subjected to water, as in the case of steel mill furnace control circuits running partially through under-slab duct systems, AVL is recommended.

ASBESTOS BRAIDS
Standard Rockbestos A.V.C. Type AVA wires and cables are supplied with a black asbestos braid and Type AVB with flameproof gray cotton braid, but these wires and cables can be furnished with other braid materials and colors for other special applica tions. This picture to the right shows one of the big cable braiders. The carriers and their spools of as bestos yarn weave in and out in a may-pole dance to form the rugged heat and flame resistant outer braid. Cable diameters, yarn sizes and the number of ends and picks per inch must be taken into consideration to obtain proper coverage and allowance for flexing action in service.
COTTON BRAIDS
This close-up of a high speed braider is shown ap

with the current requirements of ASA specifications
for Cotton Braid for Insulated Wire and Cable for
General Purposes--Code Braids (commonly known
as NEMA Class B Braid).
Other materials such as rayon, glass, silk, etc. are also

HOW W INSULATION . .
FELTED ASBESTOS WALLS
This close-up of a double insulator to the left shows the operation performed by the battery of insulating machines pictured below. Single or double heads, car rying the cheeses of fluffy asbestos roving, revolve around the conductor to apply a uniform wall of asbestos which is then impregnated and compressed to specified thicknesses. This dense wail, resistant to heat, flame, grease, oil and fumes, is the basis of the insulation of Rockbestos Ail-Asbestos and A.V.C. type wires and cables.
IMPREGNATING COMPOUNDS
In general the felted asbestos insulating walls of all Rockbestos wires, cables and cords are impregnated with a chemically neutral, black insulating compound which is heat, moisture and flame resisting. Wherever identifying colors are required on wires having no outer braid, the insulation can be furnished in white, black or plain colors. In special cases where a wire will be exposed only to extremely high temperatures and no moisture, white compound may be used in the impregnation of the felted asbestos walls and for the finish of the braid. See page 45 Rockbestos Extra Flexible All-Asbestos Apparatus Cable.
HIGH DIELECTRIC TAPES One of the large wrapping machines which applies varnished cambric or synthetic tapes to various types of Rockbestos A.V.C. cables.

ASBESTOS * OUR BASIC
RAW MATERIAL
In entering upon i description of Rockbestos wires and cables, a brief outline of the characteristics of asbestos, the chief material used in their insulation, is a logical beginning. Asbestos is a mineral, consequently inorganic in its na ture, and in this principal feature different from all other types of material in use for insulating wires and cables. Asbestos fibres are solid, that is to say they have no cap illary opening through their center like cotton, wool or other organic fibres. Because of this fact, there is no ten dency for individual asbestos fibres to act as capillaries if their ends are exposed, and it only becomes necessary to fill the voids of interstices between the fibres to pro duce a relatively impervious layer. Asbestos has demonstrated its ability to withstand time without the deterioration that occurs in wwu fumn ui' electrical insulating materials such as rubber and the gen eral dass of organic fibres. Furthermore, it will not cot or carbonize under any conditions. It may be fairly stated indeed that asbestos is ageless, and time, as every engi neer well knows, is a much more exacting test of a material than almost any laboratory accelerated life test which can be made. During the centuries since the as bestos was formed, it has been exposed to high earth temperatures and, as earth cooled, to moisture and the wide variety of earth acids and alkalis, all with no apparent change in any of its properties. We have investigated the world's sources of asbestos to find and secure the softest, silkiest, purest, long fibred asbestos -. and we find it in certain deposits of Chrysotile (Serpentine Group)--the aristocrat of the asbestos family.
Chtysotile is a hydrated magnesium silicate which occurs in crystalline fotm in veins or striations in the mother rock and is w-idely distributed. Each crystal is a "fibre", square in cross section, having a diameter of about 1/500, 000 inch and a length equal to the width of the vein. There ace a number of sources of Chtysotile fibre, the principal ones being Rhodesia, Canada, Russia, Arizona and Australia. The largest deposits are in Rhodesia and Canada. Asbestos retains its strength and fibrous fotm undet alt conditions except extremely high temperatures. Chtyso tile asbestos in crude (unopened form) begins to lose some of its water crystallization at about 450C and is almost completely dehydrated at 950C. It fuses at about !500C. When applied to wires or tables in felted term, its low heat conductivity enables it to withstand melting the copper conductor by passage of high currents without material loss of its mechanical strength. Tests of fabrics woven of Chtysotile asbestos show that after three hours at 500C they still have their original tensile strength. Asbestos, after it is mined, is broken up, fiberized and cleaned. It is then combed and carded into soft, fluffy roving. In this form it is applied to the conductor, impregnated with neutral insulating compounds, and compressed into the felted wall which is Rockbestos insulation that is not only fireproof but practically impervious to the destruc tion normally caused by heat and moisture, oil, grease, corrosive fumes oc age. What a material to use whete endurance and resistance to deterioration are so important!
Hard as a rock in the vein, asbestos is soft as silk when fiberized. Each silky fiber is a crystal l/500,000th of an inch in diameter.
A million-year-old handful! This asbestos has been completely fiberized and prepared and is now ready to be carded into roving.

ROCKBESTOS is the name for a wide line of wires, cables and cords, including more than 125 different standard constructions, which have been designed and developed to give long and depend able service under severe operating conditions. Early in 1918 a small group of Rodcbestos Elec trical Engineers and Chemists perfected a method of applying asbestos to wires and cables as a heat resisting electrical insulation. This first step result ed in the production of wire that industry and elec trical engineers had been looking for. Here was an insulated conductor resistant to high tempera tures, aging, corrosive fumes, grease, oil and flame. Success from the start--and just the beginning for this company which was later to distinguish itself to be the only company in industry devoted ex clusively to the manufacture of permanently insu lated wires and cables. Rockbestos grew along with the then rapidly growing electrical industry, salv ing its electrical insulation problems as they became
apparent with this unique mineral, ASBESTOS. Other materials ace often combined with asbes tos, i.e. Varnished cambric. Synthetics, DuPont "Teflon" Tetrafluoroethylene resin, cotton, cayon, nylon and glass, to provide special characteristics. Two broad lines of permanently insulated wires, cables and cords--Rockbestos A.V.C. asbestos-var nished cambtic insulated (N.E.C. Types AVA and AVB) and Rockbestos ALL-Asbestos (N.E.C. Types A, AA, AI, AIA and AF)--have been de veloped for innumerable industrial applications. Rockbestos engineering and research are constantly abreast of electrical problems in both science and industry, providing answers through the develop ment of trouble-free, ageless electrical insulations designed for each specific application. May we offer you our research facilities for the development of special wires designed to meet any unusual re quirements.
