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. 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 dr 3 AWG is tne smallest cable that C2n 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 for llO^C. Conductor temperature tor the desired power factor. Graphs--Locate the intersection of load amperes and con ductor size. Note approximate conductor temperature. 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 for next lower temperature below that read from graph. Example 3--To find proper conductor size for 325 foot power circuit 440 volt 3 phase, 325 amperes, 80% power factor, 3CC ambient, voltage drop not to exceed 3%: Per missible voltage drop is 440 x .03 = 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 1.62 volts drop per 100 feet of conductor at 100% power factor. Con ductor will be operating at approximately 95C 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. . | POWER FACTOR CORRECTION FACTORS (Based on Conductor Temperatures) Conductor Size AWG or MCM 14 12 10 8 6 5 4 3 2 1 1/0 2/0 3/0 4/0 250 300 350 400 500 600 700 300 1000 90% Power Factor 60C .91 .91 92 . .92 .94 ~ .95 i .96 .97 .99 1.02 1.10 1.14 1.20 1.26 1.32 1.39 1.46 1.52 1.63 1.76 1.87 1.96 2.13 75C 91 .91 .91 991.01 1.10 1.14 1.18 1.25 1.30 1-37 1.43 1.49 1.60 1.72 1.82 1.90 2.07 1I0C .91 .91 .91 .92 .94 .95 .95 .96 .98 1.00 1.07 142 1.16 1.21 1.28 1.34 1.40 1.45 1.55 1.65 1.74 1.83 1.98 80% Power Factor 70% Power Factor 60C Conductor Temperature 75C U0C 60C 75C U0C .81 .81 .81 .72 .72 .72 .81 .82 .83 .31 .82 .83 .81 .72 .82 73 .83 .74 .72 .73 .74 .72 .73 .74 .85 .85 .85 .77 .77 .76 .87 .87 .86 .79 .78 .77 .88 .90 .88 90 .87 .81 .89 83 .30 .82 .79 .81 .93 .95 .92 .95 .91 .85 .93 .38 .84 .87 83 .86 1.08 1.06 1.04 1.03 1.02 .99 1.14 M2 1.09 1.10 1.08 1.04 1.20 1.19 1.15 149 1.16 142 1.30 1.28 1.22 1.30 1.27 1.20 1.38 1.35 1.31 1.38 1.55 1.30 1.48 1.44 1-39 1.51 1.47 1.40 . 1.57 1.53 1.47 1.61 1.57 1.50 ' 1.65 1.61 1.54 1.71 1.66 1.58 1.82 1.76 1.69 1.90 1.84 1.74 1.98 1.93 1.81 2.10 2.03 1.90 2.13 2.07 1.93 2.27 2.20 2.04 2.26 248 2.04 2.42 2.33 2.17 2.50 2.42 2.25 2.70 2.61 2.42 60% Power Factor 60C .61 .62 .63 .64 .67 .69 -71 .74 .77 .81 .97 1.05 145 1.26 1.37 1.51 1.63 1.74 t.95 2.18 2.38 2.54 2.87 75C .61 .62 .63 .64 .67 .69 .71 .73 .76 .79 .95 1.03 1.12 1.24 1.33 1.47 1.58 1.68 1.38 2.10 2.30 2.44 2.76 110C .61 .62 .63 .64 .66 .68 .69 .72 .74 .77 .92 .98 1.06 147 1.28 1-39 1.50 1.59 1.78 1.94 241 2.26 2.54 RBB 03024 CONDUIT SIZE TABLES I o 6 TABLE EL Cable Size Cable Diam.

CABLE In general, no special precautions are necessary in the r.sulacing and waterproofing of terminals or joints in A.VC. cable runs. This is because or the additional ther mal cipiciry of thermal ends and ;oincs. plus the fact :ha: in general such terminal ends or 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, ic is advisable to build up the joint with layers of varnished cambric tapes prior to the application of the rubber and friction tapes. In wet locations where lead covered A.V.C. cable is used, ihe same practice is used except that the tnction tape is treated with a giyptal varnish or Irvington oil stop. The illustration below shows a recommendation for such a cable splice. In ail hish voltage. :..s. ovs: 600 voits. all t.-rmir.al ends and joints should be insulated with varnished ca.r.oric :a?e before applying the rubber or friction tapes. The friction tape should be created with either giyptal varnish or Irvington oil scop. 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 w-ith friction rape. . kt SUGGESTED METHOD OF SPLICING AVA OR AVL CABLE 1. Prepare able ends and joint with standard soldered or mechanical connector. 2. Paint connection and adjacent insulation with compound such as giyptal varnish or Irvington Oil Stop. 3. Apply layers of varnished cambric tape with giyptal varnish or Irvington Oil Stop between layers to fill up space even with braid or lead sheath. 4. Apply two layers of rubber tape, and then two more layers of friction tape with ^giyptal varnish or Irvington Oil Stop between all layers and over surface. Extend rubber and friction tape over at least two inches of the cable sheath or braid which previously had been painted. 5. In case of lead sheathed cable where joint will be in wet location, a lead sheath and wiped joint may be used. be made near each end of the sample of which the average shall comply with the requirements giv en in the tables. The measurements of cable % inch diameter and smaller shall be made with a ratchet micrometer having J4 inch diameter faces. For cable larger than % inch diameter the meas urement shall be made w'ith a circumference tape. Each determination, when made with a micro meter, shall be the average of two measurements made at right angles to each other.

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 required 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. CONSTRUCTION 1 Special Alloy Wires 2.

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 hear 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.

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 ft safeguard against frozen water pipes making 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 dow 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. jteel miils use it around roll-necks 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 do feet. The recommended wattage limit is i watts per foot. At 110 volts a 60 ft. length is rated at -00 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 4-10 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 eted 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.

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 or 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 not inter fere with prompt access to the vault for service rescoraric Supplied with standard concentric stranding or segmentconductor.

Secondary NetA 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, rhe 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 copper temperature for extended periods, although in emergency conditions much higher temperatures will not endanger the cable.

ASBESTOS BRA 10 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 wice 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 AU-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 aote. 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 dissimtlat 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 alloy 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.

OVENS, HEATERS, FURNACES. INDUSTRIAL DRYERS. AIR CONDITIONERS, APPARATUS, ETC. The wiring of the control systems of early automatic coal and oil burning installations formerly gave frequent trouble. To get shot runs it was often installed close to, or actually resting on, hot water or steam pipes and the hear naturally deteriorated ordinary insulated 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 rough beams all tend to damage the insulation. With these conditions in mind, and w-ith 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 hearproof and will not dry out under hear 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 for any similar application where a low voltage, muiti-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 1214 mil wail 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.

Because of the excellent properties of these thermoplastics .the appli cation for this new construction was extended to control cir cuits exgpsed to weather and to installations requiring 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 core wrapped with a sheath tape. A tough outer covering of Rock- hide (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 1948, 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 vou can use smaller conduit and fittings to save on steel and installa tion costs.

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 insulation just above the socket cracks and crumbles, per mitting the wires 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.

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 gjie 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 ideal 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 .irotriru* and tor the wiring or omernnc m.icn>rc*<, 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 Cord 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.

A;bcc:c; *vir wac nriginaily oroduieu bv auuiua two Of three braids of asbestos yarn on the wire *iid fuujhl: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 Baked 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 painted on after the wall is formed. That means chat, through repeated neatg -nd cooling cycles, die compound car. 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 Baking 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 totting, corrosive fumes.

These wires are listed by Underwriters' Laboratories as Type A1A wire. Rockbestos Heat Resisting Fixture Wires are approved by the Underwriters' Laboratories for lighting fixtures and bear their labels. The impregnated asbestos insulation withstands the high socket temperatures developed by high wattage or flush type fixtures without drying out or becoming hard or brittle. This type of insulation also eliminates fire hazard as it is resistant to flame as well as heat. Furthermore, it is moisture resisting, an important factor where fixtures hang in damp or humid locations. NEC TYPE AFC AND AFPD MAX.

The constructions illustrated on these two pages oifer a selection of either cot ton or asbestos braid. The flexible cords on page 51 are approved bv Underwriters' Laboratories for lighting fixture wiring under rhe tvpe svm- bols shown. The 300 volt All-asbestos Flexible Cords shown on page -19 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.

Switchboard Wire is designated as Na tional Electrical Code Type AVB, has a maximum operating temperature of ?0rC (19*rFj and is listed by the LkvJcr* -.vekers' Laboratories. It complies with the NEMA Smali Wiring for Switchboards Standard and is approved by Fac tory Mutual Laboratories, switchboard manufacturers and power companies. It is used for switchboards, radio and tele vision transmitters, motor driven rheostats, control panels, for motor starters, elevators, Ere doors, cranes, induction heating apparatus, oil burning boiler units, etc. Fine appearance of completed boards is also assured because ) Rockbestos A.V.C. Switchboard Wire can be bent at right angles without cracking the braid. This desirable characteris tic is contributed by the felted asbestos wall of insulation VAR-JiSf-SO cambric asbestos HamEPRCOF cohon bsaio which acts like a cushion beneath the braid and gives slightly when 3 sharp bend is made. For this reason boards can be rvv'm r"::h other types cf switchboard must be handled carefully if bieaks are to be avoided. On switchboards installed in locations where the wiring is ex posed to very high temperatures, we recommend the use of our Table C, Rockbestos A.V.C Lighting Wire, on page 13 in this catalog. Braid Colors: Standard finish colors: Gray and black. Authorized stock items: Gray. Other colors or striped patterns can be furnished on special order.

Concrol Cable iilciscratei is one or :he many mukiconduccor cables designed to meet specific requirements in control and power circuits. They are made up as shown or with either lead sheath or armor only as specified and in ratings ranging from 600 to 5000 volts. (Synthetic sheath ings may also be specified for concrol cables where temperatures permit.) This type of cable not only protects operation of circuits exposed to 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 w:;t..u 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 or 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 or 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 wall of felted asbestos to complete the A.V.C. construction serving as a baffle between the varnished cambric and heated conductors. mr.

APPLICATIONS The three conductor Power Cables iisted in uiis 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.

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.

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.

SWITCHBOAROS 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 are listed by the Underwriters' Laboratories. They comply with the NEMA Small Wiring for Switchboards Standard and are 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 constructions. 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. TYPICAL APPLICATIONS FOR POWEI WHERE SUBJECTED POWER CIRCUITS UP TO 5000 VOtT'SERVICE Standard Rockbestos A.V.C.

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 i 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 under 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 ofcondensation. 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 wall. 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.

These coverings when applied comply with current NEMA specifications for metallic cov erings. Metallic and synthetic sheathings may be used on Rockbestos A.V.C Pow er and Control constructions in ratings ranging from 600 to V>00 volts Metallic Braid Coverings The braiders weave coverings of wire just as wc,; as those of ^otton ur -o bestos yarn. This armor braider is weaving a protective basket weave metai braid over the synthetic sheath of the cable. Such metals as Aluminum, Sreel and Bronze are used on these armor braiders to form heavy Jutv coverings for circuits requiring greatest mechanical strength and abrasion resistance. Electrical shields of tinned copper can also be applied when specified. Interlocked Armor Coverings Cables covered with either steel ot bronze interlocked armor are not only protected from exposure to severe heat and moisture, but their use elimi nates the need for conduit giving increased flexibility to wiring svs:err< The ablw oO jaotcaed uii >st run in troughs, up vertical ri*ci ui <jci and around obstructions. On orders for these types of special coverings, give complete specifications and state cutting lengths on order. EXTRUDED LEAD and SYNTHETIC SHEATHS Lead sheaths such as are required on Rockbestos A.V.C. Type AVL Power Ca bles are extruded by lead presses like the one pictured at the left. A pressure of approximately 1,000 tons per square inch is used to apply the lead sheaths to the cable. These moistureproof sheaths ate used on Rockbestos standard Power, Con trol and Industrial Heating Cables. The Tuber pictured to the right is extrud ing a thermoplastic synthetic sheath over a large asbestos insulated shipboard cable. Other tubers similarly sheathe or apply synthetic insulation to small wires and cables. 8 RBB 02958 APPLY BRAIDS and FINISHES * ASBESTOS SRAIOS Standard Rockbestos A.V.C. Type AVA wires and cables are supplied with a black asbestos braid and Tvpe AVB with flameproof gray cotton braid, but these wires and cables can be furnished with other braid materials and colors for ocher special applica tions. This picture to the righc 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 plying a braid of cotton to a Rockbestos A.V.C. Type AVB Switchboard Wire. The weaving action of this machine is accomplished by rotating two levels of car 9 riers in opposite directions and diverting threads from the lower level alternately over and under the threads from the top level by a series of cams. Rockbestos fin ished cotton braids as used for outer coverings comply with the current requirements of ASA specifications for Cotton Braid for Insulated Wire and Cable for General Purposes--Code Braids (commonly known as NEMA Gass B Braid). Other materials such as rayon, glass, silk, etc. are also braided on this type of machine. STANDARD AND SPECIAL FINISHES ASBESTOS BRAIDS are finished with a suitable flame and heat resisting compound or saturated and finished with a flame, heat and moisture resisting com pound, as specified. COTTON BRAIDS are finished with a flame and heat resisting compound or saturated and finished with a flame, heat and moisture resisting compound, as specified. On any of the standard wires shown in this catalog, special cotton twine, linen, glass or rayon braids can be substituted if necessary. Also a variety of special *2 braid finishes such as lacquer, wax, asphalt or alumi num paint can be applied overall. 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 as bestos which is then impregnated and compressed to specified thicknesses. This dense wall, resistant to heat, flame, grease, oil and fumes, is the basis of the insulation of Rockbestos All-Asbestos and A.V.C. type wires and cables. IMPREGNATING COMPOUNDS In general che 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 AU-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. Rotating heads apply tapes selected to provide specified mil wall thickness es, desired lap and length of lay required by the type of cable in process. Varnished cambric tapes are being applied over the first felted asbestos wall of the Rockbestos A.V.C. Power Cable in the machine.

Rubber, for instance, while known to be high in moisture resistance, was af fected by high temperatures which caused it to become dry and porous iimiting its length of effective service. The life of straight varnished cambric insulations too by Rockbestos and used commercially is synonymous with National Electrical Code Types AVA, AVL and AVB. That is, A.V.C. finished w-ith asbestos braid is Type AVA, with lead sheath is Type AVL and w-ith cotton braid is Type AVB. was seriouslyaffected by high ambient temperatures which :--.s h-.i rc*Y tended to cause deterioration of the tapes. Early asbestos insulations proved unsatisfactory because they consisted only of a series of asbestos braids filled with paint or other compound.

Recognizing that high temperatures and moisture were The Code in rating this original Rockbestos A.V.C. con the major threats to the lire of insulations, Rockbestos struction permitted it a higher cemperature limit than Engineers designed and developed their A.V.C. construc ordinary insulations because its impregnated felted as tion.

RBB 02955 5 ASBESTOS OUR BASIC RAW MATERIAL In entering upon a 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 v/irhout the deterioration that occurs in fui.w of electrical insulating materials such as rubber and the gen eral class of organic fibres. Furthermore, it will not rot 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 Chryso- tile {Serpentine Group)--the aristocrat of the asbestos family. Chrysotile is a hydrated magnesium silicate which occurs in crystalline form in veins or striations in the mother rock and is widely 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 are a number of sources of Chrysotile 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 form under all conditions except extremely high temperatures. Chryso tile asbestos in crude (unopened form) begins to lose some of its water crystallization at about 450C and is almost completely dehydrated at 850C. It fuses at about When applied to wires or cables 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 Chrysotile 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 or age. What a material to use where endurance and resistance to deterioration are so important! Hard as a rock tit 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.

A. ii m RBB 02950 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 Rockbestos 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, solv ing its electrical insulation problems as they became apparent with this unique mineral, ASBESTOS. Other materials are often combined with asbes tos, i.e. Varnished cambric. Synthetics, DuPont "Teflon" Tetrafluoroethylene resin, cotton, rayon, nylon and glass, to provide special characteristics. Two broad lines of permanently insulated wires, cables and cords--Rockbestos A.V.C. asbestos-var nished cambric 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. 6 1 RBB 02949 .. Filo No. 31-C -672 a lio No. 31-C-679 7?
