RBB 00471 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'' Tettafiuoroethylene 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.

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 other forms 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 faicly 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. 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, haviog 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 1500C. When applied to wires or cables in felted form, 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 in the vein, asbestos is soft as silk when fiberized. Each silky fiber is a crystal !/500,000th of an inch in diameter. A m'tUion-year-old handful! This asbestos has been completely fiberized and prepared and is now ready to be carded into roving. RBB 00475 WHY ROCKBESTOS A.V.C. WAS DEVELOPED Since die early days of electrified industry, there has been a definite need for an electrical conductor insulation which would operate dependably in elevated ambient temperatures. High ambient temperatures were a prob lem then as they are today, and the performance of or* dinary wires and cables at that time was restricted by the very nature of the materials used. 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 limiting its length of effective service. The life of straight varnished cambric insulations too was seriously affected by high ambient temperatureswhich 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 major threats to the life of insulations, Rodcbestos Engineers designed and developed their A.V.C construc tion. This A.V.C. construction used as a basis dense felt ed walls of thoroughly impregnated asbestos to form a continuous insulation which would permanently resist heat, flame and moisture. High dielectric varnished cam bric tapes were added as an insert between the felted as bestos to give added dielectric strength and moisture resistance. In this combination the felted asbestos also provided protection for the Varnished Cambric tapes against mechanical damage, deterioration from oxida tion and prevents the formation of a continuous carbon path from conductor to ground. This basic construction was covered overall with either impregnated asbestos or flameproof cotton braids. This new Rodcbestos A.V.C construction was designed primarily to safely and depen dably carry electrical loads in high ambient locations and to withstand additional operating hazards such as attacks of chemicals, oils, grease and fumes. Here was an insu lation designed to give a long life of dependable oper ation under severest conditions. Since the introduction of Rockbestos A.V.C. wires and cables in 1927, many millions of feet have been installed throughout the world under normal and abnormal oper ating conditions. These installations have covered a wide range of high temperatures and moisture conditions in practically every known industry. Rockbestos Field Engi neers have constantly checked many of these installations in various industries since 1927 to check field conditions against long time tests run by our Research Laboratory to confirm the ability of Rockbestos A.V.C. to meet un usual service conditions. Because of their successful oper ation, these asbestos-varnished cambric wires and cables were included in the National Electrical Code in the 1937 Edition and designated as N.E.C Types AVA, AVL and AVB. The trade name "A.V.C" as registered by Rockbestos and used commercially is synonymous with National Electrical Code Types AVA, AVL and AVB. That is, A.V.C finished with asbestos braid is Type AVA, with lead sheath is Type AVL and with cotton btaid is Type AVB. THE HM STORY Maximum current earning capacities of insulated con ductors are determined within practical limits by the mairtmiifn temperature the insulation will stand without undue deterioration. The Code in rating this original Rodcbestos A.V.C. con struction permitted it a higher temperature limit than ordinary insulations because its impregnated felted as bestos walls safely resisted deterioration under high am bients and the heat from current loads. Chapter 10, Ta bles I and II, under "Allowable Current-Carrying Capadries at 30C" list Rockbestos A.V.C Type AVA con struction with greater current carrying capadty size for size than for cables with ordinary insulations. The prac tical advantages of Rodcbestos A.V.C. begin here. As ambient temperatures increase and correction factors are applied, A.Y.C is de-rated far less than ordinary con structions, all because of its insulation. At 70C, for instance, other types of Insulations are de rated as much as 65% while Kockbestos A.V.C. is de rated only 29%. At ambient temperatures in excess of 85C a limiting point for other types of insulations, Rockbestos A.V.C. rated at 110C continues to provide permanent protection for electrical circuits. Plant layouts and expansion programs ate given greater flexibility by installing Rodcbestos A.V.C. because not only does it provide greater current carrying capadty for intermittent demands and future load growth in existing dreuits, but the installation of heat generating equipment is not restricted by its nearness to vital electrical circuits. The fact that you can use a smaller sized cable to carry a given load can start a whole series of cumulative sav ings. Smaller cable means smaller conduit and fittings.

(Code Type AVA) Power Cables are available in voltage ratings of 600 to 5000 volts. They are designed to protea circuits that must operate without failure un der continuous exposure to high temperatures and other severe operating conditions. Copper shielding can be provided where re quired. They are available in single or multi-conductor construc tions with either lead sheaths or asbestos braids. Interlocking armor can be furnished to special order. Rockbestos A.V.C. (Code Type AVA) Power Cable constructions are approved by the Na tional Electrical Code, listed by the Underwriters* Laboratories and conform-'to NEMA standards. CONDUIT WIRING AROUND FURNACES, OVENS, SOAKING PITS, BOILERS, ETC. Rockbestos A.V.C Power Cables and Lighting Wires can be run in conduit as they are built to withstand the normal moisture con ditions resulting from condensation caused by heating and cooling cycles. In cases where power and lighting circuits are exposed to high temperatures in combination with excessive condensation or complete submersion, use lead sheathed Code Type AVL. LIGHTING AND POWBt CIRCUITS Rockbestos Hi-I A.V.C (Code Type AVA) Lighting and Power Cables are high temperature cables. This A.V.C construction-- rwo layers of impregnated felted asbestos encasing the varnished cambric--permits continuous operation at copper temperatures of 250F (110C), thus making Hi-I cables ideal for high ambient "Hot Spot** locations or, in normal ambient installations, per mitting the use of smaller cables with consequent savings of cop per, conduit, fittings and man-hours of labor as compared with cables having ordinary insulation. 6 RBB 00477 LIGHTING and CONTROL CIRCUITS HIGH TEMPERATURES ** RHEOSTAT AND APPARATUS WIRING Rodcbestos All-Ast>cstos Rheostat Wires and Cables were design ed primarily for open wiring. Operating temperatures of 125C for 600 volt ratings and 200C for 300 volt applications can be safely met as constant elevated temperatures will not cause the compounds to fall away or flake off even through repeated heat ing and cooling cycles. It is especially recommended for grid jumper connections from grids to faceplates, ovens and element leads on well type anneal ing furnaces and open wiring exposed to extremely high temper atures, corrosive fumes, grease, oil ot fire hazard. SWITCHBOARDS AND PANEL BOARDS Millions of feet of Rodcbestos 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.

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 or control appara tus are exposed to heat oc 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 Conductors The standard stranding; 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 to heat, corrosive fumes, oil, grease and flame and has ample moisture resistance for installation either open or in conduit. Under exposure to flame this cable will maintain vital control and alarm system circuits for longer periods than other types of insulated cables. SPECIFICATIONS 1. Tinned copper conductor 5.

Control Cable illustrated is one of the many multi conductor 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 3000 volts. (Synthetic sheath ings may also be specified for control cables where temperatures permit.) I 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 mote easily accessible. The felted asbestos insulation, impregnated with heat, flame and 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 or over and around obstructions. Its flame and heat resistant structure will also maintain vital alarm and control system ciri cuits for longer periods under exposure to flame than other conventional , trpcs- The cable illustrated on this page is a special construction which is typical of ! many "specials" designed by Rockbestos to meet severe oc 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. I Lead sheathing for protection against immersion or excessive condensation. I 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. 16 RBB 00487 ROCKBESTOS A.V.C 600 VOLT SWITCHBOARD WIRES t NEC TYPE AVB--ROCKBESTOS A.V.C.

ELECTRIC STOVE BUS CIRCUITS, ELEMENT LEADS ON WELL TYPE ANNEALING FURNACES AND OPEN WIRING EXPOSED TO EXTREMELY HIGH TEMPERATURES, CORROSIVE FUMES, GREASE, OIL OR FIRE HAZARD. Asbestos rheostat wire was originally produced by putting I two or three braids of asbestos yam on the wire and finishing 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 instil* lation was completed, spoiling the appearance of an otherj 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 parr of the insulating wall, not painted on after the wall is formed. That means that, through repeated heating and cooling cycles, the compound can never 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 Rockbescos 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 24.

It had a distinct advantage in its small diameter. Because of this feature, it has also found usage in some in dustrial instrumentation and control circuits in conduit when its use does not conflict with the requirements of the National Electrical Code. Additional uses for this wire are foe automotive bus engine compartment wiring and diesel locomotive circuit wiring. Rockbestos 1000 Volt Lead Wire is constructed with non flowing, thin-walled, helically applied synthetic tape and felted asbestos insulation. This construction covered with a glazed cotton braid lacquer finish results in a small diameter wire with high dielectric strength. This wire strips easily and is resistant to heat, cold, flame, moisture, grease and oil.

It is similar in con struction to the 1000 Volt Lead Wire shown on this page with the exception that it is covered with a lacquered glass braid overall and is recommended for applications in which abrasion resistance requirements are less severe than for Table EMA. This hookup wire was originally developed along govern ment specifications for a glass braided wire suitable for use within electronic devices and instruments which would have high dielectric strength, small diameter and stability in a broad range of operating temperatures. Like Table EMA on this page, Rockbestos 1000 Volt ACA Hookup Wire is resistant to heat, cold, flame, moisture, grease and oil.

COATED STEI1 AKMOK FOR LOW VOLTAGE SIGNAL, INTERCOMMUNICATIONS AND ALARM SYSTEMS, FUEL BURNER CONTROLS, GAS BURNER SAFETY PILOTS, 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 shcit runs it was often installed dos* to, ot actually resting on, hot water or steam pipes and the heat 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 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 sttong mechan ically because of its firm felted asbestos insulation and its rugged, abtasion 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. Neicher can tats 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, multi-conductor cable is required. Rockbestos Thermostat Control Wire is designed to be useJ at low voltages, usually fed by a step-down transformer. For this application the 12 i/2 mil wall insulation is generally used, rfowever, 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 vole circuits a minimum insulation thickness of 31 mils is recommended. Data for cables with all three insulations is listed in the table below.

ETC. This Rockbestos heating cable was originally developed to force the growth of early spring plants in hothouses. After its introduction to florists, market gardeners and amateur horticulturists, it found its way into industry as a useful heat source for the distribution of even mild heat. It performed to better advantage and more economically than spot or strip heaters. Pliable, easily bent and formed, it can be threaded through apertures or made to 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 making unnecessary the rearrangement of piping or costly replacement. Waste pipes, eaves troughs and down spouts can also be kept free and clear 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 clogged conveyor pipes. Wet pipe sprinkler systems located in unheated areas are easily heated and kept at non-freezing temperatures that assure positive operation. Steel nulls use it around roll-necks to prevent rhe 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 60 feet. The recommended wattage limit is 7 watts per foot. At 110 volts a 60 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 piiced 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 make up heating cable characteristics to your specification. Furnish complete details concerning temperature desired, heat dissipation, etc. with inquiry.

Lead Sheath 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 29. 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.

The current is turned on only when rain or snow is expected and the temperature drops below freezing. The kits come in 20, 40 and 60 ft. lengths (the latter com plete with 8 shingle damps), depending upon the overhang of the eaves. With average house construction one 60 ft. kit will protect 20 running feet of roof. PIPE HEATING: Electric heating cable can easily be applied to water pipes, whether buried in the ground or exposed, to give positive protection against the damage caused by freeze-ups or broken pipes. For maximum coverage of pipe length, the cable should be applied parallel; but where greater protection is needed in low temperatures, the spiral method can be used. When applied this way, the cable will increase the heat applied because of the greater concentration of heat. SOIL HEATING--HOT BEDS and COLD FRAMES: The heating kit serves as a dependable heat source in hotbeds, cold frames and propagating benches to stimulate faster growth for plants and cuttings. Cuttings will root and plants will grow 20 to 30 times faster this clean scientific way. Once the cable is installed, it may be left in place indefinite ly. To insure proper seed germination a thermostat is necessary to accurately control the heat. For this purpose we recommend using Rockbestos Weatherproof Thermostat LT-56 adjustable for temperatures of \0T00F.

Five feet of cord leading from the thermostat U provided for connection to a 110-113 volt AC power source. Secure the thermostat to the surface of the pipe with a suitable wire or cord, passing it through the small "ears" on either side of the thermostat. Simply plug the thermostat cord into your power source and plug the heating cable into the back of the thermostat plug When pipe covering is used, extend pipe covering to cover thermostat, leaving only dial exposed for setting. Set the thermostat for the temperature at which heating is to start (approximately 37F. for pipe heating) and thermostat is ready to operate. HOT BEDS. COLD FRAMES or PROPAGATING BENCH APPLICATIONS: The thermostat may be mounted within the frame itself when air temperature control is all that is requited. When used to control soil temperatures, the thermostat itself may be buried, allowing the dial and setting knob to be exposed for final dial setting.

CABLE In general, no special precautions are necessary in the insulating and waterproofing of terminals or joints in A.V.C. cable runs. This is because of the additional ther mal capacity of thermal ends and joints, plus the fact that in general such terminal ends or joints are in cooler ambient locations than the main run of the cable. In this type of 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 rubber and friction tapes. In wet locations where lead covered A.V.C. cable is used, the same practice is used except that the friction tape is treated with a glyptal varnish or Irvington oil stop. The illustration below shows a recommendation for such a cable splice. In all high voltage, i.e. over 600 volts, all terminal ends and joints should be insulated with varnished cambric tape before applying the rubber or friction tapes. The friction tape should be treated with either glyptal varnish or Irvington oil stop. Where it is necessary either to terminate or make a jomt 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 tape. SUGGESTED METHOD OF SPLICING AVA OR AVL CABLE 1. Prepare cable ends and joint with standard soldered or mechanical connector. 2. Paint connection and adjacent insulation with compound such as glyptal varnish or Irvington Oil Stop. 3. Apply layers of varnished cambric tape with glyptal 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 glyptal 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. 3. In case of lead sheathed cable where joint will be in wet location, a lead sheath and wiped joint may be used. % RBB 00512 BARE COPPER WIRE DATA ALL DATA TO ASTM B-258 RESISTANCE (BUREAU OF STANDARDS) f\ Size AWG Dim. laches Circular Mils LBS/1000' FT/LB OHMS/1000' 1 20C (68F) : Sire AWG 4/0 .460 211.600 640.5 3/0 .410 167.800 507.9 2/0 -365 133.100 402.8 I/O .325 105.600 319.5 1.561 1.968 2.482 3.130 .04901 .06180 .07793 .09827 : VO 3- 0 1 '0 1 .289 83.690 253.3 2 .258 66.360 200.9 3 .229 52.620 . 159.3 4 .204 41.740 126.4 3.947 4.977 6.276 7.914 .1239 .1563 .1970 .2485 1 3 4 5 .182 33.090 100.2 6 .162 26.240 79.46 7 .144 20.820 63.02 8 .128 14.510 49.98 9.980 12.58 15.87 20.01 3133 3951 .4982 .6282 6 8 9 .114 13.090 39.63 10 .102 10.380 31.43 11 .091 8.230 24.92 12 .081 6.530 19.7- 25.23 31.82 40.12 50.59 792! 9989 1.260 1.588 9 12 13 .072 5.180 15.68 14 .064 4.110 12.43 63.80 80.44 2.003 2.525 15 .057 3.260 9.858 101.4 3184 15 16 .051 2.580 7.818 127.9 4.016 16 17 .045 2.050 6.200 161.3 5 064 * 18 19 .040 .036 1.620 1.290 4.917 3.899 203.4 256.5 6.385 8.051 18 20 .032 1.020 3.092 323.4 10.15 20 21 22 .028 812 2.452 407.8 12.80 : .025 640 1.945 514.2 16.14 ; 23 .0226 511 1.542 648.4 20 36 : .020 404 1.223 817.7 25 67 24 25 28 29 30 31 , 32 .0179 .0159 .0142 .0126 .0113 .010 .0089 .0080 320 253 202 159 128 too >9.2 64.0 , .9699 -7692 .6100 .4837 .3836 .3042 .2413 .1913 1031. 1300. 1639. 2067 2607. 3287. 4145. 5227. 32.37 40.81 51.47 64 90 81 83 103.2 130.1 164.1 ` ' 26 2S 29 30 31 52 33 34 36 i 37 ! 38 ! 39 ; .OO't .0063 .0056 00i0 .004 ' .0040 .0035 .0051 j 1 j 504 39.7 31 4 25 0 20 2 16.0 12.2 9.61 ' ' ' .1517 .1203 .09542 .07568 .06001 04759 .03774 .02993 6591. 8310. 10480. 13210 16660 21010. 26500. 33410. 206.9 260 9 329.0 414.8 525-1 659.6 S31.8 1049. i ' 34 35 56 37 38 39 40 42 RBB 00513 RETURNABLE REEL DATA a REEL DIMENSIONS -- INCHES Flange (A) ..........................................................................................
