Designation: B 232/B 232M – 99 Standard Specification for Concentric-Lay-Stranded Aluminum Conductors, CoatedSteel Reinforced (ACSR)1 This standard is issued under the fixed designation B 232/B 232M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision A number in parentheses indicates the year of last reapproval A superscript epsilon (e) indicates an editorial change since the last revision or reapproval Scope 1.1 This specification covers concentric-lay-stranded conductors made from round aluminum 1350-H19 (extra hard) wires and round, coated steel core wire(s) for use as overhead electrical conductors (Explanatory Note and Explanatory Note 2) 1.2 ACSR covered by this specification has nine types of coated steel core wire which are designated by abbreviations as follows (Explanatory Note 2): 1.2.1 ACSR/GA-ACSR using Class A zinc-coated steel wire, 1.2.2 ACSR/GB-ACSR using Class B zinc-coated steel wire, 1.2.3 ACSR/GC-ACSR using Class C zinc-coated steel wire, 1.2.4 ACSR/MA-ACSR using Class A Zn-5A1-MM coated steel wire, 1.2.5 ACSR/MB-ACSR using Class B Zn-5A1-MM coated steel wire, 1.2.6 ACSR/MC-ACSR using Class C Zn-5A1-MM coated steel wire, 1.2.7 ACSR/HS-ACSR using Class A zinc-coated highstrength steel wires, 1.2.8 ACSR/MS-ACSR using Class A Zn-5A1-MM coated high-strength steel wires, and 1.2.9 ACSR/AZ-ACSR using aluminum-coated (aluminized) steel wire 1.3 The values stated in inch-pound or SI units are to be regarded separately as standard The values in each system are not exact equivalents; therefore, each system shall be used independently of the other Combining values from the two systems may result in nonconformance with the specification 1.3.1 For density, resistivity and temperature, the values stated in SI units are to be regarded as standard Referenced Documents 2.1 The following documents of the issue in effect on date of material

Reels are not designed to withstand the forces required for braking during tension stringing operations C Pay-off equipment for reels NR 48.28 and smaller should be a minimum of in (50 mm) wider than the nominal outside reel width to provide for extension of bolts and for possible flange distortion For reels NR 60.28 and larger, either wood or metal, pay-off equipment should be not less than in (100 mm) wider than the reel width D Hub reinforcements will be provided for reel NR 60.28 E Reels RM 66.32 and RM 68.38 have flat rims F Reels RMT 84.36, RMT 84.45, RMT 90.45, and RMT 96.60 have 3-in (76 mm) I-beam tires Reels with similar dimensions except without I-beam tires are sometimes used B 17.4 The net mass, length, size, kind of conductors, stranding, type of coating, class of zinc or Zn-5A1-MM coating (if used), and any other necessary identification shall be marked on a tag attached to the end of the conductor inside the package This same information, together with the purchase order number, the manufacturer’s serial number (if any), and all shipping marks and other information required by the purchaser shall appear on the outside of each package calculations and is based upon the standard SI density with the conversion rounded to the nearest 0.0005 lb/in.3 NOTE 6—The increment of mass or electrical resistance of a completed concentric-lay-stranded conductor (k) in percent is: k 100 ~m 1! where m is the stranding factor, and also the ratio of the mass or electrical resistance of a unit length of stranded conductor to that of a solid conductor of the same cross-sectional area or of a stranded conductor with infinite length of lay, that is, all wires parallel to the conductor axis The stranding factor m for the completed stranded conductor is the numerical average of the stranding factors for each of the individual wires in the conductor, including the straight core wire, if any (for which the stranding factor is unity) The stranding factor (mind) for any given wire in a concentric-lay-stranded conductor is: 18 Keywords 18.1 aluminum conductor; concentric-lay-stranded aluminum conductor; electrical conductors; electrical conductors, aluminum; steel-reinforced conductors; stranded aluminum conductors where n EXPLANATORY NOTES mind =1 ~9.8696/n2! length of lay diameter of helical path of the wire The derivation of the above is given in NBS Handbook, 100 Copper Wire Tables The factors k and m are to be determined separately for the zinc-coated or aluminum-coated steel (Section 8) NOTE 7—Wires unlaid from conductors may have different physical properties from those of the wire prior to stranding because of the deformation caused by stranding and straightening for test If tests on galvanized or aluminum-coated steel wires are to be made after stranding, the purchaser and the manufacturer at the time of placing the order should agree on the properties to be met NOTE 8—To test ACSR conductors for breaking strength successfully as a unit requires special devices for gripping the ends of the aluminum and steel wires without causing damage that may result in failure below the actual strength of the conductor Various special dead-end devices are available such as compression sleeves, split sleeves, and preformed grips, but ordinary jaws or clamping devices usually are not suitable NOTE 1—In this specification only concentric-lay-stranded aluminum conductors, steel-reinforced, are specifically designated Conductor constructions not included in this specification should be agreed upon between the manufacturer and the purchaser when placing the order NOTE 2—For definitions of terms relating to conductors, refer to Terminology B 354 NOTE 3—The behavior of properly spaced wire joints in stranded conductors is related to both their tensile strength and elongation Because of its higher elongation properties, the lower-strength electric-butt weld gives equivalent overall performance to that of a cold-pressure weld or an electric-butt, cold-upset weld in stranded conductors NOTE 4—The preferred ratio of the lay with respect to the outside diameter of a layer of wires varies for different layers and for different diameters of the conductors, being larger for the inside layers than for the outside layer, and larger for conductors of small diameter than for those of large diameter NOTE 5—This density is based upon aluminum of 99.50 % purity The inch-pound density of the aluminum wires is used for mass per unit length 15 B 232/B 232M allow a permissible variation in length of 65 % for sizes larger than No AWG [40 mm2] and a tolerance of 610 % on sizes No AWG [40 mm2] and smaller It is also common practice to allow an amount not exceeding 10 % of the total mass of any one order to be shipped in random lengths with no piece shorter than 50 % of the standard length ordered NOTE 9—For the convenience of the users of this specification, Tables and have been prepared giving recommended shipping lengths for the standard sizes of ACSR referred to in Tables and respectively Values of net mass in this table are rounded to the nearest ten pound increment
