ASTM B232/B232M-01
(Specification)Standard Specification for Concentric-Lay-Stranded Aluminum Conductors, Coated-Steel Reinforced (ACSR)
Standard Specification for Concentric-Lay-Stranded Aluminum Conductors, Coated-Steel Reinforced (ACSR)
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 1 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 high-strength 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.
Note 1—The aluminum and temper designations conform to ANSI Standard H35.1/H35.1M; Aluminum 1350 corresponds to UNS No. A91350 in accordance with Practice E527.
