    1. 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 or ACSR/GA2ACSR using Class A zinc-coated steel wire,

    1.2.2 ACSR/GC or ACSR/GC2ACSR using Class C zinc-coated steel wire,

    1.2.3 ACSR/MA or ACSR/MA2ACSR using Class A Zn-5A1-MM coated steel wire,

    1.2.4 ACSR/HS or ACSR/GA3ACSR using Class A zinc-coated high-strength steel wires,

    1.2.5 ACSR/MS or ACSR/MA3ACSR using Class A Zn-5A1-MM coated high-strength steel wires,

    1.2.6 ACSR/GA4ACSR using Class A zinc-coated extra-high-strength steel wires,

    1.2.7 ACSR/MA4ACSR using Class A Zn-5A1-MM coated extra-high-strength steel wires,

    1.2.8 ACSR/GA5ACSR using Class A zinc-coated ultra-high-strength steel wires,

    1.2.9 ACSR/MA5ACSR using Class A Zn-5Al-MM coated ultra-high-strength steel wires.

    1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
