1. Scope

1.1 This specification covers compact round concentric-lay-stranded conductors made from aluminum 1350-H19 (extra hard) wires and round zinc-coated, aluminum-coated, or aluminum-clad steel core wires usually used in overhead lines. These conductors shall be constructed with one steel core wire surrounded by one or more layers of helically-laid compacted or otherwise shaped aluminum wires (Explanatory Note 1 and Note 2).

1.2 Compact ACSR covered by this specification has five types of steel core wire which are designated by abbreviations as follows (Explanatory Note 2 and Note 7).

1.2.1 ACSR/GA2/COMP—Compact ACSR using Class A zinc-coated steel wire,

1.2.2 ACSR/GC2/COMP—Compact ACSR using Class C zinc-coated steel wire,

1.2.3 ACSR/AW2/COMP—Compact ACSR using aluminum-clad steel wire, AW2 (Normal Strength).

1.2.4 ACSR/AW3/COMP—Compact ACSR using aluminum-clad steel wire, AW3 (High Strength).

1.3 The SI values of density and resistivity are to be regarded as standard. For all other properties the inch-pound values are to be regarded as standard and the SI units may be approximate.

Note 1: Prior to 1975, aluminum 1350 was designated as EC aluminum.

Note 2: The aluminum and temper designations conform to ANSI H35.1. Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E527.
