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 Notes 1 and 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).

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

1.2.2 ACSR/GB/COMP -Compact ACSR using Class B zinc-coated steel wire,

1.2.3 ACSR/GC/COMP -Compact ACSR using Class C zinc-coated steel wire,

1.2.4 ACSR/AZ/COMP -Compact ACSR using aluminum-coated (aluminized) steel wire, and

1.2.5 ACSR/AW/COMP -Compact ACSR using aluminum-clad steel wire.

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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
