Standard Specification for Compact Round Concentric-Lay-Stranded Aluminum Conductors, Steel-Reinforced (ACSR/COMP)
 N B401

Annotation

This specification covers compact round concentric-laystranded 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).

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).

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

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

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

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

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.
