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. 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. |
