Scope

1.1 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). 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. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
