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

ABSTRACT
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. Compact ACSR covered by this specification has five types of steel core wire which are designated by ACSR/GA/COMP, ACSR/GB/COMP, ACSR/GC/COMP, ACSR/AZ/COMP, ACSR/AW/COMP. Electric-butt welds, electric-butt, cold-upset welds, or cold-pressure welds in the individual round-drawn or shaped aluminum wires shall be made during the stranding process. The preferred lay of the aluminum wires of aluminum conductors, steel-reinforced, having a single wire steel core and one layer of aluminum wires shall be 14 times the outside diameter of the conductor but the lay shall be not less than 13 nor more than 16 times that diameter. The diameter of the steel core wire, the number of aluminum wires, the aluminum cross-sectional area, the diameter and weight of the compact round concentric-lay-stranded aluminum conductors, steel-reinforced, shall conform to the construction requirements. The rated strength of a completed conductor shall be taken as the aggregate strength of the aluminum and steel components, and shall be calculated according to the prescribed computation. The mass and electrical resistance of a unit length of stranded conductor shall be a function of the length of lay. Tests for mechanical and electrical properties of aluminum wires composing the conductors shall be made before stranding.
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).
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.
