Abstract

This specification covers concentric-lay-stranded conductors made from round-alloy 6201-T81 hard:solution heat treated, cold worked, and then artificially aged wire and round zinc-coated, Zn-5Al-MM coated, aluminum-coated, or aluminum-clad steel core wire for use as overhead electric conductors. Cold-pressure welds, electric-butt welds, and electric-butt, cold-upset welds in the finished individual aluminum alloy wires composing the conductor may be made during the stranding process. The direction of lay of the outside layer of aluminum-alloy wires shall be right-hand. The direction of lay of the aluminum alloy and steel wires shall be reversed in successive layers. The rated strength of a conductor shall be taken as the sum of the strengths of the aluminum alloy and steel components. The mass and electrical resistance of a unit length of stranded conductor shall be calculated. The ares of cross section may be determined by calculations from diameter measurements of the component aluminum wires at any point when measured perpendicularly to their axes.
