ABSTRACT:
A process of producing an overhead transmission conductor. The process comprises: (a) continuously hot rolling a bar of AA 1350 aluminum or a similar aluminum alloy to form a rod; (b) hot-coiling the rod at a temperature preferably in a range of about 300 to 400° C. to provide an aluminum electrical conductor rod having an electrical conductivity in a range of 61.8 to 64.0% IACS and a tensile strength in a range of 8,500 to 14,000 psi; (c) without subjecting the rod to an annealing treatment, drawing the rod into wire: and (d) stranding the wire into cable to form the overhead transmission conductor. The invention also relates to an ACSS conductor produced by the process.
