| 1. A process of producing an overhead transmission conductor, which consists of:
(a) hot-rolling a continuous cast alloy bar of AA 1350 aluminum alloy having a maximum copper content of 0.05 wt. % to form
a rod;
(b) then directly hot-coiling the rod at a temperature in a range of about 300 to 400° C. and allowing the coiled rod to cool
to ambient temperature 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 said rod to an annealing treatment, drawing said rod into wire; and
(d) stranding said wire into cable to form said overhead transmission conductor.
