A manufacturing method is provided to form an overhead transmission cable having an elongated stranded steel core, and at least one layer of conductor wires generally encircling the stranded steel core. Each conductor wire includes a circumferentially extending, metallurgically bonded aluminum outer layer of at least 99. 5 percent pure aluminum and having an IACS conductivity of at least 20. 3 percent. In one embodiment, the steel conductors include a generally circular cross-section and an aluminum outer layer metallurgically bonded thereto, with the thickness of the aluminum outer layer being at least 10 percent of the overall radial dimension of the conductor.
