Conductor for an electrical power cable and a method for manufacturing the same

Abstract

In a method for manufacturing a stranded conductor for an electrical power cable comprising a process for forming cupric oxide films of from 0.3 .mu.m to 3 .mu.m in thickness by passing an uninsulated stranded conductor constituted by a plurality of stranded copper strands through oxidizing liquid, the stranded conductor passing through the liquid is curved in a wave to form gaps between the strands, and the oxidizing liquid is caused to penetrate between the strands through the gaps to form cupric oxide films of from 0.3 .mu.m to 3 .mu.m in thickness on the surfaces of the strands. Also disclosed is a stranded conductor for an electrical power cable constituted by a plurality of stranded copper strands, at least one of the copper strands being covered with a cupric oxide film free from exfoliation.
