Abstract

In a method for manufacturing a stranded conductor for an electric power cable comprising a process for forming insulating films by passing an uninsulated stranded conductor constituted by a plurality of stranded conductive strands through oxidizing liquid, the stranded conductor passing through the liquid is curved at an angle of 3.degree. to 10.degree. in a predetermined path to form gaps between the strands, and the oxidizing liquid is caused to penetrate between the strands through the gaps to form oxide films on the surfaces of the strands.
