Abstract
A stranded cable that includes a plurality of brittle load bearing wires and a means for maintaining the stranded arrangement of the brittle wires. Because the load bearing wires are brittle, they cannot be sufficiently deformed during conventional cable stranding processes in such a way as to maintain their helical arrangement. Therefore, the means for maintaining the helical arrangement of the stranded wires allows the stranded cable to be conveniently provided as an intermediate article or as a final article. When used as an intermediate article, it may be later incorporated into a final article such as overhead power transmission cables. The maintaining means may be a tape, an adhesive tape, or a binder applied to the stranded wires.
