MULTI-WIRE SZ AND HELICAL STRANDED CONDUCTOR AND METHOD OF FORMING SAME

摘要

A multi-wire stranded conductor (10) is formed of a bare wire central core (12), an intermediate SZ stranded wire layer (14) wound on the core, and an outer layer (L2) helically wound on the intermediate SZ layer. The intermediate and outer layers assure that the multi-wire stranded conductor (10) maintains a substantially circular cross-section whi le the helical outer layer assures the mechanical integrity of the intermediate SZ layer.
