Abstract
A multi-wire stranded conductor is formed of a bare wire central core. An intermediate SZ stranded wire is wound on the core, while an outer layer is helically wound on the intermediate SZ wound layer. The intermediate and outer layers assure that the composite conductor maintains a substantially circular cross-section while the helical outer layer also assures the mechanical integrity of the intermediate SZ layer.
