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.
Claims17
A multi-wire stranded conductor comprising a bare wire central core;
- at least one intermediate SZ layer of bare wire wound on said core;
- and an outer layer of bare wire helically wound on said at least one SZ wound layer, whereby said intermediate and outer layers assure that a composite conductor maintains a substantially circular outer cross-section while said helical outer layer assures the mechanical integrity of said at least one SZ intermediate layer.
A multi-stranded conductor comprising a central core;
- and n layers wound on said core, at least one intermediate layer l to n-1 being SZ wound layers and a radially outermost layer n being helically wound about said intermediate layers, said at least one intermediate and outer layer assuring that a composite conductor maintains a substantially circular outer cross-section while said helical outer layer assures the mechanical integrity of said at least one SZ intermediate layer and wherein n is an integer >1.
A multi-wire stranded conductor comprising a bare wire central core;
- at least one intermediate SZ layer of bare wire wound on said core;
- and an outer layer of bare wire helically wound on said at least one SZ wound layer, whereby said intermediate and outer layers assure that a composite conductor maintains a substantially circular outer cross-section while said helical outer layer assures the mechanical integrity of said at least one SZ intermediate layer, wherein said core, intermediate and outer layers are all formed of wire strands having circular cross sections, and wherein all said strands have the same diameter.
A multi-stranded conductor comprising a central core;
- and n layers wound on said core, at least one intermediate layer l to n-1 being SZ wound layers and a radially outermost layer n being helically wound about said intermediate layers, said at least one intermediate and outer layer assuring that a composite conductor maintains a substantially circular outer cross-section while said helical outer layer assures the mechanical integrity of said at least one SZ intermediate layer, wherein said core, intermediate and outer layers are all formed of wire strands having circular cross sections, and wherein all said strands have the same diameter.
