COMPOSITE STRANDED WIRE CONDUCTOR AND BENDING RESISTANT ELECTRIC WIRE

A composite stranded wire conductor includes a core bunched strand wire, first bunched strand wires mainly wound at a first main twist pitch around the core bunched strand wire, and second bunched strand wires wound at a second main twist pitch around first bunched strand wires. In the core bunched...

More Information
Summary:A composite stranded wire conductor includes a core bunched strand wire, first bunched strand wires mainly wound at a first main twist pitch around the core bunched strand wire, and second bunched strand wires wound at a second main twist pitch around first bunched strand wires. In the core bunched strand wire, metal wires are primary twisted in a first direction. In each of the first bunched strand wires, metal wires are primary twisted in a second direction opposite to the first direction. In each of the second bunched strand wires, metal wires are primary twisted in the first direction. A pitch ratio obtained by dividing the second main twist pitch by the first main twist pitch is 1.00 or more and 2.44 or less.
