Document Type and Number:
WIPO Patent Application WO/2023/228468
Kind Code:
A1
Abstract:
This twisted wire is obtained by twisting a plurality of sub-twisted wires together. Each of the sub-twisted wires has the same structure in which a plurality of strands of which the cross-sectional shapes perpendicular to the longitudinal direction are circles of the same diameter, are twisted together. The strands include a steel core wire, and a copper or copper alloy cover layer covering the surface of the core wire. The twist pitch of the sub-twisted wires is at least 40 times the diameter of the circumscribed circle of the sub-twisted wires. The twist pitch of the twisted wires is 5-20 times the diameter of the circumscribed circle of the twisted wires.
