Title:
TWISTED WIRE CONDUCTOR, COVERED ELECTRICAL WIRE, AND METHOD FOR MANUFACTURING TWISTED WIRE CONDUCTOR
Document Type and Number:
WIPO Patent Application WO/2014/112174
Kind Code:
A1
Abstract:
The purpose of the present invention is to improve durability when subjected to bending and stability of shape of a covered electrical wire in which a twisted wire conductor is covered with an insulator. In order to achieve this purpose, the twisted wire conductor has multiple conductor strands twisted together in multiple layers, at least two layers adjacent to each other among the layers having the same twisting direction and having different twisting angles. By this means, contact of strands between adjacent layers is reduced, and entry of strands in outer layers into the gaps between adjacent strands in inner layers is suppressed, whereby durability when subjected to bending and stability of shape of the twisted conductors can be improved. Therefore, durability when subjected to bending and stability of shape of a covered electrical wire in which a twisted wire conductor is covered with an insulator can be improved.
