Title:
INSULATED DIVIDED CONDUCTOR CABLE HAVING BRIDGED POLYETHYLENE INSULATED WIRES
Document Type and Number:
Japanese Patent JPH05274926
Kind Code:
A
Abstract:

PURPOSE: To ensure easy manufacture and improve such capability as preventing the occurrence of skin separation by using a polyamide enameled wire as a conductor wire, and specifying the skin thickness of the enameled wire.

CONSTITUTION: The divided conductor of a CV power cable comprises six segments 1 and each conductor wire 2 constituting each segment 1 has a coaxial multilayer structure. For the surface of the wire 2, an amide enameled wire 4 covered with a polyamide insulation skin 3 is used, and the thickness of the skin is taken at a value between 10 and 20μm. The wire 4 has excellent characteristics in terms of heat resistance, chemical resistance, oil resistance, abrasion resistance, hydrolysis resistance or the like. Thus, the separation of the skin does not occur even in a wire twisting work similar to a conventional case, so far as the skin thickness between 10 and 20μm is maintained. Also, the wire 4 is not affected by high temperature (approximately 210°C) at the time of extruding and bridging an insulator, and the occurrence of decomposition, adhesion or the like due to a bridging agent and a residue after reaction can be prevented.
