Abstract
Composite electrical conductors having a desirable combination of excellent tensile strength, acceptable levels of current carrying capacity, reduced weight and preferably high temperature resistance, as well as, cables incorporating one or more of these conductors, are provided. The inventive composite conductors and cables are particularly useful for automotive and aircraft wire and cable.
Claims26
A lightweight composite electrical conductor that comprises:
- (a) a plastic matrix or plastic core;
- (b) a plurality of electrical conductors either embedded within the plastic matrix or circumferentially surrounding the plastic core;
- and
- (c) at least one insulating layer circumferentially surrounding the plastic matrix or the plurality of electrical conductors.
A lightweight composite electrical conductor that comprises:
- (a) a solid or substantially solid plastic core prepared from one or more polyether ether ketone resins;
- (b) a plurality of stranded tin-plated copper wires contained in a single layer that circumferentially surrounds the plastic core;
- and
- (c) at least one extruded, crosslinked ethylene tetrafluoroethylene copolymer insulating layer circumferentially surrounding the layer formed by the stranded tin-plated copper wires.
A lightweight composite electrical conductor that comprises:
- (a) a hollow tubular plastic core prepared from one or more polyether ether ketone resins;
- (b) a plurality of stranded tin-plated copper wires contained in a single layer that circumferentially surrounds the plastic core;
- and
- (c) at least one extruded, crosslinked ethylene tetrafluoroethylene copolymer insulating layer circumferentially surrounding the layer formed by the stranded tin-plated copper wires.
A cable incorporating one or more lightweight composite electrical conductors, wherein the one or more lightweight composite electrical conductors each comprise:
- (a) a plastic matrix or plastic core;
- (b) a plurality of electrical conductors either embedded within the plastic matrix or circumferentially surrounding the plastic core;
- and
- (c) at least one insulating layer circumferentially surrounding the plastic matrix or the plurality of electrical conductors.
