Abstract
Lightweight composite electrical conductors made up of a plastic matrix or plastic core, a plurality of electrical conductors either embedded within the plastic matrix or circumferentially surrounding an outer surface of the plastic core, and at least one insulating layer, 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.
Claims28
A lightweight composite electrical conductor that consists essentially of:
- (a) a plastic matrix or plastic core;
- (b) a plurality of electrical conductors either (i) embedded and fixed in place within the plastic matrix or (ii) circumferentially surrounding an outer surface of the plastic core, wherein at least some of the electrical conductors circumferentially surround and touch the outer surface of 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 and touches an outer surface of the plastic core;
- and
- (c) at least one extruded, crosslinked ethylene tetrafluoroethylene copolymer insulating layer, wherein one insulating layer circumferentially surrounds and touches 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 and touches an outer surface of the plastic core;
- and
- (c) at least one extruded, crosslinked ethylene tetrafluoroethylene copolymer insulating layer, wherein one insulating layer circumferentially surrounds and touches 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 consist essentially of:
- (a) a plastic matrix or plastic core;
- (b) a plurality of electrical conductors either (i) embedded and fixed in place within the plastic matrix or (ii) circumferentially surrounding an outer surface of the plastic core, wherein at least some of the electrical conductors circumferentially surround and touch the outer surface of the plastic core;
- and
- (c) at least one insulating layer circumferentially surrounding the plastic matrix or the plurality of electrical conductors.
