Abstract
The present invention features a high-voltage, high-temperature cable article for use with electric motors, coils, transformers, generators and power supplies. The cable article has a conductive core member overlaid with an intermediate, semiconductive layer and an outer, insulative jacket layer. The intermediate, semiconductive layer can be a carbon-impregnated polymer such as a carbon-impregnated polyethylene; a carbon-impregnated, ethylene-propylene-diene terpolymer (EPDM); semiconductive nylon tape; semiconductive PTFE (polytetrafluoroethylene) tape; semiconductive fabric tape; or a semiconductive extruded fluorocarbon. The temperature rating of the cable article is at least approximately 150° C.; the voltage rating can be in a range of approximately between 1,000 to 15,000 volts. The wall thickness of the semiconductive layer can range from approximately 2 to 20 mils. The outer, insulative jacket layer can be a cross-linked polyolefin, an elastomeric or a thermoplastic elastomer material. The conductive core can be solid or stranded wire.
