ABSTRACT:
Filling compounds for high voltage, electric power transmission cables have been deficient in one characteristic or another, such as incompletely filling voids during manufacture, forming voids when cables are in service, lack of permanent adhesion to cable components to prevent passage of water lengthwise of the cable, and low drip point when cables are at elevated temperatures. This invention is a cable filled with a compound of isobutylene rubber that obtains all of the desirable filler characteristics for a high voltage power transmission cable.
