Using new technology to improved reliability of an industrial cable distribution system

The service history of medium-voltage power cables on the US plant sites of a major industrial manufacturer from 1961 through 1990 is summarized. In past years this company tended to be reactive, using specifications, diagnostic testing, and maintenance practices to manage the reliability of their cable distribution systems. Several new technologies in insulation systems, terminations, splices, and installation techniques, introduced in recent years, have allowed a more proactive stance to be taken. In addition, because of some specific failure problems, a highly qualified in-house team has been formed to evaluate existing and future technologies and new insulation materials to assure a reliable cable system. It is concluded that the combination of materials and engineering technology has brought a new dimension to the process of installing and maintaining reliable cable systems.<
