Abstract :
The construction of current extruded-dielectric, medium-voltage underground residential distribution (URD) cable is described, and requirements for semiconductive shields are examined. Conductor shields, insulation shields, semiconductive jackets, shields for high-voltage cables, and shields for rubber insulation are included. The composition of carbon black and polymer shields is discussed, and the mechanism of conduction in semiconductive shields are described. The historical development of shields is traced, starting with early types and covering developments in the 1970s, 1980s, and 1990s.<>
