摘要: The present invention is a moisture impervious electrical power cable and conduit system. comprises impervious, electrically conducting inner layer, which acts as concentric neutral for the cable, an outer layer of insulating or semiconductive polymeric material. insulated central core conductive material surrounded with material, placed longitudinally inside in sufficient contact to allow it act neutral. article this may then be ground should fail, said withdrawn from new drawn through conduit, thereby eliminating necessity disinterring replacing entire line
