LIGHTWEIGHT POWER CABLE COMPRISING A SEMICONDUCTIVE LAYER WITH REDUCED PROTRUSION SIZE, AND AN INSULATING LAYER WITH HIGH DIELECTRIC BREAKDOWN STRENGTH BY USING A SEMICONDUCTIVE COMPOSITION AND INSULATIVE COMPOSITION

摘要

PURPOSE: A lightweight powder cable is provided to have excellent physical properties like volume ratio resistance, hot set, tensile strength, elongation, etc which are required for power cable, and to have excellent dielectric breakdown strength.;CONSTITUTION: A lightweight powder cable comprises a conductor, an inner semiconductive layer, an insulating layer surrounding the inner semiconductive layer, and an outer semiconductive layer surrounding the insulating layer. The inner semiconductive layer or the outer semiconductive layer is formed by a semiconductive composition. The semiconductive composition comprises carbon nanotubes, carbon black, graphene, carbon nanotube-graphene hybrid composite.;COPYRIGHT KIPO 2012
