Reduced Adhesion Strippable Insulation Shields Using Nano-Scale Mineral Fillers for TRXLPE Insulated Medium Voltage Power Cables

摘要

Semiconducting insulation shield compounds with reduced adhesion to tree retardant cross-linked polyethylene (TRXLPE) are presented. Through a combination of additives comprising 5% by weight of the formulation or less, adhesion force can be reduced by 40% or more without compromising other critical properties such as volume resistivity, cure kinetics, and physical characteristics including tear strength.
