A low adhesion semiconductive dielectric shield for use with cross-linked polyethylene, ethylene-propylene-diene rubber (EPDM rubber) insulation. The dielectric shield comprises a base polymer which is a copolymer of ethylene with a mono-unsaturated ester; a conductive filler in an amount sufficient t o give an electrical resistivity below 550 ohms-meter and as an adhesion adjusting device an ethylene vinyl acetate, ethylene alkyl methacrylate copolymer having a molecular weight above 20,000 daltons and a polydispersit y greater than 2.5 wherein the adhesion between the insulation and the semiconductive shield is between about 3-26 lbs per 1/2 inch.
