Abstract

An environmentally desirable composition with sufficient electrical stability to be suitable for making the dielectric (insulation) of a medium-voltage cable comprises, in parts by weight polymer base, of which at least 50 parts are ethylene copolymer rubber and the balance, if any, polyethylene 100, mineral filler of which at least half is calcined clay 40-120, surface treatment agent for the filler 1-6, zinc oxide 10-30, lead compounds not to exceed 1 calculated as element and appropriate amounts of conventional ingredients comprising an antioxidant, a curing system and a processing aid.
