Abstract
An electric cable, has an electrical conductor surrounded by a cured electrically-insulating layer obtained from a curable composition with a polymer matrix, the polymer matrix having one or more polyolefins and a polyvinyl acetal as agent for reducing the formation of water treeing, the quantity of PVA being no more than 10% by weight in the composition.
