Abstract

A cable having one or more conductors surrounded by at least an inner semiconductive layer, an insulation layer and an outer semiconductive layer, in that order. The insulation layer has at least 90 wt % of a polymer composition, said polymer composition having 80.0 to 99.9 wt % of an LDPE homopolymer or copolymer; and 0.1 to 20.0 wt % of: an ultra-high molecular weight polyethylene having a Mw of at least 1,000,000; or a single site catalysed medium density polyethylene (MDPE) having a density of 925 to 940 kg/m3 or a single site catalysed linear low density polyethylene (LLDPE) having a density of 910 to 925 kg/m3.
