    摘要： An insulating composition for an electric power cable, and an electric power cable comprising a conductor surrounded by an inner semiconducting layer, an insulating layer, and an outer semiconducting layer, where the insulating layer consists of said insulating composition, are disclosed. The insulating composition is characterised in that the ethylene polymer is a multimodal ethylene copolymer obtained by coordination catalysed polymerisation of ethylene and at least one other alpha-olefin in at least one stage, said multimodal ethylene copolymer having a density of 0.890-0.940 g/cm3, an MFR¿2? of 0.1-10 g/10 min, an MWD of 3.5-8, a melting temperature of at most 125 °C, and a comonomer distribution as measured by TREF, such that the fraction of copolymer eluted at a temperature higher than 90 °C does not exceed 10 % by weight, and said multimodal ethylene compolymer including an ethylene copolymer fraction selected from (a) a low molecular weight ethylene copolymer having a density of 0.900-0.950 g/cm?3¿ and an MFR¿2? of 25-500 g/10 min, and (b) a high molecular weight ethylene copolymer having a density of 0.870-0.940 g/cm3 and an MFR2 of 0.01-3 g/10 min.
