Abstract:
An alternating current (AC) power cable includes a conductor surrounded by at least an inner semiconductive layer including a first semiconductive composition, an insulation layer including a polymer composition, an outer semiconductive layer including a second semiconductive composition, and optionally a jacketing layer including a jacketing composition, in that order. The polymer composition of the insulation layer includes an unsaturated low density polyethylene (LDPE) copolymer of ethylene with one or more polyunsaturated comonomers and a crosslinking agent. The polymer composition of the insulation layer has a dielectric loss expressed as tan δ (50 Hz) of 12.0×10 −4  or less, when measured at 25 kV/mm and 130° C. according to “Test for Tan δ measurements on 10 kV cables”.

Claim (Index 1):
An alternating current (AC) power cable, comprising a conductor surrounded by at least an inner semiconductive layer comprising a first semiconductive composition, an insulation layer comprising a polymer composition, an outer semiconductive layer comprising a second semiconductive composition and optionally a jacketing layer comprising a jacketing composition, in that order, wherein\n the polymer composition of the insulation layer comprises a polyolefin and a crosslinking agent, wherein the polyolefin is an unsaturated low density polyethylene (LDPE) copolymer of ethylene with one or more polyunsaturated comonomers, and wherein the polymer composition of the insulation layer has a dielectric loss expressed as tan \u03b4 (50 Hz) of 12.0\u00d710 \u22124  or less, when measured at 25 kV/mm and 130\u00b0 C. according to \u201cTest for Tan \u03b4 measurements on 10 kV cables\u201d as described in the description part under \u201cDetermination methods\u201d; and wherein the polyolefin is obtainable by a high pressure process comprising: (a) compressing one or more monomer(s) under pressure in a compressor, using a compressor lubricant comprising a mineral oil for lubrication, (b) polymerizing a monomer optionally together with one or more comonomer(s) in a polymerization zone, and (c) separating the obtained polyolefin from the unreacted products and recovering the separated polyolefin in a recovery zone.
