Abstract: Use of a cable, e.g. to carry power, in a salt water environment, e.g. in the sea or under the sea; said cable comprising a conductor which is surrounded by at least an inner semiconductive layer, an insulation layer and an outer semi conductive layer in that order; wherein said insulation layer comprises (i) at least 60 wt % of a low density polyethylene homo or low density polyethylene copolymer with at least one polyunsaturated comonomer and optionally one or more further comonomers; and, (ii) 10 to 35 wt % of a low density polyethylene copolymer of ethylene and at least one polar comonomer selected from the group consisting of an alkyl acrylate, an alkyl methacrylate or vinyl acetate.

Abstract: The present invention relates to a process for manufacturing a power cable, which power cable comprises at least one core comprising a conductor and an expanded and crosslinked insulation layer surrounding said conductor, wherein said process comprises the steps a) to d): a) providing a blend of: a polymer composition comprising a polyolefin material, which polyolefin material bears silane moieties; a catalyst and a foaming system, wherein the provided blend will comprise at least 0.1% by weight of a foaming agent, with respect to the total weight of the polyolefin material; b) extruding a blend, as described in step a), on the conductor to form an insulation layer; c) foaming the insulation layer; and d) crosslinking the insulation layer; a power cable which is obtainable by the process, and use of the power cable.
