Abstract
The present invention relates to wet design high voltage (HV) power cables comprising a cable core, which cable core comprises an electrical conductor being surrounded by an inner semiconductive layer, an insulation layer and optionally an outer semiconductive layer in that order. Further, the present invention relates to a method of manufacturing a wet design HV power cable. Moreover, the present invention relates to the use of the wet design HV power cable.
Claims15
A wet design HV power cable comprising a cable core (1), which cable core (1) comprises an electrical conductor (2) being surrounded by an inner semiconductive layer (3), an insulation layer (4) and optionally an outer semiconductive layer (5) in that order;
- wherein
- the inner semiconductive layer (3) comprises acetylene black in a polymer matrix of the inner semiconductive layer;
- and
- the insulation layer (4) comprises a polymer,
- wherein the polymer is a non-blended polymer consisting of an XLPE homopolymer, and
- wherein the polymer matrix of the inner semiconductive layer comprises a copolymer made of an olefin comonomer and a polar comonomer.
A wet design HV power cable comprising a cable core (1), which cable core (1) comprises an electrical conductor (2) being surrounded by an inner semiconductive layer (3), an insulation layer (4) and optionally an outer semiconductive layer (5) in that order;
- wherein
- the inner semiconductive layer (3) comprises acetylene black in a polymer matrix of the inner semiconductive layer;
- and
- the insulation layer (4) comprises a polymer blend comprising at least a first polymer and a second polymer, wherein the first polymer consists of an XLPE homopolymer, and the second polymer consists of a copolymer being devoid of polar comonomers.
