The present invention concerns a power cable, comprising a tension member (1), placed in the centre of said power cable; a first insulation layer (3), the tension member (1) being embedded in the first insulation layer (3); and an outer protective sheath (9); wherein said power cable further comprises one or more first aluminum conductors (4), embedded within the first insulation layer (3). The present invention also concerns a process for producing the inventive power cable, the process comprising the step of extruding a first polymeric insulation layer (3) onto the tension member (1) and the one or more conductors (4) in one single step. Finally, the present invention concerns the use of the inventive power cable, in medium-voltage to high-voltage subsea applications, such as an offshore windmill cable infrastructure or driving of subsea pumps.
A process for producing a power cable comprising extruding a first insulation layer onto at least one tension member and one or more first electrical conductors in a single step such that the at least one tension member is positioned in proximity to a center of the first insulation layer and surrounded by and in contact with the first insulation layer, and such that the one or more first electrical conductors are spaced from the tension member and surrounded by and in contact with the first insulation layer.
A process for producing a power cable comprising:
A process for producing a multi-core power cable comprising:
