A power cable comprising: a power core including: a conductor, an insulation system including an inner semiconducting layer arranged around the conductor, an insulation layer arranged around the inner semiconducting layer, and an outer semiconducting layer arranged around the insulation layer, a first metallic water blocking layer arranged concentrically with and around the outer semiconducting layer, a semiconducting polymer layer arranged concentrically with and around the first metallic water blocking layer, and a second metallic water blocking layer arranged concentrically with and around the semiconducting polymer layer; and an outer sheath arranged around the second metallic water blocking layer.

Power cable with multiple water barriers

A static AC submarine power cable configured for at least 72 kV operation including: a power core including: a conductor, an insulation system surrounding the conductor, and a smooth metallic water-blocking sheath surrounding the insulation system, wherein the metallic water-blocking sheath includes stainless steel.

AC submarine power cable with reduced losses

A rigid joint assembly for jointing two cables; the assembly includes outer cable entry parts outside a water-tight casing assembly. A first and second cable insulation system deformation preventing devices are provided, each including a rigid pipe, which surrounds a respective first or second cable core end section, and a bedding material layer, which extends at least partially along a length of an inner surface of the respective rigid pipe. The assembly further includes first and second grooved pipes of elastic material having a plurality of grooves on the side facing the cable, each grooved pipe surrounding the respective first or second cable core end section at a respective inner cable entry part inside the water-tight casing assembly
