Abstract: A joint (300) for joining a first electric cable (100) and a second electric cable (200), each cable (100; 200) having an electric conductor, an insulation system surrounding the electric conductor, and a water barrier (130;230) surrounding the insulation system. The insulation system has an inner semiconducting layer, an insulating layer and an outer semiconducting layer, where the joint has an electrical conductor joint electrically connecting end sections of the two electrical conductors. An insulation system joint has an inner layer made of a first polymeric semiconducting material surrounding the electric conductor joint, an intermediate insulating layer made of a polymeric insulating material, covering an external surface of the inner semiconducting layer, an outer layer made of a second polymeric semiconducting material, covering an external surface of the insulating layer; and a water barrier layer surrounding the insulation system joint, wherein the water barrier layer is made of pre-formed water barrier elements (140a; 140b; 240a; 240b).

Abstract: A dynamic power cable or cables for submarine applications, wherein the dynamic power cable has at least one fibre reinforced thermoplastic composite sheath radially around a water barrier sheath providing reduced buckling of the water barrier sheath. The at least one fibre reinforced thermoplastic composite sheath has wound fibres embedded in a thermoplastic polymer.
