摘要： A power cable having: a conductor and having: a first conductor section including an elongated first central element made of a first metal and a first outer metal structure made of a second metal surrounding the first central element, a second conductor section including the second metal, a weld metal located axially between the first conductor section and the second conductor section, wherein the first conductor section has a first axial end section extending to the weld metal, wherein the first axial end section includes: a central axially extending first metal member surrounded by the first outer metal structure, the first metal member including a first axial part made of the first metal and a second axial part made of the second metal, wherein the first axial part has a first end that is welded to the first central element and a second end that is welded to a first end of the second axial part, and wherein the second axial part has a second end, wherein the second end of the second axial part and the first outer metal structure are welded to the second conductor section by means of the weld metal.

摘要： A submarine power cable including a conductor, an insulation system arranged around the conductor, the insulation system including an inner semiconducting layer, an insulation layer arranged around the inner semiconducting layer, and an outer semiconducting layer arranged around the insulation layer, and a polymeric sheath arranged around the insulation system, wherein the first section has a mechanically flexible sheath arranged around the insulation system, wherein the mechanically flexible sheath has a lower radial water permeability than a radial water permeability of any layer arranged outside the insulation system in the second sections.
