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 joint, termination or cross-connection arrangement for a cable includes a first cable and a protective casing. The arrangement further includes a transition sleeve. The transition sleeve, at a first longitudinal end surface thereof, is welded to the metallic sheath of the first cable around the whole circumference of the metallic sheath. The transition sleeve is furthermore welded to the protective casing around the whole circumference of the transition sleeve. A method of providing such an arrangement includes: welding the transition sleeve, at the first longitudinal end surface, to the metallic sheath of the first cable around the whole circumference of the metallic sheath; and welding the transition sleeve to a first tubular end portion of the protective casing around the whole circumference of the transition sleeve.
