  • Patent number: 9058917
    Abstract: A submarine power cable (10) has an electrical conductor (1) surrounded by an insulation (2,3,4), said insulation being surrounded by a metallic moisture barrier (5) characterized in that the cable (10) further comprises a semi-conductive adhesive layer (6) surrounding said metallic moisture barrier (5), and a semi-conductive polymeric jacket (7) able to be in electrical contact with sea water surrounding said semi-conductive adhesive layer (6), the overlaying of the metallic moisture barrier (5), the semi-conductive adhesive layer (6) and the semi-conductive polymeric jacket (7) forming a 3-layer sheath.
