Process for manufacturing a power cable includes: providing a power cable core having an electric conductor; providing a copper foil; providing a protective strip over the power cable core, the protective strip having a radially inner and outer surface and being made of copper with a coating; folding the copper foil around the power cable core so as to bring two longitudinal copper foil rims to contact one to the other; welding the two contacted longitudinal copper foil rims thus obtaining a copper sheath in form of a tube with a welding seam; reducing the diameter of the copper sheath to put it into direct contact with the power cable core and the protective strip; heating the protective strip and the copper sheath at a temperature higher than the melting temperature of the coating of the strip so that the coating fuses in the welding seam.

A wire restricting member includes a bottom plate portion and a pair of side plate portions. The pair of side plate portions vertically extend from opposite ends of the bottom plate portion along a longitudinal direction of the bottom plate portion, respectively. Upper ends of the pair of the side plate portions in a direction in which the pair of the side plate portions vertically extend are distant from each other to form an opening therebetween. Each of the pair of the side plate portions includes a notch which is cut from each of the upper ends to the bottom plate portion.

A method of manufacture for a subsea power cable (100), includes the step of providing at least one cable core (125) having an electrical conductor (110) and an electrically insulating system (120) arranged radially outside of the electrical conductor (110). The method includes adding a liquid material having a polymer, on top of the at least one cable core (125), forming a buffer layer (130); and applying a water barrier (140) radially outside of the buffer layer (130).

An arrangement is provided for electrically connecting two devices (2, 3) located in a plant. Between the two electrical devices (2, 3) at least one electric line (4) formed of metal is arranged between the two electrical devices (2, 3) surrounded by a screen. The screen, (5) is constructed as metal pipe (5) which is at least partially undulated and is connected at both, ends each with an electrically conductive housing of the two electrical devices (2, 3).

A method of manufacturing a dynamic submarine power cable, the method including: a) providing an insulation system around a 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, b) providing a semiconducting polymeric layer around the outer semiconducting layer, c) providing a longitudinally welded metallic radial water blocking layer around the polymeric layer, the metallic radial water blocking layer being in contact with the polymeric layer, and d) heating the metallic radial water blocking layer after step c) such that the polymeric layer melts and forms an adhesive layer that adheres to an inner surface of the metallic radial water blocking layer.

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.
