A joint arrangement for a submarine cable, in which armoured submarine cables are joined together, the joint arrangement including a tubular enclosure into which two submarine cables to be joined are to extend and inside which conductors of the two submarine cables are joined, wherein the enclosure includes a current-carrying part arranged so as to be able of conducting at least a part of a current conducted by the armouring of the cables, and a reinforcement part provided to provide sufficient mechanical strength to the enclosure and made of a material of lower electrical conductivity than the material of the current-carrying part. The current-carrying part is integrated in the reinforcement part and forms a single unit therewith.

Joint for a submarine cable

An installation for transmission of electric power via a high-voltage ac voltage line between two switchgear units located at a large distance from each other. For the transmission of the electric power, the ac voltage line includes at least one extruded cable with an inner electric conductor, an insulating layer of a solid material surrounding the conductor, and an outer screen layer located at ground potential. The installation also includes one or more inductors located along the extent of the cable between the switchgear units and integrated into the cable. The inductors are connected between the conductor of the cable and ground for reactive shunt compensation.
