Abstract
An arrangement for electrically conductively connecting two electrical units by means of a bipolar high voltage direct current transmission, in which between the units are arranged at least two electrical direct current cables constructed as superconductive cables. The superconductive cables are mounted separately from each other in a cryostat () suitable for conducting a cooling agent which has at least one metal pipe provided with a thermal insulation. The cryostats () are connected with at least one of their ends to a cooling plant () supplying the cooling agent and a pipeline () is placed parallel to the two cryostats (). The pipeline () is connected at both its ends to the two cryostats () through valves () which are closed during uninterrupted operation and, in the case of an interruption at one of the superconductive cables, the pipeline () serves with the then open valves for conducting the cooling agent intended for the cryostat of the impaired cable.
