Arrangement with a superconductive cable

Arrangement for an electrically conducting connection of a superconductive electric cable with a cable having normal conductivity at room temperature, where the cable includes a passage with an electric conductor which is surrounded by thermal insulation, in which the superconductive cable is arranged in a tubular cryostat for guiding a cooling agent, and where the conductor of the superconductive cable is connected to an end of the conductor of the passage, and whose other end is connectable to the cable having normal conductivity, wherein:

• on the end of the superconductive cable intended in connection to the conductor of the passage is mounted in the manner known per se an electrode serving for the electric field control;
• that the end of the cable is surrounded by a circumferentially closed sheath constructed as a pipe piece of electrically insulating material with a vacuum-free thermal insulation which is provided on its outer surface with a layer of vacuum-free thermally insulating material;
• and
• that the end of the sleeve facing the passage is placed during the state of operation of the arrangement at high voltage potential, while the other end is connected to ground potential.
