Claim:
1. A termination unit for a superconductive cable, the cable having at least one superconductive phase conductor, the termination unit comprising: an internal electrically insulating envelope containing the at least one phase conductor of the cable in a cryogenic fluid, the internal envelope having, for each phase conductor, one first electrical connector connected to the corresponding phase conductor and protruding from the internal envelope to the outside, wherein the termination unit further comprises an electrically conductive, grounded casing surrounding the internal envelope and the first electrical connectors with a distance to the internal envelope, the grounded casing comprising one bushing for each one of the first electrical connectors, each bushing being connected to one of the first electrical connectors by a second electrical connector, and being adapted to transmit voltage and current from its associated phase conductor, the grounded casing surrounds the internal envelope with such a distance that the respective first electrical connectors, the bushings and the second electrical connectors are covered by the grounded casing, the second electrical connector passes through the wall of the casing and protrudes from the same to the outside, and the termination unit is grounded in its entirety by electrically connecting the grounded casing to a cryogenic envelope of the cable.
