Abstract

A termination unit (1) for a superconducting cable (3), has an internal electrically insulating envelope (2) containing the phase conductors (3A, 3B, 3C) of the cable (3) in a cryogenic fluid. The internal envelope (2) has, for each phase conductor (3A, 3B, 3C), one first electrical connector (6A, 6B, 6C) connected to the corresponding phase conductor (3A, 3B, 3C) and protruding from the internal envelope (2). The termination unit (1) further has an electrically conductive, grounded casing (7) surrounding the internal envelope (2) and the first electrical connectors (6A, 6B, 6C), the grounded casing (7) comprising one bushing (8A, 8B, 8C) for each one of the first electrical connectors (6A, 6B, 6C), each bushing (8A, 8B, 8C) being connected to one of the first electrical connectors (6A, 6B, 6C) by a second electrical connector (9A, 9B, 9C) and being adapted to transmit voltage and current from its associated phase conductor (3A, 3B, 3C).
