摘要： A high-voltage cable sealing end (100) has a primary volume (102) and a secondary volume (104) fluidically connected thereto, which are filled with an insulating fluid. The primary volume (102) and the secondary volume (104) are sealed with respect to the atmosphere surrounding the high-voltage cable sealing end (100). The secondary volume (104) can be disconnected from the primary volume (102) via a separable connection (106) which can be cut off in a fluid-tight manner. A drying agent, which draws moisture out of the insulating fluid, is introduced into the secondary volume (104).

摘要： A joint is provided between two abutting cables, where the cables each have, around a central support, at least one phase layer composed of at least one layer of superconducting material and a neutral layer that are concentric and contained in a shell, filled with cryogenic fluid. The neutral layer of each cable is also stripped, at least one bridging support member is placed between the stripped neutral layers, and a layer of conducting or superconducting material, for, the electrical connection of these neutral layers, is placed on the support member.

摘要： An electrically connecting device (1) includes a linking part defining an internal channel (12) that opens onto the exterior of the linking part. The internal channel (12) is able to receive two end segments of two superconducting wires (2, 3) that lie parallel in the internal channel (12) over a segment of common length; and an aperture (13) in the external jacket of the linking part. The aperture (13) is in communication with the internal channel (12) in order to allow a brazing material in liquid form to be inserted into the internal channel (12) around the two end segments of the two superconducting wires (2, 3).

摘要： The invention specifies a termination (1) for a superconducting cable (2) which is arranged in a tubular cryostat, which serves for carrying a coolant, and has at least one electrical conductor. The termination (1) has an inner sheath (3), in which one end of the cable (2) is arranged in a coolant, and an outer sheath (4), wherein the sheaths (3, 4) are composed of electrically insulating material and insulating material is arranged in an existing intermediate space (5) between the inner and the outer sheath. The inner sheath (3) is connected to the cryostat, and the termination (1) is arranged vertically in the assembly position such that a lower part (C) of the inner and the outer sheath (3, 4) is connected to earth and an upper part (A) of the inner and the outer sheath (3, 4) is connected to high-voltage potential in the operating state. At the respective upper end, the inner sheath (3) is closed off by a first bursting disc (3a) and the outer sheath (4) is closed off by a second bursting disc (4a).

摘要： 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).
