摘要： The invention relates to an electrical bushing serving to make a connection at ambient temperature to a superconductor element situated in an enclosure at cryogenic temperature. The electrical bushing passes successively through an enclosure at intermediate temperature between ambient temperature and cryogenic temperature, and an enclosure at ambient temperature, and it comprises a central electrical conductor surrounded by an electrically insulating sheath. According to the invention, an electrically conductive screen connected to ground potential surrounds the insulating sheath over a section that extends from the end of the bushing that is in contact with the enclosure at cryogenic temperature at least as far as the junction between the enclosure at intermediate temperature and the enclosure at ambient temperature. The invention is more particularly applicable to making a connection to a superconductor cable.

摘要： A termination for connecting one end of a superconductive cable (10), the end being made up of at least one resistively-conductive central support (12) of substantially cylindrical shape, of a superconductor (14, 16) disposed around the support, and of an insulating sheath (18) surrounding the superconductor. According to the invention, the end of the cable is stripped in order to reveal the central support (12) and the superconductor (14, 16), and the termination comprises a metal sleeve (30) made up of two portions adjacent in succession, a first portion (32) engaged around the stripped portion of the central support, and a second portion (34) soldered around the stripped portion of the superconductor. The invention is applicable to terminating high voltage cables.
