    • A high voltage power cable termination with a current lead, a power cable having a first tube and an outer conductor, e.g., a superconductor, whose electrically conducting properties improve at low temperatures, arranged around the first tube and intended in use to be cooled to low temperatures by cryogenic fluid flowing through the first tube, a joint for electrically connecting one end of the current lead to the conductor at one end of the cable at or adjacent to one of the first tube, and a second tube communicating with the first tube at or adjacent to the joint for conveying cryogenic fluid to or from the first tube. The first and the second tube are arranged so that, in use, no cryogenic fluid conveyed by the tubes contacts the conductor or the current lead at the joint. The invention also relates to electrical apparatus, e.g., a high voltage induction device, having such a termination.
    • 一种具有电流引线的高压电力电缆终端,具有第一管和外部导体的电力电缆终端,例如超导体,其导电性能在低温下改善,其布置在第一管周围,并且用于冷却至 通过流过第一管的低温流体的低温,用于将电流引线的一端电连接到电缆的一端处于或邻近第一管的导体的接头,以及与第一管连通的第二管 在或接近用于将低温流体输送到第一管或从第一管输送的接头。 第一和第二管被布置为使得在使用中,由管输送的低温流体不接触接头处的导体或电流引线。 本发明还涉及具有这种终端的电气装置,例如高压感应装置。
