Abstract
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.
