Patent number: 9331468Abstract: Cable end section comprises end-parts of N electrical phases/neutral, and a thermally-insulation envelope comprising cooling fluid. The end-parts each comprises a conductor and are arranged with phase 1 innermost, N outermost surrounded by the neutral, electrical insulation being between phases and N and neutral. The end-parts comprise contacting surfaces located sequentially along the longitudinal extension of the end-section. A termination unit has an insulating envelope connected to a cryostat, special parts at both ends comprising an adapter piece at the cable interface and a closing end-piece terminating the envelope in the end-section. The special parts houses an inlet and/or outlet for cooling fluid. The space between an inner wall of the envelope and a central opening of the cable is filled with cooling fluid. The special part at the end connecting to the cryostat houses an inlet or outlet, splitting cooling flow into cable annular flow and termination annular flow.Type: GrantFiled: November 26, 2013Date of Patent: May 3, 2016Assignee: NKT CABLES ULTERA A/SInventors: Chresten Traeholt, Dag Willen, Mark Roden, Jerry C. Tolbert, David Lindsay, Paul W. Fisher, Carsten Thidemann Nielsen

Patent number: 8623787Abstract: The invention relates to a superconductive multi-phase, fluid-cooled cable system comprising a) a cable comprising at least three electrical conductors constituting at least two electrical phases and a zero- or neutral conductor, said electrical conductors being mutually electrically insulated from each other, and b) a thermal insulation defining a central longitudinal axis and having an inner surface and surrounding the cable, said inner surface of said thermal insulation forming the radial limitation of a cooling chamber for holding a cooling fluid for cooling said electrical conductors. The invention further relates to a method of manufacturing a cable system and to its use. The object of the present invention is to provide a simplified manufacturing and installation scheme for a fluid cooled cable system.Type: GrantFiled: November 1, 2012Date of Patent: January 7, 2014Assignee: NKT Cables Ultera A/SInventors: Dag Willen, Chresten Traeholt, Manfred Daumling, Jerry C.
