Abstract: 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).

Abstract: The present disclosure relates to DC transmission. Some embodiments may include a device for DC transmission comprising: a superconducting transmission line including a superconducting conductor element; and a cooling device for cooling an inner region of the transmission line with a fluid coolant to a temperature below a critical temperature of the superconducting conductor element. The superconducting transmission line may comprise a vacuum-insulated sleeve thermally isolating the inner region of the transmission line from a warmer outer surrounding area. The cooling device may comprise a feed device feeding coolant at an end region of the transmission line into the inner region of the transmission line. The transmission line may be free of internally arranged feed devices for feeding coolant at locations away from the end region.

Abstract: A method of connecting prefabricated pieces of an HTS cable onsite is disclosed. This quick and reliable procedure of connecting pieces of HTS cable adds to the flexibility of designing and installing power transmission and distribution grids. The joint can also be dissembled such that it can be dismantled for replacing the cable on one side of the connection. The joint can then be reassembled with a new cable in its place. This facilitates repairing the electrical grid in case of local damage to the cable, as well as reconfiguring the grid in case this is required. The complexity of creating demountable HTS cable joints is due to the necessity to create and maintain continuity of several media across the joint along the length of the cable. Various combinations of design options satisfying these requirements are possible.

Abstract: In order to obtain a highly versatile superconducting cable capable of absorbing differences in thermal contraction amounts that arise between three members, these being a cable core, an inner tube, and an outer tube, and to obtain a superconducting cable manufacturing method of the same, a superconducting cable includes a thermal insulation vacuum tube and a cable core. The thermal insulation vacuum tube includes an inner tube fixed at both ends and having a cooling medium filled inside, and an outer tube disposed at an outer peripheral side of the inner tube with a space between the outer tube and the inner tube maintained at a vacuum, and is configured to include a winding section wound with one or more turns. The cable core is fixed at both ends and disposed inside the inner tube.

Abstract: A method of cooling at least one superconductive cable is disclosed which is arranged in a cryostat having at least one thermally insulated pipe with a free space surrounded by the pipe, wherein the cable and at least one tubular structure are arranged in the free space, and wherein a cooling agent is conducted through the free space from a feeding point located at one end to a distal end. The cooling agent is conducted through the cryostat and the tubular structure exclusively in one direction of the cable until it reaches its temperature of operation and is discharged to the outside at the distal end. After reaching the temperature of operation, the cooling agent is returned from the distal end of the arrangement through the tubular structure to the feeding point.
