Specified is an arrangement for supplying power to a motor vehicle which is equipped with an electric motor and in which there is arranged at least one rechargeable electric battery to which the electric motor is connected. The arrangement includes a stationary charging station which is equipped with an electric power source and to which an electric line having at least two mutually insulated electrical conductors is connected, a part of an electrical coupling for connecting to a complementary coupling part present on or in the motor vehicle being attached to the free ends of said electrical conductors, said coupling part being connected to the battery in an electrically conductive manner. The electric line is surrounded along its entire axial length by a thermally insulated and flexible tube made of metal which is closed all around and which, in addition to the line, encloses a cavity along its entire axial length. A flowable medium refrigerated to a temperature of at least 160 C. is contained in the space enclosed by the tube, and a thermally insulated storage tank containing a store of the refrigerated medium is arranged in the charging station, the tube being connected to said storage tank.

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.

The present invention provides a system and method for producing superconducting joints between superconductive segments of a Bi-2212 high-temperature superconducting (HTS) conductor, thereby eliminating the heat generating resistive joints that are commonly known in the art for connecting two or more smaller Bi-2212 conductive segments to create an Bi-2212 conductor of adequate length.

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.
