Abstract: An arrangement is provided having a superconductive cable (SK) which consists of a superconductive conductor (1) and a superconductive screen (3) that encloses the latter with the interposition of a dielectric (2) and which is enclosed, with the inclusion of a free space (FR) for conveying a refrigerant, by a cryostat (KR) which consists of two metal tubes (4,5) arranged mutually concentrically, between which vacuum insulation (6) is arranged. Outside the screen (3), a tubularly closed layer (7, 8) of a ferromagnetic material is provided over the entire length of the cable (SK). It is preferably arranged on the outer circumference of the cryostat (KR).

Abstract: An arrangement for current limiting is specified, using components (4, 5, 6) composed of a superconducting material which are arranged in a cryostat (KR) which comprises two metallic tubes (1, 2) which are arranged concentrically with respect to one another and between which vacuum insulation (3) is fitted, and which cryostat surrounds a free space (FR) for a coolant to pass through. The components (4, 5, 6) each comprise three phase conductors (7, 8, 9) composed of a superconducting material based on rare earths (ReBCO), which are arranged insulated from one another and concentrically with respect to one another.

Abstract: An arrangement is specified for current limiting having a superconducting cable (SK) which is arranged in a cryostat (KR) which has an outer wall which comprises two metallic tubes (1, 2) which are arranged concentrically with respect to one another and between which vacuum insulation (3) is incorporated. The cryostat (KR) surrounds a free space (FR) for a coolant to pass through, in which free space (FR) the superconducting cable (SK) is arranged. It also has an inner wall (IW) which surrounds a cylindrical cavity (HR) and likewise comprises two metallic tubes (4, 5) which are arranged concentrically with respect to one another, between which vacuum insulation (6) is incorporated, and which is located within the outer wall (AW) and is separated therefrom by the free space (FR). The superconducting cable (SK) which has a superconducting conductor, a dielectric surrounding the same and a superconducting screen which is arranged above the same, is wound in a helical shape around the inner wall (IW).

Abstract: An arrangement is specified having a superconducting cable (SK) which comprises a superconducting conductor (1) and a superconducting screen (3) which concentrically surrounds the same with the interposition of a dielectric (2). The cable (SK) is surrounded by a cryostat (KR) enclosing a free space (FR) for a coolant to be passed through, which cryostat (KR) which cryostat comprises two metallic tubes (4, 5) which are arranged concentrically with respect to one another and between which vacuum insulation is arranged. The screen (3) is composed of a superconducting material whose electrical resistance value in the normally conductive state is greater by a factor of at least 50 than the electrical resistance value of the material used for the conductor (1) in the normally conductive state.

Abstract: A method for laying a superconductor cable having a superconductive cable core and a cryostat enclosing the superconductive cable core, with the superconductive cable core being arranged freely mobile in the cryostat. The method includes cooling the superconductive cable core to the operating temperature after laying the superconductor cable, shortening the superconductive cable core relative to the cryostat, fixing the superconductive cable core at its ends; and mounting terminations on the ends of the cable core.
