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.
