Patent ID: 8670808

Claim:
System having at least one superconducting cable comprising: at least one superconducting conductor; and a cryostat which surrounds the superconducting conductor, said cryostat having two metallic tubes, an inner tube and an outer tube, which are arranged concentrically at a distance from one another, are corrugated transversely with respect to their longitudinal direction and between which vacuum insulation is arranged wherein the cable has a central tubular support for passing a coolant through, on which the superconducting conductor rests, the cable is surrounded all around by an insulating material buffer layer which protects the same against mechanical damage, wherein the corrugation of the inner tube of the cryostat which faces inwards, penetrates at least slightly into the buffer layer, and wherein the cable and the inner tube of the cryostat are in a wavelike form within the outer tube of cryostat such that for a given longitudinal distance, their linear lengths are approximately 0.3% greater than said longitudinal distance.
