Abstract
A superconductive cable which has a cryostat with two concentric metal pipes where the cryostat has at least a first axial section with a first axial spring constant, and at least a second axial section which has a second axial spring constant which at most is 20%, more preferred at most 10%, of the axial spring constant of the first section.
Claims5
System with a superconductive cable and a cryostat, which surrounds the superconductive cable said system comprising:
- a cryostat includes an outer corrugated pipe and a concentric inner corrugated pipe with an insulation, arranged between the two pipes, wherein the cable is arranged along the cryostat in the inner corrugated pipe, wherein the cable core is fixed at each end of the cryostat to the same and wherein
- the cryostat has in a first axial section a helically-shaped corrugation with a first specific spring constant in the axial direction, and, in a second axial section a ring-shaped corrugation with a second specific spring constant in the axial direction, which at most is 20% of the first specific spring constant.
