Abstract
A superconducting cable comprising at least a superconducting conductor and a cryostat, including a thermal insulation and an inner tube, with a protecting element between the superconducting conductor and the inner tube, to prevent damages to the superconducting material by the inner tube of the cryostat.
Claims20
A Superconducting cable comprising:
- a support with an inner surface which defines a channel wherein a cryogenic fluid flows;
- a superconducting conductor positioned externally to said support;
- a cryostat positioned externally to the superconducting conductor, said cryostat including a thermal insulation enclosed between an inner tube and an outer coaxial tube;
- a protecting element positioned between the superconducting conductor and the inner tube of the cryostat;
- an electric insulation layer positioned externally to said cryostat.
