  • Publication number: 20120053061
    Abstract: A method of managing thermal contraction of a superconductor cable (2) having a cable body surrounded by an external screen (2A) made form wound metal elements and installed between its ends in an enclosure (1) or cryostat filled with a cryogenic liquid, where the method includes mechanically applying a locking force loading only said screen (2A) at a so-called locking point (5A, 5B) in the vicinity of the ends of the cable.

  • Publication number: 20110294669
    Abstract: A superconductive electrical direct current cable with at least two conductors insulated relative to each other is indicated, where the cable is placed with at least two conductors insulated relative to each other, where the conductors are arranged in a cryostat suitable for guidance of the cooling agent, wherein the cryostat is composed of at least one metal pipe which is surrounded by a circumferentially closed layer with thermally insulating properties. In the cryostat is arranged a d-shaped carrier composed of insulating material, where the carrier has at least two diametrically oppositely located outwardly open grooves in each of which is arranged one of the conductors. Each conductor is composed of a plurality of superconductive elements.
