A superconducting cable capable of absorbing contraction of a superconducting wire through a simple arrangement at the time of cooling. The superconducting cable comprises a superconducting wire wound spirally to constitute a superconducting layer (conductor layer (13), return conductor (17)), a stress relaxation layer (inner stress relaxation layer (12), insulating layer/outer stress relaxation layer (16)) provided on the inside of the superconducting layer, and a cable composing member (former (11)) provided on the inside of the stress relaxation layer. The stress relaxation layer is arranged to absorb contraction of the superconducting layer in the radial direction incident to cooling of the superconducting wire by coolant.
L~invention concerne un câble supraconducteur capable d~absorber le rétrécissement d~un fil supraconducteur au moment du refroidissement grâce à un montage simple. Le câble supraconducteur comprend un fil supraconducteur enroulé en spirale pour former une couche supraconductrice (couche conductrice (13), conducteur de retour (17)), une couche de relaxation des contraintes (couche de relaxation des contraintes intérieure (12), couche isolante / couche de relaxation des contraintes extérieure (16)) formée sur l~intérieur de la couche supraconductrice, et un élément de mise en forme de câble (formeur (11)) monté sur l~intérieur de la couche de relaxation des contraintes. La couche de relaxation des contraintes est conçue pour absorber le rétrécissement de la couche supraconductrice dans la direction radiale associé au refroidissement du fil supraconducteur par un fluide de refroidissement.
