Abstract
A superconducting switch comprising a portion of cable including a resistive central strand that is non-superconducting having a plurality of super-conducting strands or of superconductors twisted thereabout, and separated from the central strand by electrical insulation, the cable as a whole being insulated from the external cooling medium by thermal insulation. The central strand is electrically connected to the superconducting strands or the superconductors at each end of a portion of cable. A portion of the length of the resistive central strand extends outside the cable at a point along the length of the portion of said cable and is coupled to a control device situated outside the cooling medium, wherein the control device injector an electrical current into the circuit formed by the resistive central strand that is connected at its ends to the superconducting strands or to the superconductors.
