Hillmann, H; Springer, E

A superconducting composite conductor is disclosed that consists of several strands with a superconductive intermetallic compound of at least two elements, and at least one strand of a thermally and electrically highly conductive stabilizing metal which is normally conducting at the operating temperature of the superconducting composite conductor, wherein the strands with the superconductive compound each contain a core of at least one higher melting point element of the compound, having, at least on its surface, a layer of the compound, embedded in an alloy of at least one lower melting point element of the compound and a carrier metal in the form of a cable, stranded wire or flat cable , the strand of the stabilizing metal is joined to the adjacent strands containing the superconductive compound by diffusion of at least one lower melting point element of the compound and contains at least one zone, which zone extends along the strand and is enclosed by a diffusion inhibiting layer.
