Abstract
A superconducting wire is produced by the surrounding of a superconductive material core with an intermediate compressible insulating layer and an outer malleable layer and then drawing said composite structure through a series of dies to reduce the diameter of the wire on the order of 400 to 10,000 times or by reducing the superconductive core material to the desired wire size by passing it through a series of dies to reduce the diameter of the wire on the order of 400 to 10,000 times and then coating the wire with a noncompressible insulating layer and then placing an outer malleable layer over the insulated wire and drawing this through dies to snuggly fit the outer layer onto the insulated wire. This wire's superconducting characteristics are not intended for carrying high levels of currents so the reduction of the available current carrying cross section by the introduction of the insulating layer is not of concern in the applications for the wire. Low and high temperature high level current-carrying superconductors lose their superconductivity with changes in their critical temperature and critical magnetic field. A loss in superconductivity in a high current-carrying superco…
