Electrical conductor for superconductive windings or switching paths

Abstract

Abstract An electrical conductor formed with a plurality of electrically insulated and transposed superconductor filaments braided together along the axial length thereof. Each filament is a thin flexible glass capillary filled with superconductive material. These capillaries are formed by heating and drawing a glass tube containing the superconductive material which has a melting temperature below that of the softening temperature of the glass. During the braiding process, filaments, of other materials, can be worked in with the capillaries and a hardenable material, such as casting resin, can be applied to the intermixed filaments and capillaries. The other filaments can be removed from the mass by a suitable process to provide a number of interconnected cavities in close proximity to the capillaries for passage of a cooling medium. The electrical or multiple-core conductor can also be positioned within a sheath in such a manner that passageways for cooling medium extend alongside the outer surface of the electrical conductor. The electrical conductors can be wound to produce windings or switching paths in which passageways for a cooling medium are provided.
