OXIDE SUPERCONDUCTOR, MANUFACTURE THEREOF, AND OXIDE SUPERCONDUCTING POWER CABLE HAVING THE SUPERCONDUCTOR

摘要

PURPOSE:To provide an oxide superconductor in which strain applied to a superconductive tape is small compared with a traditional manufacturing method fixing individual superconducting tape unit, the winding and fixing of a superconducting tape are easy, and deterioration in superconductivity is small, and to provide the structure and manufacture of a superconducting cable. CONSTITUTION:A superconductive tape unit 15 is formed by stacking plural pieces of superconducting tape with an oxide superconducting core on the inside of a tape-like sheath made of a conductive metallic material. Plural superconducting tapes 15 are fixed in parallel on one surface of a tape base material 14 with electric conductivity and heat conductivity to form a tape aggregate 13. The tape aggregate 13 is spirally wound and fixed on the outer circumference of a tube 12 with electric conductivity and heat conductivity.
