SUPERCONDUCTIVE CABLE AND MANUFACTURING METHOD OF SUPERCONDUCTIVE CABLE

PROBLEM TO BE SOLVED: To secure a suitable conductive volume capable directly connecting a plurality of conductive wire materials each other via a solder easily and less in connection resistance.SOLUTION: A superconductive cable has a core material, an insulation paper arranged on an outer periphery of the core material, first superconductive wire materials and second superconductive wire materials which have a plurality of superconductive wire materials wound around the outer periphery of the core material via the insulation paper and of which superconductive wire materials are connected by solder, and a solder preventive film which is would on the insulation paper between the insulation paper and the first superconductive wire materials and the second superconductive wire materials, has conductivity and prevents the solder from flowing into the insulation paper. A plurality of superconductive wire materials of the first superconductive wire materials and the second superconductive wire materials are arranged by layering on the solder preventive film each other and solder connected at a temporary fixed state by a temporary fixed member arranged on the outer periphery of layered superconductive wire materials.SELECTED DRAWING: Figure 2 【課題】複数の超電導線材同士を、ハンダを介して容易に直接接続でき、接続抵抗のばらつきが少ない好適な通電容量を確保すること。【解決手段】芯材と、芯材の外周に配置された絶縁紙と、絶縁紙を介して芯材の外周に複数巻き付けられる超電導線材をそれぞれ有し、互いの超電導線材同士がハンダ接続される第１超電導線材群及び第２超電導線材群と、絶縁紙と、第１超電導線材群及び第２超電導線材群との間で、絶縁紙に巻き付けられ、且つ、導電性を有し、ハンダの絶縁紙への流入を防止するハンダ防止膜と、を有する。第１超電導線材群と第２超電導線材群のそれぞれの複数の超電導線材同士は、ハンダ防止膜上で重ねて配置されるとともに、重なる複数の超電導線材同士の外周に配置された仮止め部材により仮止め固定された状態でハンダ接続されている。【選択図】図２
