Title:
超電導ケーブルおよび超電導ケーブルの製造方法
Document Type and Number:
Japanese Patent JP6722564
Kind Code:
B2
Abstract:
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
