STRUCTURE OF INTERCONNECTING SUPERCONDUCTING CABLE, AND METHOD OF CONNECTING SUPERCONDUCTING CABLE

PROBLEM TO BE SOLVED: To provide a low loss structure of interconnecting superconducting cables, and a method of connecting superconducting cables for use in configuring the interconnection structure.SOLUTION: A structure 1 of interconnecting superconducting cables comprises: a connecting sleeve 2 interconnecting formers 110A and 110B and having about the same outside diameter as the formers; connection part wire rod layers 31, 32, ... including a plurality of parallel connecting superconducting wire rods 3 and interconnecting superconducting wire rods constituting cable wire rod layers 121A and 121B (122A, 122B, ...) constituting superconductors; and connection part insulating layers 41, 42, ... arranged so as to bridge interlayer insulating layers 131A, 131B, ... and interposed between the connection part wire rod layers 31, 32, ... With the connection insulating layers 41, 42, ..., the interconnection structure 1 can reduce a loss due to a skin effect. Helical winding of the connecting superconducting wire rods 3 can reduce a connection resistance, so that the interconnection structure 1 also implements a low loss in this regard.
