SUPERCONDUCTIVE CURRENT LEAD

摘要

PROBLEM TO BE SOLVED: To solve such a problem that a protective layer may be highly possibly decayed during a process of soldering since a metallic electrode is enlarged to increase a current capacity of a superconductive current lead, thus resulting in an increase of a heat capacity.SOLUTION: In the superconductive current lead 20, a plurality of current lead units 1 in each of which a protective layer side of a high temperature superconductive tape wire 2 having the protective layer 15 formed on a superconductive layer 13 is electrically connected with the metallic electrode 3 via first solder 4 are electrically connected via second solder 5 with a lower melting point than that of the first solder 4.
