Because a large current cannot be passed through a single strand,
It is necessary to bundle a large number of strands. Until now, three to four layers of tape-shaped Bi (2223) phase superconducting wire (element ratio of Bi: Sr: Ca: Cu = 2: 2: 2: 3) have been spirally wound around a former (pipe). Rutherford cables are produced by compression molding of a collective conductor and 20 Bi (2212) phase round wires.

However, heat escapes to the former and the superconducting wire, so that the soldering work is difficult. did. Furthermore, as a result of the conduction test, it was impossible to uniformly supply a current to each superconducting wire. In the case of the Bi (2212) phase Rutherford cable, the wire at the end was loosened and soldered.
As in the case of the Bi (2223) phase aggregate conductor, heat escaped and the soldering work was difficult. In the energization test, the current could be applied uniformly to each strand, but the wire was deteriorated due to handling when the strand was loosened.

る。As a method of attaching a current terminal, there is a method of attaching a crimp terminal as used in a general cable. However, when this method is applied to an oxide superconducting collective conductor,
Because the wire material of the crimped part is large deformation (high processing rate),
There is a problem that the superconducting wire is liable to be broken and deteriorated.

There is a drawback that it is difficult to uniformly apply a current to each strand, and a crimp terminal has a drawback that the superconducting wire is broken or deteriorated.
