超電導コイルおよび超電導線材
Document Type and Number:
Japanese Patent JP6555641
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a technique that properly prevents damage of a superconducting layer caused by shrinkage of an epoxy resin layer under cooling while simplifying a manufacturing process and reduce the material cost, whereby a superconducting coil which is difficult to be reduced in Ic can be easily achieved at low cost.SOLUTION: A tape-like superconducting wire rod having a superconducting layer formed on the surface of a metal substrate is wound, and impregnated in an epoxy resin composition to achieve a superconducting coil having an epoxy resin layer between the wound superconducting wire rods. In the superconducting coil, at least one surface of the superconducting wire rod is provided with an insulation resin layer formed of resin having insulation property, and the insulation resin layer is an insulation resin layer which is broken with weaker force than the breaking strength of the superconducting layer.SELECTED DRAWING: Figure 1
