Insulation coating oxide superconducting wire and resin impregnated superconducting coil

摘要

PROBLEM TO BE SOLVED: To provide an insulating coating oxide superconducting wire and a resin impregnated superconducting coil which can prevent deterioration in superconductivity characteristics caused by a peel force that a release agent layer is peeled off by cooling or the like and sufficiently removes heat for preventing burnout even if the resin impregnated superconducting coil generates heat.SOLUTION: The insulating coating oxide superconducting wire 21 is formed as follows. An insulating material layer 2 is formed and coated on the whole peripheral surface of an RE-type oxide superconducting wire material 1 formed of a flat wire, so that the insulating material layer has a substantially equal thickness. A release agent layer 22 is formed on the outer surface of the insulating material layer 2. The release agent layer 22 is formed only on a part of the outer surface of the insulating material layer 2. The insulating coating oxide superconducting wire 21 is wound and formed into a coil, and then, impregnated with a heat-curing synthetic resin 23 so as to form a winding part 25, thereby obtaining a resin impregnated superconducting coil 24.
