OXIDE SUPERCONDUCTING WIRE MATERIAL AND SUPERCONDUCTING WIRE MADE THEREFROM

摘要

PURPOSE:To provide both an oxide superconducting wire material which has an insulating layer excellent in thickness uniformity and exhibiting sufficient dielectric strength and can efficiently be wound into coil configuration or the like without dropping the insulating layer, and a superconducting wire made therefrom. CONSTITUTION:An oxide superconducting wire material is obtained by providing more than one or two unsintered oxide superconducting wires 3 inside a metallic sheath layer 1 via an inorganic insulating layer 2 and subjecting the wires to drawing process, the superconducting wires 3 having a metal cover layer 31. The unsintered oxide superconducting wires are then sintered.
