摘要： The present invention provides: a compound superconducting twisted wire in which non-adhesiveness between compound superconducting strands or separation easiness after adhesion is improved while a strength against tension is improved to a degree to be equivalent to or stronger than that of a conventional compound superconducting twisted wire; and a rewinding method thereof. The compound superconducting twisted wire 1 of the present invention includes a plurality of compound superconducting strands 10 being twisted to form a twisted structure, in which each of the compound superconducting strands 10 includes a compound superconductor part 11, a reinforcing part 12 and a stabilizing part 13, in which the compound superconductor part 11 includes a plurality of compound superconducting filaments 15 and a first matrix 16, the compound superconducting filaments 15 each including a compound superconducting phase, in which the reinforcing part 12 is disposed on an outer circumferential side of the compound superconductor part, and comprises a plurality of reinforcing filaments 18 and a second matrix 19, in which the stabilizing part 13 is disposed on at least one side of an inner circumferential side and an outer circumferential side of the reinforcing part. In the compound superconducting twisted wire, a volume ratio of the reinforcing part relative to the compound superconducting strand is larger than a volume ratio of the compound superconductor part relative to the compound superconducting strand, or a metal layer 20 with a thickness of 2 μm or less is formed on a surface of the compound superconducting strand for preventing thermal fusion between the compound superconducting strands.

摘要： An insulation-coated compound superconducting wire includes a compound superconducting wire having a compound superconducting part which includes a first matrix and a plurality of compound superconducting filaments containing compound superconducting phases, a reinforcing part disposed on the outer circumferential side of the compound superconducting part and includes a plurality of reinforced filaments, a second matrix and a second stabilizing material. A stabilizing part is disposed on at least one side among the inner circumferential side and the outer circumferential side of the reinforcing part. An electrical insulation part covers the outer circumferential surface of the compound superconducting wire, in which the insulation-coated compound superconducting wire has a critical current value (Ic) larger than that of the compound superconducting wire before being covered with the electrical insulation part.
