Abstract
A compound superconducting twisted wire includes compound superconducting strands being twisted to form a twisted structure, in which each of the compound superconducting strands includes a compound superconductor part, a reinforcing part and a stabilizing part. The compound superconductor part includes compound superconducting filaments and a first matrix, the compound superconducting filaments each including a compound superconducting phase. The reinforcing part is disposed on an outer circumferential side of the compound superconductor part and includes reinforcing filaments and a second matrix. The stabilizing part is disposed on at least one side of an inner circumferential side and an outer circumferential side of the reinforcing part. 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.
