Oxide superconducting wire manufacturing method

摘要

A long oxide superconducting wire for a coil or a cable, manufacturing method thereof, an oxide superconducting coil and a cable conductor which have high operational frequency are provided. The wire is a tape-like oxide superconducting wire including a plurality of filaments of oxide superconductor embedded in a matrix, and each filament is twisted spirally along the longitudinal direction of the tape wire. By winding the wire in a coil, an oxide superconducting coil is obtained. When a plurality of such wires are collected, an oxide superconducting cable conductor can be obtained.
