Title:
PRECURSOR WIRE FOR COMPOUND SUPERCONDUCTING WIRE, COMPOUND SUPERCONDUCTING WIRE, AND REWINDING METHOD FOR COMPOUND SUPERCONDUCTING WIRE
Document Type and Number:
WIPO Patent Application WO/2023/013726
Kind Code:
A1
Abstract:
This precursor wire (1) for a compound superconducting wire includes: a compound superconducting precursor section (10) configured from a plurality of compound superconducting precursor filaments (11) and a first matrix precursor (12) that includes a first stabilizing material and in which the compound superconducting precursor filaments are embedded; a reinforcing material section (30) configured from a plurality of reinforcing filaments (31) arranged on the outside of the compound superconducting precursor section and a second matrix (32) that includes a second stabilizing material and in which the reinforcing filaments are embedded; and a cylindrical stabilizing material section (40) that comprises a third stabilizing material and is arranged on at least one of the inner circumferential side and the outer circumferential side of the reinforcing material section. The aspect ratio Ab1(Wb1/Tb1) of the width dimension Wb1 of the compound superconducting precursor section to the thickness dimension Tb1 in a cross section perpendicular to the lengthwise direction of the compound superconducting precursor section is 1.80 or more.
