MANUFACTURE OF HIGH CRITICAL TEMPERATURE SUPERCONDUCTIVE TWISTED COVERTED WIRE

摘要

PROBLEM TO BE SOLVED: To provide an attractive manufacturing method of a stranded covered superconductor with high critical temperature. SOLUTION: This wire is made of billets produced by assembling single core wires having a square section in a metal pipe having a square section. A multi-core wire 5 is stranded at a certain pitch (p) and rolled by a roll having a larger dia. than the pitch. Such a wire provided by use of the above method is applicable to a variable current.
