Method for producing superconducting cable and cable produced thereby

摘要

A superconductor cable with high interstrand resistance is produced from superconductor wire strands which has been electroplated with nickel. The wire strands have filaments of a superconductor alloy in a normally conducting metal matrix and are electroplated before they are formed into an elongated bundle of generally circular cross section. This bundle is then deformed and compacted into a superconductor cable of generally polygonal cross section which is usually trapezoidal. The superconductor wire is preferably comprised of a multiplicity of filaments of niobium/titanium superconductor alloy disposed within a matrix of copper.
