Abstract:
In a method for making superconductor cable, the steps comprising:(a) encasing a multiplicity of filaments of a superconductor alloy in a normally conducting metal matrix to form superconductor wire;(b) electroplating with nickel said superconductor wire to provide a nickel coating about the periphery thereof;(c) forming an elongated bundle of generally circular cross section from a multiplicity of strands of said electroplated superconductor wire; and(d) deforming and compacting said bundle of strands into a superconductor cable of generally polygonal cross section, said nickel coating on said strands substantially maintaining its integrity in said cable, and said strands exhibiting only negligible diffusion of nickel into the matrix metal of said superconductor wire, said cable exhibiting relatively high interstrand resistance.
