Abstract: 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.

Abstract: The method of the invention enables the manufacture of flat, rectangular cable from fine-gauge, self-bondable magnet wire. The cable is capable of efficiently transmitting electrical currents at high frequencies.

Abstract: A cable comprised of coated conductors, wound together and compacted, has an insulating strip interposed between the two layers in which the conductors are disposed, to ensure good insulation therebetween. Apparatus for producing the cable includes a stranding machine, with which a hollow mandrel is used for the purpose of introducing the insulating strip between the layers of conductors, and a method for producing the cable is also provided.
