Abstract
A composite superconductor having both filamentary and film conductors for carrying the pure and impure components of direct current, respectively, or for alternating current, is disclosed, together with a method of making it, and a preferred arrangement for its use in high power transmission lines.
Claims14
A composite superconductive tape having:
- (a) a rectangular central matrix element having a pair of wider faces and a pair of narrower faces when viewed in cross-section of a nonsuperconductive material in which are embedded a plurality of superconductive filaments;
- (b) a pair of layers of superconductive material bonded to said wider pair of faces of said matrix;
- (c) a pair of layers of a superconductive precursor material, selected such that it forms a superconductive compound when interreacted with the material of the matrix, bonded to said pair of layers of superconductive material;
- (d) a second pair of layers of superconductive material bonded to said pair of layers of superconductor precursor material;
- and
- (e) a pair of layers of a second nonsuperconductive material bonded to said second pair of layers of superconductive material.

A composite superconductive tape having:
- (a) a rectangular base matrix having a pair of wider faces and a pair of narrower faces when viewed in cross-section comprising a plurality of superconductive filaments embedded in a matrix of a normally conductive metal;
- (b) a layer of a superconductive material bonded to one of the wider faces of said matrix;
- (c) a layer of a superconductor precursor material bonded to said layer of superconductive material;
- (d) a second layer of a superconductive material bonded to said layer of superconductor precursor material;
- and
- (e) a layer of a material selected from the group consisting of copper, aluminum, gold, silver, stainless steel, molybdenum and tungsten bonded to said second layer of superconductive material.
