Claim of US Patent No. 9,496,073

1. A method comprising:
forming at least two protective layers around at least one high-strength alloy wire, said high strength alloy wire comprising
a plurality of filaments embedded in an Ag matrix, wherein a first protective layer is an Al2O3 passivation oxide layer and a second protective layer is a TiO2 non-reactive oxide layer;

coating at least one Superconducting wire with a protective layer;
arranging said at least one high-strength alloy wire and said at least one Superconducting wire to form a high-strength Superconducting
cable; and

treating said Superconducting cable with a heat treatment cycle.
