Patent ID: 10961399

Abstract:
A method of manufacturing an insulated flat long-length second-generation HTS wire by preparation of an electrodeposition emulsion, stirring the mixture for a time necessary for the neutralization reaction between the polyimide and the stabilizer to occur to form an intermediate solution, adding a precipitating agent to the intermediate solution while stirring; electrodeposition of the emulsion onto a HTS wire in a cathode cell while the HTS wire is moved through the cell containing the emulsion where the cathode is at a negative potential and the wire is at a positive potential; thermal treatment to form an insulating film on the wire surface by heating at a temperature not exceeding 200° C. A long-length HTS wire with a high-quality thin polyimide insulation coating of a high dielectric strength can be obtained, as well as an insulated HTS strand of a complex shape, e.g., of a Roebel type.
