Abstract

A method involves sheathing a superconductor with a thermoplastic insulation material on all sides. The conductor exits a guide channel that extends in the propulsion direction. A melt hose is extruded from the molten insulation material in the propulsion direction and through a nozzle that has an outlet which embraces the conductor, whereby a distance is kept on all sides. The melt hose is stretched via the propulsion of the conductor. The hose is drawn to the surface of the conductor and is compacted by cooling. The method can especially be used for sheathing band-shaped high-Tc-superconductors. Materials having processing temperatures between 200° C. and 450° C., are selected as thermoplastic insulation materials.
