Abstract:
1. A method for producing a sheathing around at least one high-T c -superconductor in strip form with an aspect ratio of at least 3, the method comprising: heating the superconductor at least approximately to a process temperature between 200° C. and 500° C. before and during introduction into a guide channel of a die; extruding a melt tube of molten thermoplastic insulating material from the die, the outlet opening of which surrounds the superconductor at a distance on all sides; stretching the melt tube and drawing it onto a surface of the superconductor as the superconductor is advanced outside of the die, wherein a sheathing with an average thickness of less than 100 μm is formed; and setting the melt tube, applied in this way to the surface of the superconductor, by cooling, wherein a thermoplastic material with said process temperature is provided as the insulating material.
