摘要

Sheathing of a high-temperature superconductor, comprises extruding a melt tube of molten thermoplastic insulation as the conductor leaves a guide channel from a nozzle. The nozzle outlet surrounds the conductor with spacing. As the conductor advances, the tube is extended and drawn down onto its surface. Cooling then sets the plastic. The thermoplastic is processed at 200-500[deg]C.
