procedures for the isolation of a superconductor, in particular with oxidischem high - t c? - supraleitermaterial, and use of the procedure

摘要

Method whereby a superconductor (5) is enclosed on all sides with a thermoplastic insulating material. The conductor (5) emerges from a guide channel (3) that extends in a forward direction (v), a fused flexible tube made of molten insulating material (6) is extruded from a nozzle (2) in a forward direction, whereby the outlet (8) thereof surrounds the conductor (5) at a distance on all sides, and the fused flexible tube (9) is extended while the conductor (5) moves forward, is drawn onto the surface of the conductor and is compacted as it cools down. The inventive method can be especially used to enclose strip-like high Tc superconductors.
