Abstract:
1. Process for the production of a superconducting cable having a single cable care, which contains at least one elongated superconducting element, and a flexible tube, which surrounds the cable core, said process comprising the steps of: (a) continuously pulling the single cable core from a supply unit; (b) continuously pulling a metal strip from a strip supply unit; (c) continuously forming a slotted tube around the cable core with the metal strip to form a slotted tube; welding a longitudinal slot of the slotted tube shut; corrugating the welded tube with the cable core inside the tube, where the inside diameter of the corrugated tube is larger than the outside diameter of the cable core to form a semi-finished superconducting cable; (d) winding the semi-finished superconducting cable in at least one turn on a cable drum; and (e) mechanically joining the ends of the cable core to the ends of the corrugated tube while the cable is on the cable drum.
