Abstract
A process is provided for the production of a superconducting cable having a single cable core that contains at least one elongated superconducting element and a flexible tube that which surrounds the cable core. The process includes continuously pulling the single cable core from a supply unit, continuously pulling a metal strip from a strip supply unit and continuously forming a slotted tube around the cable care with the metal strip to form a slotted tube. The longitudinal slot of the slotted tube is welded shut corrugating the welded tube with the cable core inside the tube. The then semi-finished superconducting cable is wound in at least one turn on a cable drum, and the ends of the cable core are mechanically joined to the ends of the corrugated tube while the cable is on the cable drum.
