Abstract
A method is provided for manufacturing a superconductive cable equipped with means for compensating length changes caused by temperature changes which occur when the cable is cooled from room temperature to work temperature and vice-versa. A superconductive cable (SK) with a tubular, central carrier (1) is used which is surrounded by at least one superconductive conductor. Arranged in the carrier (1) is at least one tension-proof strand (2) arranged over the entire length of the carrier (1). Cable (SK) is initially wound, including strand (2), at room temperature onto a coil (SP). Subsequently, the strand (2) is immovably fastened to the two ends of the cable (SK) and the cable (SK) is subsequently wound off the coil (SP).

Method of manufacturing a superconductive cable equipped with means for compensating the length changes which are created when the cable is cooled from room temperature to work temperature and vice-versa, and where the superconductive cable having a tubular central carrier which is surrounded by at least one superconductive conductor, and where at least one tension proof strand is in the carrier, arranged over the entire length thereof, said method comprising the steps of:
- the cable, together with the strand, is initially wound onto a coil at room temperature;
- the strand is subsequently immovably secured to both ends of the cable while said cable and strand are still wound on said coil said strand thereby making contact with the inner surface of the carrier;
- and
- the cable is then wound off the coil.
