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).
