Abstract

A method of cooling at least one superconductive cable is disclosed which is arranged in a cryostat having at least one thermally insulated pipe with a free space surrounded by the pipe, wherein the cable and at least one tubular structure are arranged in the free space, and wherein a cooling agent is conducted through the free space from a feeding point located at one end to a distal end. The cooling agent is conducted through the cryostat and the tubular structure exclusively in one direction of the cable until it reaches its temperature of operation and is discharged to the outside at the distal end. After reaching the temperature of operation, the cooling agent is returned from the distal end of the arrangement through the tubular structure to the feeding point.
