Method of cooling a superconductive cable

Method of cooling at least one superconductive cable, where the cable is arranged in a cryostat having at least one thermally insulated pipe, with the cryostat having a free space surrounded by the pipe, where the cable and at least one tubular structure are arranged in the free space of the cryostat, and where a cooling agent is conducted from a feeding point located at one end up to a distal end of the cryostat, said method comprising the steps of:

• that the cooling agent is conducted until the cable is cooled to its temperature of operation exclusively in one direction through the cryostat and the tubular structure and is discharged to the outside at the distal end, and
• that the cooling agent is returned after reaching the temperature of operation from the distal end of the arrangement through the tubular structure to the feeding point.
