Superconducting power cable system

A superconducting power cable system, comprising:

• a multi-phase superconducting power cable comprising a cryostat,
• a first cooling station,
• a second cooling station,
• wherein the multi-phase superconducting power cable extends between the first cooling station and the second cooling station,
• wherein the first cooling station is configured to pump cooling fluid into the cryostat in a first direction towards the second cooling station and the second cooling station is configured to pump cooling fluid into the cryostat in a second direction, opposite to the first direction, towards the first cooling station,
• an access pipe assembly arranged between the first cooling station and the second cooling station, the access pipe assembly extending into the cryostat for tapping cooling fluid flowing from the first cooling station and the second cooling station from the cryostat,
• a return pipe structure arranged externally to the multi-phase superconducting power cable, the return pipe structure connecting the access pipe assembly to the first cooling station and to the second cooling station, and providing a respective return cooling fluid line from the cryostat through the access pipe assembly to the first cooling station and to the second cooling station, and
• a first splitter box and a first set of superconducting cable terminations, wherein at a first end of the multi-phase superconducting cable the phases are split up to single phases in the first splitter box and connected to a respective one of the first set of superconducting cable terminations,
• wherein the first cooling station has a first cooling fluid line connected to the first splitter box, supplying cooling fluid to the first splitter box,
• wherein the first splitter box is constructed such that the cooling fluid supplied by the first cooling station via the first cooling fluid line is distributed to a respective cryostat of the single phases leading to the first set of superconducting cable terminations and to the cryostat of the multi-phase superconducting power cable, towards the second cooling station.
