A superconducting power cable system, including: a superconducting power cable including a cryostat, a first cooling station, a second cooling station, wherein the 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, and a return pipe structure arranged externally to the 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.

Superconducting power cable system

A superconducting power cable having: a former including: an axially stretchable core, and a plurality of elongated outer elements wound helically around the core, wherein the core includes a first material and the elongated outer elements include a second material thermally contracting less than the first material at the operating temperature of the superconducting power cable; and a superconducting conductor layer arranged around the former.
