A superconducting power cable system includes a superconducting power cable in a first temperature environment separated from a second temperature environment by a thermal barrier. The first temperature environment is an interior of a cryostat and is at a lower temperature than the second temperature environment located outside of the cryostat. At least one superconducting feeder cable has a first end electrically coupled to the superconducting power cable in the first temperature environment, and a second end electrically coupled to a normal conducting current lead in the second temperature environment. Each superconducting feeder cable is a flexible superconducting cable or wire formed of multiple superconducting tapes that are wound in a helical fashion and in multiple layers around a round former.

When bending a superconducting cable of a stack conductor structure in which a plurality of layers of tape wires are stacked, a twisting process is performed for the superconducting cable immediately before a bending portion of the superconducting cable.
