Title: Superconducting cable line

Abstract: A superconducting cable line includes a heat insulation pipe for a fluid for transporting a fluid having a temperature lower than an ordinary temperature and a superconducting cable housed in the heat insulation pipe for a fluid. The superconducting cable including a cable core in a heat insulation pipe for a cable is housed in the heat insulation pipe for a fluid to make a temperature difference between the inside and outside of the heat insulation pipe smaller than that in a situation of laying in an atmosphere. In addition, the superconducting cable has a double heat insulation structure formed with the heat insulation pipe for a cable and the heat insulation pipe for a fluid. Therefore, the superconducting cable line can effectively reduce heat intrusion from the outside into the cable.
