SUPERCONDUCTIVE CABLE LINE

摘要

A superconducting cable line includes a heat insulation pipe for a fluid (2) for transporting a fluid (1) having a temperature lower than an ordinary temperature and a superconducting cable (10) housed in the heat insulation pipe for a fluid (2). The superconducting cable (10) including a cable core in a heat insulation pipe for a cable is housed in the heat insulation pipe for a fluid (2) 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 (10) has a double heat insulation structure formed with the heat insulation pipe for a cable and the heat insulation pipe for a fluid (2). Therefore, the superconducting cable line can effectively reduce heat intrusion from the outside into the cable.
