Title: THERMAL-INSULATED MULTIPLE PIPE FOR SUPERCONDUCTING POWER TRANSMISSION
Abstract:
Provided is a thermal-insulated multiple pipe for superconducting power transmission having excellent thermal insulation properties, having highly suppressed heat incursion from outside caused by radiation, even when not using super insulation, and capable of being easily produced. The thermal-insulated multiple pipe for superconducting power transmission comprises a superconducting cable and a multiplex pipe housing the superconducting cable. The multiplex pipe comprises a plurality of straight pipes. At least one of the plurality of straight pipes has, on the surface thereof, a coating layer containing metal powder.
