Title:
THERMAL-INSULATED MULTIPLE PIPE FOR SUPERCONDUCTING POWER TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2018/221522
Kind Code:
A1
Abstract:
Provided is a thermal-insulated multiple pipe for superconducting power transmission having excellent thermal insulation properties and highly suppressing heat incursion from outside caused by radiation, even when not using super insulation. 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 zinc-based coating layer having an average spangle size of no more than 2.0 mm.
