FIELD: manufacturing technology.
SUBSTANCE: disclosed is a heat-insulated multi-wall pipe for a superconducting energy transmission system, a heat-insulated multi-wall pipe for a superconducting power transmission system includes a superconducting cable and a multi-wall tube, which contains superconducting cable, where multi-wall pipe is formed of multiple straight pipes, and at least one of multiple straight pipes has on its surface coating layer containing powder metal.
EFFECT: invention provides creation of a pipe, which in high degree prevents inflow of external heat caused by radiation, and demonstrates excellent characteristics of heat insulation without use of super-isolation and can be easily produced.
