HEAT-INSULATED MULTILAYER PIPE FOR ELECTRIC POWER TRANSMISSION UNDER CONDITIONS OF SUPERCONDUCTIVITY Russian patent published in 2020 - IPC H01B12/14 H01L39/04 

Abstract RU 2719767 C1

FIELD: heat insulation.

SUBSTANCE: disclosed is a heat-insulated multilayer pipe for transmitting electric power in superconductivity conditions, which highly prevents penetration of external heat as a result of radiation and has excellent heat-insulating properties without using super-high-power insulation. Heat-insulated multilayer pipe for electric power transmission in conditions of superconductivity contains superconducting cable and multilayer pipe, in which a superconducting cable is placed, wherein the multilayer pipe consists of a plurality of straight-line tubes and at least one of the plurality of straight-line pipes comprises a zinc or zinc alloy coating layer having an average spangle size of 2.0 mm or less.

EFFECT: invention substantially prevents penetration of external heat as a result of radiation and has excellent heat-insulating properties without using super-heavy insulation.
