FIELD: cryogenic engineering. SUBSTANCE: tank car for storing liquid hydrogen is provided with vessel, shell, and combined multi-layered powder insulation between them that is made as alternate layers of insulating and reflecting materials on the vessel and heat insulating powder that fills the clear space. The relationship between the thickness of the insulating layers and reflecting material at a given density of the insulation is defined by the expression presented in the invention description. EFFECT: improved heat insulation. 4 dwg
