Title:
超電導ケーブル
Document Type and Number:
Japanese Patent JP6560733
Kind Code:
B2
Abstract:
To provide a superconductive cable capable of preventing an adiabatic property from degrading, by suitably providing an adiabatic material without loosening on an outer periphery of an inner tube of an adiabatic tube.SOLUTION: A superconductive cable includes: a superconductive cable core having a superconductive wire material; and a dual structure adiabatic tube accommodating the superconductive cable core and having an inner tube and an outer tube, in which the adiabatic tube has a vacuum layer between the inner tube and the outer tube, on an outer periphery of the inner tube, a multilayer adiabatic material formed by laminating a plurality of adiabatic materials is provided, in the plurality of the adiabatic materials, a thickness of the adiabatic material of the outermost layer is thicker than a thickness of the adiabatic material of the innermost layer.SELECTED DRAWING: Figure 3
