Abstract

The present invention relates to a superconducting cable for reinforcing the physical rigidity of a superconducting wire and, furthermore, for diversifying a distribution path of a fault current so as to reduce the diameter (cross-sectional area) or weight of a former.

Description

technical field [0001] The invention relates to a superconducting cable. More specifically, it relates to a superconducting cable in which the physical strength of a superconducting wire is enhanced to diversify fault current distribution paths, thereby reducing the diameter (cross-sectional area) or weight of a skeleton. Background technique [0002] At a certain temperature, the resistance of the superconducting wire is close to zero, so it also has strong power transmission capability at low voltage. [0003] A superconducting cable including such a superconducting wire is formed and maintained in an extremely low-temperature environment by cooling with a refrigerant such as nitrogen and / or by forming a vacuum layer for heat insulation. [0004] The superconducting wire constituting the existing superconducting cable is wound on a reel in the state of being spirally wound on the outside of the skeleton or the like during the manufacturing process of the superconducting c...
