Problems solved by technology

[0010] When absorbing radiant heat energy per unit length of 3W / m or more as described above, the capacity of the cooling system of the superconducting cable must be increased, which results in a decrease in efficiency and an increase in load
[0011] In addition, it is necessary to increase the thickness of the heat insulating layer, thus increasing the cost due to the increased need of the heat insulating layer, so there are problems in that due to the increase in the thickness of the heat insulating layer, the space kept under vacuum decreases and the diameter of the spacer decreases.

Abstract

Provided is a superconducting cable with aluminum cryostat configured to improve superconductivity by increasing reflectivity of cryostats and enhancing cooling performance. The superconducting cable includes: a core provided with a conductor; and a cryostat surrounding a periphery of the core. A material of the cryostat is aluminum or an aluminum alloy and a surface roughness of the cryostat is 30 microns or less in terms of RMS value.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119 and all benefits arising from Korean Patent Application No. 10-2010-16631 filed on February 24, 2010, the contents of which are All are incorporated herein by reference. technical field [0003] The present disclosure relates to a superconducting cable, and more particularly, to a superconducting cable configured to improve superconductivity by increasing reflectivity of a cryostat and enhancing cooling effect. Background technique [0004] In a superconducting cable that can transmit more electricity with very little loss than existing power cables, a cryostat used to keep the temperature very low to keep the superconducting wire in a superconducting state surrounds the superconducting cable core . [0005] figure 1 is a conceptual diagram showing a longitudinal section of a superconducting cable according to the related art. [0006] Such as figure 1 As shown...
