METHOD OF OPERATING SUPERCONDUCTING CABLE AND SUPERCONDUCTING CABLE SYSTEM

摘要

There is provided a super-conductive cable operation method for performing power transmission by using a conductive material cooled by a coolant. By changing the coolant temperature, it is possible to change the power transmission capacity of the super-conductive cables (110, 120, 130). The super-conductive material can increase the critical current value by reducin g its temperature and accordingly, by changing the coolant temperature, it is possible to change the power transmission capacity without performing an excessive design or additional design of the cable.
