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 reducing 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.
