INTERMEDIATE CONNECTING STRUCTURE OF SUPERCONDUCTIVE CABLE POWER TRANSMISSION LINE, AND LAYING METHOD OF SUPERCONDUCTIVE CABLE POWER TRANSMISSION LINE

PROBLEM TO BE SOLVED: To provide an intermediate connecting structure of a superconductive cable power transmission line which is suitable for transmitting a low-voltage power, and can improve the degree of freedom of route design, and a laying method of the superconductive cable power transmission line. SOLUTION: The intermediate connecting structure comprises cable cores 10a, 10b having superconductive bodies, and an intermediate connecting box 3a which connects the ends of the cable cores 10a, 10b. Then, the cable cores 10a, 10b are used for transmitting the low-voltage power. The intermediate connecting box 3a comprises a coolant vessel 30 which is filled with a coolant and accommodates the ends of the cable core 10a, 10b which are connected, and a connecting conductor 50 which is fixed into the coolant vessel 30, and connected with the ends of the cable cores 10a, 10b. Furthermore, the connecting conductor 50 electrically connects the ends of the cable cores 10a, 10b, and the advancing direction of the end of the cable core 10b on a demand side changes with respect to the advancing direction of the end of the cable core 10a on a power supply side via the connecting conductor 50.
