<p>PROBLEM TO BE SOLVED: To provide a superconductive cable line which can cool a superconductive cable appropriately without a complicated passage configuration for or control of the flow rate of the coolant, in a coolant passage in individual branched lines, when the superconductive cable line consists of a plurality of branched lines.SOLUTION: A superconductive cable line includes a superconductive cable having a superconductive conductor, a coolant circulation path which is for a coolant cooling the superconductive conductor and has a plurality of branched passages branched from a base path, a supply mechanism supplying the coolant to the coolant circulation path and a passage resistance part arranged in the middle of the branched passages. The passage resistance part divides the branched passage into an outward path serving as a passage for the coolant flowing into the passage resistance part and a return path serving as a passage for the coolant flowing out of the passage resistance part, and there is specified a unit section in which the flow rate of the coolant flowing in the outward path or the return path through the passage resistance part is practically uniform in the flowing direction of the coolant.</p> |
