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. 【課題】超電導ケーブル線路が複数の分岐路で構成される場合、各分岐路における冷媒流路において、冷媒の複雑な流路構成や流量制御を要することなく、超電導ケーブルを適切に冷却できる超電導ケーブル線路を提供する。【解決手段】超電導導体を有する超電導ケーブルと、前記超電導導体を冷却する冷媒の循環路で、一つの基路から分岐される複数の分岐流路を有する冷媒循環路と、前記冷媒循環路に冷媒を供給する供給機構と、前記分岐流路の途中に配置される流路抵抗部とを備え、前記流路抵抗部は、前記分岐流路を、該流路抵抗部に流入する冷媒の流路である往路と、該流路抵抗部から流出する冷媒の流路である復路とに区画し、該流路抵抗部を介して前記往路と前記復路に流れる冷媒流量が冷媒の流通方向に実質的に一様である単位区間を規定する超電導ケーブル線路。【選択図】図１
