PROBLEM TO BE SOLVED: To provide a cable with improved power transmission efficiency, with an installation work made easy, and intrusion of heat reduced. SOLUTION: The superconducting power cable is composed of at least a first pipe 105 housing a coolant passing part 101, a superconducting conductor part 102. and an electric insulation part 103, and a second pipe 106 arranged at outside of the first pipe. A vacuum heat insulation part 104 is formed between the first pipe and the second pipe. The second pipe is made of ferromagnetic material. COPYRIGHT: (C)2006,JPO&NCIPI |
