<P>PROBLEM TO BE SOLVED: To provide a superconducting power transmission system that prevents damage to a superconducting conductor layer caused by excessive abnormal current without making diameter of a superconducting cable large and that thereby facilitates construction thereof. <P>SOLUTION: A superconducting power transmission system includes a normal temperature insulating type superconducting cable (superconducting cable) 201, a cooling mechanism, and a return pipe 301. The return pipe 301 of the superconducting power transmission system has: a return side heat insulating pipe 33 through which a coolant is passed so as to return to the cooling mechanism; a return side electric insulating layer 43 that surrounds an outer circumference of the return side heat insulating pipe 33; and a shunt conductor 40 that is provided on an inner side of the return side electric insulating layer 43 and that shares abnormal current. <P>COPYRIGHT: (C)2012,JPO&INPIT |
