SUPERCONDUCTING CABLES AND METHOD OF COOLING

摘要

A superconducting cable and method of cooling said superconducting cable is disclosed. The superconducting cable includes a conductor for transmitting electricity, a cryogenic enclosure surrounding the conductor, a coolant return line adapted to return spent coolant for recharging, and an outer insulating sheath encasing the conductor, cryogenic enclosure, and coolant return line to form the superconducting cable. A gap is created between the enclosure and the conductor to allow a coolant to flow therebetween.
