Superconducting cable |
摘要 |
A superconducting cable enables the cooling of the superconducting conductor with high efficiency and has a sufficient insulating strength. A method of controlling the temperature of the coolants used in the cable is offered. The superconducting cable comprises a heat-insulated pipe that houses a cable core provided with a superconducting conductor made of a superconducting material. The cable core is also provided with a poorly heat-conductive pipe placed at the outer side of the outer circumference of the superconducting conductor. The inside and outside of the poorly heat-conductive pipe are separately filled with different types of coolants having different purposes. The poorly heat-conductive pipe is filled with a conductor-use coolant for cooling the superconducting conductor so as to maintain it at the superconducting state. The heat-insulated pipe is filled with an insulation-use coolant for performing electric insulation of the superconducting conductor.
