Information

The superconducting cable can show the phenomenon of superconductivity only when it works at a certain low temperature. The cooling system provides the cooling environment for superconducting cable, and the lower the cooling temperature, the stronger the load capacity of cable. The cooling system is mainly composed of liquid Nitrogen pump box, subcooler, high vacuum insulation pipe, liquid Nitrogen storage tank, auxiliary decompression and evacuation system, pump box and gas supply system for pneumatic valves, monitoring system.
