SC Cable Cooling

SC Cable Cooling


Superconductivity is a phenomenon whereby a charge moves through a material without resistance. In theory this allows electrical energy to be transferred between two points with perfect efficiency, losing nothing to heat. In order to operate superconducting cable, cooling with liquefied Nitrogen is required. The cooling system VACREE designed provides the cooling environment for superconducting cable which is the first one in China. VACREE has a better understanding of cooling technology than any other domestic company in constructing cooling facility.
