one of the main sub-systems of the experimental device, a cryogenic system uses the sub-cooled liquid nitrogen (LN 2) pressurized to cool the HTS cable kicker pro comp 10 and its terminations.This cryogenic system has the sub-cooled LN 2 cycle part and the refrigeration part.The former applies a cryogenic pump to force LN 2 through a heat exchanger in the sub-cooler, the three-phase HTS cable cryostats, and a LN 2 gas-liquid separator.The latter is designed for getting the cooling capacity by decompressing LN 2 to sub-atmosphere, and its maximum cooling capacity is laguna 3hp dust collector about 3.

3 kW and the LN 2 consumed is 72 L/h.
