  A cryogenic Joule-Thomson (JT) refrigerator has a lot of advantages for large industrial application,such as cooling power adjustability and high reliability.In this paper,single and dual-stage of non-flammable (NF) mixed refrigerant (MR) JT refrigeration cycle has been suggested for precooling circuit of high temperature superconductor (HTS) electric power cable below 100 K.
