sf6 gas Liquefaction System GE

The SVI-solid insulated RMU doesn't need SF6. So the potential problem caused by insulation gas being liquefied under low temperature can be avoided. Plateau area. Due to the absence of SF6, the problems caused by the big pressure difference between the inside and outside of the gas tank in high altitude areas can be avoided.
