SF6 Decomposition for bid

SF6 Decomposition for bid

Liquid SF6 is allowed to enter a heat exchanger where it is converted to a gas by temperature and pressure dynamics. It is an automatically controlled process. Once the vaporizer switch is turned on and SF6 is allowed to flow from the storage tank, the vaporization system will not allow liquid SF6 to be transferred to the circuit
