  • What is the standard for SF6 gas leakage?-Winfoss

    The indoor space where SF6 high-voltage equipment is installed is generally tightly closed. Once SF6 gas leaks, the toxic decomposition products are deposited in the room and are not easily discharged due to extremely slow air circulation, which poses a great danger to the workers entering the SF6 switch room.
