On the high-voltage power load switches,circuit breakers, power transformers in the SFGas,leak-free recycling, purification filter,liquid storage or return Filling ,recycling.
Testing equipment,direct recovery from the SF6 gas in the liquid storage tank
SF6 equipment can use a vacuum
External culinder,the Sf6gas charge to the device
Through the recycling of Sf6 gas purifying filter,liquid dried to charge the mainternance of equipment or fkuid storage container
SF6 gas production for direct filling
