During the use of high voltage equipment, the parameters of SF6 insulating gas will change with the change of service time and environment.

Under the action of high power arc, spark discharge and corona discharge, SF6 gas can decompose a variety of products. In addition, a small amount of impurities, such as air, water and mineral oil, may be mixed in the gas filling process. Containing or likely to produce certain toxic substances.

Our company’s vehicles are all in one service vehicle, including SF6 gas leakage monitoring (real-time monitoring of any leakage during filling), SF6 gas comprehensive analyzer (SF6 gas purity, humidity and several decomposition products measurement), vacuum pumping equipment (after the air in the evacuation equipment contacts with the air), heating and re charging equipment (equipment flushing fresh gas cylinders), It is equipped with SF6 recovery and purification device (which can realize the recovery and reuse of SF6 gas and return to high-pressure equipment for purification after filtration). It is a complete set of gas treatment equipment. After arriving at the site, it can process SF6 gas in one stop and meet the IEC standard.

Inject SF6 gas back into the equipment for reuse. Economy, environmental protection and reliability.

Advantages of service car:

Minimize waste disposal costs

The cost of new SF6 gas is reduced

Reduction of transportation expenses

Reduce storage costs

The purity of the prepared SF6 gas fully conforms to IEC 60480 “standard for SF6 gas for industrial use”. Value gained

humidity

SF6 gas volume

Decomposition products (sulfur dioxide)

It is far lower than the reference value of IEC 60480 directive, even lower than the values specified in IEC 60376 (provisions for new SF6 gas) and GB / T 12022 / 2006 (Chinese standard for new SF6 gas).

You can find an overview of the IEC standard for SF6 gas here.
