Instructions For Applying Polytetrafluoroethylene Grease To The Sealing Parts Of The Sf6 Circuit Breaker Operating Mechanism

In the maintenance process of sf6 circuit breaker operating mechanism, a thin layer of HL#10 PTFE grease is applied to the surfaces of certain metal parts and seals that come into contact with SF6 gas.

This grease forms a stable interfacial film between the metal and the seals, helping to maintain the flexibility of the mechanism's opening and closing actions. Even when the equipment is stationary for extended periods, it maintains sealing performance and smooth movement. Simultaneously, PTFE itself has a low coefficient of friction and good corrosion resistance, providing reliable adaptability to high-pressure SF6 environments.

For sf6 circuit breaker spring mechanism, lubrication is closely related to sealing. Even application of grease ensures proper lubrication between the seals and related sliding parts, reducing the risk of mechanical jamming or damage due to dryness. Practical experience has also shown that mechanisms treated in this way maintain relatively stable operating speeds and reliability during repeated opening and closing operations.
