Sf6 Circuit Breaker Operating Mechanism Flange Connection Screw Sealing Treatment

After installing the sealing ring on the flange face of sf6 circuit breaker operating mechanism, an appropriate sealing material, such as neutral petroleum grease or a similar level of lubricant, must be applied to the outer area that is not in direct contact with SF6 gas.

During the actual installation process, the installation personnel should first thoroughly clean the flange surface, removing metal burrs, rust, oil, and other contaminants to achieve the required smoothness. Subsequently, apply adhesive to the flange bolts and joints, using a product with good adhesion such as 703 sealant, combined with lubricant, to the bolt heads and surrounding surfaces. This aims to improve the compatibility of the mating components and extend the long-term performance of sf6 circuit breaker spring mechanism.
