SF6 gas under pressure is used as an insulator in gas insulated switchgear (GIS) because it has a much higher dielectric strength than air or dry nitrogen. Medical Use SF6 is used to provide a tamponade or plug of a retinal hole in retinal detachment repair operations in the form of a gas bubble.
[email protected]Gasbanor's SF6-gas treatment and recovery equipment for circuit breakers and gas compartments has provided optimal service around the world for nearly 40 years. Regular servicing of SF6 switchgears and circuit breakers with our equipment can substantially improve their lifetime and performance and helps to cut costs. Features
