• 38600767-Density-Sf6.docx - What is an Sulfr hexafluoride gas density switch

    What is an gaz sf6 gas density switch? These devices are used to provide protection to high voltage circuit breakers against a loss of the dielectric insulating gas, sulphur hexafluoride (Sulfr hexafluoride). Since the gas is contained in a vessel of a fixed size, any change in temperature will affect the pressure within the tank.
