  • Applications -

    Thanks to its dielelectric strength and excellent insulating properties, SF 6 has been used as an insulating gas for medium and high voltage components for many years. Its excellent arc quenching properties (100 times faster than air) make it suitable as a proven medium in encapsulated medium and high voltage switchgear for decades.

  • GBP £6.55 Testing High Voltage Breakers

    High voltage circuit breakers are extremely important for the function of modern electric power supply systems. The breaker is the active link that ultimately has the role of quickly opening the primary circuit when a fault occurs. Often, the breaker has to perform its duty within a few milliseconds, after months, perhaps years of idly standing by.

  • What is SF6 Circuit Breaker? Construction, Working

    A circuit breaker in which SF6 under pressure gas is used to extinguish the arc is called SF6 circuit breaker. SF6 (sulphur hexafluoride) gas has excellent dielectric, arc quenching, chemical and other physical properties and has proved its superiority over other arc quenching mediums such as oil or air. The SF6 circuit breaker is mainly divided into three types
