SF6 Breakers Maintance Safe and efficient

Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay.Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit.Advantages over other media include lower operating noise and no emission ...

  • The Importance of SF6 Circuit Breaker Testing and Maintenance

    Jul 18, 2018The SF6 is what helps cut off the power when there’s an overload. An SF6 Circuit Breaker also boasts a very high level of electro-negativity, which means it also has a high absorption capacity for free electrons. When these electrons collide with the SF6 molecules, they get absorbed immediately and turned into negative ions, which weigh more.
