What is Sulfr hexafluoride Circuit Breaker? - Codrey Electronics

Jul 31, 2020 · July 31, 2020. by Madhu. Sulfr hexafluoride circuit breaker uses insulating gas ( Sulfur Hexafluoride) gas as an air quenching medium. This gas is electro-negative and it has high dielectric strength to absorb free electrons. This is very effective for high voltage applications ranging from 33kV to 800kV. It consists of moving and fixed contacts enclosed in a chamber called an arc interruption chamber filled with Sulfr hexafluoride gas.
