Jul 31, 2020 · July 31, 2020. by Madhu. SF6 circuit breaker uses SF6 ( 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 SF6 gas.
