    In SF6 circuit breakers, the same principle is employed, with SF6 as the medium instead of air. In the “puffer” SF6 breaker, the motion of the contacts compresses the gas and forces it to flow through an orifice into the neighborhood of the arc. Both types of SF6 breakers have been developed for EHV (extra high voltage) transmission systems.
