    In SF 6 circuit breakers, the same principle is employed, with SF 6 as the medium instead of air. In the “puffer” SF 6 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 SF 6 breakers have been developed for ehv (extra high voltage)
