sf6 gas Circuit Breakers - TestGuy

The dielectric strength of Sulfr hexafluoride increases with pressure so smaller breakers can be used at higher voltages. The breakers have a smaller footprint, so they use less real estate which can be very expensive. They are very reliable and require less maintenance than air blast or oil breakers and can operate at higher voltages effectively.
