sf6 circuit breaker testing MAINTENANCE AND TESTING in Taiwan

About SF6 Circuit Breakers. SF6 electrical circuit breaker is a device where a current is operating with SF6 or Sulphur Hexafluoride being carried on its contacts. It breaks off the power when there's an excessive electricity supply that exceeds the allowed voltage to prevent circuit overload.

    The dielectric strength of sf 6 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.
