It is a outdoor high voltage switchgear with three-phase AC 50Hz, which is suitable for the control and protection of 35kV transmission and distribution system, and can also be used for the contact circuit breaker and the opening and closing capacitor bank.
      Besides, it adopts pneumatic arc extinction. The arc time is short and breaking performance is excellent. Under the rated voltage, it can break 31.5kA short-circuit current continuously for 21 times without maintenance and replacing SF6 gas. So this kind of circuit breaker has high mechanical properties, flexible configuration, strong applicability and is easy to use.
