Series outdoor communication High-voltage vacuum circuit breaker is a three-phase AC outdoor high-voltage switchgear. It is mainly used in rural power grids and urban power grids for switching load current, overload current and short-circuit current. It can also be used in other similar places. Product Features * It adopts ceramic vacuum arc chamber with strong arc-extinguishing ability, high number of short-circuit openings and no dangers such as fire and explosion, and does not pollute the environment. *The electric spring operating mechanism can be operated manually or electrically, which is very convenient and reliable. It can be connected to remote operations to achieve three remote operations. *The overall structure adopts a three-phase common box structure with dry air inside the casing inlet and outlet box, which can be used reliably under harsh environmental conditions. *This product is equipped with multiple functions such as overcurrent protection, zero sequence protection, reclosing, low voltage and overvoltage protection. *This product is small in size, light in weight, beautiful in appearance, compact in design, and the incoming and outgoing conductive rods are injected with silicone rubber and have good anti-pollution properties. *This product can be installed with an isolated knife gate for maintenance lines. It has obvious visible fractures to enhance safety. *An interlocking device is installed between the isolation knife switch and the circuit breaker.
