ZW32-12FG series outdoor high-voltage vacuum circuit breaker (hereinafter referred to as "circuit breaker") is an outdoor distribution switchgear with rated voltage of 12kW and three-phase AC 50Hz. Circuit breaker is mainly used to open and close the load current, overload current and short circuit current in the power line, with overload and short circuit protection function, to meet the control and measurement requirements, but also to achieve remote control and monitoring functions, widely used in substations, industrial and mining enterprises in the distribution system as control and operation, especially suitable for frequent operation places. Circuit breakers comply with GB1984-2003, DL/T402-2007 and IEC60056 and other technical standards.

ZW32-12 type outdoor column vacuum circuit breaker is a new generation of products developed by our company in response to the new requirements of the State Grid's primary and secondary integration complete sets of column switches. The switch configuration fully meets the requirements of the State Grid's primary and secondary integration complete sets, which facilitates the unified procurement and mass production of the State Grid. The switch structure is compact, the layout is reasonable, the function is complete, and all the indicators meet the requirements of the first and second integration of the State network; The unified parameter protection CT, zero sequence CT and zero sequence voltage sensor has the characteristics of wide measuring range, high measuring accuracy and high reliability, and complete analog quantity is convenient to accurately determine various line faults.

ZW20-12F Primary and secondary fusion outdoor high-voltage vacuum circuit breaker for rated voltage 12kV, three-phase AC 50Hz outdoor distribution equipment. It adopts vacuum arc extinguishing and SF6 gas as the insulating medium, and is an improved product of ZW20-12F type column vacuum circuit breaker. The box adopts the gas sealing, explosion-proof and insulation structure technology introduced by Toshiba VSP5, and the sealing performance of the inlet and outlet pipe is also improved. The overall sealing performance is excellent, and the SF6 gas filled inside is not leaked and is not affected by the boundary environment. Its spring operating mechanism has been miniaturized design and reliability and stability optimization, using direct chain main transmission and multistage tripping system, the operating reliability and stability are several times higher than the traditional spring operating mechanism in China; The contact between the shaft and the sleeve of the main loop adopts the

ZW32C-12 Outdoor high voltage vacuum circuit breaker/deep fusion uses vacuum arc extinguishing principle, permanent magnet operating mechanism (bomb operating mechanism), integrated micro-processing technology, modern network communication technology and new switch manufacturing materials in one. The rated voltage is 12kV,50Hz three-phase AC outdoor distribution equipment. The product is widely used in urban power grid as a break or contact switch, or used in rural power distribution system. The outdoor substation outlet switch can effectively complete the work of the traditional recloser, dividing and combining the load current and short circuit current.

ZWJ-12 power load control metering box (hereinafter referred to as metering box), mainly used for rated voltage 10kV, rated frequency 50Hz, capacity 5000kVA and below power users and substation area, play the role of load control, high voltage electric energy metering. With the load control terminal or other controllers can achieve load control, high voltage metering, high voltage prepaid, overload current protection, anti-theft and other functions.

ZW32-12M permanent magnet outdoor vacuum circuit breaker (hereinafter referred to as circuit breaker) is an outdoor distribution equipment with rated voltage of 12kV and three-phase AC of 50Hz. It is mainly used to break and close the load current, overload current and short circuit current in the power system. It is suitable for protection and control in power distribution systems of substations and industrial and mining enterprises, and places where rural power grids are frequently operated. The circuit breaker has the characteristics of small volume, light weight, anti-condensation, maintenance-free, etc., and can adapt to harsh climatic conditions and dirty environment.
