It is used to disconnect and close load current. It has overload and short-circuit protection functions, quick-break protection function, time-limited delay protection function, automatic reclosing function, and can also be equipped with lightning arrester or disconnector (i.e. circuit breaker and disconnector combination, hereinafter referred to as "combined intelligent circuit breaker") according to user needs. The intelligent circuit breaker has its own power supply and can be remotely controlled nearby. It is equipped with CT and PT interfaces to meet telemetry requirements.

Three phase AC system (50Hz, 10-12kV), load current switching, overload and short circuit protection. Fast breaking protection+time limited delay protection, automatic reclosing function, optional lightning arrester or isolation switch (combination intelligent circuit breaker), built-in operating power supply, supports near/remote control, equipped with CT/PT interface, meets telemetry requirements

ZW43A-12F outdoor vacuum circuit breaker is used to make and break load current, overload current and short-circuit cur rent in 12kV, AC 50/60Hz power system. It is applicable for substations, industry and mining, urban and rural electricity power networks, especially for occasions with frequent operation and automatic power distribution network.

ZW20-12F/T□ -□ series outdoor high voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is an outdoor power distribution equipment with a rated voltage of 12kV and three-phase AC 50Hz. It uses vacuum arc extinguishing and SF6 gas as the insulating medium and is an improved product of ZW20-12F pole mounted vacuum circuit breaker.

ZW20-12/T□-□ series outdoor high-voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is an outdoor power distribution equipment with a rated voltage of 12kV and three-phase AC 50Hz. It uses vacuum arc extinguishing and SF6 gas as the insulating medium,a nd is an improved product of ZW20-12F type pole-mounted vacuum circuit breaker. The box adopts VSP5's gas sealing, explosion-proof and insulation structure technology, and the sealing performance of the inlet and outlet line ducts has also been improved. The overall sealing performance is excellent, and the SF6 gas filled inside does not leak and is not affected by the external environment; its spring operating mechanism has been miniaturized and optimized for reliability and stability, and adopts a direct-acting chain main drive and a multi-stage tripping system. The action reliability and stability are several times higher than that of the traditional domestic spring operating mechanism; the contact between the shaft and the sleeve of the main circuit adopts an inward-retracted and outward-stretched watch chain structure, and the contact resistance of the main circuit is small and the temperature rise is low. Therefore, ZW20-12F type outdoor pole-mounted vacuum circuit breaker is a maintenance-free product and a top-quality pole-mounted circuit breaker.

ZW20-12 circuit breaker, 12kV vacuum switch, rural grid protection, outdoor HV breaker，Special design for rural power grid: in line with the requirements of national grid standardization transformation Advantages of column installation: Weight<120kg, space saving for single pole installation Anti theft structure: fully sealed design+dedicated lead seal hole position

The floor-standing demarcation switch integrated prepaid metering device is a product that changes the column-mounted high-voltage metering, switch, and control box into a cabinet-type structure. It is composed of an integrally cast dry-type high-voltage metering box and a ZW32F type intelligent demarcation switch. The box is made of stainless steel or iron plate sprayed plastic. This product is easy to install in structure and has a beautiful appearance. The high-voltage part is isolated from the low-voltage meter room, and the high-voltage room cannot be opened for operation when the equipment is energized. The high-voltage room door can only be opened in the event of a power outage, which is safe and reliable. The product occupies a small area and is a combination product used in living areas, industrial and mining enterprises and box-type transformers.
