VS1-12 Side-Mount Indoor High-Voltage AC Vacuum Circuit Breaker
The VS1 (ZN63A) side-mounted indoor high-voltage vacuum circuit breaker (hereinafter referred to as the circuit breaker) is an indoor switchgear device used in 12kV power systems, serving as a protection and control unit for grid equipment and power equipment in industrial and mining enterprises. Thanks to the unique advantages of vacuum circuit breakers, they are particularly well suited for applications that require frequent operation at rated working current or for circuits that need to interrupt short-circuit currents multiple times. The circuit breaker features an integrated design that combines the operating mechanism with the circuit breaker body, functioning as a fixed installation unit; moreover, fixed-type circuit breakers can be equipped with corresponding interlocks to meet the requirements of fixed switchgear such as HXGN cabinets.
VS1-40.5 Indoor High-Voltage Vacuum Circuit Breaker – Insulating Cylinder
This product is suitable for indoor high-voltage equipment with a rated voltage of 40.5 kV and a three-phase AC frequency of 50 Hz. It can be used by industrial and mining enterprises, power plants, and substations to switch load currents, overload currents, and short-circuit currents, and is also appropriate for applications involving frequent operations.
VS1-40.5E Indoor High-Voltage Vacuum Circuit Breaker – Solid-Encapsulated Pole
VS1-40.5 Indoor High-Voltage Vacuum Circuit Breaker is designed for indoor switchgear in 50 Hz, 40.5 kV AC power systems, serving as a protection and control unit for grid equipment and power equipment in industrial and mining enterprises. It is suitable for applications involving frequent operations at rated working current or for multiple short-circuit current interruptions.
ZW32-12 Series Pole-Mounted Circuit Breakers
The ZW32-12 indoor high-voltage vacuum circuit breaker, also known as an indoor pole-mounted vacuum circuit breaker, can switch and interrupt load current, overload current, and short-circuit current in power systems. It can be used directly for switching operations on 10kV equipment, and it can also be employed at sectionalizing points along 10kV distribution lines to ensure rapid isolation and removal of faults within that section.
ZW20-12/T Series Pole-Mounted Circuit Breakers
The product consists of three main components: the circuit breaker body, the operating mechanism, and the lifting device.
Circuit Breaker Body Structure: The circuit breaker body is composed of a conductive circuit, an insulation system, sealing elements, and a housing. The entire conductive circuit is formed by connecting the incoming and outgoing busbars, current-carrying contacts, flexible connectors, and the vacuum arc extinguishing chamber.
This product employs SF6 gas insulation. The incoming and outgoing line insulating bushings are made of epoxy resin and silicone rubber through integral casting. To reduce the switch’s footprint while maintaining adequate phase-to-phase insulation clearance, corner bushings are used for phases A and C, ensuring reliable external insulation. Internally, a composite insulation structure is adopted, enabling the product to achieve the required insulation levels even without SF6 gas filling.
LW3-12 Series SF6 Outdoor High-Voltage Circuit Breaker (Primary and Secondary Integration Circuit Breaker)
The LW3-12 pole-mounted circuit breaker is suitable for three-phase power systems with AC 50/60 Hz and a rated voltage of 12 kV, used to switch load currents, overload currents, and short-circuit currents. It can automatically isolate the section of the distribution line where a fault has occurred. The switch is equipped with a new‑technology electronic controller that supports manual operation, motorized operation, and remote operation. The electronic controller is designed to operate under a wide range of climatic conditions and enables remote monitoring and control. Installation and configuration are convenient, reliable, and fast, helping to reduce construction costs.
