The ZW7-36 series 40.5KV 1250A Outdoor high-voltage vacuum circuit breaker is a three-phase, 50Hz AC outdoor switchgear designed for 36 KV power distribution and transmission systems, capable of controlling load currents, overloads, short circuits, and other electrical currents by safely switching them on or off.

The ZN85-40.5/40.5KV Indoor High Voltage Vacuum Circuit Breaker for switchgear, designed for use in AC 50Hz systems with a rated voltage of 40.5kV, is a durable solution for switching load current, overload current, and fault current in industrial and mining facilities, power plants, and substations. Its upper and lower layout structure, reducing its overall depth, is a testament to its durability. The specially designed spring operating mechanism, tailored to suit the upper and lower layout configuration, ensures simplicity, optimal output curve, and performance that aligns with the requirements of 40.5kV vacuum circuit breakers. This circuit breaker's ability to handle frequent operation and its resilience in harsh operating conditions in various environments instill confidence in its durability.

11KV 33KV VCB Vacuum Circuit Breaker designed for three-phase AC 50Hz applications with a rated voltage of 12kV. Suitable for indoor use in various industrial and mining settings, power plants, and substations, it offers reliable control and protection for electrical equipment. Its robust designless installation, either in a switch cabinet or on a handcart, and ensures consistent performance, making it a worthwhile investment for your operations.

The 126KV 1600A Outdoor high-voltage SF6 tank circuit breaker is a sophisticated electrical switching solution designed to safely disconnect high-voltage electrical paths in emergency situations or for regular maintenance. It employs sulfur hexafluoride (SF6) gas as a fire-suppressing and insulating agent, housed within a hermetically sealed container. This particular type of circuit breaker is purpose-built for exterior installation in electrical substations and power distribution systems.

In recent years, the engineering construction industry has faced increasing complexity due to societal and economic growth, as well as rapid technological advancements. As a result, there is a growing demand for more compact and intelligent switch equipment that requires less maintenance. Domestic and international manufacturers are actively developing 40.5KV 1600A High Current High Votage Gis Gas Insulated Switchgear (C-GIS), also known as medium voltage gas-filled cabinets, which enclose high-voltage components like busbars, circuit breakers, isolating switches, and power cables within a pressure-reduced shell..
