ZW7-36 series 40.5KV Outdoor ceramic column HV Vacuum Circuit Breaker, a three-phase AC 50Hz outdoor high volt switchgear, is applicable for the 36 KV power distribution and transmission system to close or open the load current, over-load current, short-circuit current and so on.

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 switch equipment that requires less upkeep and possesses intelligent features. Both domestic and international manufacturers are actively developing the 35KV 630A Medium Voltage Inflatable Cabinet Gas Insulated Switchgear (C-GIS) for medium voltage applications, which encloses high-voltage components within a pressure-reduced shell, providing improved performance and reliability.

The 24KV 1250A outdoor sf6 medium voltage circuit breaker is designed for controlling and protecting 24KV transmission and transformation systems, operating at 50Hz and suitable for outdoor use. Additionally, it can function as a connecting circuit breaker and an integrated opening and closing device. This circuit breaker employs an intelligent arc-quenching system based on thermal expansion and auxiliary blowing, paired with a CT10 spring operating mechanism. Furthermore, it meets the standards set by GB/T1984-2014 for AC high-voltage circuit breakers and adheres to the IEC62271-100:2001 international standard for high-voltage AC circuit breakers and control equipment.

The 12KV 3150A Customized Hige Current Eletrical Switchgear is designed for use in three-phase AC power systems with a rated voltage of 12kV and a rated frequency of 50Hz. Its primary function is to receive and distribute electric energy, while also providing control, protection, and monitoring capabilities for electrical circuits.

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.

The European style European style cable junction box cable branch box is a widely used cable engineering equipment in power and distribution network systems in recent years. Its main feature is bidirectional door opening, using through wall sleeves as connecting busbars, with significant advantages such as clear arrangement of small length cables and no need for large span crossing of three core cables. The cable joints used comply with the DIN47636 standard. Generally, a spiral fixed connection cable joint with a rated current of 630a is used
