China Vacuum circuit breaker for outdoor use Manufacturer, Supplier, Factory

126KV Outdoor high-voltage SF6 circuit breaker is a high-voltage, three-phase AC 50Hz switchgear designed for outdoor use, ideal for controlling and protecting 126kV transmission and transformation systems. Additionally, it can function as a contact breaker and opener group. This circuit breaker utilizes an intelligent arc extinguishing principle that combines thermal expansion with auxiliary blowing, and features a CTB-1 operating mechanism. It meets the standards outlined in GB1984-2003 for AC high-voltage circuit breakers and is compliant with the International Electrotechnical Commission's IEC62271-100:2001 standard for high-voltage AC circuit breakers and control equipment.

The 12KV 2500A High Current Customized Electrical Switchgear KYN28-12(Z) AC metal-clad switchgear is designed for 12kV three-phase AC power systems operating at a frequency of 50Hz. Its primary function is to manage the flow of electricity by receiving, distributing, and overseeing circuits while providing control and protection.

In recent years, with the continuous development of society, economy, and switch technology, the complexity of engineering construction has increased. 40.5KV 3150A Main Transformer Incoming Cabinet High Current High Voltage Switchgears that are miniaturized, maintenance-free, and intelligent for switch equipment are increasingly favored. Domestic and foreign switch manufacturing companies are vigorously developing medium voltage gas-filled cabinets (C-GIS), also known as gas-insulated switchgear. The so-called gas-insulated switchgear refers to sealing high-voltage components such as busbars, circuit breakers, isolating switches, power cables, etc.,inside a shell with lower gas pressure.

The DZ47-63 series miniature circuit breaker is designed for use in lighting and motor distribution systems, protecting against overloads and short circuits. Its innovative design, lightweight construction, and dependable operation make it a high-performance solution.

The 35kv European type Outdoor prefabricated Substation is widely used in urban power grid renovation, residential communities, high-rise buildings, industrial and mining, hotels, shopping malls, airports, railways, oil fields, docks, highways, and temporary electrical facilities, both indoors and outdoors.

The ZW43-12 series 12kv 630A Outdoor Automatical Vacuum Circuit Breaker are designed for outdoor use, with a rated voltage of 12kV and a frequency of 50Hz. These breakers are highly efficient, handling load currents, overload currents, and short circuit currents in power systems with ease. They are particularly suited for substations, industrial and mining establishments, and urban and rural distribution networks, where they provide protection and control, especially in applications that require frequent operation and automation. These breakers comply with several standards, including GB/T1984 for high-voltage AC circuit breakers, GB/T11022 for high-voltage switchgear and control equipment, and D1402 for AC high-voltage circuit breaker ordering technical conditions. Additionally, the circuit breaker can be paired with a controller to form a coordinated device, enabling remote control, monitoring, communication, and adjustment capabilities.
