China Outdoor high-voltage circuit breaker Manufacturer, Supplier, Factory

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 DJK series Electric energy Metering box is a versatile and reliable solution for electricity metering in high-rise buildings and residential areas. With a maximum current capacity of 63A, it can accommodate a variety of household needs. Additionally, its design can be customized to fit specific requirements, including the number of meter positions and external installation features. This meter box is ideal for households that require accurate and efficient electricity metering.

126KV Outdoor high-voltage SF6 ceramic column circuit breaker is a high-voltage sulfur hexafluoride device used in outdoor electrical systems operating at 126kV. It is designed to manage and safeguard power transmission and transformation networks. This breaker can serve as a switch and disconnection unit when needed. The breaker's innovative arc extinguishing technique involves thermal expansion and auxiliary blowing, and it incorporates a CTB-1 operating mechanism. It complies with the GB1984-2003 standard for AC High Voltage Circuit Breakers and ful specifications of the IEC62271-100:2001 standard for High Voltage Switchgear and Control Equipment Part 100: High Voltage AC Circuit Breakers established by the International Electrotechnical Commission.

This product is designed for 50Hz AC power distribution networks with a rated operational voltage of 380V and a rated current up to 630A. It provides reliable indirect contact protection for personnel and effectively prevents fire hazards caused by ground fault currents resulting from equipment insulation failures. The device incorporates multiple protection mechanisms to deliver precise overload and short-circuit protection for power distribution lines and supply equipment, while featuring circuit status monitoring capabilities. Under normal operating conditions, it can serve as an infrequent switching device for distribution circuits and provide occasional motor starting control functionality. The integrated design combines electrical safety protection with equipment management requirements, significantly enhancing the operational reliability of power distribution systems and fire prevention capabilities.

Our 12KV 4000A indoor vcb lateral type vacuum circuit breaker is specifically designed for integration into switchgear systems, providing dependable and efficient safeguarding of electrical networks operating at a rated voltage of 12kV. Boasting a broad current range of 630A to 4000A, this versatile breaker is adaptable to a diverse array of industrial and commercial environments, making it an ideal solution for a wide spectrum of applications.

In recent years, engineering construction has become increasingly complex as society, the economy, and technology have advanced. There is a growing demand for compact switch equipment that requires minimal maintenance and is intelligent. Domestic and international switch manufacturing companies are actively developing the 35KV 3150A Medium Voltage Gas Insulated Electrical Switchgear, also known as gas-insulated switchgear (C-GIS), which encases high-voltage components like busbars, circuit breakers, isolating switches, and power cables within a pressure-reduced shell.
