The advancement of society, economy, and technology has led to increased complexity in engineering construction. There is a growing demand for compact, low-maintenance, and intelligent switch products. Both domestic and foreign switch manufacturers are actively developing 12KV 1600A Medium Voltage Gas Insulated Electrical Switchgear (C-GIS), also known as gas-insulated switchgear. Gas-insulated switchgear refers to the encapsulation of high-voltage components, such as busbars, circuit breakers, isolating switches, and power cables, within a shell that maintains a lower gas pressure.

The 72.5KV Outdoor high-voltage SF6 ceramic column circuit breaker is designed for controlling and protecting 72.5KV transmission and transformation systems. It operates on a three-phase AC 50HZ outdoor high-voltage switchgear and can function and opener group. By utilizing the intelligent arc extinguishing principle of "thermal expansion+auxiliary blowing" and equipped with a CTB-1 operating mechanism, this circuit breaker meets the standards of GB1984-2003 and International Electrotechnical Commission standard IEC62271-100:2001 for High Voltage AC Circuit Breakers.

The KYN28-12(Z) 3.6KV 630A Medium Voltage Electrical Switchgear is designed for 12kV rated voltage and 50Hz rated frequency in three-phase AC power systems. It functions to handle electric energy reception and distribution, as well as to control, protect, and monitor circuits.

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.

In recent years, the field of engineering construction has faced increasing complexity due to advancements in technology and the growth of society and the economy. There is a rising demand for compact switch equipment that is smart and requires minimal maintenance. Both local and global manufacturers of switches are currently focusing on the development of 12KV 2500A Sf6 Sulfur Hexafluoride Infiilled Electrical Switchgear, also referred to as gas-insulated switchgear (C-GIS). These C-GIS systems encase high-voltage components like busbars, circuit breakers, isolating switches, and power cables in a housing with reduced gas pressure.

The Drawer type low-voltage switchgear ensures that each functional unit is distinct from the busbar or cable, creating three separate areas for efficient power distribution. This design also incorporates isolation measures between functional units, contributing to the overall reliability and safety of the switchgear. As a result, drawer-type switchgear is widely used in industrial and mining enterprises, high-rise buildings, and centralized control distribution centers that require high power supply reliability. The switchgear's closed steel plate shell houses withdrawable drawers containing electrical components for incoming and outgoing circuits, allowing for easy maintenance and customization.
