The 72.5KV 1600amp Outdoor SF6 high-voltage tank circuit breaker is a unique electrical switch used to disrupt high-voltage electric circuits when faults occur or for regular switching tasks. It relies on sulfur hexafluoride (SF6) gas enclosed in a sealed tank to extinguish arcs and provide insulation. This particular circuit breaker is specially designed for outdoor placement in electrical substations and power distribution systems.

The GW5 outdoor isolation switch is a high-voltage electrical device designed to meet specific structural requirements. It consists of three independent single-phase isolation switches, making it a versatile and reliable option for various applications. The device complies with the standards outlined in the JB520-64 "AC High Voltage Isolation Switch" and features an additional grounding knife device for added safety. The CS-G manual operating mechanism is available in three variations: ungrounded, single-grounded, and double-grounded, providing users with options to suit their needs.

The 11KV 2000amp Vertical break two post isolating switch is a composite-structured 12KV switch designed for outdoor line networks. Equipped with a CS-type operating mechanism, it effectively prevents incorrect operations, such as interlocking with live conductors and composite flash-locks. This negates the necessity for an additional earthline, providing a convenient and efficient solution. Furthermore, the pollution-proof isolating switch is particularly well-suited for use in heavily contaminated areas, effectively addressing shed pollution during operation and ensuring a clean and safe working environment.

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) 7.2KV 1250A Commercial Switchgear Power Distribution Cabinet is designed for three-phase operating at a rated voltage of 12kV and a rated frequency of 50Hz. Its primary function is to manage the reception, distribution, and monitoring of electrical energy as well as to control and protect circuits.

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.
