The KYN28-12(Z) AC metal-clad switchgear 7.2KV 3150A High Current Medium Voltage Electrical Switchgear is designed for use in three-phase AC power systems operating at a rated voltage of 12kV and a frequency of 50Hz. This equipment is utilized to both receive and distribute electric power while also managing, safeguarding, and overseeing electrical circuits.

In recent years, with the advancement of technology and the growth of society and the economy, engineering construction has become increasingly intricate. There is a rising demand for compact switchgear that is low-maintenance and smart. Both local and global switch manufacturers are currently engaged in the development of 40.5KV 630A Sf6 Sulfur Hexafluoride Filled Gas Insulated Switchgear, which are also referred to as gas-insulated switchgear (C-GIS). This type of switchgear houses high-voltage elements like busbars, circuit breakers, isolating switches, and power cables in a container with reduced gas pressure.

40.5KV 4000A Double-break three post disconnector is designed to enhance the efficiency of indoor stations by reducing the distance and station arrangement. Its robust motor performance resistance is achieved through the electric rod's self-rotation and switching structure, along with its self-locking function. This disconnector is capable of withstanding motor, wind pressure, earthquake, and other external forces. Additionally, its sliding rotation method ensures a strong self-clean ability.
