PRODUCTS CENTER
The product is suitable for three-phase AC distribution systems ranging from 3 to 24 kV, 50 Hz, and serves as a ring network power supply unit and terminal equipment—specifically, a complete set of high-voltage AC switchgear. It is primarily designed for supplying power at the terminals of 12/24 kV three-phase ring networks or radial grid systems. The device is capable of interrupting load currents and short-circuit currents, as well as making and breaking short-circuit currents. The vacuum load switch used in this system is manufactured by a domestic company.
This product series comprises complete sets of AC high-voltage electrical equipment rated for voltages between 12 and 40.5 kV and operating at a frequency of 50 Hz. Primarily designed for use in 12–40.5 kV power supply and distribution systems—including secondary substations, switchgear stations, industrial and mining enterprises, urban residential complexes, airports, railways, tunnels, and high-rise buildings—the equipment serves as critical components for transmitting and distributing electrical energy. Additionally, these compact yet expandable, metal-enclosed switchgear units are widely employed in both commercial and industrial applications, as well as in automated distribution systems, offering both space efficiency and scalability.
This product series consists of complete sets of AC high-voltage electrical equipment rated for 12 (24) kV and 50 Hz, primarily designed for use in 12–24 kV power supply and distribution systems—including secondary substations, switchgear stations, industrial and mining enterprises, urban residential complexes, airports, railways, tunnels, and high-rise buildings—as well as for transmitting and distributing electrical energy. These devices are also widely employed in civil applications, industrial settings, and distribution automation systems. They feature compact yet expandable metal-enclosed switchgear, with SF6 ring main unit load switchgear utilizing either ABB or Areva components, alongside domestically produced load switches.
Introduction to the KYN28 Enclosed Metal-Clad Switchgear The KYN28 (Z) series of high-voltage, enclosed, metal-clad switchgear is a complete distribution device designed for 3.6 to 40.5 kV, three-phase, 50 Hz AC power systems. It is primarily used in single-bus and single-bus sectionalized configurations in power plants, substations, and distribution centers within the power grid. This equipment serves key functions such as receiving and distributing electrical power, as well as providing power distribution for industrial, mining, and commercial enterprises, and facilitating the starting of large high-voltage motors. Additionally, it enables precise control, monitoring, and protection of electrical circuits.
