Product Description
XGN Series High-Voltage Box-Type Fixed-Type
Interchangeable Enclosed Switchgear
I. Product Overview
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 incorporating load switches manufactured by ABB, Areva, or domestic companies.
The product meets the following standards:
GB3906, GB/T11022, GB/T16926, DL/T539, DL/T404
