AGi-12 series environmentally friendly gas insulated ring network is a fully insulated, green intelligent ring network switchgear independently developed with intelligent design concept. AGi-12 series environmentally friendly gas insulated ring network cabinet has the characteristics of full insulation, long life, maintenance-free, small space occupation, safety and reliability, and no environmental impact. It is widely used in industrial and civil ring networks and terminal power supply. It is particularly suitable for small secondary distribution stations, switchgear, industrial and mining enterprises, airports, railways, commercial areas, high-rise buildings, highways, subways, tunnels and other fields. Especially in special environments such as plateaus, humidity, coldness, and low-lying areas.
The launch of the AGi-12 series of environmentally friendly gas-insulated ring main unit switchgear truly and fully meets the needs of customers such as the State Grid Corporation of China and China Southern Power Grid Corporation for environmentally friendly ring main unit cabinets.
