Introduction
The XGN15-12 AC metal-enclosed ring main unit switchgear uses a sulfur hexafluoride switch as the main switch, with the entire cabinet insulated by air. It is suitable for distribution automation and features a compact and expandable design. It is characterized by its simple structure, flexible operation, reliable interlocking, and easy installation. It can provide satisfactory technical solutions to meet the diverse requirements of different users. Thanks to the adoption of sensor technology and protective circuit breakers, combined with advanced technical performance and a lightweight, flexible assembly solution, it can meet the ever-changing demands of the market.
The main switches of the XGN15-12 AC metal-enclosed ring main unit switchgear include the original ABB SFG type SF6 load switch, FLN series load switches, permanent magnet vacuum circuit breakers, and GE Power/VacVB type vacuum circuit breakers, etc. The operating methods are available in both manual and electric modes.
The XGN15-12 AC metal-enclosed ring main unit switchgear is applicable to power systems of AC 50Hz and 12kv. In industrial and civilian cable interchange points and power supply terminals, it is particularly suitable for the following locations: power distribution in urban residential areas, small secondary substations, switching stations, industrial and mining enterprises, shopping malls, airports, subways, wind power generation, hospitals, stadiums, railways, tunnels, etc.
