Product Introduction
1.Product Introduction
HXGN15 - 12 AC metal-enclosed ring network switchgear is a switchgear with sulfur hexafluoride switch as the main switch, and the whole cabinet is insulated by air. It is suitable for power distribution automation, compact and expandable, characterized by simple structure, flexible operation, reliable interlocking and convenient installation. Satisfactory technical solutions can be provided for all kinds of different user requirements. Due to the adoption of sensing technology and protective circuit breakers, advanced technical performance and lightweight and flexible assembly solutions, the HXGN15-12 AC metal-enclosed ring switchgear can meet the changing requirements of the market.The main switches of the HXGN15-12 AC metal-enclosed ring switchgear adopt the original ABB SFG SF6 load switches, FLN series of load switches, permanent mechanical vacuum circuit breakers, GE Power/VacVB vacuum circuit breakers and so on. Vacuum Circuit Breaker, GE Power/VacVB type, and so on. HXGN15-12 AC metal-enclosed ring network switchgear is suitable for AC 50Hz, 12kv power system, widely used in industrial and civil cable switching network and power supply terminal, especially suitable for the following places: power distribution in urban residential areas, small secondary substations, open and close houses, industrial and mining enterprises, shopping malls, airports, subway, wind power, hospitals, stadiums, railways, tunnels and so on. Railroads, tunnels, etc.
