SF6 load switchgear GSM
Categories：Secondary distribution network products
Product Profile ：
The GSM-12 series (XGN15-12) indoor AC metal enclosed (unit type sulfur hexafluoride) switchgear and the GSC series indoor SF6 load switch combination device and VSG series vacuum circuit breaker used are developed by our company by introducing advanced foreign technology and combining it with the requirements of the Chinese power system. They have reliable "five protections", anti misoperation functions, and a protection level of IP3X. The main application is particularly suitable for power distribution in urban residential areas, small secondary substations, switch stations, industrial and mining enterprises, large shopping malls, airports, subways, hospitals, sports and other places.

SF6 gas is used as the insulation and arc extinguishing medium, and the constant magnetic field rotary arc extinguishing method ensures that its arc extinguishing ability is not affected by the magnitude of the arc current, with good breaking performance, low overvoltage, long electrical life, and maintenance free arc extinguishing chamber.
Adopting high-quality GSC series indoor SF6 load switches, combination appliances or VSG series vacuum circuit breakers. Equipped with three workstations and multiple functions; Easy to operate, highly reliable operating mechanism and locking mechanism; Equipped with a miniaturized gas pressure gauge. Passed the rated breaking test of SF6 gas zero gauge pressure, with a large functional margin and extremely high reliability.
The grounding switch has short-circuit closing capability that complies with national standards.
