XGN15-12 BOX-TYPE FIXED A.C. METAL-ENCLOSED SWITCHGEAR
XGN15-12 unit type metal enclosed ring network switchgear is based on FLN□-12 type SF. The load switch is used as the main switch and the entire cabinet adopts air-insulated, compact and expandable metal closed ring network switchgear suitable for distribution automation. It has the characteristics of simple structure, flexible operation, reliable interlocking and convenient installation. We can provide satisfactory technical solutions for various applications and user requirements.
The main switch of the XGN15-12 unit metal enclosed ring network switchgear uses the FLN36-12 and FLN48-12 SF produced by our company. Load switch, or SFG type SF produced by ABB. The load switch can also be equipped with VS1 type, VD4/S type, ISM type vacuum circuit breaker or HD4/S type SF6 circuit breaker according to the user's needs. The load switch and circuit breaker can be operated manually or electrically. The power distribution automation function can be realized after optional electric operating mechanism, PT, CT, FTU and communication device.
