XGN15 AC metal enclosed ring network switchgear
PRODUCT DETAILS
XGN15 series box-type fixed AC metal-enclosed switchgear is a compact and expandable metal-enclosed ring that uses FLN-12 SF6 load switch as the main switch and the whole cabinet adopts air-insulated, suitable for distribution automation. network switchgear it has the characteristics of simple structure, flexible operation, reliable interlocking and convenient installation. lt can provide satisfactory technical solutions for various applications and different user requirements.
The main switch of XGN15 series box-type fixed AC metal-enclosed switchgear adopts the FLN36-12 type, FLN48-12 type SF6 load switch produced by our company, or the SFG type SF6 load switch produced by ABB company. lt needs to be equipped with VS1 type.VD4/S type, ISM type vacuum circuit breaker or HD4/55 type SF6 circuit breaker. The loads witch and circuit breaker can be operated manually or electrically, and the power distribution automation function can be realized after selecting the electric operating mechanism, PT,CT,FTU and communication device.
