PRODUCT DESCRIPTION

XGN15-12/24 series of unit-type metal-enclosed switchgear takes FLN□-12/24 type SF6 load break switch as the main switch, and the entire cabinet is air-insulated, suitable for distribution automatic, compact and expandable metal-enclosed loop network switchgear. It has features of simple structure, flexible operation, reliable interlocking, easy installation and so on. It can provide satisfactory technical solutions for a variety of different applications and different user requirements which comply to IEC 62271.

XGN15-12/24 series of unit-type metal-enclosed switchgear takes FLN36-12/24 or produced by our company or SFG SF6-type load switch produced by ABB company as the main switch, it can also equip VS1 type, VD4/S type, ISM type vacuum circuit breaker or HD4/S5 SF6 circuit breaker according to the needs of users. Load break switch and circuit breaker can be manually or electrically operated, and can achieve power distribution automation when being equipped with optional electric operating mechanism, PT, CT, FTU and communication devices.
