AGN-12/24 SF6 ring main unit with SF6 load switch as the main switch and air insulation for whole cabinet is electric distribution automatization and compact also expandable metal clad switchgear, it character in it's simple strucuture, flexible operation, reliable interlocking and convenient installation etc., which can provide the satisfactory technical projects both for different application occasions and users.
With the adoption of sensor technology and the protection relay up to date, plus the advanced technology and flexible assembly project, AGN-12 unit type SF6 ring main unit can completely meet the requirement of continuously variable market. It can take self-produced AFL-12/24D load break switch or ABB SFG type SF6 load break switch; also according to user's demand can be assembled with the Ukraine BP series vaccum circuit breaker with permanent magnetic mechanism. Operational methods for the main switch inside ring main unit can be either manual or electric power driven. And it can meet the requirement of "Four Controls" when matched with FTU,RTU.
This product conforms to the standards of IEC62271-100 and GB3804,3906.11022, IEC298,265,129,694,420,56,529,932 | |
