Product Description
12kv Sf6 Ring Main Unit Switchgear GSM
GSM-12/24 unit type SF6 RMU with SF6 load switch as main switch, for whole cabinet is suitable for electric distribution automation and compact also expandable metal close switchgear. It characters in its simple structure, 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, GSM-12/24 unit type SF6 RMU can completely meet the requirement of continuously variable market. It can take self-produced GSC-12/24 load break switch; also according to user's demand can be assembled with the internationally top- ranking series vacuum circuit breaker with permanent magnetic mechanism made by famous brand SF6 circuit breaker. 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 and RTU.
