Product Desciption

General:

SM66unit type SF6 ring net cabinet 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 user. With the adoption of sensor technology and the protection relay up to date, plus the advanced technology and flexible assembly project, SM66 unit type SF6 ring net cabinet can completely meet the requirement of continuously variable market. It can take self-produced RLS-40.5 load switch or SFG type SF6 load switch by ABB; also according to user's demand can be assembled with the internationally top-ranking, RCB series vacuum circuit breaker with permanent magnetic mechanism made by AREVA,or HD4 type SF6 circuit breaker made by AREVA, or HD4 type SF6 circuit breaker made by ABB, or with our VS1-12 type vacuum circuit breaker with permanent magnetic mechanism. Operational methods for the main switch inside ring main unit can be either manual electric power driven. And it can meet the requirement of "four controls" when matched with FTU and RTU.
