Gas Isolated Switchgear IEC60898,
33kv Ring Main Unit Panel,
SF6 Gas Isolated Switchgear
SF6 ring net cabinet with SF6 load switch as the main switch, for the 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 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, HXGN15 unit type SF6 ring net cabinet can completely meet the requirement of a continuously variable market. It can take self-produced FLBS36 SF6 load break switch; also according to user’s demand can be assembled with the internationally top-ranking VB4 series vacuum circuit breaker with a 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 the permanent magnetic mechanism. Operational methods for the main switch inside the 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.
