General

HXGN15 series unit type 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.

In recent years, the SF6 ring network cabinet has developed very fast, and both the manufacturing process and the product reliability have the potential to be equal to the international electrical giants. Of course, the voltage level between 24kV and 40.5 still has a certain gap with foreign manufacturers. At present, there are only a handful of domestic manufacturers producing power distribution SF6 power distribution level at 40.5kV level. The others are C-GIS of the first-level system, based on the first-level power system with large current and large capacity. )

Feature
1. Metal-clad and fully enclosed structure, can prevent dirt and small animals from the entrance.
2. Through the observation windows in the door panel switch position and general condition can be clearly viewed.
3. The door and switch operating handle is mechanically interlocked to ensure the door cannot be opened with the switch closed and the switch cannot be closed with the door open.
4. The switchgear use vacuum switches combined with solid insulation material. This environmentally-friendly technology avoid the uses of SF6 as an insulation gas.
5. Reliable FIVE-PREVENTION interlock can effectively prevent from mal-operation.
