1. This metal clad withdrawable switchgear uses air for insulation, which completely avoids the composite insulation's requirement on environment. Compared with other similar products, our product adapts better to the harsh working environment and has a larger margin of safety.
2. This air insulated switchgear is designed with a true builtin layout, which solves the traditional products' problem of poor handcart interchangeability.
3. The contact strip type primary isolation contact, which has few contact points, big pressure and stable contact performance, is adopted.
4. The active prevention style locking design reflects preventive anti-misoperation performance.
5. Our drawout switchgear is equipped with a 3AF (domestic model ZN12-12) vacuum circuit breaker from German Siemens to match the thermal power units with the power more than 300,000 KW.
6. The combined structure of centralized-stand can be provided.
7. Our withdrawable switchgear can be used in areas with the altitude of 3,000 meters.
8. The switching value required by the integrated protection device is automatically collected.
9. The complete program of 63KA, 4,000A can be realized, thus forming seriation with conventional switch cabinet.
BBE is a professional withdrawable switchgear manufacturer and supplier in China. We offer a variety of products, including withdrawable switchgear, low voltage distribution board, generator circuit breaker, and more.
