Outline

DFW-12 series outdoor high-voltage switchgear is an inflatable outdoor ring network cabinet developed and produced by the company using foreign technology and according to the characteristics of China's regional distribution networks and the actual situation of cable transformation of urban distribution networks.

DFW-12 series outdoor high-voltage switchgear adopts SRM-12/24 series SF6 fully sealed and insulated ring network switchgear, which is modular, scalable, fully insulated, fully sealed, safe and reliable, maintenance-free, etc. It is suitable for any harsh environment and is widely used in industrial parks, residential areas, streets, airports, various buildings, busy commercial

centers and other places.

DFW-12 series outdoor high-voltage switchgear with standard voltage level 12kV and 24kV can extend the distribution network automation function and realize the intelligence of ring network cabinet, making the power grid stronger and wiser.
