Overview
1. Fully insulated, fully sealed, maintenance-free, and reliable to ensure personal safety.
2. Compact structure, volume only 1/3-1/5 of the equivalent European type; height is only 1.5, does not block the line of sight.
3. Adopts a compartmentalized structure to avoid contamination of the transformer oil tank.
4. The high-voltage side adopts dual fuse full-range protection, greatly reducing costs.
5. Can be used for both ring network and terminal; cable heads can be emergency plugged and unplugged at 200A load current.
6. The cabinet adopts a honeycomb-type double-layer composite board，which has the functions of thermal insulation and heat dissipation. This technology is the latest patent developed by the company.
7. The low-voltage side can be equipped with undervoltage controller. When abnormal voltage occurs in the system, the low-voltage side load can be quickly cut off.
8. The high-voltage side uses oil-immersed load switches or SF6 load switches, which can be automatically upgraded, laying the foundation for achieving distribution network automation.
