Main purpose
1. Fully insulated, fully sealed, maintenance free, and reliable to ensure personal safety;
2. Compact structure, with a volume only 1/3-1/5 of the same capacity European transformer; The height is only 1.5, not blocking the line of sight;
3. Adopting a split box structure to avoid contamination of oil in the transformer oil tank;
4. The high-voltage side adopts dual fuse full range protection, greatly reducing costs;
5. It can be used for both ring network and terminal, and the cable head can be urgently plugged and unplugged when the load current is 200A;
6. The box is made of honeycomb double layered composite board, which has both insulation and heat dissipation functions.
7. The low-voltage side can be equipped with an undervoltage controller, which can quickly cut off the low-voltage side composite when abnormal voltage occurs in the system;
8. High voltage oil immersed load switches or SF6 load switches can be automatically upgraded, laying the foundation for achieving distribution network automation.
purpose
