Product Overview:
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. This technology belongs to our company's latest developed patent.
7. An undervoltage controller can be installed on the low voltage side, which can quickly cut off the load on the low voltage side 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.
