Function and Features
Fully insulated, fully sealed, maintenance free, and reliable to ensure personal safety;
Compact structure, volume only 1/3-1/5 of the same capacity European transformer, low height:
A split box structure can be used to avoid oil pollution in the transformer oil tank;
The high-voltage side adopts dual fuse full range protection, greatly reducing costs;
It can be used for ring network or terminal, and the cable head can be urgently plugged and unplugged when the load current is 200A:
The box is made of honeycomb double layered composite board, which has the functions of insulation and heat dissipation;
Install an electronic phase loss protector on the low voltage side, which can quickly disconnect the main switch when abnormal voltage occurs in the system;
High voltage side oil diffusion load switch or SF6 load switch, which can be electrically upgraded, laying the foundation for realizing distribution network automation;
Adopting high-performance oil immersed series transformers.
