● Fully insulated, fully sealed, maintenance free and reliable to ensure personal safety;
● Compact structure, volume only 1/3-1/5 of European transformer with the same capacity, low height;
● The split box structure can be adopted to avoid oil pollution in the transformer oil tank;
● High voltage side adopts double fuse full range protection, greatly reducing the cost;
● It can be used for ring network or terminal, and the cable head can be plugged and unplugged in an emergency when the load current is 200A;
● The box body adopts honeycomb double sandwich composite board, which has the functions of temperature insulation and heat dissipation;
●The low-voltage side is equipped with an electronic phase failure protector, which can quickly disconnect the main incoming switch when abnormal voltage occurs in the system;
● High voltage side oil immersed load switch or SF6 load switch can be electrically upgraded, laying the foundation for distribution network automation.
