Ⅲ.Features
*Fully insulated, fully sealed, maintenance free and reliable to ensure personal safety;
*The structure is compact, the volume is only 1 / 3-15 of the European variable with the same capacity, and the height is low;
*The box type structure can be adopted to avoid oil pollution in the transformer oil tank;
*The high voltage side adopts double fuse full range protection, which greatly reduces the cost;
*It can be used for ring network or terminal. The cable head can be plugged in and out urgently when the load current is 200A;
*The box body adopts honeycomb double sandwich composite plate, which has the function of temperature insulation and heat dissipation;
*The low-voltage side is equipped with an electronic phase loss protector, which can quickly disconnect the main incoming switch in case of abnormal voltage in the system;
*High voltage side oil immersed load switch or SF6 load switch can be upgraded electrically, laying a foundation for distribution network automation;
*Oil immersed S9 or S11 series transformer with better performance shall be adopted.
