Features of the 2500kVA Power Distribution Transformer:
1. The 2500kVA transformer has compact structure, low temperature rise and noise, and strong overload capacity. High-quality silicon-steel plates for lower loss.
2. The tank body adopts a corrugated oil tank fully sealed structure to prevent air and water from contacting the transformer, reduce oil aging, and extend the service life of the transformer; the elastic deformation of the corrugated sheet adjusts the volume change of the transformer oil thermal expansion and contraction.
3. The power distribution transformer is an outdoor structure with a high level of anti-pollution; there is no need to replace the transformer oil during the normal use period, and it is maintenance-free, ensuring the safe operation and reliability of the power grid.
4. The transformer is equipped with a pressure release safety protection device. When the transformer fails and the pressure is too high, it can be reliably and safely released through the pressure release valve to prevent the explosion. High-quality rubber sealing material for preventing the transformers from aging or leakage.
