The transformer adopts a fully oil-filled sealed structure, and the transformer changes its oil body due to changes in temperature and load, which is completely adjusted by the flexibility of the transformer tank. It has strong lightning resistance and short-circuit resistance. The energy-saving effect is more obvious, and the outer size of the transformer is reduced. 

Product Features:
1.Low noise: compact design structure, application of new materials and new technology, reduce noise, no oil storage tank, lower height than similar products. There is no need to change oil during the normal life, which improves the safety and reliability of power grid operation.
2.Reliable long-term service life: The fully sealed transformer case cover and the tank rim are bolted or welded to isolate the contact between oil and air. The insulation will not be damp, which greatly reduces the insulation aging speed and improves the service life.
3.Small size and beautiful appearance.
4.No hanging core: The user does not need to check the hanging core before the fully sealed transformer is operated, which can save the cost of the hanging core inspection.
5.Maintenance-free: The fully sealed transformer does not require maintenance.
