Rectangular Transformer Tanks

Product Introduction

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.
