oil-immersed transformer

Fully sealed product,no oil conservator,lowers than similar product.It is used vacuum impregnating oil techniques;fully take off the humidity in oil box.It is non-contact with oil and air completely.It is no need to do oil sample test regularly.

Good insulation and high level impacting lighting surge

Using new type machine structure,there are high mechanical strength and strong sudden short-circuit bearing capability.

There is reliable shell.It can be run under harsh environment.

It is strong ability over charging,low loss,lowtemperature rise,and loe noise.

It is advanced design and reasonable structure. Also, it is small size,light weight,easy installation,and good economic performance.

The oil-immersed transformer has good insulation performance,flexible and reliable.It can be made a variety of special-type transformers.
