Oil Immersed Distribution Transformers

HV:11KV/22KV/35KV


Energy-saving oil immersed transformer is our company through the research and application of new materials and new processes, and the combination of independent innovation and technology introduction. Through the optimization and innovative design of the core and coil structure, it can reduce the no-load loss and noise. Purpose, self-developed product.


Application:

Residential districts, high-tech centers, factories and mining enterprises, airports, stations, schools and other places


Advantages of power transformer structure

We use spiral coils with longitudinal oil circuits to achieve better internal cooling effect;

We have improved the effective support of the coil terminal surface to enhance the ability to withstand short-circuit current.

We adopt new lifting structure and body positioning frame to ensure long-distance transportation and movement will be more reliable;

The fuel tank is eliminated, and the corrugated wing of the fuel tank replaces the fuel pipe as a cooling device. The corrugated box is made of high-quality cold-pressed plates on a special machine, which improves the reliability of operation.
