Power capacity and input/output voltage can be customized

Oil-type transformer: also known as oil-immersed transformer. It is a structural version of a transformer in which the coil of the transformer is immersed in oil. Oil-immersed transformers are generally installed in a single transformer indoor or outdoor due to the need of fire prevention. They are characterized by large volume, low cost, simple maintenance, good heat dissipation, strong overload capacity and wide adaptability to the environment.

33KV oil immersed transformer

33kV series oil immersed power transformer is advanced in design, and greatly improved in material, structure and technology. Showing strong short-circuit resistance, beautiful appearance, reliable operation, low loss and low noise, it’s performance reaches the advanced level of global similar products.

35 KV oil immersed transformer

Compared with S9 series, the no-load loss of S11 series products is reduced by 30% on average, and no-load current is 70-80% lower. The iron core is made of import high magnetic conductivity, low loss, cold-rolled high-quality silicon steel sheet, which reduces the no-load loss and saves energy significantly. It shows characteristics of high safety and reliability, advanced structure, small dimension, light weight, low noise, low temperature rise, anti-corrosion and reliable anti-leakage measures to prevent oil leakage.
