Oil immersed transformer
offering the choice between the Yyn0 or Dyn11 vector group configurations across a wide power range from 30 kVA to 31500 kVA. These transformers are engineered to deliver exceptional performance, efficiency, and reliability in diverse industrial and commercial settings.
The Yyn0 vector group configuration provides a specific phase shift angle, ensuring precise voltage regulation and stability in power distribution networks. On the other hand, the Dyn11 configuration offers an alternative phase shift angle, catering to varying operational requirements with flexibility and adaptability.
One of the key advantages of our transformers lies in their superior energy efficiency, reducing power losses and operational costs over the long term. With advanced design features and high-quality materials, these transformers are built to withstand demanding operating conditions and deliver consistent performance.
Oil-immersed transformers can be widely used in high-rise buildings, commercial centers, subways, airports, stations, industrial and mining enterprises, drilling platforms, and oil production platforms. They are especially suitable for use in places with high fire protection requirements and harsh environments such as flammable and explosive materials. They can also be used for power and lighting in residential areas, commercial streets, industrial and mining enterprises, and rural areas.
