Overview of ONAN Transformers
The ONAN transformer, which stands for Oil Natural Air Natural, is a type of transformer that utilizes oil for cooling and relies on natural air circulation for heat dissipation. This design is particularly effective in ensuring that the transformer operates efficiently under various load conditions. ONAN transformers are widely used in industrial applications due to their reliability and cost-effectiveness.
