What is the role of transformers cooling oil in power transformers?

The role of transformers cooling oil in power transformers is to dissipate heat generated during operation, ensuring optimal performance and preventing overheating. This cooling oil circulates within the transformer, absorbing heat from the core and windings, and then transfers it to the radiator or cooling system. Additionally, transformers cooling oil provides electrical insulation, protecting the internal components from electrical breakdown and enhancing the overall reliability and lifespan of the transformer.
