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

The role of transformer 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 transferring it to the radiator or cooling system. Additionally, transformer cooling oil provides electrical insulation, protecting components from electrical breakdown and enhancing the overall reliability and longevity of the power transformer.
