What is the role of 110 kV power transformer oil in power transformers?

The role of 110 kV power transformer oil in power transformers is crucial for both insulation and cooling. This oil acts as an insulating medium, preventing electrical discharges between conductive components, while also dissipating heat generated during operation. Additionally, the 110 kV power transformer oil helps to protect the internal components from moisture and contaminants, thereby enhancing the overall reliability and longevity of the transformer.
