What is the oil used in transformers for?

The oil used in transformers serves multiple critical functions. Primarily, transformer oil acts as an insulating medium, preventing electrical discharges between conductive components. Additionally, it facilitates heat dissipation, absorbing and transferring heat generated during operation to maintain optimal temperature levels. The oil also provides protection against moisture and contaminants, ensuring the longevity and reliability of the transformer. Overall, the oil used in transformers is essential for safe and efficient operation.
