What is distribution transformer oil used for?

Distribution transformer oil is primarily used as an insulating and cooling medium in distribution transformers, which are crucial for stepping down high voltage electricity for residential and commercial use. It helps to dissipate heat generated during operation, ensuring optimal temperature regulation and improving transformer efficiency. Additionally, distribution transformer oil provides electrical insulation, preventing arcing and short-circuiting within the transformer. Its properties also protect against moisture and corrosion, extending the lifespan of the transformer and enhancing its reliability. Overall, distribution transformer oil plays an essential role in maintaining the performance and durability of electrical distribution systems.
