What is the purpose of oil in electrical transformers?

The purpose of oil in electrical transformers, specifically regarding «oil immersed transformer specification,» is to serve multiple critical functions including insulation, cooling, and arc suppression. The oil provides electrical insulation between live components, ensuring safe operation under high voltage conditions. Additionally, it absorbs and dissipates heat generated during the transformer’s operation, preventing overheating and thus maintaining optimal efficiency. The dielectric properties of the oil also contribute to the suppression of electrical arcs, enhancing the overall reliability and lifespan of the transformer. In summary, oil is essential for the safe, efficient, and reliable functioning of oil immersed transformers.
