What is transformer inhibited mineral oil used for in power transformers?

Transformer inhibited mineral oil is used for insulation and cooling in power transformers. It provides excellent dielectric properties, ensuring electrical insulation between live parts and the transformer structure. Additionally, the inhibited formulation contains additives that enhance oxidation stability, preventing degradation over time. This helps maintain the oil’s performance, prolonging the lifespan of the transformer and ensuring reliable operation under varying thermal and electrical conditions.
