The name of the transformer oil used in power transformers is mineral oil, specifically classified under ASTM D3487 as Type I or Type II. These oils are refined to have high dielectric strength and thermal stability, ensuring efficient insulation and cooling in power transformers. Additionally, some power transformers may use synthetic ester oils, which offer enhanced fire safety and environmental benefits.
