What are the technical aspects of transformer oil formula?

The technical aspects of transformer oil formula primarily involve its chemical composition, which typically includes mineral oil, additives, and sometimes synthetic compounds. Key properties include high dielectric strength, low viscosity, and excellent thermal conductivity. Additives are used to enhance oxidation stability, prevent foaming, and improve fire resistance. The oil must also have a low pour point to ensure effective operation in varying temperatures, ensuring optimal performance and longevity of the transformer.
