What is power oil transformer oil?

Power oil transformer oil is a specialized insulating oil used in electrical transformers to provide electrical insulation, heat dissipation, and protection against moisture and oxidative degradation. This type of oil is crucial for maintaining the efficiency and longevity of transformers, as it helps to cool the internal components and prevent short circuits due to its excellent dielectric properties. Additionally, power oil transformer oil undergoes rigorous testing and purification processes to remove impurities and enhance its performance in high-voltage applications, ensuring reliability and safety in power systems.
