What is SF6 transformer oil used for?

SF6 transformer oil is primarily used as an insulating and cooling medium in electrical transformers and switchgear. Its unique properties, including high dielectric strength and excellent thermal conductivity, make it ideal for protecting electrical components from overheating and short-circuiting. Additionally, SF6, or sulfur hexafluoride, has excellent arc-extinguishing characteristics and is often used in gas-insulated switchgear (GIS) systems, enhancing safety and efficiency in high-voltage applications. The combination of SF6 with transformer oil helps to ensure reliable operation and longevity of electrical equipment in various industrial applications.
