Different types of insulating oils include:
Mineral oil: The most common type used in transformers, known for its good insulating properties and thermal stability.
Silicone oil: Used in high-temperature environments due to its excellent thermal stability.
Natural ester (e.g., FR3): Biodegradable and environmentally friendly, offering fire-resistant properties.
Synthetic ester: Offers similar benefits to natural ester but with enhanced performance under extreme conditions.
PCB oil: Previously used for its insulating properties but now banned due to environmental and health concerns.

Insulating oil is used in electrical equipment, such as transformers and capacitors, to insulate and cool internal components. It prevents electrical discharges, dissipates heat, and protects against moisture and oxidation. This ensures the safe, efficient, and reliable operation of the equipment, extending its overall lifespan.
