What is oil silicone used for in transformers?

Silicone oil is used in transformers as an insulating and cooling fluid, particularly in applications requiring high thermal stability. Silicone oil is known for its ability to perform under extreme temperatures and harsh environmental conditions. It provides excellent electrical insulation, prevents overheating, and has a longer lifespan compared to traditional mineral oils, making it ideal for specific high-performance or high-temperature transformer applications.
