How does silicone oil compare to mineral oil in transformers?

Silicone oil vs mineral oil transformer applications reveal significant differences in properties and performance. Silicone oil generally offers better thermal stability, wider operating temperature range, and superior electrical insulation properties compared to mineral oil. This makes silicone oil less likely to break down under high temperatures, leading to longer equipment life in transformer applications. Additionally, silicone oil is less flammable, providing enhanced safety for transformers in critical environments. However, mineral oil is often preferred due to its lower cost and adequate performance in many scenarios. Choosing between the two depends on specific transformer requirements and operational conditions.
