What characteristics define high-performance silicone oil for transformer applications?

High-performance silicone oil for transformers is characterized by its exceptional dielectric strength, thermal stability, and chemical inertness. It should maintain consistent insulating and cooling properties over a wide temperature range and under various electrical stresses. Low flammability and a high flash point enhance safety, while resistance to oxidation and moisture absorption extends the oil’s service life. Additionally, compatibility with transformer materials and environmental friendliness are important attributes that define high-quality silicone transformer oil.
