How does the chemical stability of silicone oil affect transformer longevity and safety?

The chemical stability of silicone oil significantly impacts both the longevity and safety of transformers. Chemically stable silicone oil resists oxidation and degradation even under high thermal and electrical stresses, which prevents the formation of acidic byproducts and sludge that can corrode transformer components. This resistance ensures that the oil maintains its high dielectric strength and thermal conductivity over extended periods, reducing the need for frequent oil replacements and maintenance interventions. Additionally, chemical stability minimizes the risk of insulation failure and electrical discharges, enhancing transformer safety by preventing potential fire hazards and operational failures. Consequently, the robust chemical stability of silicone oil contributes to the prolonged service life of transformers and ensures their reliable and safe operation.
