How is silicone oil utilized in high-voltage transformers?

In high-voltage transformers, silicone oil provides superior insulation and cooling under extreme electrical stresses. Its high dielectric strength prevents electrical breakdowns between components operating at elevated voltages. The oil’s thermal stability manages the significant heat generated in high-voltage applications, preventing overheating and thermal degradation of insulation materials. Additionally, silicone oil’s fire-resistant properties enhance safety in high-voltage environments.
