What are the technical aspects of electrol transformer oil?

Electrolytic transformer oil is a highly refined mineral oil used in power transformers for insulation and cooling. Key technical aspects include its dielectric strength, which must exceed 30 kV for effective insulation, and its low viscosity to ensure efficient heat transfer. Additionally, it has a high flash point (typically above 140°C) for safety, and it contains additives to inhibit oxidation and improve thermal stability, ensuring long-term performance and reliability in electrical applications.
