What are the technical aspects of paraffin based transformer oil?

Paraffin-based transformer oil is characterized by its high dielectric strength, excellent thermal stability, and low viscosity, which enhance heat dissipation. Its chemical stability minimizes oxidation and sludge formation, prolonging transformer life. Additionally, paraffin oils have a high flash point, improving safety. They also exhibit good insulation properties, making them suitable for high-voltage applications. However, their environmental impact and lower biodegradability compared to ester-based oils are important considerations in modern transformer design.
