What are the technical aspects of naphtha based transformer oil?

Naphtha-based transformer oil is derived from petroleum and is characterized by its low viscosity and high dielectric strength. Its technical aspects include excellent thermal conductivity, which enhances heat dissipation, and a high flash point, ensuring safety during operation. Additionally, naphtha-based oils exhibit good oxidation stability, reducing the risk of sludge formation. However, they may have lower biodegradability compared to ester-based oils, which is a consideration for environmental impact.
