What are the technical aspects of types of transformer oil?

The technical aspects of types of transformer oil include their chemical composition, dielectric strength, thermal conductivity, and viscosity. Mineral oils, commonly used, provide good insulation and cooling properties but may have lower fire resistance. Synthetic oils, such as esters, offer higher fire safety and biodegradability. Additionally, natural ester oils have excellent thermal properties and are environmentally friendly. Each type’s performance is influenced by factors like temperature range and electrical stress, impacting transformer efficiency and longevity.
