What are the technical aspects of transformer oil 25?

Transformer oil 25, often referred to as mineral oil, is a key insulating and cooling medium in power transformers. Its technical aspects include a high dielectric strength, low viscosity for effective heat transfer, and excellent thermal stability. Additionally, it has a high flash point, reducing fire risk, and contains additives to inhibit oxidation and improve performance. Regular testing for moisture content, acidity, and dielectric strength is essential to ensure optimal transformer operation and longevity.
