What is Nynas oil used for in transformers?

Nynas oil is used for transformers primarily as an insulating and cooling medium. Its specific formulation provides excellent electrical insulation properties, thermal stability, and low viscosity, which are crucial for efficient heat dissipation in power transformers. Additionally, Nynas oil has good oxidation stability, which helps prolong the life of the transformer by minimizing the formation of harmful byproducts during operation.
