What is naphthenic based transformer oil and how is it used in power transformers?

Naphthenic based transformer oil is a type of insulating oil derived from naphthenic crude oil, characterized by its high dielectric strength and thermal stability. In power transformers, naphthenic based transformer oil is used for insulation and cooling, effectively dissipating heat generated during operation. Its chemical properties enhance the performance and longevity of transformers, making it suitable for high-performance applications in electrical systems.
