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

Electrol transformer oil is a specialized insulating oil used in power transformers to provide electrical insulation and cooling. It is formulated to have high dielectric strength, thermal stability, and low viscosity, which enhances its performance in high-voltage applications. In power transformers, electrol transformer oil helps dissipate heat generated during operation and protects internal components from electrical arcing and moisture, ensuring reliable and efficient transformer performance.
