What are the properties of synthetic transformer oil?

Synthetic transformer oil possesses several key properties that enhance its performance in power transformers. These include high thermal stability, which allows for efficient heat dissipation, and excellent dielectric strength, ensuring electrical insulation. Additionally, synthetic transformer oil has low viscosity, improving flow characteristics at low temperatures, and a high flash point, which enhances safety. Its chemical stability also reduces the risk of oxidation, prolonging the lifespan of the transformer.
