What is high voltage transformer oil used for?

High voltage transformer oil is primarily used as an insulating and cooling medium in electrical transformers, ensuring efficient operation by preventing overheating and maintaining electrical insulation between conductive parts. Its excellent dielectric properties help to prevent electrical breakdown, while its thermal conductivity aids in effectively dissipating heat generated during the transformation of high voltage electricity. Additionally, high voltage transformer oil protects internal components from moisture and contaminants, which can lead to degradation and reduced transformer lifespan. Therefore, its role is critical in the reliability and performance of electrical power systems.
