What are the technical aspects of high voltage transformer oil?

High voltage transformer oil serves as an insulating and cooling medium in power transformers. Key technical aspects include its dielectric strength, which must exceed 30 kV for effective insulation, and its thermal conductivity, which facilitates heat dissipation. The oil’s viscosity is crucial for maintaining flow at varying temperatures, while its chemical stability prevents degradation. Additionally, the presence of additives enhances oxidation resistance and minimizes moisture absorption, ensuring reliable transformer operation and longevity.
