What is the thermal conductivity of transformer oil?

The thermal conductivity of transformer oil typically ranges from 0.1 to 0.2 W/m·K. This property is crucial for the effective cooling of transformers, as it allows for efficient heat dissipation. High thermal conductivity in transformer oil facilitates the transfer of heat generated by electrical equipment to the surrounding structure, helping to maintain optimal operating temperatures. Regular monitoring and maintenance of transformer oil’s thermal properties are essential to ensure reliable performance and longevity of the transformer.
