What is the specific heat capacity of transformer oil?

The specific heat capacity of transformer oil typically ranges from 1.67 to 2.0 kJ/kg·K, depending on the specific formulation and temperature. This property is crucial for thermal management in power transformers, as it influences the oil’s ability to absorb and dissipate heat generated during operation, ensuring efficient performance and longevity of the transformer. Proper thermal management is essential to prevent overheating and maintain optimal functioning.
