what is the viscosity of transformer oil?

The viscosity of transformer oil typically ranges from 10 to 20 centistokes (cSt) at 40�C. This property is crucial as it affects the oil’s ability to cool and insulate electrical components within the transformer. Lower viscosity allows for better flow and heat transfer, while higher viscosity can impede circulation. It’s essential to select transformer oil with appropriate viscosity to ensure optimal performance and longevity of the transformer.
