What is 10c transformer oil used for in power transformers?

10c transformer oil is used for insulation and cooling in power transformers. This type of transformer oil has specific properties that enhance its dielectric strength and thermal conductivity, making it effective in preventing electrical discharges and dissipating heat generated during transformer operation. Additionally, 10c transformer oil helps to protect the internal components of power transformers from oxidation and degradation, ensuring reliable performance and longevity.
