what type of oil is used in transformers？The answer from a China transformer manufacturer

As is known, oil in transformers is used for insulation and heat dissipation. Then, do you know what are the types of the transformer oil？ Here is the answer from a professional transformer manufacturer in China.

Transformer oil is a fractionation product of petroleum, its main components are alkane, naphthenic saturated hydrocarbons, aromatic unsaturated hydrocarbons and other compounds. It is commonly known as square shed oil, light yellow transparent liquid, relative density of 0.895, Freezing point <-45 ℃.

Transformer oil is a kind of mineral oil obtained by distillation and refining in natural petroleum. It is a mixture of liquid natural hydrocarbons with pure stability, low viscosity, good insulation and good cooling ability after refining of lubricating oil fractions in oil by acid and alkali. Commonly known as square shed oil, light yellow transparent liquid.
