A type of lubricating oil. Usually formulated by adding antioxidants to deeply refined lubricating oil base oil. Mainly used as a dielectric for electrical equipment. The main properties of insulating oil are low-temperature performance, oxidation stability, and dielectric loss. Low temperature performance refers to the necessary fluidity for oil to automatically convection, export heat, and instantly cut off arc current in electrical equipment under low temperature conditions. Generally, it is required that the insulation oil has a low pour point and a low viscosity at low temperatures. In electrical equipment, oil is oxidized by the action of heat and oxygen under the action of an electric field for a long time. Oil products added with antioxidants and metal passivators have better oxidation stability. Dielectric loss refers to the degree of dielectric loss of an oil product under an AC electric field, usually measured by the dielectric loss angle（ δ) Tangent value of (tan δ) Represent
