Transformer Oil is the basic material of power substation system, according to the pour point and dotted coagulation 25 #, 45 # two brands, mainly composed of naphthenic base crude oil production. With insulation and cooling.Provide electrical insulating properties, low conductivity and high voltage resistance ability, and reduces the power loss of the equipment. Good capability of heat transfer, suitable viscosity, low pour point. By convection, hot and cold circulating reflux way, will transmit heat in time, avoid the transformer over temperature.

Because the transformer is mainly composed of copper wire, iron core insulation and cellulose, such as transformer oil has good oxidation resistance ability, can keep synchronization with transformer life.

Excellent electrical insulation: Breakdown voltage of the transformer oil measured at least once a year. Main function is to provide electric insulation performance , has very low electrical conductivity and high voltage resistance ability. Reduce the power loss of the equipment. Effectively prevent the high voltage field discharge phenomenon. Control the specific gravity of transformer oil, 20 °C density is not more than 895 kg/m³.

Transformer-Oil-3High Cooling Effect: what is the oil used in transformer ? viscosity is appropriate, the cooling effect. By means of cold and heat convection, circulating reflux can transmit timely heat, avoid the transformer overtemperature. Provide effective cooling heat conduction speed, and transitivity. Pour point can be lower than to -40 °C, low temperature performance is good, without any admixture.

Strong Antioxidant: high dielectric strength, low dielectric loss factor, good thermal stability and oxidation stability, can prevent the production of acid and oxides. The corrosive sulfur in the transformer oil tends to zero. Because the power transformers is mainly composed of copper wire, iron core insulation and cellulose, etc. The determination of interfacial recogniton transformer oil, the trend of make reliable judgment. Has good oxidation corrosion resistance, and greatly prolong the service life of electrical equipment.
