Antioxidant Enhanced Insulation Liquid
As a critical insulating medium for electrical equipment, transformer oil is mostly refined and extracted from petroleum, with alkanes and cycloalkanes as its main constituents. Its excellent electrical insulation can effectively separate the high-voltage components within the transformer to prevent leakage and short circuits. Thanks to its good thermal conductivity, the heat generated during the transformer's operation is quickly dissipated, avoiding overheating and damage. Additionally, it has a certain arc-extinguishing capacity, which can quickly quench the arc when the switching appliance cuts off the current and generates an arc.
Product Details：Antioxidant Enhanced Insulation Liquid
Transformer is an important piece of equipment in the power grid, transformer can operate normally in relation to the safety of the power grid, and the transformer oil is directly related to the reliability of transformer operation. Therefore, we must do a good job of transformer oil selection, use and management work to ensure that the transformer operation safety. Selection of the principle, first of all, is to consider the performance of oil, quality to meet the equipment voltage level, the location of the ambient temperature and other factors on the oil requirements, in addition, should also consider the compatibility of oil and other relevant insulating materials.

1. Applicable Industry
Industrial motors: In high power motors, transformer oil is used for insulation and cooling to prevent overheating and to ensure efficient operation of the motor.
Generators: In generators, transformer oils help maintain stable operating temperatures and reduce failure rates.
Communications Equipment: In military communications equipment, transformer oil provides insulation and cooling to ensure reliability in high temperature and vibration environments.
Avionics: In aircraft electronics, transformer oils are used to insulate and dissipate heat, ensuring proper operation at high altitudes and in extreme weather conditions.
2. Factors Affecting Service Life
The design life of a transformer is an important determinant of the transformer oil's lifespan. Generally, this design life is calculated based on the expected longevity of the oil. Thus, during its design life, the transformer oil should be able to meet the operational needs of the transformer. Environmental conditions such as high temperatures, humidity, and pollution also play a role in the service life of transformer oil. In adverse environments, the oil may age more quickly, thereby shortening its lifespan.
