Hydroprocessed Naphthenic Transformer Fluid
Transformer oil, a necessary insulating medium for electrical equipment, is largely extracted and refined from petroleum, with alkanes and cycloalkanes being its primary components. With excellent electrical insulation properties, it can efficiently isolate the high-voltage parts within the transformer, thus stopping leakage and short circuits. Due to its good thermal conductivity, it can rapidly carry away the heat produced during the transformer's operation, preventing overheating and damage. It also has some arc-extinguishing capability, quickly extinguishing the arc when the switching device interrupts the current and forms an arc.
Product Details：Hydroprocessed Naphthenic Transformer Fluid
In the power grid, the transformer is an essential piece of equipment. The normal operation of the transformer is key to the safety of the entire power grid system, and the performance of the transformer oil directly impacts the reliability of the transformer's operation. Consequently, we have to perform well in the selection, application, and management of transformer oil to ensure the secure operation of the transformer. When it comes to the selection criteria, first and foremost, the performance of the oil needs to be considered. Its quality must meet the requirements determined by factors including the voltage level of the equipment and the ambient temperature of the location. Besides, the compatibility between the oil and other related insulating materials must also be taken into account.

1. Applicable Industry
Industrial motors: Transformer oil is utilized in high-power motors for insulation and cooling, helping to prevent overheating and ensuring that the motor operates efficiently.
Generators: In the context of generators, transformer oils assist in maintaining consistent operating temperatures and reducing the chances of equipment failure.
Communications Equipment: In military-grade communications devices, transformer oil provides both insulation and cooling, ensuring reliability in environments characterized by high temperatures and vibrations.
Avionics: Within avionics systems, transformer oils are employed to provide insulation and dissipate heat, ensuring that equipment functions correctly at high altitudes and in severe weather conditions.
2. Factors Affecting Service Life
To maintain the longevity of transformer oil, it is essential to conduct regular quality analysis and testing. The testing process includes evaluating insulation resistance, absorption ratio, polarization index, dielectric loss, winding leakage current, and the presence of microwater in the oil. By thoroughly analyzing these results, one can identify issues such as moisture content, impurities, or aging. If problems are detected, an initial step can be to attempt oil regeneration through filtration for continued use. However, if filtration does not resolve the issue or if the oil quality has significantly declined, replacing the transformer oil with a new supply becomes necessary.
