Fire-Resistant Natural Ester Insulating Oil
As an essential insulating medium for electrical equipment, transformer oil is mostly refined from petroleum, and its main components are alkanes and cycloalkanes. Its excellent electrical insulation can effectively separate the high-voltage components inside the transformer to prevent leakage and short circuits. Owing to its good thermal conductivity, the heat generated during the operation of the transformer can be quickly transferred, avoiding overheating and damage. Besides, it has a certain arc-extinguishing ability, able to quickly quench the arc when the switching appliance breaks the current and generates an arc.
Product Details：Fire-Resistant Natural Ester Insulating Oil
The transformer is a significant apparatus in the power grid. The safe operation of the power grid depends on the normal operation of the transformer, and the transformer oil is closely associated with the reliable operation of the transformer. Therefore, we must manage the selection, use, and administration of transformer oil properly to ensure the safe running of the transformer. As for the selection principles, first, the characteristics of the oil should be considered. Its quality must meet the needs arising from factors like the equipment's voltage level and the ambient temperature at the site. Moreover, the compatibility of the oil with other relevant insulating materials should also be factored in.

1. Applicable Industry
Industrial motors: In high-capacity motors, transformer oil functions as an insulating and cooling medium to avert overheating and guarantee efficient motor operation.
Generators: The use of transformer oils in generators is crucial for keeping operating temperatures stable and decreasing the rate of failures.
Communications Equipment: For military communications technology, transformer oil ensures insulation and cooling, which is vital for reliability in high-temperature and high-vibration scenarios.
Avionics: In aircraft electronic systems, transformer oils are essential for insulation and heat management, ensuring proper operation under high altitude and extreme weather conditions.
2. Factors Affecting Service Life
Regular quality analysis and testing are crucial for ensuring the service life of transformer oil. This testing encompasses several factors, including insulation resistance, absorption ratio, polarization index, dielectric loss, winding leakage current, and microwater content in the oil. A comprehensive review of these results allows for the detection of moisture, impurities, or signs of aging in the oil. If any issues arise, the first step may involve attempting to regenerate the oil through filtration. However, if filtration is ineffective or the oil quality is severely compromised, it will be necessary to replace the transformer oil entirely.
