Low-Temp Startup Transformer Oil
Transformer oil, a specialized oil for electrical equipment like transformers, is usually composed of mineral or synthetic oils and has two vital properties. On one side, it has excellent insulation performance, acting as an insulating barrier in electrical equipment to ensure safe isolation of components in high-voltage environments and prevent current from leaking. On the other side, its good heat dissipation capacity can timely remove the heat generated by equipment operation, maintaining stable equipment operation and ensuring the reliable and efficient operation of the power system.
Product Details：Low-Temp Startup Transformer Oil
With a specialized deep hydrogenation technique, this product achieves a sulfur content of less than 0.001% and aromatic hydrocarbon content of less than 5%, adhering to EU environmental criteria. Its recycling rate exceeds 95%. In addition, optimized for the compact structure of urban power grid equipment, the product refines its fluidity to upgrade heat dissipation capabilities. This not only supports extending equipment service life by over 30% but also ensures comprehensive compatibility across performance, environmental protection, and real-world usage scenarios.

1. Oil Change Inspection
Oil Appearance Check: Look for visible impurities or deposits in the oil, which could be caused by aging, oxidation, or contamination. If the oil appears excessively dark or cloudy, it may be a sign that it requires replacement.
Testing Insulation Resistance: It is important to carry out an insulation resistance test. A decrease in resistance may reveal the presence of moisture or contaminants in the oil, adversely affecting its insulating properties.
2. Factors Affecting Service Life
Regular quality analysis and testing are important for maintaining the service life of transformer oil. This involves checking insulation resistance, absorption ratio, polarization index, dielectric loss, winding leakage current, and the oil's microwater content. A detailed analysis of these results can help determine if the oil is damp, contains impurities, or is aging. If issues are identified, the first step might be to regenerate the oil through filtration. However, if this method is ineffective or the oil quality is severely compromised, replacing it with new transformer oil is necessary.
