High-Dielectric Transformer Oil
Transformer oil is a special oil designed for use in electrical equipment such as transformers. It is usually made from mineral or synthetic oils, and has two crucial properties. On the one hand, it has excellent insulating properties and can act as an insulating barrier in electrical equipment, ensuring safe isolation between equipment components in high-voltage environments and preventing current leakage. On the other hand, its good heat dissipation ability can take away the heat generated by the equipment operation in time to maintain the stable operation of the equipment and guarantee the reliable and efficient operation of the power system.
Product Details：High-Dielectric Transformer Oil
Employing advanced deep hydrogenation technology, this product features sulfur content below 0.001% and aromatic hydrocarbons under 5%, complying with strict EU environmental regulations. Over 95% of the product can be recycled for reuse. Specifically, in response to the space constraints of urban power grid devices, it improves flow properties to boost heat dissipation, which in turn contributes to a more than 30% increase in equipment lifespan while integrating performance, eco-consciousness, and application suitability.

1. Oil Change Inspection
Appearance check: Check the oil for visible impurities or deposits. These may be produced by aging, oxidation or contamination of the oil. If the oil becomes very dark or cloudy, it may be a sign that it needs to be replaced.
Perform an insulation resistance test: A decrease in insulation resistance may indicate the presence of moisture or other contaminants in the oil, which may affect the oil's insulating properties.
2. Applicable Industry
Wind Turbines: In the inverters and transformers found in wind turbines, transformer oil serves for insulation and cooling, maintaining equipment stability amid varying wind speeds.
Solar inverters: Transformer oil functions as a cooling agent in solar inverters, assisting in temperature regulation and improving the efficiency of energy conversion.
Reactors: Within certain chemical reactors, transformer oil is employed as a cooling and lubrication medium, helping to regulate reaction temperatures and minimize wear on equipment.
Pumps and Compressors: In chemical pumps and compressors, transformer oil acts as both a lubricant and coolant, facilitating the efficient operation of these systems.
