Superior High - Performance Transformer Oil
For electrical equipment, transformer oil serves as a crucial insulating medium, mostly extracted and refined from petroleum, with alkanes and cycloalkanes as its main components. Its excellent electrical insulation can effectively insulate the high-voltage components within the transformer, thus avoiding leakage and short circuits. Due to its good thermal conductivity, it can rapidly transmit the heat generated during the transformer's operation, preventing overheating and damage. Furthermore, it has a certain ability to extinguish arcs, quickly putting out the arc when the switching appliance interrupts the current to produce an arc.
Product Details：Superior High - Performance Transformer Oil
In the context of the power grid, the transformer is an indispensable device. The normal operation of the transformer is crucial for the safety of the power grid, and the transformer oil is directly relevant to the reliability of the transformer's operation. So, we must execute the tasks of choosing, using, and overseeing transformer oil effectively to ensure the secure operation of the transformer. Regarding the principles of selection, first, the performance of the oil should be examined. Its quality must comply with the demands brought about by factors like the voltage level of the equipment and the ambient temperature of the area. Furthermore, the compatibility of the oil with other related insulating materials should be considered.

1. Environmental Friendliness of Transformer Oil
Environmental monitoring: Consistent monitoring of the environment and regular maintenance of transformers and other electrical equipment can significantly lower the chances of leaks.
Utilizing an oil spill monitoring system enables quick identification of issues, allowing for prompt corrective actions.
Spill contingency measures: It is crucial to create and implement a robust spill contingency plan to facilitate a swift response in case of a spill, minimizing environmental impact. Additionally, training employees in emergency response procedures ensures they can react effectively during emergencies.
2. Factors Affecting Service Life
Ensuring the service life of transformer oil requires regular quality analysis and testing. The detection process involves checking insulation resistance, absorption ratio, polarization index, dielectric loss, winding leakage current, and microwater levels in the oil. By analyzing these factors, one can ascertain whether the oil has absorbed moisture, contains impurities, or shows signs of aging. If problems are identified, an initial approach may be to regenerate the oil through filtration. However, if this method is impractical or the oil quality is severely degraded, a replacement with new transformer oil should be considered.
