Environmentally Friendly Ester-Based Fluid
Transformer oil is generally classified based on its derivation from paraffinbased or naphthenic crude oil. However, due to developments in hydrogenation and reforming processes, paraffinbased crude oil can also produce transformer oil with properties akin to those derived from naphthenic crude oil. In evaluating transformer oil base oils, it is essential to consider not only the conventional physical and chemical properties but also the carbon structure, often referred to as family composition. This concept of carbon structure treats the complex base oil as a singular molecule composed of three structural elements: aromatic rings, naphthenic rings, and alkyl side chains. The Cp value denotes the percentage of carbon atoms present in the alkyl side chain relative to the total carbon atoms in the molecule.
Product Details：Environmentally Friendly Ester-Based Fluid
In the context of transformers, capacitors, and cables, mineral insulating oils derived from naphthenic crude oils should be prioritized. These oils need to demonstrate stability in their physical and chemical properties when exposed to electromagnetic fields and various environmental conditions, which is essential for the safety and reliability of electrical equipment. The refining of insulating oils for electrical equipment should focus on naphthenic hydrocarbons as the foundational components, ensuring the inclusion of a sufficient amount of stable aromatic hydrocarbons while minimizing the removal of paraffinic hydrocarbons, which are susceptible to cleavage due to their long straightchain configuration.

1. Environmental Friendliness of Transformer Oil
Recycling and reuse: Transformer oils can undergo reprocessing using both physical and chemical techniques to eliminate impurities and contaminants, effectively restoring their functionality.
Reclaimed Oil: Oils that have been reprocessed can possess properties comparable to those of new oils, minimizing resource waste and decreasing the demand for new raw materials. Utilizing recycled oil is not only cost-effective but also alleviates environmental pressure.
2. Factors Affecting Service Life
The design life of the transformer is a key factor that influences the lifespan of the transformer oil. Generally, this design life is aligned with the expected service life of the oil. Consequently, within the design life, the transformer oil should adequately meet the operational demands. Environmental factors such as high temperatures, humidity, and pollution can also impact the service life of transformer oil. In unfavorable conditions, the oil's aging process accelerates, resulting in a reduced lifespan.
