Thermally Upgraded Naphthenic Insulation Oil
From the general concept, transformer oil is divided into from paraffinbased crude oil and naphthenic crude oil production, but with the development of hydrogenation and reforming process, paraffinbased crude oil can also produce pour point and naphthenic crude oil with Wanmei transformer oil. Evaluation of transformer oil base oil, in addition to the conventional physical and chemical properties, the most common method of carbon structure (also known as the structure of the family composition). The socalled carbonbased structure, that is, the composition of the complex base oil is viewed as a single molecule by the aromatic ring, naphthenic ring and alkyl side chain of the three structural components, Cp value refers to the carbon atoms on the alkyl side chain of the entire molecule as a percentage of the total carbon.
Product Details：Thermally Upgraded Naphthenic Insulation Oil
When insulating oils are utilized in transformers, capacitors, and cables, it is advisable to prioritize mineral insulating oils derived from naphthenic crude oils. These oils must remain stable in both physical and chemical properties when subjected to electromagnetic fields and other environmental conditions to ensure the safety and reliability of electrical equipment. The refining process for these insulating oils should be based on naphthenic hydrocarbons as the primary components, including a sufficient amount of stable aromatic hydrocarbons, while aiming to remove paraffinic hydrocarbons that are prone to cleavage due to their long straightchain structure.

1. Environmental Friendliness of Transformer Oil
Recycling and reuse: Transformer oils can be reprocessed through physical and chemical methods to remove impurities and contaminants, thereby restoring their performance.
Reclaimed Oil: Transformer oils that have been reprocessed can achieve similar properties to new oil, reducing the waste of resources and lowering the need for new raw materials. The use of recycled oil is not only economical, but also reduces the burden on the environment.
2. Factors Affecting Service Life
The lifespan of transformer oil is significantly affected by the design life of the transformer. Typically, the design life is defined based on the expected service life of the oil. Therefore, throughout this design life, the transformer oil should fulfill the operational requirements of the transformer. Additionally, environmental factors like high temperatures, humidity, and pollution can influence the oil's service life. In poor environmental conditions, the aging of the oil accelerates, leading to a shorter lifespan.
