Insulating Oil For Transformers I-10
1.Excellent electrical insulation performance, with high breakdown voltage and low dielectric loss factor.
2.Good thermal stability and oxidative stability, can prevent the formation of acids and sludge during use, prolonging the service life of electrical equipment and reducing maintenance costs.
3.Does not contain corrosive sulfides such as DBDS, which can prevent the deposition of copper sulfide (CuS) on insulating paper and reduce electrical insulation performance, thereby reducing the risk of equipment failures.

Q&A
Q: What is transformer oil？
A: Transformer oil is a mineral oil or synthetic oil, typically composed of refined raw materials such as petroleum or natural gas. Through specific processing processes such as hydrogenation, desulfurization, and decolorization, impurities and harmful components can be removed, and its insulation and stability can be improved.
