EQUINAS NBO 60u is a high-quality Naphthenic Base Oil with very good dielectric properties and oxidation stability intended for transformers, switchgears, and other electrical equipment. Naphthenic base oil is a type of mineral oil that is produced through the refining of crude oil. It characterized by its composition of saturated cyclic hydrocarbons called naphthene. Naphthenic base oils are used in a wide range of applications, including automotive lubricants, transformer oils, metalworking fluids, rubber and tire manufacturing, and more. They are particularly well-suited for use in applications where low-temperature performance is critical, such as in hydraulic fluids, refrigeration oils, and compressor lubricants
