Produces comprehensive range of high quality Transformer oils from selected severely hydrotreated Naphthenic and Isodewaxed / hydrocracked Paraffinic Oils free from polar compounds and have very high oxidation stability and ageing properties guaranteeing long service life. The low sulphur wax free naphthenic oils with low Viscosity Index ensure excellent cooling characteristics, high solvency and low corrosivity and the highly refined ultra low sulphur paraffinic oils ensure excellent non corrosive properties. This optimum refined Transformer Oils also possess very good electrical and insulating properties, oxidation stability and controlled low or negative gassing tendency. Extensive efforts are taken to up grade our oils to meet the latest more severe and stringent control requirements of non   corrosive oils.

APAR pioneered internationally benchmarked grades of high performance Transformer Oils in India that were more environment friendly with higher oxidation stability, lower gassing tendency and ultra low levels of corrosive sulphur.
