APAR pioneered the manufacture of internationally benchmarked grades of high performance Transformer Oils in India that were more environment friendly and of high performance with higher oxidation stability, lower gassing tendency and non corrosive with ultra low levels of sulphur.
Apar produces a comprehensive range of high quality Transformer oils from selected severely hydro treated Naphthenic and Isodewaxed / hydrocracked Isoparaffinic 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. These 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.
