Used Transformer Oil Dealers in Mumbai

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.

Transformer Oils are electrical insulating oils produced by distillation of virgin paraffinic and naphthenic crude oils followed by modern technologies involving high pressure hydrogenation and hydro-treatment. All the processes are monitored closely and appropriate Base Oil fractions are selected for further processing. Further processing involves removal of moisture and polar impurities to obtain good electrical properties. The technologies result in products with very low pour point, excellent oxidation stability, cooling characteristics and electrical properties. These properties make them suitable for the most demanding transformer applications.

Transformer Oil or Dielectric Insulation Oil and other oils required for electrical machinery and installations can be manufactured using hydro finished base oils of group II +. The base stocks are selected based on viscosity requirements of the user. In colder countries pour point is also a critical property for base oil selection. Transformer Oil (TO) be used for filling the transformer with a primary objective of providing electrical insulation between the primary and secondary coils. Dissipation of heat generated during the process is also an important function. Electrical insulation is favored by high viscosity and heat dissipation is favored by low viscosity and circulation of fluid. Base oil viscosity at a compromise level is selected. Viscosity ranges for base oil slightly defer country to country, generally in the range of 10 to 40 cst. at 400 Degree C. During the service temperature of oil rises to about 60-800 Degree C. Viscosity of oil decreases due to temperature rise. Transformer has large extended surfaces exposed to atmosphere. The oil circulates through these tubes and dissipates heat into the atmosphere.
