ELECTROL® today synonymous with the most trusted name in transformer oils. Widely used in transformers, oil immersed circuit breakers and switchgears. Transformer oils are mineral electrical insulating oils processed from super refined, carefully selected premium basestocks. Some of the outstanding attributes of ELECTROL® are
In the conventional sense, transformer oils provide cooling, electrical insulation, indicative information on health of transformer, have system compatibility and are expected to give long life performance.
However, ELECTROL® Transformer Oils, designed for use in the new millennium, go beyond the above conventional expectations and provide:

In recent years, presence of corrosive sulphur in transformer oil, originating from the base fluid used in the oil has been a matter of serious concern. There have been numerous documented cases of failure traced to presence of corrosive sulphur, leading to elaborate investigations all over the industry. Naphthenic base oils, traditionally regarded as the best base fluids for transformer oils cannot be made totally devoid of sulphur, even by the best available techniques. Some manufacturers use passivators as additives in transformer oils to reduce the effect of corrosive sulphur. This approach only marginally reduces the risk of corrosive sulphur effect. The key to transformer oil performance therefore is directly linked to use of better base oil with zero sulphur made from advanced refining technology.
Modern techniques for production of high quality iso-paraffin base oils involves severe hydrocracking, followed by hydroisomerization to produce outstanding iso-paraffin base oils with zero corrosive sulphur. Any residual wax in the oil is converted to base oil. The refining technique totally removes sulphur, as well as other undesirable constituents like oxygen, nitrogen, metallic compounds, aromatics and inorganic salts. The result is a highly stable water-white iso-paraffin base oil ideally suited for manufacture of premium quality transformer oils.
All paraffinic based ELECTROL® Transformer Oils are formulated from highly stable iso paraffinic base oils of the purest Group 2 and Group 3 Specifications. As a result, these products offer highest security against corrosion in usage
