Transformer Oil is highly purified non-inhibited high performance mineral oil of Class 1 category of electrical insulation oils, confirming to IS 335:1993 It is use to insulate and cool transformer coil and to quench� electric� arcs� that� form between� contacts� of� switchgears,� circuit� breakers� and� rheostats� using� mineral insulating oil. BENEFITS High insulating capacity. Effective cooling and heat dissipation due to low viscosity. Minimum risk of fire due to very high flash point. High demtilsibility to ensure good separation of water in case of accidental pollution. No impurities e.g. water, dissolved gases suspended solids, etc.. Excellent oxidation stability. Minimum consumption of product due to low volatility at operating temperatures.
