TRANSFORMER OIL
VELVEX Transformer oils are manufactured from a selection of hydro treated virgin base oils, adopting latest state of the art technology to produce a finished product that plays a vital role in protecting and insulating the key components of the transformer.
-
Liquid insulation in Power transformers
-
Dissipates heat of the transformer i.e acts as a coolant
-
Preserve Core & winding
-
Prevents direct contact of atmospheric oxygen with cellulose made paper insulation of windings, which is susceptible to oxidation
-
Optimum Insulation: High BDV, high interfacial surface tension and the absence of polar impurities ensure optimum insulation and protection of the transformers
-
Higher flash point, resulting on low evaporation losses and better safety
-
Low Viscosity ensures good fluidity and heat transfer capabilities to maintain appropriate temperatures
-
Higher Resistivity : High Insulation resistance between transformer windings prevent damage & reduce downtime
-
Highly Refined Oil with advanced base oil technology, Ensures Oxidation stability & Longer life of oil
-
Non Corrosive: Highly refined with low sulfur content, hence non corrosive in service, free from DBDS and PCB
Based upon the present international standards and specific requirements, we offer transformer oils on following major categories
-
Uninhibited Transformer oil – Recommended for standard equipment, operates at normal conditions
-
Inhibited Transformer oils – Recommended for operations at higher temperature & where higher oxidation resistance is required
-
Trace inhibited transformer oils
-
Specialty High Grade Transformer oils
