Transformer Oil
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.
The products fully meet the international and national specifications such as IS-335 2018, IEC 60296:2020, ASTM D 3487, BS 148, JIS, AS, ASTM. The inhibited grades have DBPC as additive, which is part of the approved list of inhibitors as per IEC 60296.
The products are strictly free from PCB, DBDS or any passivator or metal de-activator. They offer excellent oxidation stability with very low acid and sludge formation when tested according to IEC 61125 and ASTM D2440 besides having excellent dielectric strength, resistivity & dissipation factor. The low pour point and low viscosity characteristics of the product enable excellent cooling properties.
Applications
-
Transformer oil acts as a coolant, dissipating the heat generated during the operation of transformers. It helps maintain an optimal temperature, preventing overheating and extending the lifespan of the transformer.
-
Transformer oil provides electrical insulation between the internal components of transformers, such as coils and windings, preventing short circuits and ensuring safe and reliable operation.
-
In certain types of transformers and switchgear, transformer oil is used to quench electric arcs that occur during switching operations, protecting the equipment from damage and ensuring operational safety.
-
Transformer oil enhances the dielectric strength of transformers, enabling them to withstand high voltages and electrical stresses without breaking down. This is critical for maintaining the integrity and performance of electrical systems.
