Top quality, High Di-electric strength transformer oil
LUBCON Special TOII is long-life performance insulating oil and coolant with high level of dielectric strength, designed with extremely filtered thermally & chemically stable base stock to provide protection for a wide range of transformers and rheostats, circuit breakers, oil-immersed high-voltage switchgears, condensers, tap changers, electrical reclosures, fuses and other electrical equipments, operating under critical conditions, subject to great thermal stresses.
Specifications: Transformer Oil Inhibited: ASTM D3487 Type IIA (inhibited), Transformer Oil: ASTM D3487 Type II
Benefits:
- Excellent fluidity provides efficient functioning at extremely low temperature and ensures superior convective and conductive heat transfer to improve cooling of transformer components.
- High dielectric strength and low dissipation factor provide superior insulating performance.
- Improved resistance to acid and sludge formation due to absence of asphaltic and resinous materials.
- Effective anti-oxidation inhibitor controls the formation of sludges, deposits and soluble compounds which break down the electrical properties of the oil.
