• Very low sulphur and no DBDS. • Low Pour point. • High dielectric strength. • Non corrosive as tested by all present methods, DIN & ASTM tests & New IEC 62535 method. • Low viscosity oils offering excellent and fast heat transfer. • Higher Flash point, resulting on Low evaporation losses and better safety • Remarkably low sludge and acidity formation, in both ageing and oxidation tests, results in longer life of oil and equipment • Compatible with transformer construction material
Eiffel Elect Oil IH Inhibited Transformer oils are highly suitable for all grades of • Power Transformers, Distribution Transformers • Circuit Breakers • Oil filled switches • X-ray equipment.
Specifications
Eiffel Elect Oil IH Inhibited Transformer oils conforms to and exceed the requirements of ASTM D 3487 Type II & IEC 60296:2012 (Table 2: I – High Grade requirements)
Eiffel Elect Oil IH Inhibited Transformer oils are High Grade Inhibited Transformer oil has superior oxidation stability – meeting the high grade requirements as specified in IEC 60296:2012, high dielectric strength and are used in equipment requiring operations at high elevated temperatures & greater oxidation resistance.
