It is manufactured from judiciously selected blend of latest technology feed stocks, which  is highly suitable for all grades of Power & distribution Transformers, Circuit Breakers, Oil filled switches and X-ray equipment.

Product Description & Specifications

Features & Benefits

  • 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.

The above figures are typical of blends with normal production tolerance and do not constitute a specification. Packaging Options: Zeal Elect Oil N-42 Un-inhibited Transformer oils are offered in 200-210 litres of steel drums and also in bulk in Flexi bags or ISO tanks. Storage Precautions:: Extreme care is taken while packing these products, including filling of drums in inert atmosphere, as Electrical Insulating oils / Transformer oils are very sensitive to very minute concentrations of contaminants, such as moisture, particulate matter, fibers, etc. Hence, care should be taken to store Zeal Elect Oil N-42 Un-inhibited Transformer oil in a clean and dry condition. It is strongly recommended that all storage tanks / drums be maintained such that oil is not in contact with atmospheric air. Also these oils should always be stored indoors in climate controlled environments.
