Note:
Samic Elect Oil N-42 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.
Packaging Options:
Samic Elect Oil Inhibited Transformer oils are offered in 200-210 liters 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 drums in an 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
Samic Elect Oil N-42 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.
The above figures are typical of blends with normal production tolerance and do not constitute a specification.
