IFP Transformer Oil is highly refined electrical insulating oil developed for use in oil-immersed transformers, capacitors, tap changers and circuit breakers where the equipment manufacturer specifies a Type II inhibited oil meeting ANSI/ASTM D3487-09 requirements.

Transformer Oil is formulated with hydro treated naphthenic base oils and an oxidation inhibitor to control sludge and deposit formation and provide extended service life compared with non-inhibited Type I transformer oils. It has a high dielectric strength and low power factor to provide excellent insulating properties. It has excellent low-temperature properties and is noncorrosive to copper and copper alloys. This product does not contain any PCBs.


  • Excellent insulating properties
  • High dielectric strength & low power factor
  • Resists oxidation and deposit formation
  • Excellent low-temperature properties
