LUKOIL TRAFO IEC II is an insulating oil that is extremely low in aromatic compounds and is produced from high-quality naphta-based base oils. In addition to that LUKOIL TRAFO IEC II is an inhibited insulating oil with a very low dielectric dissipation factor and a very high breakdown voltage. The low pour point and low-temperature viscosity allow reliable convection and heat dissipation even at very low temperatures
