High performance uninhibited electrical insulating oil MAK Hivoltol is a high quality mineral uninhibited electrical insulating oil. It is manufactured from severely hydrotreated low aromatic oil and does not have polar compounds. It has very good dielectric property, high resistance to oxidation and aging. It has excellent low temperature property, low viscosity and provides efficient heat transfer. MAK Hivoltol has a high resistance to thermal and chemical degradation and offers very high breakdown voltage. Special care is taken to achieve very low water content in the oil. It is noncorrosive towards copper and does not require passivation.
IS 335:2018 (Type II) – Uninhibited
It is used as a quenching media for power and distribution electrical apparatus such as transformers, switch gears, circuit breakers, capacitors and other allied equipment.
