Our oils for transformers

Power outage is one of the most critical threats to the functioning of our society. Forming the backbone of modern energy grids, transformers need to be absolutely reliable to ensure a stable and resilient power supply at all times.

The growing concern about the reliability and efficiency of electric grids has been fostering the use of alternative insulating fluids that both improve transformers' safety and lifetime without damaging the environment. 

As part of our commitment to better energy, TotalEnergies Lubricants is one of the very few suppliers that offer a comprehensive range of conventional and alternative transformer oils to support grid stability and electric infrastructure modernization.

Our dielectric fluids and insulating oil: ISOVOLTINE

ISOVOLTINE oils are extremely effective in their ability to insulate components of the transformer and ensure efficient cooling in the system. In addition, they enable outstanding protection against oxidation and prevent wear of the core, windings and other insulating materials.

ISOVOLTINE offers superior insulating properties due to high dielectric breakdown voltage, volume resistivity, interfacial surface tension and absence of polar substances.

This range also provides outstanding resistance to oxidation, very high purity levels which minimize power factors and help prevent temperature rises, excellent cooling properties due to good fluidity and heat transfer capacities, and an efficient protection of equipments due to non-corrosive nature and cleaning properties.

Our biodegradable lubricants for transformers: ISOVOLTINE BIO

Alternative fluids are on the rise all over the world not only because of their green image. Ester-based dielectric fluids have now proven track records in distribution and power transformers.

The technical capabilities of esters are nearly unlimited, their financial benefits already measurable for equipment manufacturers that can streamline the design of their transformers and provide cost savings to end-users.
