Insulating transformer oils are used to isolate and cool the active parts of electrical transformers. Their regular analysis also provides crucial information on the status of transformers and possible malfunctions.

The characteristics of mineral oils are defined by IEC 60296 (edition 5, 2020) and ASTM D 3487 - 2016.

A distinction is made betweenb inhibited oils, which contain an antioxidant additive, and uninhibited oils.

In France, most insulating oils are uninhibited.

We offer uninhibited insulating mineral oils meeting the IEC 60295 standard, available in drums for deliveries throughout the French territory.
