Transformer oil, also known as electrical insulating oil, is a specialised fluid used in oil-filled electrical transformers and certain switchgear equipment. It provides electrical insulation between internal components and transfers heat away from windings and other parts, helping prevent overheating. High-quality transformer oil must maintain dielectric strength, oxidation stability and suitable viscosity. Its performance is assessed against recognised specifications, such as IEC 60296, which covers unused and recycled mineral insulating oils.
Engineered for demanding electrical substations and industrial switchgear, our transformer oil delivers reliable dielectric breakdown resistance, accelerated heat dissipation, and long-term chemical stability.
Provides robust electrical insulation between energized components, core laminations, and windings, preventing arcing, flashovers, and dielectric breakdown under high-voltage loads.
Circulates effectively to transfer thermal energy away from transformers, copper windings, and magnetic cores, maintaining low operating temperatures and preventing localized hot spots.
Resists oxidation, acid buildup, and insoluble sludge formation under prolonged thermal and electrical stress, prolonging fluid life and preserving transformer insulation integrity.
Rigorously tested and assessed against recognized international standards including IEC 60296, governing unused and recycled mineral insulating oils for power transformers and switchgear.
