The global Insulating Oil market size was US$ 2968 million in 2025 and is forecast to reach a readjusted size of US$ 3544 million by 2032 with a CAGR of 2.6% during the forecast period 2026-2032.
Insulating oil in an electrical power transformer is commonly known as transformer oil. It is normally obtained by fractional distillation and subsequent treatment of crude petroleum. That is why this oil is also known as mineral insulating oil. Transformer oil serves mainly two purposes one it is liquid insulation in electrical power transformer and two it dissipates heat of the transformer oil. acts as coolant. In addition to these, this oil serves other two purposes, it helps to preserve the core and winding as these are fully immersed inside oil and another important purpose of this oil is, it prevents direct contact of atmospheric oxygen with cellulose made paper insulation of windings, which is susceptible to oxidation.
Global Insulating Oil main players are Nynas, Petrochina, Apar Industry, Ergon, etc. Global top four manufacturers hold a share over 45%. China is the largest market, with a share nearly 30%.
