Oil Filled Transformer Market Outlook:
Oil Filled Transformer Market size was over USD 45.1 Billion in 2025 and is anticipated to cross USD 83.87 Billion by 2035, growing at more than 6.4% CAGR during the forecast period i.e., between 2026-2035. In the year 2026, the industry size of oil filled transformer is assessed at USD 47.7 Billion.
The major element to dominates the market revenue is the growing demand for electricity. Over the previous 50 years, the total amount of electrical power consumed globally has risen gradually, and in 2021, it was expected to reach over 25,299 terawatt-hours. The transformer enables energy to effectively travel through it without harming the wire; this power is generated either by an engine or a generator.
Moreover, long-distance transmission of electricity produced by oil-filled transformers is also possible; this enables the provision of energy reaching areas that are not served by wires or generators without the need for costly and time-consuming significant building projects. Hence, the adoption of oil-filled transformers is estimated to grow.
