Oil-Immersed vs. Dry-Type Transformers: Which One Is Better for Your Project?

Can’t decide between oil-immersed and dry-type transformers for your power project? Whether you’re working in the Middle East, Central Asia, Africa or other regions, picking the right type will ensure stable power supply and lower costs.

Jiangsu Unita Electric Equipment Co., Ltd supplies both oil-immersed and dry-type transformers, two common types of 3-phase distribution transformers for global markets. We have rich export experience to the Middle East, Central Asia, Africa, South America, Southeast Asia, Europe and the US, helping clients choose the best fit.

Oil-immersed transformers use oil for heat dissipation, durable and suitable for outdoor large-scale projects—perfect for hot areas like the Middle East and Central Asia. They have long service life and low maintenance needs, ideal for remote power grids.

Dry-type transformers are non-flammable and safe, no oil leakage risk. They’re great for indoor use, such as factories, malls and high-rises, which is popular in Southeast Asia and urban areas of South America.

Choose oil-immersed for outdoor, large projects; pick dry-type for indoor, safe-required scenarios. We offer high-quality products meeting international standards and customized solutions. Contact us to find the right transformer for your project
