Dry-Type Transformers vs. Oil-Filled Transformers

Transformers are one of two main types, dry and oil filled. Dry types offer many advantages over the oil-filled transformers including environmental problems, fire safety concerns and better maintenance over oil-filled units. In fact, dry transformers have become the most recommended type of transformers for the reasons listed above. Let’s take a look at each reason.
      • Reduced Maintenance Dry-type transformers are solid state and have no moving parts requiring replacement or maintenance, and operate for long times without any issues. There is no oil to be replenished and are produced to ISO 9001:2015 standards for quality.
      • Fire Safety Dry-type transformers offer a safe and proven track record of power and do not require safety precautions like being installed in a fireproof vault or requiring venting of gases like some oil-filled units. Because of these features, dry-type transformers are ideal for high-rise structures, schools, factories, or anywhere fire safety is an environmental concern.

What is a Dry Type Transformer?

Some transformers are cooled by oil to reduce the heat generated within the electric core of the transformer. Dry-type transformers use air to cool the cores and don’t require an oil or lubricant to cool the cores. Our industrial dry type transformers are voltage changing (Step-up or Step-down) and use cooling ducts to allow air flow through the coils for cooling. Acutran will develop a design which meets your specific requirements. Custom connections, mounting arrangements and any other requirements for your application are no problems for our design experts. We will develop a design and quotation, quickly leveraging our extensive design library and design tools. Regardless of your application, requirements or time line, you can rely on Acutran for dependable integrated power magnetic solutions.
