Dry type transformer are widely used in Chemical, oil and gas industry Environmentally sensitive areas (e.g. water protection areas) Fire-risk areas (e.g. forests) Inner-city substations Indoor and underground substations Renewable generation (e.g. off-shore wind turbines)
A dry type transformer is a type of transformer which never uses any insulating liquid where its winding or core are immerged in liquid. Rather, the windings and core are kept within a sealed tank that is pressurized with air.
Types of Dry Type Transformers The dry type transformer is of two types. They are
What are the main advantages of a dry type transformer? Self-extinguishing, low fire hazard a dry type transformer comes with an eco-friendly material on its insulation. So, it comfortably winds in a self-extinguishing manner, is flame retardant, and of course easy to maintain. With it, you won't have to invest in a fire extinguisher. Plus, even under the influence of arcing, it doesn't produce toxic gases.
Zero Oil Usage as mentioned earlier, the dry transformer doesn't need any liquid to cool. It only requires air to remain cool. So, you won't have to incur extra expenses to get oil, or any other liquid, plus the maintenance costs attached to them. It's safe to say that this is an almost maintenance free transformer, so you can stay worry-free.
Eco-friendly and safe since dry transformers don't use oil or liquids for that matter, you won't have to deal with oil leaks. Or any other form of environmental pollutants. Plus, they are self-extinguishing meaning they rarely explode. Also, the dry type transformers are widely known to withstand unexpected weather changes, making them suitable for heavily polluted and condensed environments.
Low cost installation and lower load losses due to their low risk nature, there are barely any restrictions when installing the dry type transformers. You also won't have to deal with other environmental precautions such as groundwater protection. Also, these transformers can serve you for over 20 years, with low chances of failure.
Low Maintenance we cannot insist on this enough. The dry type transformers are extremely low maintenance. Like you barely have to even maintain them. As long as they have air to cool, you won't have to deal with built-up dirt. Also, you will never have to deal with liquid testing. However, a routine expert inspection is recommended, and that shouldn't be too hard.
Sustainable when you use a dry transformer, you are playing a key role in ensuring we save our earthly resources. With it comes low electricity usage, 90% recyclable materials, and a reliable service of 20+ years.
