Dry type is specified for use in buildings and near buildings, simply because they are environmentally safer. Dry type transformers are less flammable and pose less of a fire risk, making them ideal for shopping malls, hospitals, residential complexes and other commercial areas.
What is the difference between oil type and dry type transformer?
As the terms suggest, oil-type transformers use flammable liquids (usually mineral oil but can also be hydrocarbons or silicone for other liquid types). Dry-type transformers do not use flammable liquids and rely on robust insulation to promote cool operating temperatures.
What is the difference between wet and dry transformer?
A wet-type power transformer is smaller and more efficient than dry products. Liquid-filled transformers are suitable for indoor use because operating noise is lower. These transformers last longer than dry-type products. Numerous recycling options are available.
Can dry type transformers be used outside?
Dry-Type Transformers suitable for indoor and outdoor applications anywhere that safe and dependable power are important. Cooling ducts in the windings allow heat to be dissipated into the air. Dry-types can operate indoors under almost all ambient conditions for commercial buildings and light manufacturing facilities.
What is dry type transformer?
What is a dry-type transformer? Unlike their liquid-filled counterparts, dry-type transformers do not incorporate liquid to dissipate excess heat and meet temperature classification requirements. Instead, the coils within a dry-type transformer are constructed of a gaseous or dry insulation medium.
What is the advantage of dry type transformer?
Advantages of Dry-type Transformers Air-cooled transformers are practical for low- and medium-voltage sites. Dry-systems eliminate environmental risks related to leaks and spills. Cast coils outperform conventional transformers in extreme conditions.
How do you tell if a transformer is dry or wet?

What is difference between dry type transformer and oil type transformer?
There are two types of transformers being used in the industry currently: Dry-type transformers and oil-cooled transformers. Dry-type uses air as a cooling medium, and liquid cooled uses oil. Oil filled transformers have a higher standard energy efficiency, and as a result have a higher lifespan than dry type.
