Why use a dry type transformer?
Dry-type transformers are ideal for small and medium-voltage uses that can accommodate both indoor and outdoor facilities. By using natural air as a cooling medium, they are less hazardous and have a lower risk of fire disruption. Air-cooled systems also need less maintenance and offer simple installation.

How do dry transformers work?
A dry type transformer is termed as “voltage changing,” which signifies that in this type the air gets cooled rather than cooling the liquid. The case in which the transformer is placed has proper ventilation; hence proper ventilation results in cooling of coils due to the air inside the case.
Can dry type transformers be used outside?
When using a dry type transformer outside, be sure to consider the mounting location and enclosure rating. Standard rating for indoor transformers. Never to be used outside. Our top preference is to mount transformers indoors, in which case this would be the acceptable enclosure.
Can you hang a 75 kVA transformer?

What is the difference between dry and oil transformer?
Dry-type transformers use air as the cooling medium, while oil-filled transformers use oil instead of air. Some public places do not use oil-filled transformers because they are considered to be a big fire hazard and, instead, use dry-type transformers. This is because the liquid being used is flammable.
