Robust & Reliable Protection
There are many types of enclosures for dry-type transformers. These enclosures are designed to provide a degree of protection to personnel against access to hazardous parts and to provide a degree of protection to the transformer from contaminants such as moisture, dust, metallic dust, and chemicals. These enclosures are typically specified by a NEMA rating. The most common dry-type transformer enclosures are listed in the table below.
