Dry-type transformers, lacking oil, eliminate risks of fire, explosion, and pollution. Consequently, electrical codes and regulations do not require them to be housed in separate rooms. 

Losses and noise have been reduced to unprecedented levels, paving the way for co-locating transformers and low-voltage switchgear within the same distribution room.

Dry-type transformers employ two cooling methods: natural air cooling (AN) and forced air cooling (AF). Under natural air cooling, the transformer can operate continuously at rated capacity for extended periods.

 With forced air cooling, the transformer's output capacity increases by 50%. This configuration is suitable for intermittent overload operation or emergency overload operation during accidents.
