Dry Type Transformers _
These are basically distribution transformers. Dry type transformers are preferred to oil cooled transformer, in place where there is fire hazards e.g. thickly dense area like Big-Store, Multistory Building, theatres etc. Since these are located near load centers, long line connection and transmission losses are reduced. The higher cost is partly compensated by lower transmission loss, smaller length of conductors and lower losses. Great care must be exerted since live parts are accessible.
