Pole mounted transformers are common breadbox transformers used for converting distribution voltage to a 120/240 volt power source used by homes and small businesses.
With exposure to harsh climate conditions and situated in remote areas, reliability has been built into the specification of these electrical transformers. Tanks are shaped to reduce accumulation of water and corrosive materials. Protective coatings are applied to tanks to reduce corrosion. In the coastal regions tanks are zinc sprayed. In highly corrosive areas tanks are made from Stainless or 3CR12 steel.
