Pole Mounted Transformer :

 Pole mounted transformers are used in extensive rural area. These transformers range from 16 kVA to 100kVA and transform 11,000 to 33,000 volts down to a low voltage of 400 volts. Pole mounted transformers are reasonably small in size and mass so that it is easy to install them on single pole structures, and larger units on two-pole structures, approximately 5 meters above the ground. This makes the transformers inaccessible, reducing the risk of injury to animals and people and minimizing vandalism.
