A pole-mounted transformer is a type of electrical transformer that is mounted on a utility pole. Typically, these transformers step down the voltage from the high-voltage power lines to the lower voltage used by homes and businesses.
Pole-mounted transformers are usually enclosed in a metal cabinet or box, and they may have either a single phase or three phases. The primary winding of the transformer is connected to the high-voltage power line, while the secondary winding is connected to the lower-voltage distribution system.

Pole-mounted transformers are typically used in areas where underground utilities are not possible or practical, such as in rural areas. These transformers are also used in urban areas when space is limited, such as along busy streets.
Benefits of a pole-mounted transformer
There are many benefits to having a pole-mounted transformer. Perhaps the most obvious benefit is that it makes it easy to access the transformer for maintenance or repair.
Additionally, pole-mounted transformers are typically more efficient than those that are ground-mounted because they have less resistance to heat loss.
Pole-mounted transformers also tend to be more durable, as they are less likely to be damaged by flooding or other natural disasters.
How to choose a pole-mounted transformer
When choosing a pole-mounted transformer, there are several factors to consider.
The first factor is the voltage rating. The voltage rating is the maximum amount of voltage that the transformer can handle. It is important to choose a transformer with a voltage rating that matches the voltage of the electrical grid in your area.
The second factor is the size of the transformer. The size of the transformer will determine how much power it can distribute. Transformers come in a variety of sizes, from small units that can power a single home to large units that can power an entire city block.
