Drawing
How Do Pole-Mounted Transformers Operate
Pole-mounted transformers are installed on concrete poles, allowing
them to transmit generated electricity perpendicularly to the
electrical lines.
To make high voltage more manageable, these transformers reduce it
to 400V.
Engineers often prefer these transformers for their lightweight
design and minimal visual impact.
While larger units necessitate the use of two poles, smaller units
under 5 meters in height can typically be securely mounted on
buildings with just a single pole.
This design helps protect both people and animals from harm, while
also minimizing the likelihood of damage.
