What is telephone pole transformers?

Telephone pole transformers, also known as distribution transformers, are devices that transfer electrical energy between circuits at different voltage levels. They are typically mounted on utility poles or streetlight poles in residential and commercial areas.

The primary voltage of a telephone pole transformer is typically between 4,160 and 34,500 volts, while the secondary voltage is usually below 600 volts. The transformer is designed to step down the high voltage electricity from the power lines to a lower voltage that can be used by homes and businesses.

Telephone pole transformers are typically small and rectangular in shape, ranging in size from a couple of cubic feet to about six feet in height. They are made of a steel shell with aluminum or copper windings wrapped around an iron core. The shell is typically filled with oil, which helps to cool and insulate the transformer.

Telephone pole transformers are critical components of the electrical distribution system, as they ensure that the electricity provided to homes and businesses is safe and reliable. They are also designed to be durable and require very little maintenance over their lifespan, which can last up to 30 years.
