DESCRIPTION
A single-phase pole mounted transformer is a special type of single-phase transformer that has a pole mounted shape. It consists of a primary winding and a secondary winding and is primarily used to step up or step down the voltage of AC power.
The single-phase pole mounted transformer typically uses a toroidal core to support and guide the magnetic field. This core is made of a high-permeability material, such as silicon steel, to enhance the efficiency of the transformer and reduce iron losses. The primary and secondary windings are wound around this core and achieve voltage transformation through mutual induction.

Pole-mounted Transformers Feature
Purpose:
Voltage Transformation: Single-phase pole-mounted transformers are used to transform voltage from one level to another, typically stepping down the voltage for distribution to homes and businesses.
Distribution: They are a common component in the distribution network, helping to provide the appropriate voltage levels for end-users.
Mounting:
As the name suggests, these transformers are mounted on utility poles. This allows them to be positioned conveniently along power distribution lines, reducing the need for large structures or dedicated substations.
Construction:
The transformers are housed in weather-resistant enclosures to protect them from environmental factors such as rain, snow, and sunlight.
Cooling may be achieved through natural convection or with the help of cooling fins to dissipate heat.
Phases:
Single-phase transformers handle power in a single alternating current (AC) waveform. In contrast, three-phase transformers handle three AC waveforms and are often used in larger industrial settings.
Capacity:
Single-phase pole-mounted transformers come in various capacities, ranging from a few kilovolt-amperes (kVA) to several tens of kVA, depending on the specific requirements of the distribution area.
