What Is a Pole Mounted Transformer?
A pole mounted transformer is a type of distribution transformer installed on a pole, typically made of wood or concrete, at the height of overhead electrical wires. Its main job is to step down the high voltage from utility power lines (often between 11kV–33kV) to the safer, lower voltages used by homes and businesses, usually 120/240V.
Key Components
🧲Core and Windings: Laminated silicon steel core with copper or aluminum windings for energy transfer.
🛡️Transformer Tank: A robust, weatherproof steel enclosure.
🌬️Cooling System: Oil or air-based cooling for safe operation.
🔌Bushings: Insulation for wires entering and exiting the tank.
🛑Surge Arresters & Fuses: Protective elements against voltage spikes and overcurrent.
🔩Mounting Brackets: For secure pole installation.

How Does a Pole Mounted Transformer Work?
The transformer operates on electromagnetic induction. High-voltage alternating current enters the primary winding, creating a magnetic field that induces a lower voltage in the secondary winding. This process allows the safe and efficient delivery of electrical power directly to residences, commercial buildings, and industrial sites.
