What is a Pole Transformer?
A pole transformer is a small transformer installed on a utility pole, primarily used to convert high-voltage electricity into low-voltage electricity suitable for residential and commercial use. It typically consists of an iron core, windings, and insulation materials, and is cylindrical or square in shape, installed in the upper middle part of the utility pole. This design saves ground space and is suitable for power distribution needs in both urban and rural areas.
How a Pole Transformer Works
Voltage Conversion: Converts 10kV high-voltage electricity to 220V or 380V low-voltage electricity through the principle of electromagnetic induction.
Heat Dissipation Design: Relies on natural air convection or oil immersion cooling for heat dissipation.
Protection Functions: Built-in fuses or circuit breakers prevent overload and short circuits.
Installation Characteristics: Directly fixed to the utility pole, approximately 5-8 meters above the ground.
