Huawan pole mounted distribution transformer is designed for efficient overhead power distribution in rural and suburban areas. These pole type transformers reliably step down medium voltage (MV) to usable low voltage (LV) for residential and commercial customers. Engineered for durability and easy installation on utility poles, they offer a compact, space-saving solution with minimal ground footprint, ensuring safe and stable electricity supply.

Working Process of Pole Mounted Transformer

Based on the principle of electromagnetic induction, the HV winding generates an alternating magnetic field in the iron core, which transfers energy to the LV winding and realizes the step-down conversion from high voltage to low voltage.

The standard low-voltage electric energy output by the LV winding is distributed to the LV overhead lines or cable networks within the distribution transformer area through devices such as LV outgoing terminals and isolating switches.

During operation, the protective devices on both the HV and LV sides continuously monitor the current and voltage parameters, and will act automatically to disconnect the faulty circuit in case of abnormal conditions such as overload, short circuit and overvoltage.

The transformer maintains its internal oil temperature and winding temperature within the safe operation range through the natural heat dissipation of iron core losses and winding losses, as well as the heat dissipation structure of the housing, so as to ensure stable operation.

When the load changes, the transformer can adjust the winding turns ratio through the tap changer (if equipped) to ensure the stability of the output voltage on the LV side and meet the power consumption requirements of different loads.

The Role of Pole Mounted Transformers in Distribution Systems



Core Voltage Conversion

Converts medium-voltage (10kV/20kV) power to low-voltage (220V/380V) levels, serving as the key "last mile" device for compliant power supply to terminal loads.



Flexible Load Distribution and Deployment

Enables flexible on-pole installation without dedicated rooms, balancing terminal load density to avoid local overload/voltage sag and improve network planning flexibility & operational efficiency.



Terminal Power Supply Protection and Stabilization

Integrates fuses and lightning arresters to quickly isolate faults and prevent propagation, while stabilizing LV-side output voltage to ensure the continuity and quality of terminal power supply.
