Features of Single Phase Pole Mounted Distribution Transformer

1. Key Advantages of Single-Phase Pole-Mounted Distribution Transformers

(1) Material Saving & Lower Lifecycle Cost

• Compared with three-phase transformers of the same capacity, it uses 20% less iron and 10% less copper.
• Adopting a wound core structure further reduces no-load loss by ≥15%, lowering both manufacturing costs and long-term operating costs for optimal lifecycle economics.

(2) Reduced Line Construction Investment

• Using a single-phase power supply system saves 33%–63% of wires (42% by economic current density, 66% by mechanical strength).
• Particularly valuable for street lighting and residential power supply in rural and urban areas, significantly cutting the overall transmission line construction budget.

(3) Adaptable to Modern Production & Flexible Application

• Simple structure enables large-scale modern production, facilitating quality and efficiency improvement, as well as the adoption of new technologies, materials, and processes.
• Lightweight design allows flexible pole-mounted installation, enabling deep placement into load centers. This shortens low-voltage main line distances, reduces line loss (80% of line loss occurs on 20% of main lines), and improves power supply quality.
• Small-range power supply limits fault spread, enhancing power supply reliability. It is also easy to install, maintain, and can be used in single-phase or three-phase configurations.

(4) Construction Investment Advantages (Context-Dependent)

• In light-load areas, a single-phase power supply system reduces construction investment.
• Note: In large-load areas, transformation requires higher economic input—more high-voltage line investment to reach load centers, higher total losses from multiple small-capacity transformers, and greater purchase costs compared to one large-capacity three-phase transformer.
• Foreign application reference: Suitable for regions with high residential electricity consumption (e.g., each household or several households using one unit), where the investment is deemed worthwhile despite higher upfront costs.

2. Core Application Scenarios

• Rural power grids: Ideal for scattered residential loads and street lighting.
• Urban low-voltage distribution: Suitable for residential areas, small commercial districts, and street lighting systems.
• Light-load scenarios: Places with low and distributed power demand, where flexibility and cost-saving are priorities.
