Overview

In Western developed countries, Southeast Asia, North and South America, a large number of single-phase transformers are used as distribution transformers. In the power distribution network with distributed power supply, single-phase transformers have great advantages as distribution transformers. It can reduce the length of low-voltage distribution lines, reduce line losses, and improve the quality of power supply. It adopts a high-efficiency and energy-saving coiled iron core structure design. The transformer is characterized by a pole-mounted suspension installation method, small size, small capital investment, and reduced low voltage The power supply radius can reduce the low-voltage line loss by more than 60%. The transformer adopts a fully sealed structure, with strong overload capacity, high continuous operation reliability, simple maintenance and long service life.

It is suitable for rural power grids, remote areas, scattered villages, agricultural production, lighting and power use. It can also be used for railways and urban power grids for energy-saving transformation of pole-mounted distribution lines.
