single phase pole mounted power electric 25kva transformer


 The Farady overhead transformer may be used alone for the supply of a single phase load or as one of three units in a bank for the supply of a three phase load. The unit may be direct mounted to a wooden or concrete pole, or cluster mounted on a pole for three phase use. Our single phase overhead distribution transformer is commonly used in various places including rural areas, remote regions and scattered villages to provide high quality power supply for daily lighting, agricultural production and industrial plants. Aside from these, it is also suitable for the energy saving projects for railway and urban grid.

In Western developed countries, Southeast Asia, and the 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, which is small in size, small in capital investment, and reduces 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 power distribution lines.
It can be operated in single-phase or three single-phase groups as three-phase operation.
