Single-phase pole-mounted oil-immersed power transformer

Overview

Western developed countries, Southeast Asia, and South America use a large number of single-phase transformers as distribution transformers. In distribution networks with decentralized 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 power supply quality. It adopts a high-efficiency and energy-saving rolled iron core structure design. The transformer is characterized by column-mounted suspension installation, small size, low infrastructure investment, and low voltage reduction. The power supply radius can reduce low-voltage line losses 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 consumption. It can also be used for railways and urban power grids for energy-saving transformation of pole-mounted distribution lines.
