Single Phase Column Type On Oil-Immersed Power Transformer

Single-phase transformers are widely used as distribution transformers in western developed countries, southeast Asia, north and south America. In the distribution network with decentralized power supply, single-phase transformer has significant advantages as a distribution transformer. It can reduce the length of low-voltage distribution lines, reduce line losses and improve power supply quality. It adopts a high-efficiency energy-saving wound iron core structure design. The transformer is characterized by adopting pole mounting type suspension installation method, small volume, small infrastructure construction investment, reduction of low-voltage power supply radius and can reduce low-voltage line losses by more than 60%. The transformer adopts a fully sealed structure with strong overload capacity, high reliability in continuous operation, 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 pole mounting type distribution lines for energy saving reconstruction in railway and urban power grids.

It can run with single-phase or by composing three sets into three-phase.
