Product Description

Product Description
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.

Product technical parameters and external dimensions



Product features 
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.



Environment condition

1. Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h.
2. Install and use indoors. Altitude above sea level for operation site should not exceed 2000M.
3. Relative humidity should not exceed 50% at max temperature +40. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20. But in view of the temperature change, it is possible that moderate dews will produce casually.
4. Installation gradient not exceed 5.
5. Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components.
6. Any specific requirement, consult with manufactory.
