Henan GNEE Electric Co., Ltd. is one of the most reliable manufacturers and suppliers of single phase pole mounted distribution transformer in China. If you're going to buy customized single phase pole mounted distribution transformer made in China, welcome to get quotation from our factory. Quality products and reasonable price are available.

 

Single-phase pole-mounted transformers are used as distribution transformers. They have great advantages in the distribution network using distributed power supply. They can reduce the length of low-voltage distribution lines, reduce line losses, and improve power supply quality.
The transformer adopts an efficient and energy-saving coiled core structure design and a pole-mounted hanging installation method. It has a small size, small infrastructure investment, reduces the low-voltage power supply radius, and can reduce low-voltage line losses by more than 60%. It is suitable for rural power grids, remote mountainous areas, scattered villages, and agricultural production lighting electricity.

Pole mounted distribution transformer 

singel phase pole mounted distribution transformer Structural characteristics

1. The high-voltage coil is wound with high-quality polyurethane enameled round copper wire, and the low-voltage coil is wound with cable paper-covered wire. Dispensing paper is used for interlayer insulation. During the drying process of the coil, it begins to melt at a certain temperature, resulting in adhesion, and starts to solidify as the temperature rises, so that the adjacent layers of the winding can be reliably bonded into a fixed unit , to prevent the coil winding displacement, thus ensuring the safety and reliability of the insulation structure.

2. Iron core

The single-phase coil core is made of grain-oriented silicon steel sheet or amorphous alloy silicon steel sheet, which can ensure that the magnetic flux flow direction is consistent with the grain orientation of the silicon steel sheet, so that the excellent performance of the material can be fully exerted, and the no-load loss is far away. Below standard requirements, and fastened with a special core curing paint, it further effectively reduces the noise level of the transformer.

3. The cylindrical fuel tank is used, and the fuel tank adopts a fully sealed structure, which enhances the reliability of operation and is maintenance-free for normal operation.
