D-30~6300kVA Single-phase oil immersed transformer
In the distribution network with dispersed 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 power supply quality.
- Overview
- Recommended Products
With the design of a high-efficiency and energy-saving wound core structure, the characteristic of this transformer is that it adopts the overhead suspension installation method. It has a small volume and requires a small capital construction investment. It can reduce the low-voltage power supply radius and can reduce the low-voltage line losses by more than 60%.
The transformer adopts a fully sealed structure, has a strong overload capacity, high reliability for continuous operation, simple maintenance, and a 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 the energy-saving renovation of overhead distribution lines in railway and urban power grids.
It has the characteristics of small volume, convenient installation, simple maintenance,low noise, low line loss, high efficiency and energy saving, reliable operation, and strong overload capacity.
Peculiarity
Small in size, easy to install and simple to maintain.
Low noise, low line loss, highly efficient and energy-saving.
Reliable in operation and with strong overload capacity.
