The iron core adopts a kind of material with outstanding magnetic conductivity performance, and adopts the internationally advanced ultra-rapid cooling technology. The rapid quenching and solidification production process directly cools the liquid metal at a cooling rate of 106°C/S to form a solid thin strip with a thickness of 0.02-0.04mm to obtain an amorphous alloy structure with the characteristics of short-range order and long-range disorder in the atomic arrangement and combination. A typical amorphous alloy contains 80% iron, and the other components are boron and silicon. It is a soft magnetic material with small magnetization power and no structural defects that prevent the movement of domain walls.

The buried transformer and the billboard-type low-voltage form two parts on the ground and underground, which do not occupy surface space, especially suitable for densely populated central cities.

Due to seasonality, personnel mobility, and diurnal time differences of residential users, the load fluctuation of the power distribution network in China’s power distribution network is relatively large, and the capacity of the distribution transformer does not match the electricity demand. Generally, more than 70% of the time of the special transformer of enterprises runs no-load or light-load, and more than 80% of the time of the public transformer used by residents runs no-load and light-load, resulting in relatively high loss of the distribution transformer.

The structure is more reasonable, the performance is more excellent, the manufacturing cost is lower, and it is a new high-reliability and energy-efficient product. This product breaks through the traditional planar structure and adopts a three-phase symmetrical three-dimensional structure.

The core adopts high-quality high-grade cold-rolled silicon steel sheet, and the coil wire adopts high-quality oxygen-free copper.

This product is the perfect combination of amorphous alloy core and resin-insulated dry-type transformer, and it is a new energy-saving transformer. It has the energy-saving effect of amorphous alloy core and also has the characteristics of resin-insulated dry-type transformer.
