ADVANTAGES OF AMORPHOUS ( WHY AMORPHOUS )
- Small lightweight transformer to reduce direct material cost
- The equipment is simple and fast, and the production capacity is greatly improved.Low noise effect
- Low noise effect
- Compared with the silicon steel sheet transformer of the same capacity voltage grade, the no-load loss is reduced by 70% and the no-load current is reduced by about 75%. The energy saving effect is obvious.
