Structural Features
1. Ultra low loss , energy and high electricity efficiency --- loss saving 70% compared with the traditional transformer no-Load electricity consumption;
2. Three column amorphous core,adopting the invention patenttechnology which has Ultra low working noise and solve thoroughly high working noise;
3. Low energy consumption and low loss characteristics of amorphous materials can save power consumption .reduce thepower generation, decrease relative S02 and C02 exhaustemission, reduce environmental pollution and greenhouse effect, it is maintenance free and zero pollution;
4. Low working temperature,the full load operating temperature less than 70℃,the insulation degradation slow so that the service life is long very much;
5. High overload capacity,high mechanical strength;
6. The amorphous core retain has the characteristics of low ironloss and low magnetizing current when passing high frequencyflux, so it will not cause core saturation and posses good harmonic resistance;
7. Fast capital recovery.
