three phase double winding amorphous alloy transformer

- Extremely Low Loss, Energy-Saving Features, High Power Consuming Efficiency;

- Amorphous Metal Materials are advantageous in that: They just need to consume lesser energy in material manufacture and with their extremely low losses, power is saved in a large sum, thereby greatly reducing the power plant output, or relatively lowering waste gas (CO2, SO2) emission, lessening both environmental pollution and greenhouse effects, and realizing a maintenance free and contamination free state;

- Low in Operating Temperature, Tardy in Insulation Aging, and Long in Transformer Life;

- High Overload Capacity, High Mechanical Strength;

- Amorphous Cores are featured in that: When a magnetic flux pass through amorphous cores in a rather high frequency, these amorphous cores may remain a low iron loss and a low exciting current, which may not result in core saturation. Consequently SBH15 amorphous alloy transformers made from amorphous cores possess a rather fine resistance to harmonic waves;

- Rapid Investment Recovery
