- Commodity name: Three Phase Amorphous Transformers
Amorphous alloy is a new type of strip material. Amorphous alloy material has no crystal structure, small magnetizing power and high resistivity, so the eddy current loss is small. The transformer connection group uses Dyn11 to avoid the influence of higher harmonics, and has a strong ability to withstand unbalanced loads, which significantly improves the power supply quality.

The transformer uses vacuum oiling, which can completely eliminate air bubbles in the coil and ensure stable insulation performance.
Low operating temperature, slow insulation aging, and long transformer life;
High overload capacity and high mechanical strength;
