Amorphous alloy material has an irregular atomic structure, resulting in much lower hysteresis loss than traditional silicon steel sheet cores. Its no-load loss is 30%-70% lower than that of conventional silicon steel transformers, significantly reducing energy consumption.
Due to the small magnetostriction coefficient of the amorphous alloy core, the transformer operates at a noise level usually 5-10dB lower than traditional products. Ideal for noise-sensitive environments like hospitals and residential areas.
Excellent magnetic permeability achieves high magnetic flux even under low magnetic field strength, optimizing load loss and meeting national Level 1 energy efficiency standards.
Better heat resistance and mechanical strength enable it to withstand current surges during peak periods, effectively preventing component aging and reducing maintenance costs.
Low-loss characteristics slow component aging for a 25-year design life. The amorphous alloy material is fully recyclable, complying with green power grid requirements.
