The 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.
Due to the small magnetostriction coefficient of the amorphous alloy core, the transformer operates at a lower noise level (usually 5–10dB lower than traditional products). Making it suitable for noise-sensitive environments like hospitals and residential areas.
Amorphous alloy exhibits excellent magnetic permeability, achieving high magnetic flux even under low magnetic field strength. This optimizes the transformer's load loss and improves energy conversion efficiency.
The core material has better heat resistance and mechanical strength, enabling it to withstand current surges exceeding the rated load for a short time. This reduces maintenance costs and extends equipment life.
Low-loss and low-heat characteristics slow down component aging, allowing a design life of over 20 years. The material is also recyclable, complying with green power grid requirements.
Preferred equipment for urban and rural distribution network construction/renovation and new energy grid connections (solar PV stations and wind farms).
Ideal for industrial parks, manufacturing factories, and large commercial complexes requiring 24-hour continuous power supply.
Perfect for residential communities, hospitals, schools, and libraries where noise control and long-term energy efficiency are priorities.
Widely used in data centers and remote off-grid systems where high stability and maximum efficiency are required.
