Product Introduction
Amorphous Metal Transformer is a type of energy efficient transformer found on electric grids. The magnetic core of this transformer is made with a ferromagnetic amorphous metal. The typical material (Metglas) is an alloy of iron with boron, silicon, and phosphorus in the form of thin (e.g. 25 µm) foils rapidly cooled from melt. These materials have high magnetic susceptibility, very low coercivity and high electrical resistance. The high resistance and thin foils lead to low losses by eddy currents when subjected to alternating magnetic fields. On the downside amorphous alloys have a lower saturation induction and often a higher magnetostriction compared to conventional crystalline iron-silicon electrical steel.

Features
*Low loss: Using amorphous alloy strip as the core material can significantly reduce no-load loss and improve energy efficiency.
*High saturation magnetic induction intensity: It has a high saturation magnetic induction intensity to ensure stability under high load conditions.
*High temperature stability: It can still maintain good performance in high temperature environments and adapt to various working conditions.
*Compact structure: The fully sealed structure design delays the aging of transformer oil and insulation paper and reduces maintenance requirements.
Strengths
• Long lifespan
The amorphous metal transformer adopts a fully sealed structure, which can delay the aging of transformer oil and insulation paper. It is not only compact in structure, but also has the advantages of high operating efficiency and maintenance-free. Due to the low loss, low heat generation and low temperature rise of the amorphous alloy transformer, its operating performance is very stable. In addition, the low-voltage winding adopts a foil winding design, which has low loss, strong short-circuit resistance and advanced structure.
• Environmental protection
Amorphous alloy core can effectively reduce the emission of harmful gases such as CO, SO, NO, and reduce the degree of air pollution.
• Energy saving
The no-load loss of amorphous alloy transformer is much lower than that of traditional transformer, which saves energy significantly. Because amorphous alloy materials have excellent magnetic conductivity, the energy consumption of magnetization or demagnetization is extremely low. Therefore, in areas with large fluctuations in power load (such as roads, urban infrastructure and residential areas), the energy-saving benefits of amorphous alloy transformers are particularly obvious.
