Amorphous core transformers are manufactured using ferromagnetic amorphous metal formed into thin foils. Their higher resistance and thinner foils have been proven to lead to low losses and better resistance to harmonic wave. The use of amorphous metal transformers gradually gained popularity, particularly throughout India and China who have been using them since about 2005. Europe and the USA have been slightly more cautious to use this type of transformer, due in part to the higher labour costs of production. Typical Applications: Transformers for electric grid power and distribution Current transformers High frequency, energy storage inductors Saturable cores Motors Invertors High-frequency electronic devices GFCI’s (Ground Fault Circuit Interrupters) Advantages of using amorphous cores: High permeability High magnetic density Reduced distribution and core losses Wide range of frequency properties Low coercivity forces Low no-load loss Low temperature rise Affordably priced Excellent resistance to corrosion High harmonic wave tolerances Craftsmanship Amorphous alloys are formed by adding a certain amount of glass forming agent to the molten metal, and rapidly quenching and casting using a narrow ceramic nozzle under high temperature melting conditions. Amorphous alloys have the similar characteristics of glass structure, which not only make them have excellent mechanical properties, physical properties and chemical properties, but more importantly, the new technology of producing amorphous alloys using this rapid quenching method is less than the cold-rolled silicon steel sheet process. 6 to 8 processes can save energy consumption by 60% to 80%, which is an energy-saving, time-saving and efficient metallurgical method. Moreover, the amorphous alloy has low coercivity and high magnetic permeability, and its core loss is significantly lower than that of oriented cold-rolled silicon steel sheet, and its no-load loss can be reduced by about 75%. Therefore, the use of amorphous alloys instead of silicon steel sheets to manufacture transformer cores is one of the main means to save energy and reduce consumption in today’s power grid equipment.
