Nanocrystalline Transformer Core has very high permeability, high saturation induction, low coercivity, low core loss. Suitable for high frequency transformer of inverter welding equipment, solar inverter, and high power transformer in Kw range.
Nanocrystalline strips have high saturation induction, high permeability, and high Curie temperature, low loss, etc. Its saturation induction is 3 times as that of ferrite, which can output 2 times of the power in the same core sizes. The transformers with the nanocrystalline cores have a better overload tolerance. The loss is only a half to a fifth of that ferrite counterpart in the frequency range of 20 kHz and 50 kHz. The permeability is above ten times of that of ferrite, that makes small exciting current required, and as a result, small copper loss. The Curie temperature is three times of that of ferrite that makes high thermal tolerance of the transformers to the environment.Features:Material: Fe-based Nanocrystalline coreSaturation flux density induction: 1.25TPermeability @ 10KHz: > 20000Curie temperature(℃): 560Stacking factor: 0.78Saturation magnetostriction(*10^-6): <2Resistivity (μΩ.cm): 90Ribbon thickness: 25μmCore shapes: Toroidal coreHigh saturation flux density – you can reduce volume of transformers vs tranditional FerriteHigh permeability – improve efficiency,lower exciting power and reduce copper lossLow coercivity and Low core loss – low temperature riseExcellent thermal stability – working temperature of -40 – 130℃Application:Inverter welding machinesElectrolytic plating power suppliesHigh Power Laser power suppliesCommunication, high-speed railway power suppliesHigh frequency heating systemsHigh frequency nd high power switched mode power supplyCraftsmanshipNanocrystalline 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 powergrid equipment.
