GNEE Steel power supply transformers
A power transformer is an electrical device that converts alternating power from one voltage to another. Because there are no rotating or moving components a transformer is usually modeled as a stationary device.
In the majority of cases, power transformers are used to "step down" voltage from a higher level to a lower level to make the power usable in factories, offices, and homes. Their main purpose is to make electricity safer and more efficient to be used in a wide array of electrical machines and appliances by regulating the voltage as needed.

Single Phase Power Transformers Feature
1. Ultra-low loss characteristics, energy-saving and high power efficiency;
2. The low energy cost and ultra-low loss characteristics in the manufacture of amorphous metal materials can greatly save the power consumption and reduce the power output of power plants, relatively reduce the emission of C02 and S02 waste gas and reduce the environmental pollution and greenhouse effect, it is maintenance-free and pollution-free;
3. Low operating temperature, slow insulation aging and long service life of transformer;
4. High overload capacity and high mechanical strength;
5. The amorphous core still has the characteristics of low iron loss and low excitation current when it passes through high frequency magnetic flux without the saturation of the core, therefore, the amorphous alloy transformer made of amorphous core has good harmonic resistance.
