Definitions and Characteristics：
Voltage Reduction: It means that a transformer converts the input high-voltage electrical energy into low-voltage electrical energy.
All-Copper: The windings of the transformer are all made of copper wires, which possess excellent electrical conductivity and mechanical strength.
Three-Phase: It indicates that the transformer has three independent windings and is applicable to three-phase alternating current systems.
Dry-Type: It means that the transformer does not use a liquid cooling medium (such as transformer oil), and usually adopts natural air cooling or forced air cooling.
Working Principle：
Input Voltage: The high-voltage power source is applied to the transformer through the primary winding.
Generating Magnetic Field: The current in the primary winding generates an alternating magnetic field in the iron core.
Transferring Magnetic Field: The alternating magnetic field is transferred to the secondary winding through the iron core.
Inducing Electromotive Force: The alternating magnetic field induces an electromotive force in the secondary winding, generating a low-voltage output voltage.
Output Voltage: The secondary winding outputs the required low-voltage electrical energy for the load to use.
