UPGM205 with high peformance tensile used in Transformer
.
The electric reactor is also called the inductor ,after the electric reactor is energized, the magnetic field can be generated in a certain space range which plays a protective role in the power transmission and distribution.The transformer utilize the electromagnetic induction to change the voltage of the alternating current, and it acts as an energy conversion process.
