Under the high frequency magnetic field, a shield can generate eddy current, and then a magnetic field is created by the eddy current. This magnetic field has an opposite direction when compared with the original magnetic field, which can neutralize the original field and reduce the interference. Meanwhile, the shield is connected to the ground, so electric field screening is also achieved.
The above technique is called shielding technology, and it is adopted by our metal shielded power cable. As a result, our product shows strong resistance to lightning stroke as well as electromagnetic interference, and the power supply quality is also improved. This product is manufactured according to the enterprise standard, and it is used to deliver electricity in power line whose rated voltage is 0.6/1kV or lower.
