The effect of sharing the shielding layer of the power cord

1. The current through the power cable is relatively large, so a magnetic field will be generated around the current. In order not to affect other components, the addition of a shielding layer can shield this electromagnetic field in the cable.

2. It can play a certain grounding maintenance effect. When the cable core wire is damaged, the outflowing current will shield the laminar flow such as the grounding grid, which has the effect of maintenance.
