The cable is divided into high-voltage low-voltage cables. If it is high-voltage, there will be a layer of resin-like filler in it, which acts as insulation. In high-voltage cables, this layer is an important part of insulation. Low pressure does have this layer of things. Then there will be something like a ribbon wrapped inside, which is to fix each core of the cable fill the gap in the middle.

What is the function of Guangxi cable shielding layer?

1. Because the current passing through the power cable is relatively large, a magnetic field will be generated around the current. In order to affect other components, a shielding layer can shield this electromagnetic field in the cable.

2. It can play a certain role in grounding protection. If the core wire of the cable is damaged, the leaked current can flow along the shielding laminar. If it is grounded, it will play a role in safety protection.

3. If it is a control cable, there is no difference in others, but in some places, especially the control cable of the computer system, the shielding layer here is used to shield the external influence, because its own current is very weak, it is very afraid of the influence of the external electromagnetic field.
