Shielding Of Power Cables

Conductor shielding:

According to relevant industry standards, cables with rated voltage exceeding 2KV need conductor shielding. Conductor shielding, also known as inner shielding, is used to form a smooth layer on the relatively rough surface of the stranded conductor to reduce the concentration of electric field at the insulation interface.

Copper Wire Shielding or Copper Tape Shielding, Have You Chosen the Right One?

According to different occasions, the cable structure is also different. In the occasion of shielding interference, shielded cables are widely used. So when choosing shielded cables, should you choose copper wire shielding or copper tape shielding?
The function of the shielding layer is mainly to protect the current or signal from external electromagnetic interference. And it avoid the electromagnetic field generated by itself during use to the surrounding environment and current flow failure.

One Minute To Understand The Role Of Cable Shielding

The outer layer of the wire and cable is generally rubber or rubber composite sheath, the function of this layer is to insulate, but also to protect the cable from damage.

The cable is divided into high-voltage or low-voltage cables. If it is high-voltage, there will be a layer of resin-like filler inside, which serves as insulation. In high-voltage cables, this layer is an important part of insulation. There is no such thing in low pressure. Then there will be something like ribbon wrapped inside, which is to fix each core of the cable and fill the gap in the middle.
