What should we pay attention to when using shielded wire?

  Shielded wire is widely used in signal transmission. It can not only reduce the influence of external electromagnetic field on power supply or communication line, but also prevent the line from radiating electromagnetic energy. So what should we pay attention to when using shielded wire?
 
  1. The shielding wire and ground wire shall not be broken and shall be screwed into one strand;
 
  2. The braided ground wire of shielding wire shall be as short as possible;
 
  3. The grounding of shield wire and ground wire must be firm and the grounding resistance shall be small;
 
  4. The shielding layer of shielding wire should not be stripped too long, resulting in excessive exposure of signal wire;
 
  5. The shielded wire cannot be grounded at multiple points, because different grounding points are always different, and there is potential difference at each point. The current formed in the shielding layer not only can not play the role of shielding, but also introduces interference. Especially in the occasions where frequency converters are widely used, the interference contains various high-order harmonic components, causing greater impact, which should be paid special attention to.
