What are the precautions for using shielded wires?

　　The following matters need to be paid attention to when using the shielded wire:

　　The ground wire of the shielded wire cannot be broken: The ground wire part of the shielded wire must be kept intact and cannot be broken. The ground wire should be screwed into one to ensure good conductivity and shielding effect.

　　The braided ground wire of the shielded wire should be as short as possible: To reduce resistance and inductance, the braided ground wire of the shielded wire should be kept as short as possible. This helps to ensure that the shielding layer can effectively introduce the interference signal into the ground, thereby improving the shielding effect.

　　The ground wire of the shielded wire must be firmly grounded: the ground wire of the shielded wire must be firmly grounded, and the grounding resistance should be SMall. This can ensure a good electrical connection between the shielding layer and the earth, so as to effectively introduce the interference signal into the earth.

　　The shielding layer should not be peeled too long: When peeling off the shielding layer, care should be taken not to peel too long to avoid too much signal line exposure. Exposing too much signal line may reduce the shielding effect and even cause signal interference or leakage.

　　The shielded wire cannot be grounded at multiple points: The shielded wire should avoid multi-point grounding because there is a potential difference between different grounding points. Multi-point grounding may form a current in the shielding layer, which not only fails to shield, but may introduce interference. Especially in the case of many interference sources such as frequency converters, multi-point grounding may introduce more high-order harmonic components, which will have a greater impact on the system.

　　In conclusion, in order to ensure the effectiveness and safety of the shielded wire, the above precautions should be followed when using the shielded wire. These precautions help to ensure that the shielding layer can effectively introduce the interference signal into the ground, thereby improving the stability and reliability of the system.
