    A shielded cable is a transmission line wrapped with a metal mesh braided layer, usually red copper or tinned copper. The shield layer of the shield wire needs to be grounded so that external interference signals can be directed to the earth by this layer. Shielding wire is a kind of wire with metal braid shell specially used to reduce the influence of external electromagnetic field on power supply or communication line. This shielding wire also prevents the electromagnetic energy of the wire from radiating outward. Ordinary cable: insulation layer + shielding layer + conductor. Advanced cable: insulation layer + shielding layer + signal conductor + shielding layer grounding conductor. Application: the shielding layer needs to be grounded, the external interference signal can be introduced to the earth by this layer, to avoid interference signal into the inner conductor interference and reduce the loss of transmission signal. Shielding cables are used to isolate electromagnetic field noise sources from sensitive devices and cut off the propagation path of noise sources. Shielding is divided into active shielding and passive shielding. Active shielding is to prevent noise sources from radiating outward. Passive shielding is designed to prevent sensitive equipment from being interfered by noise sources. Precautions for use: The shielding layer of the shielded wire does not allow multi-point grounding, because different ground points are always different, and there is a potential difference between each point. Such as multi-point grounding, forming a current in the shielding layer, forming a current induced on the wire, forming interference induced on the signal line, not only can not play a shielding role, but the introduction of interference, especially in the frequency converter with more occasions, interference contains a variety of high-order harmonic components, re
