Shielded Cables are a special type of cable that shields the insulation around a cable to reduce electromagnetic interference (EMI), allowing external electromagnetic radiation and magnetic field radiation to enter directly without disturbing the inner wire.
The shield of a typical shielded cable is braided into a mesh by tinned copper and covered with a conductor insulation to form a shield. When the electromagnetic field with a high frequency outside the environment passes through the shield, a vortex is generated and is lost, thereby achieving anti-interference Role, to ensure safe and stable signal transmission cable.

There are two layers of shielded cable also called shielded cable double shielded cable mesh braid radiation is anti-magnetic field, the general use of tin-plated copper as a woven material; aluminum foil layer is used to prevent electromagnetic radiation. More importantly, the shield must be completely grounded, so that the interference current can be effectively introduced into the ground, thus providing a good shielding effect.

The meaning of shielding against flexible cables needs to be addressed by EMC electromagnetic compatibility (for details, please click on the link above to read). For example, in the case of signal cables or control cables, the signals are weak signals and the weak signals are easily interfered. Therefore, in most cases, the signal cables or control cables are shielded. However, there are a few cases where the signal cables Or control cable unshielded, then there is a condition: that is near the electromagnetic environment is very "clean." For the power cable, because it is a strong current to go is not afraid of interference, so the power cable itself, it is not required to shield, but if the distribution of power cables around the scene sensitive to electromagnetic equipment or components, Then the shielded power cable should be used, its purpose is to prevent the power cable work out of electromagnetic radiation and interfere with other devices or components around.
