The shielded control cable manufacturer tells you that the electromagnetic noise environment of industrial application sites is often very complicated, and the radiation or conduction (EMI) of electromagnetic noise may seriously interfere with the normal operation of electromechanical equipment. In this process, an important carrier of electromagnetic noise transmission is the various cables used in production line equipment. Some of them are noise sources, and some are disturbed objects. The shielded control cable manufacturer tells you that as a noise source, the cable will spread noise to the surrounding lines and equipment like a radio transmitting antenna; as a victim, the cable will absorb the noise interference from other radiation sources like a receiving antenna.

To combat electromagnetic noise interference on electrical circuits, a very important way is to use shielded control cables.
A shielded control cable is a cable in which one or more wires (insulated from each other) are wrapped by a common conductive layer. The shielded control cable manufacturer tells you that this common conductive layer is the shielding layer of the cable, which is generally composed of braided strands of copper (or other metals, such as aluminum), non-woven spiral windings of copper tape, or conductive polymer layers.
The shielded control cable manufacturer tells you that signal or power wires can be wrapped inside the shielding layer to prevent electromagnetic noise interference in two ways.
The shielded control cable manufacturer tells you that on the one hand, it can simply serve as an isolation layer to reflect noise energy; on the other hand, it can absorb noise and conduct it to a large extent, and become a return path for noise signals. And in either case, electromagnetic noise will not be directly transmitted to the line conductor. The shielded control cable manufacturer tells you that although sometimes noise energy may still pass through the shielding layer, it is usually attenuated to a large extent and it is difficult to cause interference. Therefore, whether the cable itself is the source of interference or the subject of interference, the use of shielding for it will be very effective.
