SMB Cable manufacturers will show you: What are the protective functions of the cable shielding layer


SMB Cable manufacturers tell you that cables are generally composed of conductors, insulation layers, outer tapes and outer sheaths. SMB Cable manufacturers tell you that the function of the insulation layer is to prevent leakage accidents and ensure the safety of electricity; the function of the outer sheath layer is to reduce the damage and erosion of the wire and cable caused by the external environment; and the inner sheath layer is mainly to protect the conductor.

However, inside the cable, there will be a special protective layer, which we generally call a shielding layer. The main reasons for the existence of the shielding layer are:
1. The SMB Cable manufacturer tells you that the meaning of shielding is to make the electrons in the electric field terminate on the surface of the shield and be introduced to the ground, so as to achieve the function of separating the electric field. The shielding layer protects the inner cable core of the shield from the interference of the strong external electric field. It is of great significance to control cables, communication cables, computer and instrument cables.
2. We all know that a magnetic field is generated when the current flows. The larger the current passing through, the stronger the magnetic field. SMB Cable manufacturers tell you that in order to prevent the generated magnetic field from affecting the surrounding equipment or equipment, a shielding layer is added to ensure the magnetic field. Will not affect the operation of external equipment, reducing unnecessary troubles.
3. The SMB Cable manufacturer tells you that the shielding layer can also play a role in leakage protection. The manufacturer of SMB Cable tells you that if the cable is damaged during use, causing leakage, the shielding layer is grounded so that the current can be led to the ground wire, which has a certain protective effect. At the same time, it also protects the cable conductor.
What's more special is that the current flowing through the cable during use is generally not very large, and the shielding layer can also reduce external signal interference. The main function of the shielding layer of the cable is to shield the cable from external influences. The SMB Cable manufacturer tells you that because the cable transmits signals, which are affected by the outside world and fluctuate greatly, a shielding layer is added to protect the inside of the cable. And this is where the greater role of the cable shielding layer lies.
