What material is the shielding layer of the network cable?

　　The shielding layer of the network cable is made of a variety of materials, including the following:

　　First, aluminum foil shielding

　　Aluminum foil shielding is a common network cable shielding material. It uses a thin layer of aluminum foil to wrap the outer layer of the network cable, the main function is to isolate electromagnetic waves and avoid the interference of the wire from external electromagnetic fields. Aluminum foil shielding not only improves the Reliability of signal tranSMission, but also enhances the protection and durability of the network cable. Due to its relatively low cost, aluminum foil shielding has a wide range of applications in the low-end market.

　　Second, woven mesh shielding

　　Braided mesh shielding uses a fine and uniform braided mesh material as a shielding layer, which has high conductivity and shielding efficiency. This material can effectively isolate electromagnetic waves, and at the same time, compared with aluminum foil shielding, braided mesh shielding is more flexible, bending resistance and durability. In the high-end market, braided mesh shielding (such as tinned copper wire braiding) has become a mainstream shielded mesh material.

　　Third, copper foil shielding

　　Copper foil shielding is also a shielding material for the surface of the network cable. It uses a thin layer of copper foil to wrap the outer layer of the network cable, which can also isolate electromagnetic waves and avoid the interference of the wire from external electromagnetic fields. The shielding effect of copper foil shielding is usually better than that of aluminum foil shielding, but the cost is also relatively high.

　　Four, double shielding

　　The double-layer shielding structure combines the Advantages of aluminum foil or copper foil shielding and braided mesh shielding to form a strong shielding effect. This structure can effectively shield electromagnetic interference and improve the transmission speed and Stability of the network cable. In the high-end market, the double-layer shielding network cable has become the first choice for users who pursue strict network performance.

　　Other materials

　　In addition to the above-mentioned common shielding materials, there are also some special shielding materials, such as gold-plated, silver-plated, etc., but these materials are relatively rarely used in the shielding layer of network cables.

　　In summary, the shielding layer of the network cable is made of a variety of materials, each of which has its own unique characteristics and applications. When selecting a network cable, the appropriate shielding material should be selected according to the specific application environment and needs.
