Abstract

The invention discloses an anti-electromagnetic interference network cable. The cable is formed by intertwisted cable cores. An outer layer wraps on the outer surface of each cable core, and two cable cores are intertwisted together and coated by an inner shielding layer. The cable also comprises an insulating layer, and four groups of cable cores are arranged inside the insulating layer, wherein each group includes two of the intertwisted cables coated by the inner shielding layer. The cable employs a multi-layer split shielding structure to improve the anti-electromagnetic interference capability effectively. Besides, the inner shielding layer is produced from composite material. A composite formula of metal silver, iron, tin, lithium, titanium oxide, silicon carbide and graphite can improve the capability of the material to form symmetric currents, so that the magnetic field inside the cable is better eliminated, the anti-electromagnetic interference capability is improved, and the noise is reduced. A separating rod is made of insulating composite material with good acid and alkali resistant properties of phenolic resins and good waterproof and moisture-proof properties of stearic acid amide, so that the cable is improved in environmental resistance and extended in service life.

Description

technical field [0001] The invention relates to a network cable, in particular to a network cable with good anti-electromagnetic interference effect. Background technique [0002] NetworkCable is a medium that transmits information from one network device (such as a computer) to another network device, and is the basic component of the network. In our commonly used local area network, there are also many types of network cables used. Under normal circumstances, a typical LAN generally does not use many different types of network cables to connect network devices. In a large network or a wide area network, different types of network cables are used to connect different types of networks together. Among the many types of network cables, which one to use depends on the topology of the network, network structure standards and transmission speed. [0003] UTP is the most frequently used network cable in the local area network. This kind of network cable has eight signal wires...
