Weaving is one of many kinds of sheaths or outer sheaths of wires and cables. However, according to the materials used in the braiding of the wire and cable and the different parts of the braid in the wire and cable structure, the effect of the braid is obviously different. First, the role of fiber braid For wires, the fiber braid is a form of its lightweight protective layer. Its main function is to protect the insulation from all kinds of light, heat, and tide. Low temperature, acid and alkali gas erosion and external mechanical damage, to ensure the safe operation of the wire. For cables, the fiber braid is often in the middle of the sheath to enhance the tear strength of the sheath. For example, the reinforced sheath is made by adding cotton yarn, hemp, etc. to the middle of the rubber or plastic sheath to increase the strength of the sheath. Cover strength. Second, the role of metal braid The metal braids are mainly copper wire braids and wire (wire) braids. The main role of copper wire weaving is: L- Shielding effect against electromagnetic interference, such as tinned copper wire braided blue cable, copper wire braided control cable, etc. 2. Eliminate the shielding effect of the surface potential of the power cable. It plays the role of restraining power lines and eliminating inductive power, such as the total shielding of high voltage cables. 3. The shielding effect of security protection. In the main core insulation braided copper wire and good contact with the ground or for the use of ground, timely response to leakage conditions, such as shielded mining cable. The main role of wire braiding is: l. Mechanical protection effect. Such as marine power cable CF31 type. 2. Longitudinal pull-off force, such as WC-GC, WCT-type magnetic cable for marine geological exploration. 3. Magnetic shielding.
