The role of braiding in electric wire and cable

Braiding is one of many kinds of sheaths or outer sheaths of wires and cables. However, the role of the braiding layer is obviously different according to the materials used in the wire and cable braiding layer and the different places of it in the wire and cable structure.  

The role of fiber braided layer 

For electric wires, the fiber braided layer is a form of its light protective layer. Its main role is to protect the insulation from all kinds of light, heat, moisture, low temperature, acid and alkali gases, etc., and external machinery. Force damage to ensure the safe operation of the wire. For cables, the fiber braided layer is often in the middle of the sheath to increase the tear resistance of the sheath. For example, a reinforced sheath is made of a rubber or plastic sheath. Cotton yarn, hemp and other fiber braided layers are added in the middle to improve the strength of the sheath.

3.Shielding function of security protection.  Braided copper wire outside the main core insulation and good contact with the ground core or used as ground wire, can timely respond to the leakage situation, such as shielded mining cable.

3. Magnetic shielding.
