A brief analysis of the important role of Pattern Braided Sleeve on wires and cables

Wires and cables are mainly composed of three main structural components: conductive core, insulating layer, and protective sheath. Electric wires and cables are mainly composed of three main structural components: conductive core, insulating layer, and protective sheath. Electric wires and There are no strict boundaries for the difference between cables, but in a broad sense, the cable structure is more complicated. It has a complicated protective sheath, while the wire structure is very simple. Some have wires and insulation layers, and some only have Pattern Braided Sleeve. Apply a waxed light coat or cover with a lightweight soft coat.

The conductive cores of wires and cables are used to transmit alternating current. In order to reduce electromagnetic energy loss and current, the conductive cores are generally made of copper and aluminum with high conductivity. The function of the insulating layer is to prevent the current from leaking along the axial direction and ensure The use of commercial insurance requires that the insulation layer must have excellent insulation properties, temperature resistance and impact toughness. The protective soil layer outside the insulated cable core or cable core is called the cable sheath. The important role of the sheath is It is to protect the insulation layer. Its main functions are water resistance, oil resistance, corrosion resistance, anti-sun aging, flame retardancy, and mechanical equipment protection. It also has the functions of preventing electric shock, anti-magnetic dry resistance, etc. from the wire and cable sheath. From a perspective, braided sleeves are one of many types of sheaths or outer sheaths for wires and cables. However, depending on the materials used by wire and cable Pattern Braided Sleeve manufacturers and the different positions of the braided layer in the wire and cable structure, the role of the braided layer It's obviously different.

1. The role of the fiber braided network layer: For wires, the fiber braided layer is a form of light protection layer. Its main function is to protect the insulation layer from or be less exposed to various types of light. Corrosion from heat, moisture, low temperature, strong acid and alkali exhaust gas, etc. and damage from external mechanical forces ensure the operation of the wire. For cables, the fiber braid is usually in the middle of the sheath, thereby improving the durability of the sheath. Wear strength, such as thickened cable sheaths, add cotton, hemp and other fiber braiding layers inside the eraser or plastic sheath to increase the sheath's strength.

2. Metal Pattern Braided Sleeve layers include copper wire braided layer and stainless steel wire braided layer:

① Anti-interference signal shielding effect, such as tinned copper wire braided blue cable, copper wire braided frequency conversion cable, etc.

② It has a shielding effect to solve the potential difference on the surface of wires and cables. It restrains the cables and solves the induced current, such as the total shielding of high-voltage cables.

③ To protect the shielding function, braid copper wire outside the main core insulation layer and have a good connection with the ground core or be used as a grounding wire, which can directly reflect the current leakage situation, such as shielded mining cables.
