The important role of Stainless Steel Braided Sleeve on wires and cables

Wire and cable are mainly composed of three main structural components: conductive core, insulating layer and sheath layer. Wire and cable are mainly composed of three main structural components: conductive core, insulating layer and sheath layer. Wire and There is no strict boundary for the difference between cables, but in a broad sense, the cable structure is more complicated, it has a complicated sheathing layer, and the wire structure is very simple, some have wires and insulation layers, and some have only stainless steel braiding The casing is waxed light sheath or covered with a light soft sheath.

In order to reduce electromagnetic energy loss and current, the conductive wire core is generally made of copper and aluminum with high conductivity. The function of the insulating layer is to prevent the leakage of current along the axial direction and ensure the application of commercial insurance. Therefore, the insulating layer must have excellent insulation Characteristics, temperature resistance and impact toughness, the protective soil layer outside the insulated cable core or the cable core is called the cable sheath. The key function of the sheath is to protect the insulation layer. Its main function is waterproof, Oil, anti-corrosion, anti-aging, flame retardant, and mechanical equipment protection, also has the functions of anti-electric shock, anti-magnetic dry resistance, etc. From the perspective of wire and cable sheath, braided network administrator is a variety of wire and cable sheaths Or one of the outer sheaths, however, according to the material used in the wire and cable braided network management layer and the different positions of the braided layer in the wire and cable structure, the function of the braided layer is obviously different.
1. The role of the Silicone Glass Fiber Tube network management layer: for electric wires, the Silicone Glass Fiber Tube layer is a form of light protective layer, and its main function is to protect the insulating layer from being exposed to or less exposed to various light, Corrosion of heat, tide, ultra-low temperature, strong acid and strong alkali exhaust gas, etc. and damage of external mechanical equipment to ensure the operation of the wire, and for cables, the chemical Silicone Glass Fiber Tube is usually in the middle of the sheath, thereby improving the resistance of the sheath Wear strength, such as thickened sheath is to add yarn, hemp and other Silicone Glass Fiber Tube inside the rubber or plastic sheath to increase the strength of the sheath.
2. There are two types of braided layers of metal materials: copper wire braided layer and stainless steel wire braided layer:
1. The shielding effect of anti-interference signal, such as tinned copper wire braided blue cable, copper wire braided frequency conversion cable, etc.
2. Solve the shielding effect of the potential difference on the surface of the wire and cable. It can restrain the cable and solve the induced current, such as the total shielding of the high-voltage cable.
3. To protect the shielding effect, weave copper wires outside the insulation layer of the main core and make a good connection with the ground core or use it as a grounding wire, which can immediately reflect the leakage status, such as shielded mine cables.
(1) Mechanical equipment maintenance function, such as ship wire and cable CF31 type.
(2) Undertake vertical tearing force, such as WC-GC and WCT type magnetic measuring cables for deep sea geological exploration.
(3) The electromagnetic field is shielded.
