What is the role of Stainless Steel Braided Sleeve on wires and cables?

Wires and cables are mainly composed of three basic structural components: a conductive core, an insulating layer, and a protective sheath. There is no strict boundary between wires and cables, but in a broad sense, the structure of cables is more complicated, and there are complicated sheaths in life, while the structure of wires is very simple, some have conductors and insulation layers, and some only have stainless steel braided sleeves. Apply a waxed light coat or cover with a lightweight soft coat.

The conductive cores of wires and cables are mainly used to transmit current. In order to reduce power consumption and current, the conductive cores are generally made of highly conductive copper and aluminum. The function of the insulating layer is to control the amount of current leakage along the axial direction. Therefore, the insulation layer is required to have good insulation properties. Temperature resistance can be compared with impact toughness. The protective covering outside the insulated cable core is called a cable sheath. The important function of the protective layer is to protect the insulation layer, and its key properties are waterproof, oil-resistant, and anti-corrosion. Anti-aging, flame retardant, and equipment protection, it also has the functions of preventing electric shock, anti-magnetic resistance, etc. From the perspective of wire and cable sheath, it is one of many types of sheaths or outer sheaths for wires and cables. However, according to wire and cable The materials used in the braided network management layer and the different positions of the braided layer in the wire and cable system, the functions of the braided layer are obviously different.
1. The role of chemical fiber Stainless Steel braided sleeve: For wires, the chemical fiber braided layer is a form of lightweight protective layer. Its main function is to protect the insulation layer from or less exposure to various types of light, heat, and moisture. Corrosion from ultra-low temperatures, strong acid and alkali vapors, and damage from external mechanical effects ensures the operation of the wires. But for cables, the chemical fiber braid is often in the middle of the sheath, thereby improving the tear resistance of the sheath. For example, thickened cable sheaths add pure cotton yarn, hemp and other chemicals in the middle of the eraser or plastic sheath. Fiber braiding layer to increase the strength of the sheath.
2. The function of metal Stainless Steel Braided Sleeve: The metal braid mainly includes two types: copper wire braid and stainless steel wire (fine iron wire) braid:
(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 on the surface potential of cables. It restrains cables and eliminates induced currents, such as the overall shielding of high-voltage cables.
(3) Guaranteed shielding effect. Braiding copper wire outside the core insulation layer and making good contact with the ground core or used as a grounding wire can promptly reflect the current leakage situation, such as shielded mining cables.
3. The important function of Stainless Steel Braided Sleeve is
(1) Maintenance function of mechanical equipment. Such as ship wire and cable CF31 type.
(2) Bear vertical breaking force, such as WC-GC and WCT magnetic cables for deep sea geological exploration.
(3) The electromagnetic field is shielded.
