Do you understand the role of Heat Shrinkable Braided Sleeve on wires and cables?

Wires and cables are mainly composed of three basic structural components: conductive cores, cable sheaths, and wire sheaths. Wires and cables are mainly composed of three basic structural components: conductive cores, cable sheaths, and wire sheaths. 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 are conductors and sheaths, and some only have Heat Shrinkable Braided Sleeve. The casing is lightly coated with wax or covered with a lightweight soft sheath.

The conductive core of wires and cables is mainly used to transmit current. In order to reduce power consumption and current, the conductive core is generally made of highly conductive copper and aluminum. The function of the cable sheath is to control the amount of current leakage along the axial direction to ensure Commercial insurance is used, so the cable sheath is required to have good insulation properties, temperature resistance and impact toughness. The protective covering outside the insulated cable core is called the cable sheath. The important role of the sheath is To protect the cable sheath, its key features are waterproof, oil-resistant, anti-corrosion, anti-sun aging, flame retardant, and equipment maintenance. It also has the functions of preventing electric shock, anti-magnetic dry resistance, etc. From the perspective of wire and cable sheath, thermal Heat Shrinkable Braided Sleeve is one of many types of sheaths or outer sheaths for wires and cables. However, depending on the materials used in the Heat Shrinkable Braided Sleeve layer of wires and cables and the braided layer, the role of the braided layer is obvious in different positions in the wire and cable system. are different.
1. Function of Heat Shrinkable Braided Sleeve layer: For wires, fiber braided layer is a form of light protective layer. Its main function is to protect the insulation layer from or be less exposed to various light and heat, moisture, ultra-low temperature, strong acid and alkali vapor and other corrosion and external mechanical damage, ensuring the operation of the wire, but for cables, the chemical fiber braided layer is often in the middle of the sheath, thereby improving the tear strength of the sheath, such as The thickened cable sheath is to add a braided layer of pure cotton yarn, hemp and other chemical fibers between the eraser or plastic sheath to increase the strength of the sheath.
2. The function of metal heat shrinkable braided casing: Metal braided layers mainly 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 Solve the shielding effect of the surface potential of wires and cables. It restrains the cables and handles the induced current, such as the overall shielding of high-voltage cables.
③ To ensure the shielding effect, the copper wire is braided outside the core insulation layer and is in good contact with the ground core or used as a grounding wire, which can respond to the current leakage situation in time, such as shielded mining cables.
(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.
