(1) Lead wire is the most essential and indispensable main component of the product to carry current or electromagnetic wave information transmission function. The main material: Wire is the abbreviation of conductive wire core, with copper, aluminum, copper clad steel, copper clad aluminum and other conductive properties of non-ferrous metals made of optical fiber as a guide wire. Bare copper wire, tin wire; single branch, stranded; tin wire after stranded.
(2) Insulation layer is covered in the periphery of the wire around the electrical insulation member. That is to ensure the transmission of current or electromagnetic waves, light waves only along the wire without flowing outward, the conductor has a potential (that is, the potential difference formed between the surrounding objects, that is, the voltage) can be isolated, it is necessary to ensure that the normal transmission wire Function, but also to ensure the safety of objects and personal objects. Wires and insulation are the two basic components that must be available to make a cable product (except for bare wires). Main Material: PVC, PE, XLPE, PP, Fluoroplastic F, rubber, paper, mica tape
(3) Shielding is a component that isolates the electromagnetic field in the cable product from the external electromagnetic field. The cable product also needs to be isolated from each other by different pairs (or groups) of cables inside. It can be said that the shield is a "electromagnetic isolation screen." High-voltage cable conductor shielding and insulation shielding is to homogenize the distribution of electric field. The main material: bare copper wire, copper clad steel wire, tinned copper wire
(4) sheath When the wire and cable products installed in a variety of different environments, must have the product as a whole, especially for the protective layer of insulation, which is the sheath. Because of the requirements of the insulation material has a good variety of electrical insulation properties, you must request a very high purity of the material, the content of impurities is minimal; often can not take into account the protection of the outside world, so for the outside world (that is, installation, use and use ) The resistance or resistance of various types of mechanical forces, the resistance to the atmosphere, chemicals or oils, the prevention of biological damage, and the reduction of fire hazards must all be covered by the various sheathing structures. The main materials: PVC, PE, rubber. Lead, aluminum, steel
(5) filling structure Many wire and cable products are multi-core, these insulated wire or wire into a cable (or grouped into cable several times), one is not round the whole shape, and second, there is a very insulated wire core Therefore, it is necessary to add a filling structure when the cable is filled. The filling structure is to make the outer diameter of the cable relatively round so as to facilitate the wrapping and sheathing. The main material: PP rope
(6) Tensile components. The typical structure is ACSR, fiber optic cable cables. In short, in recent years developed a special small, soft, while requiring multiple bends, twisted use of products, the tensile element plays a major role. The main material: wire
