A stable and reliable network cable product depends not only on its high-performance network transmission capabilities but also on the materials and manufacturing processes used. Let's explore the mysteries of network cable materials and manufacturing processes. **I. Network Cable Materials** 1. **Conductor Materials**: The core component of a network cable is the conductor, which is usually a copper wire. Pure copper or tin-coated copper wires are widely used due to their excellent electrical conductivity. High-purity copper wires can ensure lower resistance and higher signal transmission efficiency. 2. **Insulating Materials**: Each wire in the network cable needs to be isolated with insulating materials. Common insulating materials include PVC (polyvinyl chloride) and cross-linked polyethylene. These materials have excellent insulating and aging resistance properties, ensuring that signals do not attenuate due to interference between wires during transmission. 3. **Protective Layer Materials**: To prevent the cable from damage caused by external forces and resulting in signal attenuation, a high-strength and wear-resistant material is used for the outer layer, such as flame-retardant PVC or aluminum foil shielding layers. **II. Manufacturing Processes** 1. **Conductor Manufacturing**: Copper wires are processed through drawing and annealing processes to form fine copper wires of the desired diameter. This step aims to reduce resistance and improve the flexibility of the wire. 2. **Insulation Processing**: Clean and dried copper wires are coated with insulating materials, which are uniformly wrapped around the copper wires through special extrusion machines. This step ensures isolation between each wire. 3. **Braiding and Cabling**: Multiple insulated wires are braided or twisted together to form the basic structure of the cable. This step increases the tensile strength and resistance to bending of the cable. 4. **Protective Coating Processing**: To make the cable more durable and moisture-resistant, a protective outer sheath or shielding layer is added, usually using high-strength plastic or metal braid mesh. 5. **Quality Testing**: After manufacturing, each network cable must undergo rigorous quality testing, including visual inspection, conductivity testing, etc., to ensure product
