Cable manufacturers take you to explore the production process of wires and cables
Wire and cable are measured in length as the basic unit of measurement. All wire and cable products are made by adding insulation, shielding, cable formation, and protective layers layer by layer on the periphery of the conductor, starting from the processing of the conductor. The more complex the product structure is, the more layers are stacked.Cable manufacturers take you into the workshop of wire and cable production, revealing the process flow of wire and cable production.
1. Wire drawing is a commonly used copper and aluminum rod material for wires and cables. At room temperature, a wire drawing machine is used to reduce the cross-section, increase the length, and enhance the strength by passing through one or several holes of the drawing mold. Wire drawing is the first process of various wire and cable manufacturers.
2. Twisting of conductors: In order to improve the flexibility of wires and cables for easy installation, the conductive wire core is made by twisting multiple single wires. In order to reduce the occupied area of wires and the geometric size of cables, a compact form is adopted while twisting the conductors, transforming ordinary circles into semicircles, fan-shaped, and compact circles. This type of conductor is mainly used in power cables.
3. Insulation extrusion, plastic wires and cables mainly use extruded solid insulation layer, and the main technical requirements for plastic insulation extrusion. The surface of the extruded insulation layer must be smooth and free from poor quality issues such as surface roughness, burning, and impurities. For multi-core cables, in order to ensure their formability and reduce their shape, they generally need to be twisted into a circular shape. One is to prevent the twisting and bending of cables caused by the flipping of irregular insulated wire cores; The second is to prevent the insulation layer from being scratched.
