In addition to the strict selection of materials for the power cord, the influence of the manufacturing process on the power cord must be strengthened. At present, what are the manufacturing processes of power cords in my country?

　　 1. Wire drawing

　　 The core component of the power cord is the metal wire, so the metal wire must be processed by the drawing process. In a normal temperature environment, the metal wire is placed on the wire drawing machine and passed through one or several die holes of the drawing die to make the cross section smaller and increase the strength. Wire drawing is the first process for power cord manufacturers. Only after the metal wire is pulled out of specifications, can the next process production be carried out.

　　 2. Monofilament annealing

　　In order to strengthen the toughness and tensile strength of the metal wire, it must go through the monofilament annealing process. The metal wire is heated to a certain degree, and then the various properties of the metal wire are strengthened by crystallization to meet the requirements of consumers for conductors. At the same time, the monofilament annealing process can also prevent the oxidation of the metal wire, and the Rolex GMT-Master Vintage replica extends its normal working life.

　　 3. Conductor stranding

　　 In addition to a certain degree of tensile strength, the power cord also needs a certain degree of flexibility to meet the installation and arrangement requirements of the power cord. In order to have better flexibility, conductor stranding processes are generally carried out. This process is generally made by twisting a single filament, and the twisting method is divided into regular twisting and irregular twisting.

　　4. Power cord internal protection technology

　　In order to prevent the insulated core from being affected by the installation, the insulation layer needs to be properly treated. This requires the inner sheath to be divided into extruded inner sheath (isolation sleeve) and wrapped inner sheath (cushion).

　　Of course, in addition to these four main processes, there are other ways to make the power cord, but this article will tell you about the four power cord production processes, so that everyone can know the production process of the power cord.
