What are the current manufacturing processes of power cords?

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

1. Metal 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 the normal temperature environment, the metal wire is placed on the wire drawing machine, and passes through one or several die holes of the drawing die, so that the cross section becomes smaller and the strength is increased. Drawing is the first process for power cord manufacturers to do. Only after the wire is pulled out of specification can the next process be made.

2. Monofilament annealing

In order to enhance the toughness, tensile strength and other properties of the metal wire, it is necessary to go through a single wire annealing process. The metal wire is heated to a certain extent, and then the various properties of the metal wire are strengthened in a crystalline manner to meet the consumer's requirements 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 prolongs its normal working life.

3. Conductor stranding

In addition to a certain 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 make it have better soft performance, the conductor stranding process is generally carried out. This process is generally made by twisting a single filament, and the twisting method is divided into regular twisting and non-regular twisting.

4. Inner protection process of power line

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

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