July 22, 2021. 1． New energy cable manufacturer Power line of copper and aluminum monofilament drawing
The copper and aluminum rods commonly used for power lines of electronic wire manufacturers shall pass through one or several drawing die holes with a wire drawing machine at room temperature, so as to reduce the section, increase the length and improve the strength. Wire drawing is the first process of each wire and cable company, and the primary process parameter of wire drawing is die matching technology.
2． New energy cable Manufacturer's single wire annealing
When the copper and aluminum monowires are heated to a certain temperature, the toughness of the monowires is improved and the strength of the monowires is reduced by recrystallization to meet the requirements of wires and cables for conductor cores. The key of annealing process is to eliminate the oxidation of copper wire
3. Stranding of power line conductor of new energy cable manufacturer
In order to improve the flexibility of the power line of the electronic wire manufacturer and facilitate the laying device, the conductive wire core is twisted by multiple single wires. According to the stranding mode of conductor core, it can be divided into regular stranding and irregular stranding. Irregular stranding can also be divided into bundle stranding, concentric stranding, and extraordinary stranding. In order to reduce the occupied area of the conductor and the geometric size of the power line of the electronic wire manufacturer, the compact pressing method is also used for the stranded conductor, so that the popular circle can be changed into semicircle, sector, tile and compact circle. This conductor is mainly used on the power line of the electronic wire manufacturer.
4. Power cord insulation extrusion of new energy cable manufacturer
The power line of plastic electronic wire manufacturer mainly adopts extruded solid insulation layer, and the primary technical requirements for plastic insulation extrusion are as follows:
5. Power line of new energy cable manufacturer
For the power cord of multi-core electronic wire manufacturers, in order to guarantee the molding degree and reduce the appearance of the power cord of electronic wire manufacturers, it is generally required to twist it into a round shape. The mechanism of stranding is similar to that of conductor stranding, because the stranding pitch diameter is large, most of them adopt the method of no untwisting. Technical requirements for cabling: First, avoid twisting and bending of cables caused by turning over of profiled insulated wire cores; The second is to prevent the insulation layer from being scratched.
6. Power cord inner sheath of new energy cable manufacturer
In order to maintain the insulated core from being damaged by the armor, it is necessary to properly maintain the insulation layer. The inner protective layer is divided into extruded inner protective layer (isolation sleeve) and wrapped inner protective layer (cushion). The wrapping cushion replaces the binding belt and the cabling process is carried out simultaneously.
7. Power wire armouring of new energy cable manufacturer
The power line laid in the underground electronic wire manufacturer can accept the necessary positive pressure effect in the task, and the internal steel belt armored structure can be selected. The power line of the electronic wire manufacturer is laid in places with both positive pressure effect and tensile effect (such as water, vertical shaft or soil with large drop), and the selector shall be of inner steel wire armored construction.
8. Outer sheath of power line of new energy cable manufacturer
The outer sheath is a part of the structure that maintains the insulation layer of the power line of the electronic wire manufacturer to avoid corrosion of the elements of the situation. The primary effect of the outer sheath is to improve the mechanical strength, chemical erosion resistance, moisture resistance, water immersion resistance, and prevent the power cord from burning of the electronic cord manufacturer. According to the different requirements for the power line of the electronic wire manufacturer, the plastic sheath shall be directly extruded by the extruder.
