(3) Material and Style
Yvv Cyy-F Nyy 4-core 35mm² copper ground PVC low-voltage cable (4X35) fully considers performance, safety and use needs in material selection and style design.
In terms of materials, the conductor is made of high-purity electrolytic copper, which has extremely high purity and excellent conductivity. High-purity copper can reduce the resistance during current transmission, thereby reducing energy loss and improving power transmission efficiency. At the same time, electrolytic copper has good ductility and plasticity, which is convenient for processing into conductors of various specifications, and is not easy to break during bending, stretching, etc., ensuring the mechanical properties of the cable. In addition, copper has good corrosion resistance, which can resist the erosion of the external environment to a certain extent and prolong the service life of the cable.
The insulation layer and sheath of the cable are made of high-quality polyvinyl chloride (PVC) material. PVC is a commonly used polymer material with good insulation performance, which can effectively isolate current, prevent electric leakage, and ensure the safety of power transmission. At the same time, PVC material has good corrosion resistance, can resist the erosion of acids, alkalis, salts and other chemical substances, and adapt to different environmental conditions. Its weather resistance is also excellent. Under high temperature, low temperature, humidity and other climatic conditions, the performance changes little, and can maintain stable insulation and protection effects. In addition, PVC material also has certain mechanical strength, can bear a certain external impact and friction, and protect the internal conductor from damage. Moreover, the PVC material used in the cable has flame-retardant properties, meets relevant fire safety standards, and can inhibit the combustion and spread of flames in case of fire, reducing the loss caused by fire.
In terms of style design, the cable adopts a circular structure, which makes the cable more convenient in the laying process and can adapt to different installation methods, such as buried, piped, overhead, etc. The circular cross-section is evenly distributed and the force is balanced, which can reduce internal stress during bending and avoid damage to the conductor and insulation layer. At the same time, the surface of the cable is smooth, which is convenient for handling and installation, and reduces the resistance during installation.
In addition, the color identification of the cable is clear. Different cores are distinguished by different colors. For example, phase lines usually use yellow, green and red, and ground lines use yellow-green two-color. This design is convenient for construction personnel to quickly identify during installation and maintenance, improves work efficiency, and reduces safety accidents caused by wrong wiring.
(4) Production Process
The production process of Yvv Cyy-F Nyy 4-core 35mm² copper ground PVC low-voltage cable (4X35) adopts a series of advanced process technologies to ensure the quality and performance of the product.
The first is the manufacturing process of the conductor. High-purity electrolytic copper is used as raw material, and copper rods are made through smelting, ingot casting and other processes. Then, the copper rod is drawn into
Copper Wire of the required diameter through the wire drawing process. During the wire drawing process, the drawing speed and tension need to be controlled to ensure the dimensional accuracy and mechanical properties of the copper wire. The drawn copper wire is annealed to eliminate internal stress and improve the flexibility and conductivity of the copper wire. Finally, multiple copper wires are stranded into conductors through bunching or compound stranding processes. During the stranding process, the structure of the conductor must be tight and round to reduce the skin effect during current transmission and improve the conductivity efficiency.
Next is the extrusion process of the insulation layer. The
PVC Insulation layer is extruded outside the conductor, and this process is carried out by a special extruder. First, the PVC raw materials are mixed and plasticized, and then the molten PVC material is evenly coated on the surface of the conductor through an extrusion die to form an insulation layer. During the extrusion process, it is necessary to accurately control the extrusion temperature, speed and pressure to ensure that the insulation layer has uniform thickness, smooth surface, and good adhesion with the conductor. The thickness of the insulation layer must meet relevant standards to ensure its insulation performance.
Then there is the cabling process. The 4
Insulated Cores (3 phase lines and 1 ground line) are stranded according to a certain pitch to form a cable core. A cabling machine is needed in the cabling process, and at the same time, some filling materials may be filled in the middle of the cable core to ensure the roundness and stability of the cable core. The filling material usually adopts polypropylene rope, etc., which has good flexibility and corrosion resistance.
After cabling, the extrusion process of the sheath is carried out. Similar to the extrusion of the insulation layer, a PVC sheath is extruded outside the cable core. The function of the sheath is to protect the cable core from the influence of the external environment, such as mechanical damage, chemical corrosion, moisture intrusion, etc. The sheath extrusion process also needs to strictly control various process parameters to ensure that the sheath has uniform thickness, smooth surface, and close combination with the cable core. The color of the sheath is usually black, which has good weather resistance.
In the production process, a series of quality inspection processes are also required. For example, the diameter and DC resistance of the conductor are tested to ensure that they meet the standards; the thickness, insulation resistance, voltage resistance performance of the insulation layer and sheath are tested to ensure their insulation and protection performance; the appearance and structural size of the cabled cable are inspected to ensure the quality of the product. In addition, some key processes also adopt automatic control and online monitoring technology to monitor various parameters in the production process in real time, find and solve problems in time, and improve production efficiency and the stability of product quality.
II. From the Perspective of General Product Information
(1) Packaging
The packaging design of Yvv Cyy-F Nyy 4-core 35mm² copper ground PVC low-voltage cable (4X35) fully considers the protection, transportation and storage needs of the product, and adopts a scientific and reasonable packaging method.
Cables are usually packaged with cable reels, and there are two types of cable reels: wooden cable reels and steel cable reels. For cables with longer lengths, steel cable reels are generally used, because steel cable reels have high strength and bearing capacity, can bear large cable weights, and are more stable and reliable during transportation and hoisting. Wooden cable reels are suitable for cables with shorter lengths, which are lighter in weight and relatively low in cost.
When the cable is wound on the cable reel, it needs to be carried out according to a certain tension and order to ensure that the cable is arranged neatly and tightly, and avoid loosening, twisting or mutual friction during transportation, which may cause damage. After winding, the two ends of the cable will be sealed, usually with plastic 封头 or insulation tape, to prevent moisture, dust and other impurities from entering the inside of the cable and affecting the performance of the cable.
The outside of the cable reel will be wrapped with a moisture-proof and dust-proof packaging material, such as plastic film or linen. The plastic film has good moisture-proof performance and can prevent the cable from getting damp during storage and transportation; the linen has certain wear resistance and air permeability, which can not only protect the cable reel from collision and friction, but also prevent the cable from producing peculiar smell or getting damp due to long-term sealing.
In addition, the cable reel will be provided with clear marks, including product name, model specification, length, weight, manufacturer, production date, execution standard and other information. These marks are convenient for users to identify and accept products, and also conducive to product traceability and management. Lifting holes are also installed on the side of the cable reel to facilitate the hoisting and transportation of the cable reel.
For export products, the packaging also needs to meet international transportation standards and the requirements of relevant countries, such as using fumigated wooden cable reels to prevent the spread of diseases and pests. At the same time, the strength and stability of the packaging also need to be further improved to adapt to long-distance transportation and multiple loading and unloading needs.

For road transportation, special freight vehicles, such as flatbed trucks and vans, are needed. The carrying capacity and size of the vehicles need to match the weight and size of the cable reel. When loading the cable reel, ensure that the cable reel is placed stably and firmly to avoid tilting, rolling or collision during transportation. Steel wire ropes, iron chains, etc. can be used to fix the cable reel on the vehicle, and the fixed points should be selected in the solid parts of the cable reel to ensure reliable fixation.
For long-distance transportation or transportation of large quantities of goods, railway transportation and water transportation are more economical choices. Railway transportation has the advantages of large transportation volume, good stability and little affected by weather; water transportation is suitable for coastal areas or areas with inland waterway shipping conditions, and the transportation cost is low. During railway transportation and water transportation, the cable reels need to be stacked reasonably to avoid mutual extrusion and collision. At the same time, moisture-proof, sun-proof, dust-proof and other protective measures should be taken to ensure that the cable is not affected by the external environment.
Air transportation is usually applicable to emergency situations or transportation of small batches of goods. It has a fast transportation speed but high cost. In air transportation, it is necessary to abide by the relevant regulations of the airline, properly package and fix the cable reel to ensure transportation safety.
