Small-load Scenarios
Household incoming lines: Daily household electrical equipment such as lamps, TVs, and refrigerators have relatively small total power. Cables with small cross-sectional specifications such as 4×35mm² and 4×50mm² are sufficient to meet household electricity needs, and can safely and stably introduce external power into the household internal power distribution system to ensure the normal operation of various household appliances.
Small shop power distribution: Small shops such as convenience stores and small restaurants have electrical equipment mainly including lighting, cash registers, and small refrigerators, with low power load. Small cross-sectional cables can be used as power distribution lines for shops to provide power support for these equipment. Moreover, they are easy to install and can adapt to the limited space layout of shops.
Medium-load Scenarios
Total power distribution of multi-storey buildings: Multi-storey residential buildings, office buildings and other multi-storey buildings need to introduce power from the outside and then distribute it to each floor and room. Cables with medium cross-sectional specifications such as 4×70mm² to 4×185mm² can be used as total power distribution lines, with sufficient current-carrying capacity to meet the power needs of the entire building and ensure the normal operation of electrical equipment on each floor.
Power supply for small and medium-sized industrial equipment: Some small and medium-sized industrial equipment such as machine tools and injection molding machines need certain power support during operation. Medium cross-sectional cables can provide stable power for these equipment, ensuring the start-up and continuous operation of the equipment and improving production efficiency.
Medium and High-load Scenarios
Main lines of large factories: Large factories usually have a large number of large production equipment with high power consumption. Cables with large cross-sectional specifications such as 4×240mm² and 4×300mm² can be used as main lines to transmit power from substations or distribution rooms to various areas in the factory, providing sufficient power for various large equipment and ensuring the continuity of production.
Regional distribution trunk lines: In some areas such as residential communities and industrial parks, power needs to be distributed to various sub-areas through distribution trunk lines. Large cross-sectional cables can take on this important task, efficiently transmit power, ensure stable power supply in the area, and meet the electricity needs of many users and enterprises.
Material
Conductor: Aluminum (Al) is used as the conductor. Aluminum has good electrical conductivity and can effectively transmit electricity. Compared with copper, aluminum has a lower price, which reduces the production cost of the cable to a certain extent and makes the cable have a high cost performance. At the same time, aluminum has a low density, so the weight of the cable is relatively light, which is convenient for transportation and installation.
Insulation layer: Cross-linked polyethylene (XLPE) is used as the insulation layer. XLPE has excellent temperature resistance and can maintain a stable insulation effect in a relatively high temperature environment. Even when the cable generates heat during long-term operation, it can effectively prevent current leakage. Moreover, it has a large insulation resistance and stable insulation performance, which can greatly reduce safety risks such as electric leakage and ensure the safe operation of the cable.
Style
Conductor Preparation: First, strictly screen aluminum raw materials to remove impurities. Then, melt the aluminum materials. During the melting process, control the temperature and time to ensure the purity of the aluminum liquid. After that, make the aluminum liquid into aluminum rods through continuous casting process, and then draw the aluminum rods into Aluminum Wires of the required diameter through wire drawing process. Finally, strand multiple Aluminum Wires together to form an aluminum conductor. During the stranding process, ensure the roundness and tightness of the conductor to ensure its electrical conductivity.
Insulation Layer Extrusion: Adopt the extrusion molding process. Heat and melt the XLPE material, then evenly extrude and coat it on the outside of the aluminum conductor through an extruder to form an insulation layer. During the extrusion process, accurately control parameters such as extrusion temperature, speed and pressure to ensure that the insulation layer has a uniform thickness, a smooth surface, and is closely combined with the conductor, avoiding defects such as bubbles and depressions. After extrusion, cool and solidify the insulation layer.
Cabling: Strand four cores covered with insulation layers together in a certain stranding way. During stranding, ensure that the positions of each core are uniform and the tension is consistent to ensure the roundness and structural stability of the cable. During the cabling process, filling materials may be added in the center to make the cable structure more compact.
Sheath Extrusion (if any): According to actual needs, some cables may have a sheath extruded on the outside after cabling. The sheath material usually has certain wear resistance, corrosion resistance and moisture resistance, which can further protect the internal structure of the cable. The extrusion process is similar to that of the insulation layer, and the quality of the sheath must be guaranteed.
Inspection and Testing: After production, conduct a series of strict inspection and testing on the cable. Including appearance inspection to check whether the surface of the cable is damaged or deformed; dimension measurement to detect whether the cross-sectional dimension and insulation layer thickness of the cable meet the standards; electrical performance testing such as insulation resistance testing and withstand voltage testing to ensure that the electrical performance of the cable meets the requirements; mechanical performance testing such as tensile strength and elongation at break to ensure that the cable has sufficient mechanical strength during use. Only cables that pass all tests can leave the factory.
Packaging Materials: Mainly use cable reels as packaging carriers. Cable reels are usually made of wood or metal, with sufficient strength and bearing capacity, which can support the weight of the cable and prevent the cable from being deformed during transportation and storage. On the outside of the cable reel, the cable will be wrapped with a plastic film. The plastic film can play the role of moisture proof and dust proof, avoiding pollution and damage to the cable surface. For some shorter cables, carton packaging may also be used, but buffer materials must be placed inside the carton to prevent the cables from colliding with each other during transportation.
Packaging Method: Neatly wind the cable on the cable reel. During winding, ensure that the cable is arranged closely without distortion or overlap to avoid extrusion and wear of the cable. After winding, wrap the entire cable tightly with a plastic film, then fix the cable on the cable reel with steel strips or ropes to prevent the cable from loosening during transportation. For cables of different specifications, select cable reels of appropriate sizes for packaging to improve the rationality of packaging.
Transportation Methods: Select appropriate transportation methods according to factors such as transportation distance, cable quantity and customer needs. For short-distance transportation, road transportation is generally used. Road transportation has high Flexibility and can directly deliver cables to the customer's designated place, which is suitable for small-batch and urgent orders. For long-distance transportation, railway transportation or long-distance road transportation can be chosen. Railway transportation has a large transportation capacity and good stability, which is suitable for transporting large quantities of cables; long-distance road transportation can cover a wider range of areas.
Transportation Precautions
Loading: When loading cables, use special hoisting equipment to avoid rough handling. The cable reels should be placed stably on the transport vehicle to ensure stable center of gravity and prevent tilting and toppling. Leave a certain gap between multiple cable reels to avoid collision and extrusion between them. At the same time, fix the cable reels on the vehicle with ropes or chains. The fixation must be firm and reliable to prevent displacement during transportation.
Protection: Take protective measures during transportation to prevent the cable from being exposed to direct sunlight, rain and high-temperature exposure. In case of bad weather, cover the cable with a rainproof cloth. In high temperatures in summer, try to choose to transport in the morning and evening to avoid cable aging due to high temperature. In addition, avoid contact between the cable and sharp objects to prevent the sheath from being cut.
Unloading: When unloading cables, also use appropriate equipment and lift and place them gently. It is strictly forbidden to directly push the cable reels off the transport vehicle to avoid damaging the cables and cable reels. After unloading, place the cable reels on a flat and solid ground and fix them to prevent rolling.
