Small Cross-Section Cables (4×70mm², 4×95mm²)
Shop Power Distribution: Various shops such as clothing stores, restaurants, and convenience stores have electrical equipment mainly including lighting fixtures, cash registers, air conditioners, and small refrigerators, with relatively low overall power load. Cables of 4×70mm² and 4×95mm² can stably supply power to these equipment, ensuring the power demand for the daily operation of the shops. Moreover, such cables are small in size, making wiring more flexible in the limited space of the shops without occupying excessive space.
Small-Sized Equipment Power Supply: Small-sized equipment such as small machine tools, small water pumps, and small fans usually have low power. Small cross-section cables can meet the power supply requirements for their start-up and operation, ensuring the normal operation of the equipment. At the same time, the installation positions of small-sized equipment may be relatively compact, and small cross-section cables have good Flexibility, which is convenient for wiring and connection around the equipment.
Medium Cross-Section Cables (4×120mm² to 4×185mm²)
Total Power Distribution of Multi-Storey Buildings: Multi-storey residential buildings, multi-storey office buildings, and other multi-storey buildings need to introduce external power and then distribute it to each floor. The total power load of such buildings is moderate. Cables of 4×120mm² to 4×185mm² can undertake the task of total power distribution, efficiently and stably transmitting power to the distribution junction boxes on each floor, and then the junction boxes distribute it to each user or office.
Power Supply for Small and Medium-Sized Industrial Equipment: Some small and medium-sized industrial equipment such as equipment in small and medium-sized production lines and medium-sized compressors need certain power support during operation. Medium cross-section cables can provide sufficient current to meet the power demand of the equipment and ensure the normal progress of production. In addition, the workshop environment where these equipment are located may be relatively complex, and the cables have certain environmental resistance and can adapt to the service conditions of the workshop.
Large Cross-Section Cables (4×240mm², 4×300mm²)
Factory Main Lines: Large factories have many large production equipment such as large machine tools and large furnaces, with extremely high power consumption. Large cross-section cables of 4×240mm² and 4×300mm² can be used as the main lines of the factory to transmit power from the factory's distribution room to each production workshop, providing sufficient and stable power for large equipment and ensuring the continuity of factory production.
Regional Distribution Trunk Lines: In areas such as large residential communities and industrial parks, power needs to be transmitted from substations to each sub-area through distribution trunk lines. These areas have many power users and large total power consumption. Large cross-section cables can efficiently transmit a large amount of power, ensuring stable and reliable power supply in the area and meeting the power demand of residents' lives and enterprise production.
Material
Conductor: Aluminium is used as the conductor. Aluminium has good electrical conductivity and can transmit power efficiently. Compared with Copper Conductors, aluminium has a lower price, which reduces the production cost of the cable and gives it a certain price advantage in the market. At the same time, aluminium has a low density, so the weight of the cable is relatively light, which not only reduces transportation costs but also makes the cable more labor-saving and convenient during installation.
Insulation Layer: Cross-linked polyethylene (XLPE) is used as the insulation layer. XLPE has excellent temperature resistance and can maintain stable insulation performance in a relatively high-temperature environment. Even if the cable heats up during long-term high-current transmission, it can effectively prevent current leakage. In addition, XLPE has good chemical stability and is not easily corroded by chemical substances, which can prolong the service life of the cable. Moreover, it has a large insulation resistance and good insulation effect, which greatly improves the safety of cable use.
Style
Conductor Preparation: First, strictly screen aluminium raw materials to remove impurities to ensure the purity of aluminium. Then put the aluminium raw materials into a melting furnace for melting, control the melting temperature and time to completely melt the aluminium and remove gases and impurities. The molten aluminium liquid is made into aluminium rods through a casting and rolling process, and the diameter of the aluminium rods must meet the requirements of subsequent processing. Next, the aluminium rods are drawn into Aluminium Wires of the required diameter through a wire drawing machine. During the wire drawing process, control the drawing speed and tension to ensure the dimensional accuracy and surface quality of the aluminium wires. Finally, strand multiple aluminium wires together in a certain stranding way to form an Aluminium Conductor. During stranding, ensure the roundness and tightness of the conductor to ensure uniform and stable conductivity.
Insulation Layer Extrusion: Add XLPE materials into the extruder and heat to melt the materials. The molten XLPE material is uniformly extruded and coated on the outside of the aluminium conductor through a die under the pressure of the extruder to form an insulation layer. During the extrusion process, accurately control the extrusion temperature, extrusion speed, and die size to ensure that the insulation layer has a uniform thickness, a smooth surface, and is closely combined with the conductor without defects such as bubbles and wrinkles. The extruded Insulated Cores need to be cooled in a cooling water tank to quickly solidify and shape the insulation layer.
Cabling: Strand four cores covered with insulation layers in the specified stranding direction and pitch for cabling. During cabling, to ensure the roundness and structural stability of the cable, filling materials, usually polypropylene ropes, may be added in the center. During the cabling process, control the tension of each core to make the core stranding uniform and tight, avoiding looseness or distortion. After cabling, a layer of non-woven fabric or other materials may be wrapped around the outside to enhance the structural stability of the cable.
Sheath Extrusion (if any): If the cable is designed with a sheath, after cabling is completed, sheath extrusion is required. Add sheath materials (such as PVC) into another extruder, heat and melt them, then extrude and coat them on the outside of the cabled cores to form a sheath. The process requirements for sheath extrusion are similar to those for insulation layer extrusion. It is necessary to ensure that the sheath has a uniform thickness, a smooth surface, and is closely combined with the internal structure to protect the internal cores.
Inspection and Testing: The finished cables need to undergo a series of strict inspection and testing. Appearance inspection mainly checks whether the surface of the cable is damaged, whether the insulation layer is uniform, and whether there are defects such as bubbles; dimensional inspection measures whether the outer diameter of the cable, insulation layer thickness, conductor diameter, etc., meet the standard requirements; electrical performance testing includes insulation resistance testing, withstand voltage testing, etc., to ensure that the insulation performance and electrical safety performance of the cable meet the standards; mechanical performance testing such as tensile strength and elongation at break tests the mechanical strength of the cable to meet the use requirements. Only cables that pass all inspection and testing can leave the factory.
Packaging Materials: Cable reels are mainly used as packaging containers, and there are two types of cable reels: wooden and metal. Wooden cable reels have low cost and light weight but relatively weak load-bearing capacity, suitable for cables with small cross-sections and light weights; metal cable reels have strong load-bearing capacity and good durability, suitable for cables with large cross-sections and heavy weights. On the cable reels, the outer layer of the cable is wrapped with a layer of plastic film, which can play a role in moisture-proof and dust-proof, protecting the cable surface from pollution and damage. For some short-length cables, strong cartons can also be used for packaging. Buffer materials such as foam boards and bubble films are placed inside the cartons to prevent the cables from colliding with each other during transportation.
Packaging Method: Wind the cable neatly on the cable reel. During winding, ensure that the cable is arranged closely without overlapping or twisting to avoid extrusion damage to 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 high-strength ropes to prevent the cable from loosening and slipping during transportation. The cable reel will be marked with the cable's model, specification, length, production date, manufacturer, and other information for easy identification and traceability. For cables of different specifications, cable reels of appropriate sizes are selected for packaging to improve packaging efficiency and transportation safety.
Transportation Methods: Select appropriate transportation methods according to the transportation distance, the number of cables, and the traffic conditions at the customer's location. Road transportation is generally used for short-distance transportation, using trucks. Road transportation has high flexibility and can directly deliver cables to the customer's designated location, 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 transport volume, relatively low cost, and good stability, suitable for transporting large quantities of cables; long-distance road transportation can cover a wider range of areas and is more applicable to places where railway transportation is inconvenient.
Transportation Precautions
Loading: When loading cables, use special hoisting equipment such as cranes and forklifts to avoid damage to cables or cable reels caused by manual handling. The cable reels should be placed stably in the carriage of the transport vehicle to ensure a stable center of gravity and prevent tilting or toppling. Leave a certain gap between multiple cable reels to avoid mutual collision and friction. For large cable reels, use steel wires or chains to fix them on the carriage, and the fixed points must be firm and reliable.
Protection: During transportation, take protective measures to prevent the cables from being exposed to direct sunlight, rain, snow, and high-temperature exposure. In high temperatures in summer, a sunshade cloth can be covered over the cables; in rainy and snowy weather, the cables must be completely covered with rainproof cloth. At the same time, avoid contact between the cables and sharp objects to prevent the cable sheath from being cut. The transport vehicle should drive smoothly, avoiding sudden braking and sharp turns to reduce the shaking of the cable reels.
Unloading: When unloading cables, also use special hoisting equipment to lift and place them gently. It is strictly forbidden to directly push the cable reels off the vehicle to prevent damage to the cables and cable reels. The unloading location should be a flat and solid ground, avoiding unloading on soft and uneven ground to prevent the cable reels from toppling. After unloading, place the cable reels stably and mark them to prevent accidental collision.
