4×50mm² Cable
Small shop power distribution: Small shops such as convenience stores, flower shops, and small restaurants have electrical equipment mainly including lighting, cash registers, air conditioners, and small refrigerators. The total power of these equipment is relatively small. The 4×50mm² cable can stably supply power to these equipment to ensure the normal operation of the shop. Moreover, the cable of this specification has a moderate size, which is convenient for wiring in the limited space of the shop and will not take up too much space.
Household incoming main line: There are many electrical equipment in the family, including refrigerators, TVs, washing machines, air conditioners, etc. The incoming main line needs to bear the power supply of all equipment in the family. The 4×50mm² cable can meet the electricity demand of ordinary families and introduce external power into the internal power distribution system of the family safely and stably. At the same time, its steel tape armored structure can maintain good performance even in places that may be slightly collided, such as walls and floors, during family wiring.
4×70mm² Cable
Total power distribution of multi - storey residential buildings: There are many households in multi - storey residential buildings, and the total power load is relatively large. The 4×70mm² cable can be used as a total power distribution line to introduce external power and then distribute it to each unit, providing stable power support for the entire multi - storey residential building. During the power distribution process, the cable needs to be wired through some public areas, and the steel tape armored layer can protect the cable from accidental collisions and other impacts.
Power supply for small industrial equipment: Small industrial equipment such as small machine tools, small compressors, and small fans need certain power when running. The 4×70mm² cable can meet the power demand of these equipment and ensure the normal start - up and operation of the equipment. In the industrial environment, there may be some mechanical vibration or collision risks around the equipment, and the steel tape Armored Cable can better adapt to this environment.
Common Application Scenarios
Material
Conductor: Aluminum is used as the conductor. Aluminum has good electrical conductivity and can transmit electricity efficiently. Compared with Copper Conductors, aluminum 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, aluminum has a low density, so the overall weight of the cable is relatively light, which is convenient for transportation and installation.
Steel tape armored layer: Steel tape is used as the armored material. Steel tape has high mechanical strength and toughness, which can provide effective mechanical protection for the cable and resist external forces such as extrusion, collision, and stretching. Moreover, the steel tape has good corrosion resistance and can maintain its protective performance for a long time in a general environment.
Insulation layer: Insulating materials such as cross - linked polyethylene (XLPE) or polyvinyl chloride (PVC) are usually used. These materials have good insulation performance, can effectively prevent current leakage, and ensure the safety of power transmission. At the same time, they also have certain temperature resistance and aging resistance, and can adapt to different use environments.
Sheath: The sheath material is generally polyvinyl chloride (PVC), etc., which has good wear resistance and corrosion resistance. It can protect the armored layer, insulation layer, and conductor inside the cable from damage caused by the external environment.
Style
Conductor Preparation: First, screen and purify the aluminum raw materials to remove impurities. Then, melt the aluminum raw materials, control the melting temperature and time, and obtain pure aluminum liquid. The aluminum liquid is made into aluminum rods through the casting and rolling process, and then the aluminum rods are drawn into Aluminum Wires of the required diameter through the wire drawing process. Finally, twist multiple Aluminum Wires together to form an Aluminum Conductor. During the twisting process, ensure the roundness and tightness of the conductor to ensure electrical conductivity.
Insulation Layer Extrusion: Add insulating materials (such as XLPE or PVC) into the extruder, heat and melt them, and then evenly extrude and coat them on the outside of the aluminum conductor through a mold to form an insulation layer. During the extrusion process, control parameters such as temperature and speed to ensure that the insulation layer has a uniform thickness, a smooth surface, is closely combined with the conductor, and has no defects such as bubbles and impurities. After extrusion, cool and solidify the Insulated Core.
Cabling: Twist four cores covered with insulation layers in a certain twisting way. During twisting, ensure that the positions of the cores are uniform and the tension is consistent to ensure the roundness and structural stability of the cable. Filling materials may be added during the cabling process to make the cable structure more compact.
Steel Tape Armoring: Perform steel tape armoring treatment on the outside of the cabled cable. Wrap the steel tape on the cable at a certain angle and tension through an armoring machine to form an armored layer. During the wrapping process, ensure that the overlap rate of the steel tape meets the requirements, and the armored layer is tight and flat without looseness, wrinkles, etc. Steel tape armoring can significantly improve the mechanical strength and impact resistance of the cable.
Sheath Extrusion: Extrude the sheath on the outside of the steel tape armored layer. Add the sheath material into the extruder, heat and melt it, and then extrude and coat it on the outside of the armored layer to form a sheath. During extrusion, control the process parameters to ensure that the sheath has a uniform thickness, a smooth surface, and is closely combined with the armored layer to play a good protective role.
Inspection and Testing: After production, conduct a series of inspection and testing on the cable. Including appearance inspection to check whether the surface of the cable is damaged and whether the armored layer is flat; dimension measurement to detect whether the outer diameter of the cable, the thickness of the insulation layer, and the thickness of the armored layer 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 standards; mechanical performance testing, such as compression and impact resistance testing, to test the protective effect of the armored layer. Only cables that pass all tests 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 are suitable for general transportation and storage; metal cable reels have higher strength and are suitable for long - distance transportation or heavier cables. On the cable reel, the outer layer of the cable is wrapped with a layer of plastic film, which plays a role in moisture proof and dust proof. For shorter cables, strong wooden boxes can also be used for packaging. Buffer materials are placed inside the wooden boxes to prevent the cables from being damaged by collision during transportation.
Packaging Method: Wind the cable neatly on the cable reel. During winding, ensure that the cable is arranged closely without distortion or overlap. After winding, wrap the entire cable tightly with plastic film, and then fix the cable on the cable reel with steel strips or ropes to prevent the cable from loosening during transportation. The cable reel will be marked with the cable's model, specification, length, manufacturer, production date, and other information for easy identification and traceability. For cables of different specifications, select cable reels of appropriate sizes for packaging.
Transportation Methods: Select appropriate transportation methods according to factors such as transportation distance and the number of cables. Road transportation is generally used for short - distance transportation, using trucks for transportation, which has high flexibility and can be directly delivered to the destination. For long - distance transportation, railway transportation or long - distance road transportation can be chosen. Railway transportation has a large transport volume and relatively low cost, 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 damage to cables or cable reels caused by manual handling. The cable reel should be placed stably on the transport vehicle and fixed firmly to prevent tilting or toppling. Leave a certain gap between multiple cable reels to avoid mutual collision and friction.
Protection: Take moisture - proof, sun - proof, and collision - proof measures during transportation. Cover the cable with rainproof cloth to prevent it from getting damp in the rain; avoid direct sunlight to prevent aging of the cable sheath; place buffer materials around the cable reel to prevent collision during transportation.
Unloading: When unloading cables, use hoisting equipment to lift and place them gently. It is strictly forbidden to push the cable reel directly off the vehicle. After unloading, place the cable reel on a flat and solid ground and fix it to prevent rolling.
