Conductor Material: Both cables use aluminum as the conductor material. Aluminum has good electrical conductivity and can meet the basic requirements of power transmission. At the same time, the density of aluminum is small, making the overall weight of the cable light, which not only reduces transportation costs but also reduces the labor intensity during the laying process. Compared with copper, the price of aluminum is relatively low, which helps to reduce the production cost of the cable and improve the cost performance of the product.

Insulation layer material: The insulation layer is made of temperature-resistant and anti-aging materials, usually cross-linked polyethylene (XLPE). This material has excellent electrical insulation performance, which can effectively prevent current leakage and ensure the safe operation of the cable. At the same time, cross-linked polyethylene has good temperature resistance, can maintain stable performance in a relatively high temperature environment, and the applicable temperature range is generally -40℃ to 90℃. In addition, it also has strong anti-aging performance, can resist the erosion of oxygen, ultraviolet rays and other factors, and prolong the service life of the cable.

Armored layer material: The armored layer generally uses Steel Tape or Aluminum Tape. Steel tape armoring has high mechanical strength and can effectively resist external mechanical damages such as impact and rolling, suitable for scenarios with high requirements for mechanical protection such as underground direct burial. Aluminum tape armoring has both certain mechanical strength and good corrosion resistance, and its weight is relatively light, suitable for some laying environments with requirements on weight. The design of the armored layer not only enhances the mechanical performance of the cable but also improves the corrosion resistance and moisture resistance of the cable, enabling it to operate reliably in complex environments.

Style: Both cables have a circular structure, which has certain advantages in the production and laying process. The circular structure allows the insulation layer and armored layer of the cable to be evenly distributed, ensuring the stability of the electrical and mechanical properties of the cable. At the same time, circular cables are easier to pass through pipes and cable trays during laying, reducing the resistance during the laying process.

Conductor drawing: First, aluminum ingots are made into aluminum rods through smelting, rolling and other processes, and then the aluminum rods are drawn into Aluminum Wires of the required diameter through a wire drawing machine. During the drawing process, it is necessary to strictly control the drawing speed and tension to ensure the dimensional accuracy and mechanical properties of the Aluminum Wires. The drawn aluminum wires also need to be annealed to eliminate internal stress and improve their Flexibility and conductivity.

Conductor stranding: Multiple aluminum wires are stranded together according to certain rules to form conductors of phase wires and neutral wires. During the stranding process, it is necessary to ensure the tightness and roundness of the conductor to reduce the resistance and eddy current loss of the conductor. The surface of the Stranded Conductor should be smooth and flat, without burrs and cracks, to ensure good electrical performance.

Insulation extrusion: An extruder is used to evenly coat the Insulation Material (such as cross-linked polyethylene) on the surface of the conductor 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 a uniform thickness, a smooth surface, and is closely combined with the conductor. The quality of the insulation layer directly affects the electrical insulation performance of the cable, so strict quality control is required in this link.

Cabling: Three phase wires and one neutral wire are stranded together according to a certain pitch to form the cable core. During the cabling process, it is necessary to add filling materials in the middle of the cable core to ensure the roundness and stability of the cable core. The filling material is usually polypropylene rope, etc., which has certain flexibility and corrosion resistance.

Armoring: An armored layer is coated outside the cable core. If steel tape armoring is adopted, the steel tape needs to be wrapped around the surface of the cable core through an armoring machine, and welded or 咬合 processed to ensure the firmness of the armored layer. If aluminum tape armoring is adopted, it is generally wrapped longitudinally or around, and the aluminum tape is bonded with the cable core with an adhesive. During the armoring process, it is necessary to control the overlap and tension of the armored layer to ensure the protective effect of the armored layer.

Sheath extrusion: Finally, a sheath layer is extruded outside the armored layer, and the sheath material is usually polyethylene (PE). The sheath layer can further protect the cable from the influence of the external environment, such as corrosion and moisture. During the extrusion process, it is also necessary to control the temperature, speed and pressure to ensure the quality of the sheath layer.

Quality inspection: Strict quality inspection is required in all links of the production process, including the size and resistance of the conductor, the thickness, dielectric loss, voltage resistance performance of the insulation layer, and the quality of the armored layer, etc. The finished cables also need to undergo sampling inspection, such as partial discharge test and aging test, to ensure that the products meet the relevant electrical safety standards and technical requirements.

Packaging materials: Cables are usually packaged with wooden reels or iron reels. Wooden reels are made of high-quality pine or fir, which have certain strength and toughness, and can bear the weight of the cable and the impact force during transportation. Iron reels are welded with high-strength steel, which have higher strength and are suitable for packaging long-length and heavy-weight cables. Both wooden reels and iron reels have their surfaces treated with anti-corrosion to prolong their service life.

Packaging method: The cable is neatly wound on the wooden reel or iron reel. During the winding process, it is necessary to control the winding tension to avoid excessive stretching or squeezing of the cable. The two ends of the cable need to be wrapped with plastic film or linen to prevent the ends from being damaged and damp. On the side of the wooden reel or iron reel, the model, specification, length, weight, production date and other information of the cable will be marked to facilitate users' identification and acceptance.

Packaging requirements: The packaging should be firm and reliable, which can prevent the cable from loosening, wearing or being damaged during transportation and storage. For exported products, the packaging also needs to meet international transportation standards and the import requirements of relevant countries, such as using fumigated wooden reels.

Transportation methods: According to the quantity, length and transportation distance of the cables, road transportation, railway transportation or water transportation can be selected. Road transportation has the characteristics of high flexibility and door-to-door service, suitable for short-distance transportation and small-batch goods. Railway transportation is suitable for long-distance and large-batch goods transportation, with the advantages of large transportation volume and low cost. Water transportation is suitable for transnational transportation or transportation in coastal areas, and can transport long-length and heavy-weight cables.

Transportation precautions: During transportation, it is necessary to avoid severe impact, vibration and extrusion of the cable. The cable reel should be placed horizontally, and it is strictly forbidden to invert or tilt to prevent the cable from sliding off the reel. During loading and unloading, special hoisting equipment should be used, and the hoisting point should be located at the axis of the cable reel to avoid damaging the cable reel and the cable. During transportation, attention should also be paid to moisture-proof, sun-proof and anti-corrosion. In case of rain, rain cloth should be covered.

Transportation time: The transportation time varies according to the transportation method and distance. Road transportation generally arrives within [X]-[X] days (the specific time depends on the distance), railway transportation takes about [X]-[X] days, and water transportation takes a longer time, usually [X]-[X] days (the specific time depends on the route and port conditions).
