(3) Material and Style
The N2X-Oh Cable 3*240mm² copper power building cable fully considers the needs of building power transmission in material selection and style design, combining performance and practicality.
The conductor uses high-purity electrolytic copper with a purity of more than 99.95%. This high-purity copper material has many advantages. Firstly, its electrical conductivity is extremely excellent, with a conductivity of up to 58MS/m or more, which can minimize power loss during transmission and improve power transmission efficiency. Secondly, high-purity electrolytic copper has good ductility, which can withstand a certain degree of bending and stretching during cable production and laying, and is not easy to break, ensuring the integrity of the cable. In addition, it also has excellent oxidation resistance. During long-term use, the surface of the conductor is not easy to oxidize to form an oxide layer, which reduces the resistance increment at the joint and prolongs the service life of the cable.
The insulation layer is made of cross-linked polyethylene (XLPE) material, which is a high-quality
Insulation Material commonly used in
Power Cables. It has excellent aging resistance, can maintain good insulation performance during long-term use, and is not easy to age and deteriorate over time. Its temperature resistance range is wide, can withstand temperature changes from -40°C to 90°C, and can adapt to the complex temperature environment inside the building. Whether in cold winter or hot summer, it can maintain a stable insulation effect. At the same time, cross-linked polyethylene material has strong resistance to mechanical wear. During building construction, the cable may be subjected to mechanical effects such as wall extrusion and cable tray friction. The insulation layer can effectively resist these wears and protect the conductor from damage.
The sheath of the cable is made of polyvinyl chloride (PVC) material, which tightly wraps around the outside of the insulation layer, forming a strong protective barrier. Polyvinyl chloride material has good mechanical strength and corrosion resistance, which can protect the internal structure of the cable from the influence of the external environment, such as preventing moisture, dust, corrosive gases, etc. from entering the inside of the cable, ensuring the normal operation of the cable. In addition, the sheath also has a certain flame retardant performance. In case of fire and other accidents, it can delay the spread of the fire and gain time for personnel evacuation and fire fighting.
In terms of style, the cable has a circular structure with an overall compact design. The circular structure makes the cable bear force evenly during laying, facilitating 穿梭 in narrow spaces such as cable trays and pipelines, and reducing laying difficulty. The surface of the cable is smooth and flat, with no obvious protrusions or depressions. This design is not only beautiful but also can reduce friction with other objects during laying, reducing the risk of cable damage. At the same time, the smooth surface is also easy to clean and maintain.
(4) Production Process
The production process of N2X-Oh Cable 3*240mm² copper power building cable strictly follows high-standard production processes to ensure that each section of the cable has excellent quality.
The first step is the conductor preparation process. High-purity electrolytic copper rods are selected as raw materials. After cleaning to remove surface impurities and oil, they enter the wire drawing process. During the wire drawing process, through a series of dies of different specifications, the copper rods are drawn into
Copper Wires of the required diameter. In the wire drawing process, it is necessary to precisely control the wire drawing speed and the temperature of the die to ensure that the diameter of the copper wire is uniform, the surface is smooth, and at the same time, the copper wire has good mechanical properties and electrical conductivity. After wire drawing, multiple copper wires are stranded to form a conductor core. During the stranding process, it is necessary to control the stranding pitch and tension to ensure that the structure of the conductor core is stable and the electrical conductivity is uniform.
The next step is the extrusion process of the insulation layer. The prepared conductor core is sent to the extruder, and a layer of cross-linked polyethylene (XLPE) insulation layer is extruded outside the conductor core. Before extrusion, it is necessary to pretreat the cross-linked polyethylene material to remove moisture and impurities. During the extrusion process, it is necessary to strictly control the extrusion temperature, pressure and speed to ensure that the thickness of the insulation layer is uniform, closely combined with the conductor core, and free of defects such as bubbles and impurities. After the extrusion of the insulation layer is completed, cross-linking treatment is required. By heating, the cross-linked polyethylene molecules undergo a cross-linking reaction to form a three-dimensional network structure, thereby improving the temperature resistance, aging resistance and mechanical strength of the insulation layer.
Then is the cabling process. The three wire cores with completed insulation layer extrusion are stranded according to a certain stranding method to form the core of the three-
Core Cable. During the stranding process, it is necessary to precisely control the stranding pitch and tension to ensure that the core structure is stable and the shape is regular. At the same time, during the stranding process, filling materials will be added in the middle of the core to make the structure of the core more compact and improve the roundness of the cable.
Finally, the sheath extrusion and finished product inspection processes are carried out. The
Stranded Core is sent to the sheath extruder, and a layer of polyvinyl chloride (PVC) sheath is extruded outside the core. During the extrusion process, it is also necessary to control the extrusion parameters to ensure that the thickness of the sheath is uniform, the surface is smooth, and it is closely combined with the core. After the sheath extrusion is completed, the cable undergoes a series of strict inspections, including appearance inspection, size measurement, conductor DC resistance test, insulation resistance test, voltage resistance test, etc. Only cables that pass all inspection items can be judged as qualified products and sold on the market.
II. General Product Information
(1) Packaging
In order to ensure that the N2X-Oh Cable 3*240mm² copper power building cable is not damaged during transportation and storage, a scientific and reasonable packaging method is adopted.
For coiled cables, wooden cable reels are usually used for packaging. The wooden cable reels are made of high-quality hardwood, which has high strength and stability, and can bear the weight of the cable and the external impact during transportation. The cable is tightly wound on the cable reel, and the tension is strictly controlled during the winding process to avoid loosening or excessive stretching of the cable. On the outside of the cable reel, a thick layer of moisture-proof plastic film is wrapped, which can effectively prevent moisture, rainwater, etc. from invading the cable and protect the insulation layer and conductor of the cable from moisture damage. At the same time, the model, specification, length, weight, production date, manufacturer and other information of the product will be clearly marked on the side of the cable reel, which is convenient for users to identify and manage during receiving and storage.
For some small-length cables or samples, strong cartons are used for packaging. The cartons are made of high-strength corrugated paper, which has certain compressive performance. Inside the carton, moisture-proof paper and buffer materials such as foam boards and bubble films are placed. These materials can reduce the vibration and collision of the cable during transportation and protect the appearance and performance of the cable from damage. The outside of the carton is also printed with relevant product information, which is convenient for handling and storage.
During the packaging process, the two ends of the cable will also be sealed, usually with special plastic end caps or sealing tape to prevent dust, impurities, etc. from entering the inside of the cable and affecting the performance of the cable.
(2) Transportation
The transportation of N2X-Oh Cable 3*240mm² copper power building cable requires a series of strict measures to ensure the safety and integrity of the cable.
The choice of transport vehicles is crucial, and trucks or trailers in good condition with sufficient load-carrying capacity should be selected. Before loading the cable, the carriage of the vehicle should be thoroughly cleaned to ensure that there are no sharp objects, corrosive substances, etc. in the carriage, so as not to damage the packaging of the cable and the cable itself. For coiled cables, special hoisting equipment is used for loading and unloading. During the hoisting process, the cable reel should be kept stable to avoid violent shaking and collision. After placing the cable reel in the carriage, it should be firmly fixed with strong ropes or chains to prevent sliding, rolling, etc. during transportation.
During transportation, the cable should be protected from direct sunlight, rain, high temperature, low temperature and other extreme environments. For long-distance transportation, it is necessary to cover the cable with a tarpaulin to protect the cable from damage by the external environment. At the same time, the transportation route should be reasonably planned, and roads with good and flat conditions should be chosen as much as possible to reduce 颠簸 and vibration during transportation. During transportation, the driver should stop regularly to check the fixing of the cable and whether the packaging is intact. If any abnormal situation is found, measures should be taken in time to deal with it to ensure that the cable can reach the destination safely.
In addition, traffic rules must be observed during transportation, driving at a limited speed, avoiding sudden braking, sharp turns and other operations to reduce the impact on the cable. For some special road sections, such as bridges and tunnels, attention should be paid to height limits, weight limits and other regulations to ensure transportation safety.
