(3) Material and Style
The 600V XLPE insulated PVC sheathed CVD, CVT, CVq cables fully consider performance, safety and practicality in material selection and style design.
The conductor is made of high-purity electrolytic copper with a purity of more than 99.95%. This high-purity copper has excellent electrical conductivity, high conductivity, which can effectively reduce the loss during current transmission and improve the efficiency of power transmission. At the same time, high-purity electrolytic copper also has good ductility and flexibility, so that the cable is not easy to break during bending and laying, ensuring the service life and stability of the cable.
The insulation layer is made of cross-linked polyethylene (XLPE) material. After cross-linking treatment, the XLPE material forms a three-dimensional network structure, which makes it have excellent temperature resistance and can work stably in the environment of -40℃ to 90℃. Whether in cold winter or hot summer, it can maintain good insulation performance. In addition, XLPE also has excellent aging resistance and insulation strength, which can effectively resist the risk of electrical breakdown and ensure the safe operation of the cable.
The outer sheath is made of polyvinyl chloride (PVC) material. The PVC sheath has good wear resistance, which can protect the internal structure of the cable from external mechanical damage, such as friction and collision with other objects during laying. At the same time, it also has excellent corrosion resistance, which can resist the erosion of acids, alkalis, salts and other chemical substances, and prolong the service life of the cable. Moreover, PVC material has certain flame retardant properties, which can delay the spread of fire in case of fire, and gain time for personnel evacuation and fire rescue.
In terms of style, the cable adopts a circular structure design. The circular structure makes the cable bear force evenly during laying, which is convenient for 穿梭 and installation in narrow spaces such as cable trays and pipelines, improving the convenience of construction. The surface of the cable is smooth and flat, with no obvious protrusions and depressions, which is not only beautiful, but also can reduce the resistance during laying, and is also convenient for cleaning and maintenance. Cables of different models are also distinguished in color. The CVD model is usually black, the CVT model is gray, and the CVq model is brown, which is convenient for users to identify during selection and installation.
(4) Production Process
The production process of 600V XLPE insulated PVC sheathed CVD, CVT, CVq cables strictly follows high-standard process requirements to ensure that each 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 oil and impurities on the surface, they enter the wire drawing process. The copper rod is drawn into a
Copper Wire of the required diameter through a wire drawing die. During the wire drawing process, it is necessary to strictly 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 according to a certain stranding method to form a conductor. During the stranding process, it is necessary to control the stranding pitch and tension to make the conductor structure tight and stable.
The next step is the extrusion process of the insulation layer. The prepared conductor is sent to the extruder, and a layer of cross-linked polyethylene (XLPE) insulation layer is extruded outside the conductor. Before extrusion, the XLPE material needs to be pretreated to remove moisture and impurities to ensure the quality of the insulation layer. During the extrusion process, it is necessary to accurately control the extrusion temperature, pressure and speed to ensure that the thickness of the insulation layer is uniform, the surface is smooth, and it is closely combined with the conductor, without defects such as bubbles and impurities. After the extrusion is completed, the insulation layer is cross-linked, usually by warm water cross-linking or steam cross-linking, so that the XLPE molecules form a stable three-dimensional network structure, thereby improving its temperature resistance and mechanical properties.
Then is the extrusion process of the sheath. The cable core with the insulation layer is sent to the sheath extruder, and a layer of polyvinyl chloride (PVC) sheath is extruded outside the insulation layer. The PVC material needs to be fully mixed and plasticized before extrusion to ensure the uniformity and quality of the sheath. During the extrusion process, it is also necessary to control the temperature, pressure and speed to ensure that the thickness of the sheath is uniform, the surface is flat, and it is closely attached to the insulation layer to play an effective protective role. When extruding the sheath of cables of different models, the thickness and formula of the sheath will be adjusted according to the design requirements to meet their specific performance needs.
Finally, there is the inspection and packaging process of the finished product. The produced cables need to undergo a series of strict inspections, including appearance inspection, size measurement, insulation resistance test, voltage resistance test, mechanical performance test, etc. Only cables whose various indicators meet relevant standards and regulations can be judged as qualified products. After passing the inspection, the cable is cut according to the specified length and packaged in a suitable way for storage and transportation.
II. General Product Information
(1) Packaging
In order to ensure that the 600V XLPE insulated PVC sheathed CVD, CVT, CVq cables are not damaged during storage and transportation, a scientific and reasonable packaging method is adopted.
For long-length 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 must be 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 to prevent the cable from being eroded by moisture, rain, etc. 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.
For small-length cables or samples, strong cartons are used for packaging. The cartons are made of high-strength corrugated paper, which has good compressive performance. Inside the carton, moisture-proof paper and buffer materials such as foam boards and bubble films are placed to reduce the vibration and collision of the cable during transportation and protect the appearance and performance of the cable. The outside of the carton is also printed with relevant product information, which is convenient for handling and storage.
In addition, the two ends of each cable will be sealed with special sealing caps to prevent dust, moisture, etc. from entering the inside of the cable and affecting the quality of the cable.
(2) Transportation
The transportation of 600V XLPE insulated PVC sheathed CVD, CVT, CVq cables needs to strictly abide by relevant regulations and procedures to ensure the safe transportation of the cables.
Before transportation, the packaging of the cable should be carefully checked to ensure that the packaging is intact and the cable reel or carton is firm and reliable. For cables packaged with cable reels, check the fixing of the cable reel to ensure that it will not slide or topple during transportation.
The transport vehicle should be a truck or trailer in good condition with sufficient load-carrying capacity. When loading the cable, special hoisting equipment should be used to place the cable reel or carton on the vehicle smoothly to avoid violent collision and extrusion. For multiple cable reels, the placement position should be reasonably arranged to ensure the stability of the vehicle's center of gravity, and the cable reels should be fixed firmly with ropes or chains to prevent movement 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, the cable should be covered, such as 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 regularly check the fixing of the cable and whether the packaging is intact. If any abnormal situation is found, he should stop in time to handle it to ensure that the cable can reach the destination safely.
