I. Information Related to the Product Itself
(I) Specification Parameters
The Na2xy 4×240 0.6/1kV
Power Cable has clear and standardized settings in terms of specification parameters. It adopts a 4-core design, with each core having a cross-sectional area of 240mm², enabling it to meet the power distribution requirements of the three-phase four-wire system and having a current-carrying capacity suitable for medium and high-power scenarios. Under the voltage level of 0.6/1kV, after professional testing, its continuous current-carrying capacity can meet the needs of medium and high-power power transmission at an ambient temperature of 25°C, and it can stably supply power to relevant electrical equipment and lines.
The overall outer diameter of the cable is accurately calculated and controlled, which not only ensures the reasonable arrangement of internal cores, insulation, sheaths and other structures, but also can adapt to common laying pipes and spaces. The thickness of the insulation layer meets relevant industry standards, and the cross-linked polyethylene (XLPE) insulation layer can effectively withstand the rated voltage, avoiding potential safety hazards such as electric leakage. The thickness of the sheath layer is also optimized. The polyvinyl chloride (PVC) sheath not only can play a good protective role for the internal structure, but also will not excessively increase the overall weight and outer diameter of the cable.
In addition, the electrical performance parameters such as conductor resistance and insulation resistance of the cable are within the specified qualified range. The conductor is made of aluminum material, and its resistance value meets the relevant standards for
Aluminum Conductors, which can reduce power loss during power transmission. The insulation resistance value is high, ensuring the insulation effect of the insulation layer and the safety of power transmission.
(II) Characteristic Uses
Due to its own performance characteristics, the Na2xy 4×240 0.6/1kV power cable has a wide range of characteristic uses. It can play an important role in the distribution trunk lines of industrial plants. There are usually a large number of large mechanical equipment in industrial plants, which have a large demand for electricity. The 4-core design and 240mm² cross-section of the cable can meet the power distribution requirements of the three-phase four-wire system, stably transmit electricity from the distribution room to various production areas, and ensure the normal operation of mechanical equipment.
In terms of power transmission in large buildings, such as large shopping malls, office buildings, hotels, etc., there are many internal electrical equipment and large power loads. The cable can be used as the main distribution trunk line in the building, distributing electricity from the main distribution box to the distribution rooms on each floor, and then distributing it from the floor distribution rooms to various electrical terminals, such as lighting, air conditioners, elevators, etc., to ensure the stable and reliable power supply in the building.
Outdoor small and medium-sized power distribution projects are also important application scenarios. For example, in outdoor power distribution lines of some outdoor industrial parks and large communities, the cable can adapt to outdoor environmental conditions and transmit electricity from substations or distribution rooms to various power consumption points. At the same time, in some outdoor temporary power consumption occasions, such as temporary power distribution lines at large event sites, it can also meet the short-term medium and high-power power transmission needs.
In addition, in some occasions that have certain requirements for cable performance but do not need excessive configuration, such as workshop
Power Lines of small and medium-sized factories and street lamp power supply trunk lines of urban roads, the cable has become an ideal choice with its balanced performance and economy.
(III) Material and Style
In terms of materials: The conductor of the cable is made of aluminum (Al) material. Aluminum has the characteristic of light weight, which makes the cable more convenient in transportation and laying, and can reduce construction difficulty and cost. At the same time, the cost of aluminum is relatively low, which helps to control the overall price of the cable and improve the cost performance of the product under the premise of ensuring certain electrical conductivity.
The insulation layer uses cross-linked polyethylene (XLPE). This material has excellent temperature resistance and can maintain a stable insulation effect in a relatively high temperature environment. Even when the cable runs for a long time and generates a certain amount of heat, it will not easily have problems such as insulation aging and breakdown. Moreover, XLPE has excellent insulation performance, with small dielectric constant and large insulation resistance, which can effectively prevent current leakage and ensure the safety of power transmission.
The sheath is made of polyvinyl chloride (PVC) material. PVC has good moisture-proof performance, which can prevent moisture from entering the cable and avoid erosion to conductors and insulation layers. At the same time, it also has wear-resistant characteristics, which can resist external friction and collision during cable laying and use, and protect internal cores, insulation layers and other structures from damage. In addition, PVC also has certain chemical corrosion resistance and can maintain stable performance in general acid-base environments.
In terms of style: The cable adopts a 4-core design, which meets the power distribution requirements of the three-phase four-wire system. Among them, three cores are used as phase lines to transmit electric energy, and one core is used as a neutral line for current loops, meeting the power distribution requirements of most industrial and civil power systems.
The appearance of the cable is round with a smooth surface. This style is not only convenient for laying in pipes, reducing resistance during laying, but also can make the cable more regular when stacked and transported, saving space. Moreover, the circular cross-section design can make the force on each part of the cable more uniform, improving the overall mechanical strength of the cable.
(IV) Production Process
The production process of Na2xy 4×240 0.6/1kV power cable strictly follows relevant process standards to ensure product quality. In the conductor production link, high-quality aluminum materials are first selected, 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 wire drawing equipment. After that, multiple
Aluminum Wires are stranded according to certain rules to form a conductor core with a cross-section of 240mm². During the stranding process, parameters such as stranding pitch are strictly controlled to ensure the roundness and electrical conductivity of the conductor.
Insulation layer extrusion is one of the key processes. Special extrusion equipment is used to heat and melt the cross-linked polyethylene (XLPE) material, then uniformly extrude and wrap it around the conductor core to form an insulation layer. During the extrusion process, parameters such as extrusion temperature, speed and pressure are accurately controlled to ensure that the insulation layer has uniform thickness, smooth surface, and is closely combined with the conductor core without defects such as bubbles and impurities. After extrusion, the insulation layer is cross-linked. By heating, the XLPE molecules form a three-dimensional network structure, thereby improving the temperature resistance, mechanical strength and insulation performance of the insulation layer.
In the cabling process stage,
4 Cores wrapped with insulation layers are cabled according to a certain stranding method. During the stranding process, a suitable filling material is filled between the cores to keep the cable cross-section round. At the same time, a layer of binding tape is wrapped around the cabled cable to fix the position of the cores and prevent them from shifting during subsequent processing and use.
In the sheath extrusion link, an extruder is used to extrude polyvinyl chloride (PVC) material and wrap it around the cabled cable to form a sheath layer. The extrusion parameters must also be controlled to ensure that the sheath layer has uniform thickness, flat surface and is closely attached to the internal structure. The extruded cable is cooled in a cooling water tank to make the sheath layer solidify and form quickly.
Finally, the finished cable undergoes a series of strict inspections, including appearance inspection, size measurement, electrical performance testing (such as conductor resistance test, insulation resistance test, withstand voltage test, etc.) and mechanical performance testing. Only cables that meet relevant standards in all indicators can leave the factory.
II. General Product Information
(I) Packaging
The packaging design of Na2xy 4×240 0.6/1kV power cable fully considers the needs of protecting the cable and facilitating transportation and storage. In terms of packaging materials, wooden cable reels or steel cable reels are usually used. Wooden cable reels have relatively low cost and light weight, and are suitable for short-distance transportation and packaging of small batches of cables. It has certain cushioning performance and can reduce vibration and collision to the cable during transportation. Steel cable reels have higher strength and bearing capacity, and are suitable for long-distance transportation and packaging of large batches of cables, which can better bear the weight of the cable and external impact during transportation.
In terms of packaging methods, the cable will be neatly wound on the cable reel. Appropriate tension is maintained during winding to ensure that the cable will not be loose or twisted. A layer of moisture-proof film will be wrapped around the outer layer of the cable, which can effectively block the entry of external water vapor and prevent the cable from getting damp. For wooden cable reels, wooden baffles are installed on the edges and sides to avoid damage to the cable due to collision during transportation and handling. On the side of the cable reel, the model (Na2xy), specification (4×240mm²), voltage level (0.6/1kV), length, production date, manufacturer and other information of the cable are clearly marked for easy identification and traceability by users.
The packaging must also meet certain requirements. The packaged cable must be guaranteed not to be damaged under normal transportation and storage conditions. The size and strength of the cable reel must match the length and weight of the cable to ensure that it will not be deformed or damaged during hoisting and handling. At the same time, the packaging should be easy to load and unload to improve logistics efficiency.
(II) Transportation
When transporting Na2xy 4×240 0.6/1kV
Power Cables, an appropriate transportation method needs to be selected. According to the transportation distance and the amount of transportation, road transportation, railway transportation, etc. can be chosen. Truck transportation is generally used for short-distance transportation. Truck transportation has high
Flexibility and can directly deliver the cable to the destination, reducing transshipment in intermediate links. For long-distance transportation, railway transportation can be chosen. Railway transportation has good stability and large transportation volume, which is suitable for long-distance transportation of large quantities of cables.
There are many precautions during transportation. First of all, the cable must be placed stably during loading to avoid tilting and inversion. Special hoisting equipment is used for loading and unloading, and the hoisting point must be selected at the special hoisting position of the cable reel to prevent the cable reel from being deformed or the cable from slipping. A certain gap must be left between the cable reels to avoid mutual extrusion and collision.
During transportation, protective measures must be taken to prevent the cable from being affected by harsh weather such as exposure to the sun, rain, and freezing. Coverings such as tarpaulins can be used to cover the cable to avoid sheath aging caused by direct sunlight and prevent rainwater from entering the cable. At the same time, it is necessary to avoid severe vibration and impact on the cable. Drivers must drive steadily during driving and avoid sudden braking and sharp turns.
Obvious transportation signs such as "Handle with Care", "Moisture-proof" and "No Rolling" must be posted on the transport vehicle to remind transport and loading and unloading personnel to pay attention to relevant matters. During transportation, the status of the cable must be checked regularly, and problems must be dealt with in a timely manner.
