4X1c Cu XLPE Insulated Power Cable 16mm² Low Voltage

The 4X1c copper Core XLPE insulated low-voltage power cable has detailed and rigorous settings in terms of specification parameters, which are the key basis for its performance and applicable scenarios.

The cable adopts a 4-core design, with each core conductor having a cross-sectional area of 16mm². The 4-core structure design is not accidental, but to adapt to the three-phase four-wire power distribution system, where three cores serve as three-phase phase lines and the other as a neutral line. This structure can achieve efficient transmission of electrical energy, while ensuring the balance of the circuit, meeting the needs of simultaneous power supply for multiple devices, and avoiding equipment failures or power losses caused by three-phase imbalance. The 16mm² conductor cross-sectional area is obtained through precise calculation, and it can carry a certain range of rated current. In practical applications, this cross-sectional area of the conductor can effectively avoid excessive heat generation due to overload during long-term operation, thereby ensuring the stability of power transmission and reducing safety hazards caused by overheating.

As a low-Voltage Cable, its rated voltage is usually applicable to power distribution scenarios of 0.6/1kV and below. This voltage level fully complies with the safety standards of low-voltage systems and can be directly connected to distribution transformers, distribution boxes, and various electrical equipment without additional voltage conversion equipment, simplifying the structure of the power distribution system and improving the efficiency of power transmission.

In addition, the outer diameter of the cable is also clearly specified. A suitable outer diameter not only facilitates the laying and installation of the cable but also ensures that the cable has good heat dissipation performance during use. At the same time, the bending radius of the cable also has strict requirements, and different laying methods correspond to different bending radius standards. This is to avoid damaging the insulation layer and conductor of the cable due to excessive bending during installation, ensuring that the performance of the cable is not affected.

The insulation thickness of the cable is also one of the important specification parameters. The thickness of the cross-linked polyethylene (XLPE) insulation layer is precisely calculated to ensure that it has sufficient insulation strength, effectively preventing current leakage and ensuring the safe operation of the cable. Under normal working voltage, the insulation layer will not be broken down, providing reliable insulation protection for power transmission.

The 4X1c copper core XLPE insulated low-voltage power cable, with its excellent performance, has distinctive uses in many fields.

In the industrial field, this cable plays an important role. There are various types of mechanical equipment in factory workshops with different power levels, which have extremely high requirements for the stability of electricity. This cable can provide stable power supply for these mechanical equipment, ensuring the smooth progress of production. The power distribution lines of the production line also often use this cable, which can withstand the mechanical vibration and dust environment in the workshop. Even under long-term vibration and dust erosion, the performance of the cable will not be greatly affected, ensuring the continuous operation of the production line. For example, in automobile manufacturing workshops, various welding equipment, assembly machinery, etc., need stable power support, and this cable can meet the power needs of these equipment, providing reliable power guarantee for automobile production.

In commercial buildings, the application of this cable is also very extensive. Office buildings, shopping malls and other places have a large flow of people and many electrical equipment, such as central air conditioners, elevators, lighting systems, etc. These equipment have large power demand and require stable power supply. This cable can be used as the main power Distribution Cable to connect floor distribution boxes with these high-power equipment, ensuring that electricity can be transmitted efficiently and stably to all corners. In large shopping malls, from the lighting in the underground parking lot to the air conditioning system on the top floor, they all rely on this cable for power transmission, and its excellent performance ensures the normal operation of the shopping mall.

In civil scenarios, this cable is also indispensable. The power supply of residential communities is directly related to the daily life of residents. This cable is suitable for Underground Cable trench laying or wall concealed laying. UnderGround Cable trench laying can avoid physical damage to the cable from the outside and does not affect the beauty of the community; wall concealed laying can save space and make the indoor environment more tidy. It provides stable electricity for household appliances, lighting, etc. in residential buildings, ensuring residents' daily electricity use.

In addition, due to the strong weather resistance of the XLPE insulation layer, this cable can also be used for some outdoor low-voltage Overhead Lines or buried laying. The landscape lighting systems in parks and squares need to work in outdoor environments for a long time, facing the test of natural factors such as wind, sun, rain and snow. This cable can operate stably in such an environment for a long time without frequent maintenance, providing continuous power support for landscape lighting and creating a beautiful night landscape. In some outdoor construction sites, temporarily built power distribution lines also often choose this cable, which can adapt to the complex outdoor environment and ensure the normal power supply of construction equipment.

The 4X1c copper core XLPE insulated low-voltage power cable fully considers its performance requirements and use environment in terms of material selection and style design.

In terms of materials, the conductor is made of high-purity electrolytic copper with a purity of more than 99.9%. High-purity copper has extremely low resistivity, which means that during power transmission, the loss of electrical energy will be greatly reduced, thereby improving the efficiency of power supply. For industrial, commercial, civil and other scenarios with large electricity consumption, it can save a lot of electrical energy and reduce electricity costs. At the same time, Copper Conductors have excellent ductility and mechanical strength. After wire drawing, stranding and other processes, their performance is further improved. During installation, the cable needs to be bent, stretched and other operations, and the copper conductor can withstand these external forces without breaking or deforming, ensuring the installation quality and service life of the cable.

The insulation layer is made of cross-linked polyethylene (XLPE) material, which has significant advantages compared with traditional polyvinyl chloride (PVC) Insulation Materials. XLPE has excellent heat resistance and can operate stably in the environment of -40℃ to 90℃, which enables the cable to maintain good performance in high or low temperature environments. In industrial workshops with high temperatures in summer or outdoors with cold temperatures in winter, the cable will not be affected by temperature problems and can work normally. Its aging resistance is also very prominent, able to resist the erosion of oxygen, ultraviolet rays and other factors, and prolong the service life of the cable. Even in the long-term use process, the performance of the insulation layer will not decrease significantly, ensuring the safety and reliability of the cable. In addition, XLPE has high insulation strength and strong chemical corrosion resistance, able to resist the erosion of moisture, acid, alkali and other environmental factors, further expanding the application range of the cable.

In terms of style, the cable adopts a Multi-Core cabling design. 4 Conductors are twisted together, and the outside is wrapped with a layer of cross-linked polyethylene insulation layer to form a whole. This structure makes the cable have good Flexibility, which is convenient for laying and installation in various complex environments. It can be laid smoothly in narrow cable trenches or curved wall pipes. The appearance of the cable is usually black or gray, which is not only resistant to dirt but also can absorb a certain amount of heat, helping the cable to dissipate heat. At the same time, the surface of the cable is smooth, reducing the friction during laying and making installation more convenient.

In addition, the marking of the cable is very clear. The surface of the cable is printed with product model, specification, rated voltage, manufacturer and other information. These marks are convenient for users to identify and manage the cable, and also facilitate the maintenance and replacement of the cable.

The production process of 4X1c copper core XLPE insulated low-voltage power cable is complex and rigorous, and each process is carefully designed and strictly controlled to ensure product quality.

The first is the manufacturing process of the conductor. High-purity electrolytic copper is smelted and made into copper rods. The copper rod is drawn on a wire drawing machine for many times, and gradually drawn into Copper Wires of the required diameter. During the wire drawing process, it is necessary to strictly control the drawing speed and tension to ensure that the diameter of the copper wire is uniform and the surface is smooth. The drawn copper wire also needs to be annealed. Through heating and cooling processes, the internal stress of the copper wire is eliminated, and its flexibility and ductility are improved. Then, multiple copper wires are twisted according to a certain stranding method to form a conductor. The stranding process can improve the mechanical strength and flexibility of the conductor, and also reduce the impact of the skin effect, improving the conductive performance of the conductor. The Stranded Conductor needs to be surface treated to remove oil and impurities on the surface to ensure the cleanliness of the conductor.

Next is the extrusion and cross-linking process of the insulation layer. A special extruder is used to heat and melt the cross-linked polyethylene (XLPE) material, and then evenly extrude and coat it on the surface of the conductor to form an insulation layer. During the extrusion process, it is necessary to accurately control parameters such as extrusion temperature, speed and pressure to ensure that the insulation layer has uniform thickness, smooth surface, and is closely combined with the conductor without defects such as bubbles and impurities. The extruded Insulated Wire core needs to be cross-linked. Cross-linking is a key process for XLPE Insulation Materials. Through heating or radiation, chemical cross-linking is formed between XLPE molecular chains to form a three-dimensional network structure. The cross-linked XLPE material has higher heat resistance, aging resistance and mechanical strength, which can significantly improve the performance of the cable.

Then is the cabling process. 4 insulated wire cores are twisted according to a certain pitch to form a cable core. During the stranding process, it is necessary to ensure that the positions of the insulated wire cores are uniform to avoid damaging the insulation layer due to mutual friction. In order to ensure the roundness and stability of the cable core, filling materials, usually polypropylene ropes, may be added in the middle of the cable core. The outside of the filled cable core will be wrapped with a layer of non-woven fabric or film to enhance the integrity of the cable core.

Finally, the extrusion process of the sheath (if there is a sheath). For cables that need a sheath, a layer of sheath material, such as polyvinyl chloride (PVC), will be extruded and coated on the outside of the cabled core. The sheath can further protect the cable from the external environment, such as mechanical damage, chemical corrosion, etc. The process of extruding the sheath is similar to that of extruding the insulation layer, and various parameters need to be strictly controlled to ensure the quality of the sheath.

During the entire production process, multiple quality inspections are also required, such as conductor resistance test, insulation layer voltage resistance test, thickness measurement, etc., to ensure that each process meets the quality standards. Only cables that have passed strict inspection can leave the factory for sale.

The packaging design of 4X1c copper core XLPE insulated low-voltage power cable fully considers the product protection, transportation and storage needs, aiming to ensure that the cable is in good condition when it reaches the user.

For coiled cables, wooden or iron reels are usually used for packaging. Wooden reels have relatively low cost and light weight, and are suitable for short-distance transportation and general storage environments. The material of the wooden reel is mostly pine or fir, which has certain strength and toughness and can bear the weight of the cable. Iron reels have higher strength and durability, and are suitable for long-distance transportation and packaging of large cables. The surface of the iron reel is usually treated with anti-rust to resist the erosion of humid environment and prolong the service life.

The cable is neatly wound on the reel, and the tension must be uniform during winding to avoid loosening or twisting of the cable. After winding, a layer of plastic film will be wrapped around the outside of the cable. The plastic film has good moisture-proof and dust-proof performance, which can prevent the cable from being eroded by moisture and dust during transportation and storage. For some special specifications or cables that need to be stored for a long time, a layer of linen or woven bag will be wrapped outside the plastic film to enhance the protection effect and prevent the cable from being collided and rubbed.

In the prominent position of the package, relevant product information will be clearly marked, such as product name, model specification, length, rated voltage, production date, manufacturer, implementation standard, etc. This information helps users check and identify when receiving and using the cable, and also facilitates product traceability and management. In addition, some warning signs will be printed on the package, such as "Do not press heavily", "Moisture-proof", "Handle with care", etc., to remind transportation and storage personnel to pay attention to correct operation methods and avoid damaging the cable due to improper operation.

For small batches of cables, carton packaging can also be used. The material of the carton is corrugated paper, which has certain compressive strength. Buffering materials such as foam boards and bubble films will be placed inside the carton to reduce the shaking and collision of the cables during transportation. Carton packaging is relatively light, easy to carry and load/unload, and suitable for transportation of small-sized and short-length cables.

The transportation of 4X1c copper core XLPE insulated low-voltage power cable needs to follow strict norms and requirements to ensure the safety and integrity of the cable.

In terms of transportation methods, according to different transportation distances, quantities and customer needs, road transportation, railway transportation or waterway transportation can be adopted. Road transportation has high flexibility and can realize door-to-door service, which is suitable for medium and short-distance transportation and transportation of small batches of cables. The transport vehicle is usually a truck, and the carriage needs to be kept clean and dry to avoid contamination and moisture of the cable. Railway transportation has large capacity, low cost and good stability, and is suitable for long-distance transportation and transportation of large batches of cables. During railway transportation, cables are usually placed in containers or railway freight cars and need to be properly fixed to prevent movement and collision during transportation. Waterway transportation is suitable for cross-regional and transnational transportation, which can transport a large number of cables, but the transportation time is relatively long. During waterway transportation, cables need to be stored in the cabin to avoid erosion by sea water and the impact of humid environment.

During transportation, the loading and unloading of cables need to be careful. When using cranes and other equipment, avoid damaging the cable packaging. The stacking of cables in transport vehicles or containers should be reasonable to avoid excessive stacking leading to deformation of the bottom cables. Cables of different specifications and models should be stacked separately with obvious signs for easy counting and management.

During transportation, attention should be paid to protecting the cables from harsh environments. In high temperature in summer, avoid long-term exposure of the cable to sunlight to prevent the cable insulation layer from aging due to high temperature; in low temperature in winter, prevent the cable from becoming brittle due to freezing, which affects its flexibility. In case of rain and snow, ensure the tightness of the transport vehicle or container to prevent rainwater from entering and damaging the cable. At the same time, avoid contact between the cable and sharp objects to prevent 划破 the insulation layer and sheath of the cable.

During transportation, drivers should abide by traffic rules, maintain stable driving, avoid sudden braking, sharp turns and other operations, and reduce the impact force on the cables. Transport vehicles should be regularly inspected and maintained to ensure their good performance, and avoid affecting the transportation progress and cable safety due to vehicle failures.
