Aluminum Power Cables (10mm², 16mm², 25mm², 35mm², 240mm²) have rich and precise specification parameters, providing solid technical support for their power transmission in various outdoor scenarios.

Cross-sectional size is one of the core specification parameters of this series of cables, covering various types such as 10mm², 16mm², 25mm², 35mm², and 240mm². These sizes are determined through a large number of engineering practices and theoretical calculations, which can accurately match the power needs of different power equipment. The 10mm² cable has a relatively small diameter, which is more flexible in installation and suitable for power supply of small outdoor equipment with limited space; while the 240mm² cable has a larger diameter, which can carry larger current and meet the power transmission needs of large outdoor projects.

Current-carrying capacity is a key indicator to measure the power transmission capacity of cables, and the current-carrying capacity of cables with different cross-sectional sizes varies significantly. The current-carrying capacity of the 10mm² cable is about 50-60A, which is sufficient to meet the power needs of small outdoor equipment such as garden lighting and small water pumps. These equipment have relatively small power and stable and small power demand. The 16mm² cable has a current-carrying capacity of 65-80A, which can cope with the power consumption of outdoor billboards, monitoring equipment, etc. Although such equipment is not extremely powerful, it requires continuous and stable power supply to ensure normal operation. The 25mm² cable has a current-carrying capacity of 85-105A, which is often used for power transmission from outdoor distribution boxes to medium-sized equipment such as landscape fountains and small agricultural machinery. These equipment have moderate power but high requirements for the stability of power transmission. The 35mm² cable has a current-carrying capacity of 100-125A, which can provide sufficient power for larger outdoor equipment, such as some medium-sized agricultural irrigation equipment and temperature control systems in greenhouses. The 240mm² cable has a current-carrying capacity of up to 300-350A, which can be adapted to large outdoor projects such as substation outgoing lines and high-voltage transmission branches. These scenarios have a huge demand for electricity and long transmission distances, requiring cables to have strong current-carrying capacity.

This series of cables all adopt a four-core structure. This design is to meet the needs of three-phase four-wire power supply, ensuring the stability and safety of the power supply system. One of the cores is specially used as a Grounding Wire. When the equipment has faults such as electric leakage or short circuit, it can quickly conduct the current to the ground, avoiding electric shock accidents and providing an important guarantee for outdoor electricity safety. The arrangement of the four cores is optimized to ensure the compactness of the cable and facilitate installation and maintenance.

In addition, the insulation resistance of the cable is also an important specification parameter. Under standard conditions, the insulation resistance of this series of cables can reach more than the specified value, ensuring that the cable has good insulation performance, effectively preventing current leakage, reducing power loss, and avoiding safety accidents caused by poor insulation. The voltage withstand performance of the cable has also been strictly tested, which can withstand a certain voltage impact, operate stably within the normal working voltage range, and adapt to possible voltage fluctuations in the outdoor power grid.

Aluminum Power Cables (10mm², 16mm², 25mm², 35mm², 240mm²) have irreplaceable characteristic applications in many outdoor scenarios due to their various specifications and excellent performance.

In the field of municipal engineering, this series of cables plays an important role. 10mm² and 16mm² cables are widely used in the street lamp power supply system on both sides of the road. Road street lamps are widely distributed, and have high requirements for cable laying. These two specifications of cables have small diameters, which are more convenient to lay, and their current-carrying capacity can meet the power needs of street lamps. At the same time, they are also suitable for traffic signal systems. Traffic signals need stable power supply to ensure normal operation and road traffic safety and order. The stability and reliability of these two cables can meet their requirements.

25mm² and 35mm² cables are commonly used in landscape lighting and background music systems in public areas such as parks and squares. Landscape lighting is usually composed of multiple lamps, distributed in various corners of parks and squares, requiring cables to have a certain current-carrying capacity and good weather resistance. 25mm² and 35mm² cables can just meet these needs, ensuring that landscape lamps light up normally at night and create a beautiful night environment. The power of background music system equipment is moderate, and these two specifications of cables can provide stable power for it, allowing people to enjoy comfortable music during leisure and entertainment. In addition, the power transmission of outdoor charging piles is also inseparable from 25mm² and 35mm² cables. With the popularization of new energy vehicles, the number of outdoor charging piles is increasing, and the requirements for power transmission are also increasing. These two cables can ensure that charging piles charge vehicles quickly and safely.

The agricultural field is another important application scenario for this series of cables. 35mm² cables can be connected to field irrigation equipment. Agricultural irrigation equipment needs continuous power to drive devices such as water pumps to ensure the growth needs of crops. The current-carrying capacity of 35mm² cables can meet their power requirements, and they have strong weather resistance and can adapt to the complex environment in the field. In greenhouses, the temperature control system is highly dependent on electricity. 35mm² cables can provide stable power for temperature control equipment, ensuring that environmental parameters such as temperature and humidity in the greenhouse remain within the range suitable for crop growth. 240mm² cables provide power support for large agricultural transformers and power equipment in farms. Large agricultural transformers are important hubs of the agricultural power system and require strong power transmission capacity. Power equipment in farms, such as feed processors and ventilation equipment, have large power. The high current-carrying capacity of 240mm² cables can meet the power needs of these equipment, ensuring the smooth progress of agricultural production.

In outdoor temporary construction, this series of cables also performs well. Small 规格 cables such as 10mm² and 16mm² can be used as temporary transmission lines to supply power to small construction tools such as hand drills and cutting machines; 25mm² and 35mm² cables can provide power to medium-sized construction equipment such as mixers and electric welders; 240mm² cables can meet the power needs of large construction machinery such as excavators and cranes. The portability and durability of these cables enable them to be quickly deployed and used in temporary construction, effectively improving construction efficiency and ensuring that construction projects are completed on time.

Aluminum Power Cables (10mm², 16mm², 25mm², 35mm², 240mm²) fully consider the special environment of outdoor use in material selection and style design, showing excellent performance and practicality.

The conductor is made of high-purity aluminum material with a purity of more than 99.5%. High-purity aluminum not only ensures good conductivity, enabling it to effectively reduce energy loss during power transmission and improve transmission efficiency, but also, compared with copper, aluminum has a smaller density, which greatly reduces the weight of the cable. This feature is particularly important in Outdoor Cable erection, reducing the load pressure during erection, lowering installation difficulty and cost, and also reducing the load requirements on the erection 支架. In addition, aluminum has strong corrosion resistance, and is not easy to be corroded and damaged in humid and dusty outdoor environments, and can maintain stable performance for a long time, extending the service life of the cable.

The outer sheath is made of PVC (polyvinyl chloride) material, which is an important guarantee for the cable's protective performance. The PVC Sheath has excellent weather resistance and can maintain stable performance in the temperature range of -20℃ to 60℃. It can work normally in both cold winters and hot summers, without being affected by extreme temperatures. Its UV aging resistance is also very excellent. When exposed to sunlight for a long time, it will not easily crack or harden, ensuring the effective protection of the inner conductor by the sheath. At the same time, PVC material has good waterproof performance, which can effectively block water such as rain and dew from entering the cable, avoiding the conductor from getting damp and affecting conductivity or causing short-circuit faults. Moreover, PVC also has acid and alkali corrosion resistance, and can adapt to outdoor possible acid and alkali environments, such as near chemical plants and farmland irrigation areas, protecting the cable from chemical erosion.

In terms of style, this series of cables adopts a four-core tightly stranded structure design. This structure not only enhances the Flexibility of the cable, enabling it to be flexibly bent and laid in complex outdoor terrain, such as bypassing obstacles and passing through pipes, reducing obstacles in the installation process, but also the stranding method makes the four cores an integral whole, improving the mechanical strength of the cable, enhancing its tensile and impact resistance, and better resisting external forces during outdoor construction or use.

The appearance color of the cable is usually dark colors such as black or gray. This color choice helps reduce sunlight reflection, lowering the temperature rise of the cable in sunlight, and at the same time, it can better integrate with the outdoor environment, reducing visual 突兀感. The surface of the cable is printed with clear marks, including product model, cross-sectional size, rated voltage, manufacturer and other information. These marks not only facilitate users to identify and select suitable cables, but also provide convenience for cable installation, maintenance and management.

The production process of aluminum power cables (10mm², 16mm², 25mm², 35mm², 240mm²) is complex and rigorous, and each link is strictly controlled to ensure that the product quality meets the high standards of outdoor use.

Aluminum ingot smelting is the first step in production. High-purity aluminum ingots are selected as raw materials and put into a smelting furnace for heating and smelting. During the smelting process, it is necessary to accurately control the temperature, generally around 700℃, and at the same time, carry out impurity removal treatment on the aluminum liquid to remove impurities and gases in it to ensure the purity of the aluminum liquid. The impurity removal treatment usually uses a refining agent. By stirring, the refining agent is fully contacted with the aluminum liquid, adsorbing impurities and floating to the surface to be removed. The smelted aluminum liquid is left to stand, and then cast into aluminum rods through casting equipment. The quality of the aluminum rods directly affects the performance of subsequent conductors, so it is necessary to strictly control the casting speed and cooling method to ensure that the structure of the aluminum rods is uniform and dense.

Next is the aluminum rod wire drawing process. The aluminum rod is drawn into Aluminum Wires of the required diameter through a wire drawing machine. During the wire drawing process, the aluminum rod passes through a series of dies of different specifications and is gradually drawn to the target diameter. The wire drawing speed, die lubrication and cooling conditions need to be accurately controlled to ensure that the Aluminum Wire has a uniform diameter, smooth surface, and good mechanical properties and conductivity. For cables of different cross-sectional sizes, the required diameter and number of aluminum wires are different. For example, 10mm² cables may be stranded by multiple thinner aluminum wires, while 240mm² cables require more or thicker aluminum wires.

Aluminum wire stranding is a key step in forming conductors. According to the cross-sectional size requirements of the cable, multiple aluminum wires are stranded together in a certain stranding way to form the required conductor. There are regular stranding, bunch stranding and other stranding methods. Different stranding methods will affect the flexibility and filling coefficient of the conductor. During the stranding process, it is necessary to ensure that the tension of the aluminum wires is uniform and the stranding pitch is consistent to ensure the roundness and structural stability of the conductor, and avoid conductor loosening or uneven stress in subsequent processes.

After the conductor is formed, the insulation layer is extruded. The insulating material (usually polyethylene or cross-linked polyethylene) is added to the extruder, heated and melted, and then uniformly coated on the surface of the conductor through a die to form an insulation layer. The thickness of the insulation layer is determined according to the voltage level and use environment of the cable. It is necessary to accurately control the extrusion temperature, pressure and speed to ensure that the insulation layer has a uniform thickness, smooth surface, and is closely combined with the conductor, without bubbles, impurities and other defects. The quality of the insulation layer is directly related to the insulation performance of the cable, so it must undergo strict testing.

Subsequently, the cabling process is carried out. Four conductors with insulation layers (one of which is a grounding wire) are cabled according to a certain stranding direction and pitch. During the cabling process, in order to ensure the roundness and structural stability of the cable, some filling materials, such as polypropylene ropes, are filled between the conductors. The selection of filling materials should consider their weather resistance and chemical stability to adapt to the outdoor environment. After cabling, it is also necessary to wrap a layer of wrapping tape on the outside to fix the cabled structure and prevent the conductors from loosening.

Finally, the sheath is extruded. PVC material is added to the extruder, heated and melted, and then coated on the outside of the cabled core through a die to form the outer sheath. The process requirements for sheath extrusion are similar to those for the insulation layer. It is necessary to strictly control various parameters to ensure that the sheath has a uniform thickness, flat surface, is closely combined with the core, and has good sealing performance. After the sheath extrusion is completed, the cable also needs to undergo cooling, traction and other treatments to shape it.

During the entire production process, multiple quality inspection procedures are required. From the inspection of raw materials, to the inspection of semi-finished products in each process, to the performance testing of finished cables, such as conductor resistance, insulation resistance, voltage withstand performance, mechanical performance, etc., to ensure that each batch of cables meets relevant standards and technical requirements. Only cables that pass strict inspection can leave the factory and be put into use.

The packaging design of aluminum power cables (10mm², 16mm², 25mm², 35mm², 240mm²) fully considers the characteristics of the product and the needs of transportation and storage, aiming to protect the cable from damage during the entire circulation process and ensure the quality and performance of the product.

For coiled cables, wooden cable reels are usually used for packaging. Wooden cable reels have the characteristics of high strength and good stability, and can provide solid support for the cables. The size of the cable reel is designed according to the length and cross-sectional size of the cable. For example, small 规格 10mm² and 16mm² cables can use cable reels with smaller diameters, while large 规格 240mm² cables require cable reels with larger diameters to ensure that the cables can be neatly wound on them, avoiding twisting, folding or loosening. When winding the cable, it is necessary to control the winding tension to make the cable arranged tightly, reducing shaking and friction during transportation and preventing the cable sheath from being worn.

The two sides of the cable reel are equipped with solid baffles, and the height of the baffles is higher than the winding height of the cable to prevent the cable from slipping during transportation and handling. The thickness and material of the baffles are strictly selected to ensure that they have sufficient strength to withstand the weight of the cable and the impact force during transportation. Metal hooks or holes are usually installed on the baffles to facilitate handling with forklifts, cranes and other equipment, improving handling efficiency and avoiding damage to the cable during handling.

A detailed label is pasted on the side of the cable reel, which clearly indicates the product name, model specification (such as 10mm², 16mm², etc.), length, rated voltage, production batch number, production date, implementation standard, manufacturer name and contact information, etc. This information not only facilitates users to identify and accept the product, but also provides convenience for product traceability and quality tracking. For exported cables, the information on the label also needs to be translated into the corresponding foreign language to meet the requirements of the international market.

In order to prevent the cable from getting damp and contaminated during storage and transportation, the outer layer of the cable is wrapped with a moisture-proof and dust-proof plastic film. The plastic film should be closely attached to the surface of the cable without gaps, which can effectively block moisture, dust, impurities, etc. from entering the cable, protecting the insulation layer and conductors of the cable from damage. For cable reels with long length and heavy weight, steel strips are used to firmly fix the cable on the cable reel. The tightening force of the steel strips should be moderate, which should ensure that the cable does not loosen and not excessively squeeze the cable, so as not to damage the sheath and insulation layer of the cable.

During storage, packaged cables should be stored in a dry, ventilated, dark warehouse away from heat sources and corrosive substances. The cable reel should be placed on a flat ground and padded with wooden blocks to keep a certain distance between the cable reel and the ground, preventing the cable reel from getting damp due to direct contact with the ground. At the same time, it is necessary to avoid stacking heavy objects on the cable reel to prevent the cable from being crushed and affecting its performance.

The transportation process of aluminum power cables (10mm², 16mm², 25mm², 35mm², 240mm²) needs to strictly follow relevant regulations and operating procedures to ensure the safety and integrity of the cable and avoid product damage due to improper transportation.

Before transportation, a comprehensive inspection of the cable packaging is required. Carefully check whether the cable reel is firm, whether the baffle is intact, whether the cable is wound neatly and tightly, whether the label is clear and complete, and whether the plastic film is well sealed. If any damage or looseness is found in the packaging, it should be repaired or repackaged in a timely manner until it meets the transportation requirements. For cables of different specifications, appropriate transportation tools and loading and unloading equipment should be selected according to their weight and size to ensure the safety of the transportation process.
