In terms of cross-sectional specifications, this cable covers 120mm², 150mm², 185mm², and 240mm². These different cross-sectional areas correspond to different current-carrying capacities, allowing the cable to adapt to various power transmission demands. Specifically, the 120mm² cable has a rated current-carrying capacity of approximately 270-320A, which is suitable for power transmission in small to medium-sized industrial parks and some large building distribution systems. The 150mm² cable can carry a current of about 310-370A, making it applicable to larger industrial plants and medium-sized power distribution networks. The 185mm² cable has a current-carrying capacity of around 350-420A, which is suitable for main
Power Lines in large industrial parks and key urban areas. The 240mm² cable, with a current-carrying capacity of approximately 420-500A, is capable of undertaking large-capacity power transmission tasks such as substation outgoing lines and urban power grid trunk lines.
The rated voltage of this cable is designed for medium and high voltage levels, typically ranging from 10kV to 35kV. This voltage range enables it to be widely used in power transmission systems between cities, power supply lines of industrial parks, and connection lines of substations, meeting the needs of long-distance and large-capacity power transmission.
In addition, the insulation thickness of the cable varies according to different cross-sectional specifications. For the 120mm² cable, the insulation thickness is about 2.5mm; for 150mm², it is around 2.8mm; 185mm² has an insulation thickness of approximately 3.0mm; and 240mm² has an insulation thickness of about 3.4mm. The appropriate insulation thickness ensures that the cable can withstand the corresponding voltage levels and provides effective insulation protection. The thickness of the aluminum wire armouring layer is generally 0.5-0.8mm, and the braiding density is about 80%, which can effectively resist external mechanical forces. The thickness of the inner and outer
PVC Sheaths is about 1.0-1.5mm, providing good buffering and protection.
Characteristic Applications
The 1/C Cu/XLPE/PVC/Awa/PVC single core aluminum wire armoured cable, with its unique structure and excellent performance, has a wide range of characteristic applications in various fields.
In industrial parks, the 120mm² to 185mm² cables are widely used in main power lines. Industrial parks gather a large number of factories and enterprises with diverse power demands. These cables can stably transmit electricity from the park's substation to each factory, ensuring the normal operation of production equipment. For example, in a machinery manufacturing park, the 150mm² cable is used to connect the central substation to the workshops, providing sufficient power for stamping machines, lathes, and other large equipment.
Large building distribution systems also rely on these cables. Buildings such as high-rise commercial complexes, large shopping malls, and hospitals have high requirements for power supply stability. The 120mm² to 185mm² cables can meet the power needs of multiple floors and various facilities. In a high-rise commercial complex, the 185mm² cable is used as the main distribution line in the basement, distributing power to elevators, air conditioning systems, lighting, and other equipment, ensuring the normal operation of the entire building.
The 240mm² cable is particularly suitable for large-capacity power transmission scenarios such as substation outgoing lines and urban power grid branches. Substations are important nodes in the power grid, responsible for transforming and distributing electricity. The 240mm² cable can transmit high-voltage electricity from the substation to the urban power grid, ensuring that electricity is supplied to thousands of households. In urban power grid construction, the 240mm² cable is used in branch lines, connecting the main grid to residential areas and commercial districts, improving the reliability and stability of power supply.
The single-core design of the cable is an important feature that makes it suitable for high-voltage scenarios. In high-voltage power transmission,
Multi-Core cables are prone to eddy current losses, which waste energy and affect the efficiency of power transmission. The single-core design avoids this problem, reducing energy loss and improving the efficiency of power transmission. Therefore, it is widely used in high-voltage transmission lines such as 10kV and 35kV.
In terms of installation environments, the cable is suitable for underground direct burial, tunnel laying, and industrial plants. Underground direct burial is a common installation method. The aluminum wire armouring layer and PVC outer sheath can protect the cable from soil pressure, corrosion, and damage from underground organisms. In tunnel laying, the cable is not affected by weather factors such as wind and rain, and the armouring layer can resist collisions from construction equipment and other objects. In industrial plants with harsh environments, such as chemical plants and steel mills, the cable's corrosion resistance and high-temperature resistance ensure its stable operation despite oil pollution, dust, and high temperatures.
Material Styles
The material selection and style design of the 1/C Cu/XLPE/PVC/Awa/PVC single core aluminum wire armoured cable are crucial to its performance, and each layer of material has unique functions.
The conductor is made of high-purity electrolytic copper with a purity of 99.9%, which has excellent electrical conductivity. This high-purity copper ensures low resistance during current transmission, reducing energy loss and improving power transmission efficiency. Compared with other copper materials, high-purity electrolytic copper has better ductility and toughness, making it easier to process into wires of various specifications and not easy to break during installation and use.
The insulation layer is made of cross-linked polyethylene (XLPE), which has excellent performance. After special cross-linking treatment, XLPE has a wide temperature resistance range, from -40℃ to 105℃, enabling it to work normally in extremely cold and high-temperature environments. It also has strong aging resistance, and its performance remains stable even after long-term use, extending the service life of the cable. In addition, XLPE has high insulation resistance (≥1000MΩ), which can effectively prevent current leakage and ensure the safety of power transmission. It also has good chemical corrosion resistance, resisting erosion from acids, alkalis, and other chemicals.
The inner sheath is made of polyvinyl chloride (PVC), which is located between the XLPE insulation layer and the aluminum wire armouring layer. Its main function is to buffer and isolate, protecting the insulation layer from damage during the braiding of the armouring layer. PVC has good
Flexibility and wear resistance, which can reduce friction between the insulation layer and the armouring layer, ensuring the integrity of the insulation layer.
The armouring layer adopts an aluminum wire (Awa) braided structure. Aluminum wire has the characteristics of light weight and high strength, which not only reduces the overall weight of the cable, making it easier to transport and install, but also provides good mechanical protection. The braided structure makes the armouring layer have good flexibility, adapting to various laying environments. The aluminum wire is treated with anti-corrosion, which can resist corrosion from moisture, oxygen, and other substances in the environment, ensuring the long-term effectiveness of the armouring layer.
The outer sheath is also made of PVC, which is the outermost layer of the cable. It further enhances the cable's weather resistance, resisting the erosion of ultraviolet rays, rain, snow, and other natural factors, ensuring the cable's performance stability in outdoor environments. At the same time, the outer sheath has good mechanical protection, resisting external impact, extrusion, and wear, protecting the internal structure of the cable.
In terms of style, the cable is a single-core cylindrical structure with a smooth surface. The color of the outer sheath is usually black, which has good heat resistance and UV resistance. The overall structure is compact, and the flexibility is moderate, which is convenient for bending and laying in various environments.
Production Process
The production process of the 1/C Cu/XLPE/PVC/Awa/PVC single core aluminum wire armoured cable is complex and precise, with strict control over each process to ensure product quality.
The first step is conductor manufacturing. High-purity electrolytic copper rods are used as raw materials and undergo wire drawing processing. The copper rods are drawn into
Copper Wires of the required diameter through a wire drawing machine. During the wire drawing process, the speed and temperature of the wire drawing are strictly controlled to ensure the uniformity of the copper wire diameter and the smoothness of the surface. After wire drawing, the copper wires are annealed. Annealing is carried out in a controlled atmosphere furnace, heating the copper wires to a certain temperature and then cooling them slowly. This process improves the ductility and conductivity of the copper wires, making them easier to process in subsequent processes.
Next is the extrusion of the XLPE insulation layer. The annealed
Copper Conductor is sent to the insulation extrusion machine. The XLPE material is heated and melted in the extruder, and then evenly coated on the surface of the conductor through a die. During the extrusion process, parameters such as extrusion temperature, speed, and pressure are strictly controlled to ensure that the insulation layer has uniform thickness, no bubbles, no impurities, and good adhesion to the conductor. After extrusion, the
Insulated Wire core enters the cross-linking tube for cross-linking treatment. The cross-linking process is usually carried out by steam or nitrogen, which makes the linear molecular structure of XLPE form a three-dimensional network structure, improving its mechanical properties, heat resistance, and insulation performance.
After the insulation layer is formed, the inner PVC sheath is extruded. The insulated wire core is sent to the sheath extrusion machine, and the PVC material is heated and melted, then extruded onto the surface of the insulation layer. The inner sheath extrusion process also requires strict control of parameters to ensure uniform thickness and good adhesion to the insulation layer. The inner sheath plays a role in buffering and protecting the insulation layer, preparing for the subsequent armouring process.
Then comes the armouring process. The cable core with the inner sheath is sent to the armouring machine. The
Aluminum Wires are braided on the surface of the inner sheath according to a certain density and pitch. The braiding density is about 80%, ensuring that the armouring layer has good coverage and mechanical protection. During the braiding process, the tension of the aluminum wires is controlled to ensure the tightness and uniformity of the braiding. The braided aluminum wire armouring layer provides good mechanical protection for the cable, resisting external impact and extrusion.
Finally, the outer PVC sheath is extruded. The cable core with the armouring layer is sent to the outer sheath extrusion machine. The PVC material is melted and extruded onto the surface of the armouring layer, forming the outer sheath. The outer sheath extrusion process is similar to the inner sheath, with strict control of parameters to ensure uniform thickness and good adhesion. The outer sheath protects the armouring layer and the internal structure of the cable, enhancing the cable's weather resistance and mechanical properties.
After the production is completed, the cable undergoes a series of tests. These tests include conductor resistance test, insulation resistance test, withstand voltage test, mechanical performance test, etc. The conductor resistance test ensures that the conductivity of the conductor meets the standard; the insulation resistance test checks the insulation performance of the insulation layer; the withstand voltage test verifies the cable's ability to withstand rated voltage; the mechanical performance test tests the tensile strength, elongation at break, etc. of the cable. Only cables that pass all tests are allowed to leave the factory.

Packaging
The packaging of the 1/C Cu/XLPE/PVC/Awa/PVC single core aluminum wire armoured cable is designed to ensure the safety of the cable during transportation and storage, preventing damage from external factors.
The cable is wound on galvanized iron reels. The galvanized iron reels are made of high-quality steel and undergo galvanizing treatment, which has good corrosion resistance, ensuring that the reels do not rust during storage and transportation. The size of the iron reels is determined according to the length and cross-sectional specification of the cable. For example, 120mm² and 150mm² cables with a length of 500 meters are usually wound on iron reels with a diameter of 1.2 meters; 185mm² and 240mm² cables with a length of 500 meters are wound on iron reels with a diameter of 1.5 meters. This ensures that the cable is neatly wound and not easily distorted.
Before winding the cable on the iron reel, the surface of the cable is wrapped with moisture-proof kraft paper. The moisture-proof kraft paper has good water resistance, preventing moisture from entering the cable during storage and transportation, ensuring the insulation performance of the cable. The kraft paper is wrapped tightly, covering the entire surface of the cable.
After the cable is wound on the iron reel, the outer layer is wrapped with a layer of winding film. The winding film is made of high-strength polyethylene material, which has good tensile strength and adhesion. It tightly wraps the cable and the iron reel together, preventing the cable from loosening and falling off during transportation. At the same time, the winding film has good waterproof and dustproof properties, protecting the cable from rain, dust, and other contaminants.
In addition, labels are affixed to the iron reels, indicating the cable's model, specification, length, rated voltage, production date, batch number, and manufacturer information. These labels facilitate the identification and management of the cable during transportation, storage, and use.
