The Na series 0.6/1kv aluminum XLPE power cables are constructed using high-quality materials, and their design is optimized for performance and durability in various environments.

The conductor is made of high-purity aluminum with a purity of 99.5% or higher. This high purity ensures good electrical conductivity, which is essential for efficient power transmission. Although aluminum has a lower conductivity compared to copper, its significantly lower cost makes it an economical choice for low-voltage power cables. The Aluminum Conductor undergoes a special annealing process, which enhances its ductility and Flexibility, making it easier to handle during installation. It also improves the conductor's resistance to fatigue, ensuring a longer service life. Additionally, the aluminum surface is treated with an anti-oxidation coating, which protects it from corrosion caused by moisture, oxygen, and other environmental factors. This coating ensures that the conductor maintains its electrical and mechanical properties over time.

The insulation layer is composed of XLPE (cross-linked polyethylene), a material known for its excellent electrical and mechanical properties. XLPE is formed by cross-linking polyethylene molecules, which creates a three-dimensional network structure. This structure gives XLPE superior thermal resistance compared to traditional polyethylene, allowing the cable to operate at higher temperatures. It can withstand long-term operating temperatures of up to 90℃ and short-term overload temperatures of 130℃, making it suitable for applications where power demand fluctuates. XLPE also has a high insulation resistance, which minimizes leakage current and ensures efficient power transmission. Its excellent resistance to corona discharge and electrical breakdown enhances the cable's safety and reliability. Furthermore, XLPE is resistant to chemicals, oils, and moisture, making it suitable for use in harsh environments.

The cable may also feature an outer sheath, typically made of PVC (polyvinyl chloride) or PE (polyethylene), depending on the specific model and application requirements. The outer sheath provides additional protection to the cable, shielding it from mechanical damage, abrasion, and environmental factors such as sunlight, moisture, and chemicals. PVC Sheaths offer good mechanical strength and flame retardancy, making them suitable for indoor and outdoor applications where fire safety is a concern. PE sheaths, on the other hand, have better flexibility and resistance to low temperatures, making them ideal for cold environments or applications where the cable needs to be bent frequently.

In terms of style, all cables in the Na series are single-core, which simplifies installation in tight spaces and allows for easier handling. The single-core design also reduces the risk of electromagnetic interference, which is beneficial in sensitive electrical systems. The cables have a round cross-section, which ensures uniform distribution of stress during installation and operation, reducing the likelihood of damage. The outer surface of the sheath is smooth, which minimizes friction during pulling, making installation more efficient. The sheath is usually colored black, which provides UV resistance, protecting the cable from degradation caused by exposure to sunlight, making it suitable for outdoor use.

The production of Na series 0.6/1kv aluminum XLPE power cables involves a series of precise and controlled processes to ensure the highest quality standards are met.

The first step is the production of the aluminum conductor. High-purity aluminum ingots are melted and cast into continuous rods. These rods are then subjected to a drawing process, where they are pulled through a series of dies to reduce their diameter to the required size for the conductor. The drawing process is carefully controlled to ensure the conductor has a uniform diameter and smooth surface. After drawing, the conductor undergoes an annealing process. It is heated to a specific temperature (typically between 300℃ and 500℃) in a controlled atmosphere (often nitrogen) to relieve internal stresses, improve ductility, and enhance conductivity. The annealed conductor is then inspected for dimensional accuracy and surface quality.

Next, the insulation extrusion process takes place. The aluminum conductor is fed into an extrusion line, where XLPE insulation is extruded around it. The XLPE material is first dried to remove any moisture, which could affect the insulation properties. The dried material is then fed into an extruder, where it is melted and forced through a die that shapes the insulation around the conductor. The extrusion process is maintained at precise temperatures (usually between 120℃ and 180℃) to ensure proper melting and adhesion of the XLPE to the conductor. After extrusion, the Insulated Conductor enters a cross-linking tube, where it is exposed to high temperature and pressure (using steam or nitrogen) to cross-link the polyethylene molecules. This cross-linking process is critical as it transforms the linear polyethylene into a three-dimensional network structure, enhancing the insulation's thermal and mechanical properties.

Once the insulation is cross-linked, the cable undergoes a cooling process to solidify the insulation. It is then passed through a series of sizing and cooling rollers to ensure the insulation has the correct thickness and dimensions. The Insulated Cable is inspected for insulation thickness, eccentricity (to ensure uniform insulation around the conductor), and surface defects.

If the cable is designed with an outer sheath, the next step is sheath extrusion. The insulated conductor is fed into another extrusion line, where the outer sheath material (PVC or PE) is extruded over the insulation. Similar to the insulation extrusion process, the sheath material is dried, melted, and extruded through a die. The extrusion parameters are controlled to ensure proper adhesion between the sheath and the insulation, as well as uniform thickness and surface quality. After extrusion, the cable is cooled to solidify the sheath.

Following the extrusion processes, the cable undergoes a series of electrical tests to verify its performance. These tests include the insulation resistance test, which measures the resistance of the insulation to current leakage; the withstand voltage test, which subjects the cable to a higher-than-rated voltage for a specified period to ensure it can withstand electrical stress without breakdown; and the partial discharge test, which detects any partial discharges within the insulation, which could indicate potential defects.

Mechanical tests are also performed, including tensile strength and elongation tests on the insulation and sheath materials to ensure they meet the required mechanical properties. The cable is also checked for dimensional accuracy, including conductor size, insulation thickness, and outer diameter.

Finally, the cables are cut to the required lengths, spooled onto reels or coils, and packaged for shipping. Each reel or coil is labeled with information such as the cable model, specification, length, production date, and batch number for traceability.

Throughout the production process, strict quality control measures are implemented. Raw materials are inspected upon arrival to ensure they meet the required specifications. In-process inspections are conducted at each stage of production to identify and address any issues promptly. Finished cables are sampled and tested to ensure they comply with relevant standards and specifications, such as IEC (International Electrotechnical Commission) or national standards.

The packaging of Na series 0.6/1kv aluminum XLPE power cables is designed to protect the cables during storage, transportation, and handling, ensuring they reach the customer in pristine condition.

For large-length cables (typically 500 meters or more), wooden or steel reels are used. Wooden reels are made from high-quality, durable timber that is resistant to warping and damage. They are constructed with sturdy flanges to prevent the cable from slipping off during transportation. Steel reels, on the other hand, are used for heavier cables or when greater durability is required. They are made from thick steel plates and are welded for strength, making them suitable for repeated use and long-distance transportation. The cable is tightly and evenly wound onto the reel to prevent tangling and damage. A layer of moisture-resistant plastic film is wrapped around the cable before winding to protect it from moisture and dust. The reels are then secured with steel bands or straps to ensure the cable remains in place during transportation.

For shorter lengths (typically less than 500 meters), the cables are supplied in coils. The coils are formed by winding the cable into a circular shape with a diameter suitable for handling and storage. The coils are wrapped with plastic film to protect against moisture and dirt and are then secured with plastic straps to maintain their shape. These coils are often placed in cardboard boxes or woven bags for additional protection. The boxes or bags are labeled with the same information as the reels, including the cable model, specification, length, and batch number.

All packaging includes clear and durable labels that provide essential information about the cable. This information includes the product name, model number, conductor cross-sectional area, rated voltage, length, production date, batch number, and the manufacturer's name and logo. For international shipments, labels may also include bilingual information (e.g., English and the local language) to facilitate customs clearance and handling.

Special attention is given to the packaging of cables intended for export. Wooden reels used for export are treated to meet international phytosanitary standards, such as ISPM 15, which requires heat treatment or fumigation to prevent the spread of pests. This ensures compliance with the import regulations of various countries.

The transportation of Na series 0.6/1kv aluminum XLPE power cables is carefully planned and executed to ensure their safe and timely delivery.

Before transportation, the cables are inspected to ensure the packaging is intact and secure. Any damaged packaging is repaired or replaced to prevent damage to the cables during transit. For reel-mounted cables, the reels are checked to ensure they are properly secured and that the cable is tightly wound. Coils and boxed cables are inspected to ensure they are properly strapped and protected.

The choice of transportation mode depends on the distance, quantity, and destination. For short distances, road transportation using trucks is commonly used. The trucks are equipped with appropriate securing devices, such as winches and straps, to secure the cable reels or coils during transit. For longer distances or international shipments, rail or sea transportation may be used. Rail transportation is suitable for large quantities of cables, offering a stable and cost-effective option. Sea transportation is used for international shipments, with the cables loaded into containers. The containers are secured to prevent movement during the voyage, and the cables are protected from moisture and extreme temperatures.

During transportation, the cables are handled with care to avoid mechanical damage. Reel-mounted cables are transported either horizontally or vertically, depending on their size and weight. Horizontal transportation is preferred for larger reels, as it provides better stability. When transporting vertically, the reels are secured with additional supports to prevent tipping. Coils and boxed cables are stacked carefully to avoid crushing, with heavier items placed at the bottom.

Temperature control is important during transportation, especially for long-distance shipments. Extreme temperatures can affect the properties of the cable materials. In hot weather, cables are protected from direct sunlight using tarpaulins or covers to prevent overheating. In cold weather, measures are taken to prevent the cables from freezing, which could make the sheath brittle and prone to cracking.

Moisture protection is also crucial. During transportation in rainy or humid conditions, the cables are covered with waterproof tarpaulins to prevent water from entering the packaging. This protects the insulation and conductor from moisture damage, which could compromise the cable's performance.

Transportation personnel are trained in the proper handling of cable products. They are aware of the importance of avoiding sharp impacts, excessive bending, and exposure to harmful substances. During loading and unloading, appropriate equipment such as cranes, forklifts, and winches is used to handle heavy

reels and coils, minimizing the risk of damage. They follow strict loading and unloading procedures to ensure the cables are handled safely and efficiently.
