In addition, the insulation resistance of the cable is not less than 1000MΩ, which is far higher than the insulation resistance standard of general cables, effectively preventing electric leakage and ensuring the safety of power transmission. It can work stably for a long time in a 90°C humid environment, with excellent temperature resistance. At the same time, the bending radius of the cable is not less than 8 times the outer diameter. This parameter ensures that the cable can be flexibly bent during wiring, adapting to various complex installation environments and reducing construction difficulty.

XLPE copper cables, with their excellent performance, have unique and important uses in many scenarios, especially in humid environments.

In the industrial field, this cable can be widely used in humid workshops of factories. For example, in food processing workshops, due to the frequent need for cleaning operations, the environment is relatively humid. XLPE copper cables can withstand humid environments and a temperature of 90°C, providing stable power support for mixing equipment, packaging machinery, etc. in the workshop, ensuring the continuous progress of production. In sewage treatment plants, various water pumps, aeration equipment, etc. are in humid or even water environments for a long time. The moisture resistance and chemical corrosion resistance of XLPE copper cables make them an ideal power supply choice for these equipment, ensuring the smooth development of sewage treatment processes.

In the commercial field, underground parking lots of large shopping malls are common places for XLPE copper cables. The environment of underground parking lots is humid, and there are frequent vehicles coming and going, which have high requirements for the safety and durability of cables. This cable can provide reliable power for the lighting systems, ventilation equipment, charging piles, etc. in the parking lot, ensuring the normal operation of the parking lot. The humidity in swimming pools is extremely high. The power supply of pool water circulation systems, heating equipment, etc. is inseparable from XLPE copper cables. It can work stably in humid environments, ensuring the normal operation of various facilities in the swimming pool.

In terms of municipal engineering, in Underground Cable laying scenarios, cables are in underground humid environments for a long time and may be eroded by chemical substances in the soil. The moisture resistance and chemical corrosion resistance of XLPE copper cables enable them to operate stably for a long time in this environment, providing guarantee for urban power transmission. In the street lamp power supply system, street lamps are exposed to the outdoors all year round, experiencing wind and rain, and the environment is humid and changeable. XLPE copper cables can adapt to this environment, ensuring the normal lighting of street lamps and the safety of urban roads at night.

In addition, in greenhouses in the agricultural field, due to the need for frequent irrigation, the environment is relatively humid. The power supply of temperature control equipment, irrigation systems, etc. in the greenhouses can use XLPE copper cables to ensure the smooth progress of agricultural production. In some coastal facilities of marine engineering, such as crane equipment and lighthouses at docks, the environment is humid with a certain amount of salt spray. The weather resistance and corrosion resistance of XLPE copper cables enable them to work reliably in such environments.

XLPE copper cables fully combine the needs of their application scenarios in material selection and style design, taking into account performance, safety and practicality.

The conductor is made of high-purity electrolytic copper with a purity of over 99.95%. High-purity copper has excellent conductivity, which can effectively reduce the resistance during current transmission, reduce energy loss, improve power transmission efficiency, and thus reduce electricity costs. Copper has good ductility and toughness. The multi-strand twisted conductor design makes the cable not easy to break when bent or stretched, and can adapt to complex wiring environments, extending the service life of the cable. Compared with conductors of other materials, Copper Conductors have stronger oxidation resistance and corrosion resistance, and can maintain stable conductivity during long-term use, providing a solid guarantee for the safe operation of the cable.

The insulation layer is made of cross-linked polyethylene (XLPE) material. XLPE material has excellent insulation performance, with a volume resistivity greater than 10¹⁶Ω·cm, which can effectively insulate current, prevent electric leakage accidents, and ensure the safety of power transmission. It has excellent temperature resistance, and will not age or crack when used for a long time in a 90°C humid environment, greatly extending the service life of the cable. Moreover, XLPE material also has good chemical corrosion resistance, which can resist the erosion of various chemical substances such as acids, alkalis, and salts that may exist in humid environments, ensuring the stable operation of the cable in complex environments. At the same time, XLPE material has high mechanical strength and good impact resistance, which can protect the conductor from external mechanical damage.

In terms of style, the cable has a circular structure, which is cylindrical as a whole with a smooth and flat surface. This design makes the cable have low resistance during wiring, easy to thread and pay off, and can easily pass through narrow spaces such as walls and underground pipes, improving construction efficiency. The cable has a variety of colors. Cables of different specifications are usually marked with different colors. For example, 10mm² may be black, 16mm² may be red, 25mm² may be blue, etc. This is convenient for electricians to quickly identify cables of different specifications during construction and maintenance, avoid wrong wiring, and ensure the accuracy and safety of the power distribution system.

Multi-strand stranding is an important style feature of the cable, and the conductor is made of multiple strands of fine Copper Wires twisted together. This design enhances the Flexibility of the cable, making it more flexible when bent, and can adapt to various complex wiring paths, especially at corners and narrow spaces, which can better reflect its advantages. At the same time, the multi-strand twisted structure can also reduce the skin effect when the cable transmits current, improve the conductivity efficiency, and reduce energy loss. The outer layer of the cable usually has a sheath, which is made of weather-resistant materials, further enhancing the wear resistance, aging resistance, chemical corrosion resistance and other properties of the cable, enabling it to work reliably in various harsh environments.

The production process of XLPE copper cables adopts advanced and rigorous techniques to ensure that the product quality meets relevant standards and application scenario requirements.

The first step is the preparation of copper materials. High-purity electrolytic copper ingots are made into copper rods through processes such as heating and rolling. During the rolling process, the heating temperature and rolling speed are strictly controlled to ensure the uniformity and mechanical properties of the copper rod. The heating temperature is generally controlled near the melting point of copper (about 1083°C) to fully melt the copper ingot, ensuring that the rolled copper rod has a uniform texture. The rolling speed is accurately adjusted according to the diameter requirements of the copper rod to ensure the dimensional accuracy of the copper rod.

Next is the wire drawing process. The copper rod is drawn into multiple strands of fine copper wires by a wire drawing machine. The wire drawing process adopts multi-pass drawing, and the drawing die and drawing speed of each pass are precisely calculated and controlled. The drawing die is made of high-strength diamond, which can ensure the dimensional accuracy and surface smoothness of the copper wire. A special lubricant is used during the wire drawing process. The lubricant is made of mineral oil and additives, which can effectively reduce friction between the copper wire and the die, prevent damage to the surface of the copper wire, and ensure that the conductivity of the copper wire is not affected.

Then is the stranding process. Multiple strands of fine copper wires are twisted according to a certain stranding method and pitch to form a conductor. The stranding method adopts regular stranding to ensure that each strand of copper wire is evenly stressed and reasonably distributed. The size of the stranding pitch is strictly controlled according to the specifications of the cable, generally 10-20 times the diameter of the conductor, to ensure that the conductor has good flexibility and conductivity. Special equipment is used during the stranding process, and through precise mechanical transmission, the accuracy and stability of stranding are ensured, avoiding phenomena such as loose strands and broken strands.

After stranding, the insulation extrusion process is carried out. XLPE material is added to the extruder, heated to 180-200°C to melt it, and then evenly extruded and coated on the outside of the conductor through an extrusion die to form an insulation layer. During the extrusion process, the extrusion temperature, speed and pressure are precisely controlled to ensure that the insulation layer has a uniform thickness, a smooth surface, is closely combined with the conductor, and has no defects such as bubbles and impurities. The control of extrusion temperature is crucial. Excessively high temperature will cause the decomposition of XLPE material, affecting the insulation performance; excessively low temperature will make the material have poor fluidity, leading to uneven insulation layers.

The extruded cable needs to undergo cross-linking treatment, which is a key process in the production of XLPE Cables. Cross-linking treatment usually adopts warm water cross-linking or steam cross-linking to transform the XLPE molecular structure from linear to network, thereby improving its temperature resistance, mechanical strength and chemical corrosion resistance. Warm water cross-linking involves immersing the cable in 80-90°C warm water for a certain period of time (usually several hours to several days); steam cross-linking is carried out in a high-temperature and high-pressure steam environment, with a relatively short time. The time and temperature of cross-linking treatment are precisely controlled according to the specifications of the cable and the characteristics of the XLPE material to ensure that the cross-linking degree meets the requirements.

The cross-linked cable is cooled by means of water cooling to quickly cool the cable to room temperature, so that the insulation layer is solidified and formed. During the cooling process, the water temperature and cooling time are strictly controlled to avoid cracks in the insulation layer due to too fast cooling or affecting production efficiency due to too slow cooling.

The cooled cable also needs to undergo a series of quality inspections, including appearance inspection, size inspection, electrical performance inspection, and mechanical performance inspection. Appearance inspection mainly checks whether the cable surface is smooth, the color is uniform, and there are no scratches, etc.; size inspection measures whether the outer diameter of the cable, the thickness of the insulation layer, etc. meet the specifications; electrical performance inspection includes insulation resistance test, voltage withstand test, etc. to ensure good insulation performance of the cable; mechanical performance inspection includes tensile test, bending test, impact test, etc. to evaluate the flexibility, mechanical strength and impact resistance of the cable.

The cables that pass the quality inspection enter the coiling and packaging process. The cables are coiled according to the specified length, and a coiling machine is used to neatly wind the cables on reels or spools, and then packaged to protect the cables from damage during transportation and storage.

The packaging design of XLPE copper cables focuses on protecting the product, facilitating transportation and storage, while emphasizing the clarity of identification and the convenience of use.

For coiled cables, different packaging methods are adopted according to different lengths. Cables with lengths of 100 meters, 200 meters, and 500 meters usually use hard paper tubes or plastic reels as inner packaging. The diameter of the paper tube or reel is adjusted according to the specifications of the cable to ensure that the cable can be tightly and neatly wound on it. Both ends of the paper tube or reel are equipped with plastic or metal end caps. The end caps are connected to the paper tube or reel by 卡扣 or bolts, which are firm and reliable, and can effectively prevent the cable from slipping off from both ends. After the cable is wound, it is wrapped with a layer of thickened plastic film. This film has good moisture-proof, dust-proof and wear-resistant properties, and can protect the insulation layer and conductor of the cable from damage during transportation and storage, especially in humid environments, it can effectively isolate water vapor and prevent the cable from getting damp.

For shorter cables, such as 10 meters, 20 meters, 50 meters, etc., high-strength plastic packaging bags are used for packaging. The packaging bag is made of tear-resistant polyethylene material with a thickness of more than 0.15mm, which has good toughness and wear resistance, can withstand a certain amount of extrusion and collision, and protects the cable from damage. Each packaging bag contains a coil of cable, and the bag mouth is designed with a self-sealing strip. The self-sealing strip has strong viscosity, can be sealed repeatedly, is convenient to open and close, and can also effectively prevent moisture and dust from entering the bag.

Whether it is paper tube, reel packaging or plastic packaging bag packaging, clear product labels are affixed to prominent positions. The label is made of waterproof and wear-resistant material, and clearly marks the product name (XLPE copper cable), model, specification (cross-sectional area and length), rated voltage (600V/1000V), temperature resistance level (90°C in humid environment), execution standard (Xhhw-2, RW90, Thhn/Thwn-2, etc.), production date, batch number, manufacturer name, address, contact information, etc. The text and patterns on the label are clear and eye-catching, and are not easy to blur or fall off even during long-term storage or transportation, which is convenient for users to quickly identify and check product information during receipt, use and maintenance.

For cables transported in batches, multiple paper tubes, reels or packaging bags are neatly placed in strong cartons or wooden boxes. The carton is made of five-layer corrugated paper, which has high compressive strength; the wooden box is made of high-quality solid wood boards, which have been anti-corrosion treated and are firm and durable. The inside of the box is filled with buffer materials such as foam boards, bubble films, and pearl cotton according to the shape and size of the cable. These buffer materials can effectively absorb the impact force during transportation, avoiding damage caused by collision and friction between cables. The outside of the box is reinforced with packing belts, which are made of high-strength polyester materials to ensure that the box will not fall apart during transportation. The surface of the box is also affixed with eye-catching signs, including product name, specification, quantity, gross weight, net weight, transportation precautions (such as "handle with care", "moisture-proof", "sun-proof", etc.), which is convenient for logistics and transportation personnel to load, unload and carry and handle, and also reminds storage personnel to pay attention to relevant matters.

The transportation of XLPE copper cables strictly complies with relevant regulations and standards to ensure that the products are delivered to the destination safely and on time.

For short-distance domestic transportation (usually within 500 kilometers), road transportation is generally adopted, using enclosed trucks for loading. The truck compartment must be clean, dry, and odor-free, with no sharp protrusions or debris inside to prevent scratching the cable packaging and insulation layer. When loading, the packaged cables are neatly stacked in the compartment. Cables with larger specifications and heavier weights are placed at the bottom, and those with smaller specifications and lighter weights are placed on top. The stacking height does not exceed 80% of the compartment height to ensure stability during driving. Cables are separated by partitions or buffer materials to avoid mutual collision and extrusion. For cables packaged in paper tubes or reels, when placed horizontally, ensure they will not roll. They can be fixed to the side walls or bottom of the compartment with ropes or straps. The fixing force should be moderate, which can prevent the cables from moving without excessive extrusion that causes packaging deformation or cable damage.

For long-distance transportation (more than 500 kilometers), railway transportation or water transportation can be chosen. Railway transportation has the advantages of large transportation volume, good stability, and little impact from weather, making it suitable for transporting large quantities of cables. The cables are loaded into railway boxcars or containers, and dry cargo containers are selected to ensure the interior is dry and clean. During loading, attention should also be paid to the stacking order and fixation to prevent the cables from shifting during transportation. Water transportation is suitable for cross-regional or coastal transportation. The cables are loaded into the cargo hold of the freighter, and the cargo hold is moisture-proof and salt-fog resistant. A layer of waterproof canvas or plastic film is covered on the outside of the packaging to further enhance the moisture-proof effect and prevent seawater or moisture from eroding the cables.

During transportation, a series of measures are taken to prevent the cables from being affected by adverse environmental factors. When transporting in summer, due to high temperatures, the cables should be avoided from being exposed to direct sunlight for a long time. Sun visors or heat insulation layers can be installed on the top of the truck or inside the container to reduce the internal temperature and prevent the XLPE insulation layer from accelerating aging due to high temperatures. When transporting in winter, if the temperature is too low (below -10°C), the cables should be avoided from severe impact, because low temperatures will reduce the toughness of the XLPE material, making it prone to brittle fracture. During loading and unloading, handle with care. In rainy or humid weather, ensure that the transportation tools have good sealing performance to prevent rainwater from entering the compartment or cargo hold. At the same time, check whether the cable packaging is intact. If there is any damage, repair or replace the packaging in a timely manner.

Transportation personnel must be familiar with the characteristics and transportation requirements of the cables. Before transportation, a comprehensive inspection of the loading situation is carried out to ensure that the cables are firmly fixed and the packaging is intact. During transportation, abide by traffic rules, avoid sudden braking, sharp turns, overspeeding and other behaviors that may cause impact and vibration to the cables. For long-distance transportation, stop regularly to check the condition of the cables. If packaging damage or cable displacement is found, handle it in a timely manner. In case of severe weather (such as heavy rain, heavy snow, typhoon, etc.) during transportation, stop at a safe place and continue transportation after the weather improves.

The shipping process of XLPE copper cables is standardized and orderly, aiming to provide customers with efficient, accurate and satisfactory services.

After the customer places an order, the sales staff will conduct a detailed review of the order information, including the cable specification (cross-sectional area and length), quantity, delivery time, delivery address, consignee, and contact information. If there is any ambiguous information in the order, the sales staff will communicate with the customer in a timely manner to confirm, ensuring that the order information is accurate and complete, and laying a good foundation for the smooth progress of the subsequent shipping work.

After the order is confirmed, the sales department will issue a picking list to the warehouse department. The warehouse staff will check the inventory according to the picking list. If the required cables are in stock, they will start picking immediately. During the picking process, carefully check the product labels to ensure that the specification, batch number, and production date of the picked cables are consistent with the order requirements. At the same time, inspect the packaging of the cables to ensure that the paper tubes, reels, or plastic bags are intact, without damage, moisture, or other phenomena that may affect the quality of the cables.

For customers who need a large number of samples or have special requirements, the specific sample fee and shipping cost can be negotiated separately.

After the sample application is approved, the warehouse department will select cables that meet the quality standards from the qualified products as samples. The samples must be representative, with complete packaging and clear labels, consistent with the formal products in terms of material, structure, and performance. Before sending the samples, the quality inspection department will conduct a simple inspection on the samples, including checking the appearance of the insulation layer, the tightness of the conductor stranding, etc., to ensure that the samples are in good condition.

The samples are usually shipped by express delivery, which is fast and convenient, and can ensure that the samples reach the customer in a short time. Common express companies include DHL, FedEx, UPS, etc., and the appropriate express company is selected according to the customer's location. After the samples are shipped, the sales department will promptly inform the customer of the express waybill number and estimated arrival time, so that the customer can track the sample logistics information.

After the customer receives the sample, if they have any questions about the sample's performance, installation, or use, they can contact the company's technical support personnel.
