The U1000 Rvfv XLPE Power Cable 4G 16mm² fully considers performance, safety and usage needs in material selection and style design to ensure that the product can perform well in various complex environments.

In terms of materials, the conductor is made of high-purity electrolytic copper with a purity of more than 99.95%. High-purity copper has excellent conductivity, which can reduce the resistance during current transmission, reduce energy loss, and improve the efficiency of electrical energy transmission. At the same time, electrolytic copper has good ductility and plasticity, and can withstand mechanical actions such as bending and stretching during cable production and laying without breaking, ensuring the service life of the cable. In addition, copper has good thermal conductivity, which can timely dissipate the heat generated by the cable during operation, avoiding the impact on the cable's performance due to overheating.

The insulation layer is made of cross-linked polyethylene (XLPE) material, which forms a three-dimensional network molecular structure after special cross-linking treatment. Compared with traditional polyethylene materials, its mechanical strength, temperature resistance and aging resistance have been significantly improved. The temperature resistance range of XLPE material is extended to -40°C to 90°C, which can work stably for a long time in environments with alternating high and low temperatures, and will not cause the insulation performance to decline due to temperature changes. At the same time, it has high insulation resistance and good chemical corrosion resistance, which can effectively resist the erosion of moisture, dust and chemical substances, ensuring the long-term stability of the cable's insulation performance.

The sheath of the RVFV model is made of flame-retardant polyvinyl chloride (PVC) material, which has dual protection functions. On the one hand, it forms a mechanical barrier by tightly covering the insulation layer, with an impact strength of 12kJ/m², which can withstand mechanical actions such as dragging and extrusion during construction, and protect the internal insulation layer and conductor from damage. On the other hand, by adding a halogen inhibition formula, the sheath reaches the GB/T 18380.3-2008 Class B flame retardant grade. In case of fire, it can delay the spread of flames, reduce the generation of smoke and the release of toxic gases, and create favorable conditions for personnel evacuation and fire rescue.

In terms of style design, the cable adopts a 4-core stranded structure, which makes the cable have good flexibility, with a bending radius ≥12 times the outer diameter, facilitating installation and laying in various complex wiring environments. The 4 Cores are 3 phase wires and 1 grounding core respectively, with clear color distinction. The phase wires usually adopt yellow, green and red colors, and the grounding core adopts yellow-green 双色. This color identification is convenient for construction personnel to accurately identify during installation, avoiding wiring errors, and improving construction efficiency and safety.

The appearance of the cable is black, which is due to the flame-retardant PVC material used for the sheath. The black appearance is not only beautiful and generous but also has certain light resistance, which can reduce the aging effect of direct sunlight on the cable. On the surface of the sheath, each meter is printed with clear marks, including model, cross-section, standard number, manufacturer and other information. These marks not only facilitate users to identify and trace the product but also reflect the standardized production of the product.

In addition, the structure of the cable is compact, and the materials of each layer are firmly bonded, which can prevent moisture, dust and other impurities from entering the cable, ensuring that the performance of the cable is not affected. At the same time, the weight of the cable is reasonably designed, which not only ensures the strength and performance of the product but also facilitates transportation and installation.

The production process of U1000 Rvfv XLPE Power Cable 4G 16mm² is advanced and rigorous. Each process is strictly controlled and inspected to ensure that the quality and performance of the product meet the design standards.

The first is the manufacturing process of the conductor. High-purity electrolytic copper rods are selected as raw materials, and the copper rods are drawn into Copper Wires with the required diameter through a wire drawing machine. During the wire drawing process, it is necessary to accurately control the drawing speed, die size and cooling method to ensure that the diameter of the copper wire is uniform, the surface is smooth, and defects such as burrs and scratches are avoided. The drawn copper wire needs to be annealed. The copper wire is heated to a certain temperature (usually 300°C ~ 500°C) and kept warm for a period of time, then slowly cooled to eliminate internal stress in the copper wire and improve its flexibility and conductivity. The annealed copper wires are stranded through a bunching machine to form a 16mm² single-core conductor. During the stranding process, the stranding pitch and tension must be strictly controlled to ensure that the structure of the conductor is tight and round, reducing the skin effect during current transmission and improving the conductivity efficiency.

Next is the extrusion and cross-linking process of the insulation layer. Cross-linked polyethylene (XLPE) material is used as the insulation layer. First, the XLPE particles are pretreated to remove moisture and impurities to ensure the quality of the insulation layer. Then, the pretreated XLPE material is evenly coated on the surface of the conductor through an extruder to form an insulation layer. During the extrusion process, it is necessary to accurately control the extrusion temperature, pressure and speed to ensure that the insulation layer has uniform thickness, smooth surface, and is tightly bonded to the conductor. The extruded Insulated Wire core needs to be cross-linked. The commonly used cross-linking methods are dry cross-linking and warm water cross-linking. Dry cross-linking is to put the insulated wire core into a cross-linking tube and carry out cross-linking reaction in a high-temperature and high-pressure nitrogen environment; warm water cross-linking is to soak the insulated wire core in warm water and initiate cross-linking reaction through water as a medium. After cross-linking treatment, XLPE molecules form a three-dimensional network structure, which significantly improves the temperature resistance, mechanical strength and insulation performance of the insulation layer.

Then there is the cabling process. The 4 insulated wire cores (3 phase wires and 1 grounding core) are stranded into a cable according to a certain stranding direction and pitch. In the cabling process, in order to ensure the roundness and stability of the cable, it is necessary to fill appropriate filling materials, such as polypropylene rope, between the insulated wire cores. The filling material should have good flexibility and corrosion resistance, which can buffer the interaction between the wire cores and reduce wear during laying. After cabling, a layer of non-woven fabric or polyester tape is wrapped around the cable to play the role of binding and isolation, preventing the wire cores from loosening and the sheath material from seeping into the wire cores.

Finally, the extrusion process of the sheath is carried out. Flame-retardant polyvinyl chloride (PVC) material is used as the sheath. PVC particles are mixed with flame retardants, stabilizers and other additives in a certain proportion, and then the mixture is evenly coated on the outside of the cabled cable core through an extruder to form a sheath. During the extrusion process, it is necessary to control the extrusion temperature, pressure and speed to ensure that the sheath has uniform thickness, smooth surface, and is tightly bonded to the cable core. The thickness of the sheath should meet the design requirements to ensure that it can provide effective mechanical protection and flame retardant performance for the cable. After extrusion, the cable is cooled to make it solidify quickly.

During the entire production process, multiple quality inspection procedures are required. After the conductor is manufactured, its diameter, DC resistance and other parameters are tested to ensure compliance with standards; after the insulation layer is extruded and cross-linked, its thickness, insulation resistance, voltage withstand performance, etc., are tested; after cabling, the structural size and roundness of the cable are tested; after the sheath is extruded, its thickness, appearance, flame retardant performance, impact strength, etc., are tested. In addition, the finished cable also needs to undergo overall performance tests such as power frequency withstand voltage test, partial discharge test, and aging test. Only products that meet the requirements in all indicators can leave the factory.

Advanced automatic control technology and online monitoring equipment are adopted in the production process to monitor and adjust various parameters in the production process in real time, ensuring the stability and consistency of the production process. At the same time, the environment of the production workshop is strictly controlled to keep it clean, dry and constant temperature, avoiding the impact of dust, humidity and other factors on product quality.

The packaging design of U1000 Rvfv XLPE Power Cable 4G 16mm² fully considers the product's protection, transportation and storage needs, and adopts a scientific and reasonable packaging method to ensure that the cable remains in good quality before reaching the user.

The cable is usually packaged with cable reels, which are available in wooden and steel types. For short-distance transportation, small-batch shipments or indoor storage, wooden cable reels are a more economical choice. Wooden cable reels are relatively light in weight, relatively low in cost, and easy to manually carry and load/unload. However, the strength of wooden cable reels is relatively low, and their impact resistance is poor, so they are not suitable for long-distance transportation or storage in harsh environments.

Steel cable reels have high strength, high load-bearing capacity and good impact resistance, and are suitable for long-distance transportation, large-batch shipments and outdoor storage. Steel cable reels can withstand the weight of the cable and various external impacts during transportation, effectively protecting the cable from damage. The surface of steel cable reels is usually subjected to anti-corrosion treatment, such as painting and galvanizing, to prevent rust during transportation and storage and extend their service life.

When the cable is wound onto the cable reel, it needs to be done according to a certain tension and order to ensure that the cable is arranged neatly and tightly, avoiding looseness, distortion or mutual friction. During the winding process, the winding speed must be controlled to avoid excessive stretching or extrusion of the cable due to too fast speed, which will affect the performance of the cable. After winding, sealed 封头 are installed at both ends of the cable to prevent moisture, dust and other impurities from entering the cable.

To further protect the cable, a layer of plastic film is wrapped around the outside of the cable reel. The plastic film has good moisture-proof and dust-proof properties, which can prevent the cable from getting damp and contaminated with dust during transportation and storage. For cables that need to be stored for a long time, a layer of linen or canvas can be wrapped around the outside of the plastic film. Linen or canvas has certain air permeability and wear resistance, which can protect the cable reel from collision and friction, and also play a role in sun protection and ultraviolet protection, delaying the aging of the cable sheath.

The cable reel will be clearly marked with relevant product information, including product name, model specification (U1000 Rvfv XLPE Power Cable 4G 16mm²), length, weight, manufacturer, production date, implementation standard, certification mark, etc. This information is convenient for users to check and identify when receiving and accepting products, and is also conducive to product traceability and management. Lifting holes are also installed on the side of the cable reel to facilitate lifting and handling with cranes and other equipment.

For exported cables, the packaging also needs to meet international transportation standards and the import requirements of relevant countries. For example, wooden cable reels need to be fumigated to prevent the spread of diseases and pests; the marks on the packaging need to be in English or the language of the destination country to ensure clear understanding by foreign customers. Additionally, export packaging must comply with customs inspection requirements and facilitate loading/unloading operations at ports.
