Low Voltage XLPE Insulated Power Cable PVC Insulation 10mm 16mm 25mm 4 Core Aluminium Underground Electric Wire

The specification parameters of low voltage XLPE insulated, PVC insulated 10mm, 16mm, 25mm 4-core aluminum underground wires are crucial for their adaptation to underground power transmission scenarios. Each parameter is carefully designed to meet the requirements of different environments and power levels.

In terms of conductor specifications, this series of wires adopts 4-core Aluminum Conductors with an aluminum purity of over 99.5%. This high-purity aluminum conductor ensures a certain level of conductivity while effectively controlling costs. The cross-sectional areas of the conductors are 10mm², 16mm², and 25mm², which are determined based on the common power requirements in underground power transmission. For a 10mm² conductor, its diameter is approximately 3.5mm, with a maximum current-carrying capacity of about 50A at 25°C, which can meet the power supply needs of equipment with a power of around 10kW; a 16mm² conductor has a diameter of about 4.5mm and a maximum current-carrying capacity of approximately 65A, capable of handling power transmission of around 13kW; a 25mm² conductor has a diameter of about 5.6mm and a maximum current-carrying capacity of about 85A, which can satisfy the power demand of high-power equipment around 17kW. In the 4-core structure, 3 cores are phase wires, and 1 Core is a neutral wire. The cross-sectional area of the neutral wire is the same as that of the phase wires, ensuring normal operation when the three-phase current is unbalanced.

The specifications of the insulation layer vary depending on the material. The thickness of the XLPE insulation layer changes with the cross-sectional area of the conductor. The XLPE insulation layer thickness corresponding to a 10mm² conductor is approximately 0.8mm, 16mm² is about 1.0mm, and 25mm² is around 1.2mm. XLPE Insulation Material has extremely high insulation resistance, with a volume resistivity greater than 1×10¹⁴Ω·cm and a dielectric loss tangent less than 0.001. It can maintain good insulation performance at a rated voltage of 0.6/1kV and has a wide operating temperature range, being able to work stably between -40°C and 90°C. The PVC Insulation layer is relatively thicker. The PVC insulation layer thickness for a 10mm² conductor is about 1.0mm, 16mm² is approximately 1.2mm, and 25mm² is around 1.4mm. PVC Insulation Material has a volume resistivity greater than 1×10¹³Ω·cm and a dielectric loss tangent less than 0.03, with an operating temperature range of -15°C to 70°C. Although its insulation performance is slightly inferior to that of XLPE, it can meet the insulation requirements of general underground environments.

The rated voltage of this series of wires is 0.6/1kV, where 0.6kV is the voltage between the conductor and the ground, and 1kV is the voltage between conductors. It fully complies with the standards of low-voltage distribution systems and can be safely applied to various low-voltage underground power transmission scenarios. In addition, the overall outer diameter of the wires varies with specifications. The outer diameter of a 10mm² 4-core XLPE Insulated Wire is approximately 15mm, 16mm² is about 18mm, and 25mm² is around 22mm; the outer diameter of PVC Insulated Wires is slightly larger, with 10mm² being about 16mm, 16mm² about 19mm, and 25mm² about 23mm. These outer diameter parameters provide an important reference for the laying of wires in underground pipes and cable trenches, ensuring that they can smoothly pass through preset channels.

The bending radius of the wire is also an important parameter. The minimum bending radius of XLPE Insulated Wires is 12 times the outer diameter, and that of PVC Insulated Wires is 10 times the outer diameter. This allows the wires to be properly bent in narrow underground spaces without damaging the insulation layer and conductor. At the same time, this series of wires is lightweight. A 10mm² XLPE insulated wire weighs about 0.25kg per meter, 16mm² about 0.35kg, and 25mm² about 0.5kg; PVC insulated wires are about 0.05-0.1kg heavier per meter than XLPE insulated wires of the same specification. This weight characteristic greatly reduces the labor intensity during transportation and laying.

Low voltage XLPE insulated, PVC insulated 10mm, 16mm, 25mm 4-core aluminum underground wires, with their unique performance, have irreplaceable characteristic uses in underground power transmission in multiple fields.

In urban infrastructure construction, this series of wires plays an important role. The street lamp power supply systems on both sides of urban roads mostly adopt underground wiring. A 10mm² XLPE or PVC insulated wire can meet the power demand of a single street lamp. Its 4-core structure can transmit three-phase power and neutral wire at the same time, ensuring the stable operation of street lamps. As an important facility for urban traffic management, traffic signals have high requirements for the reliability of power supply. A 16mm² wire, with its large current-carrying capacity, can provide stable power for multiple signal groups, and the underground laying method can avoid interference and damage to the line from external factors. In addition, this series of wires is often used for power supply of lighting and ventilation equipment in urban underground parking lots, underground passages, etc. Depending on power requirements, 10mm² and 16mm² wires are more commonly used.

The underground power distribution system in residential communities is another important application scenario for this series of wires. The underground garages in the community need to supply power to lighting, charging piles, ventilation systems and other equipment. A 16mm² wire can be used as the main power distribution line in the garage, transmitting power from the distribution room to the distribution boxes in each partition, and then supplying power to specific equipment through branch lines. The underground wiring under the green belts in the community is mainly used to supply power to lawn lamps, sprinkler systems and other equipment. A 10mm² wire becomes an ideal choice for such scenarios due to its low cost and ability to meet power requirements. For the underground connection line from the small transformer in the community to the main distribution box of the residential building, a 25mm² wire can meet the total power transmission demand of multiple residential buildings.

This series of wires is also widely used in underground Power Lines in industrial plants. For underground power supply lines of some small and medium-sized production equipment, such as motors and conveyors in assembly lines, 16mm² or 25mm² wires can be selected according to the power. XLPE insulated wires, with their good heat resistance, are more suitable for use in underground pipes with higher ambient temperatures in industrial plants. For underground power supply lines of storage facilities in the plant area, such as cold storage, PVC insulated wires can adapt to the low-temperature environment around the cold storage and supply power to the refrigeration equipment and lighting systems of the cold storage. In addition, for underground wiring in industrial wastewater treatment plants, due to the possible presence of corrosive substances in the environment, the corrosion resistance of PVC insulated wires makes them the first choice, and 25mm² wires can meet the high-power demand of wastewater treatment equipment.

The underground power transmission in the agricultural field is also inseparable from this series of wires. The lighting, temperature control, irrigation and other equipment in greenhouses need stable power supply. Underground wiring can prevent the lines from being damaged by exposure to the external environment. 10mm² or 16mm² wires can meet the power demand of greenhouses of different scales. The underground power supply lines of farmland irrigation systems need to resist the erosion of moisture and microorganisms in the soil. The aging resistance and corrosion resistance of XLPE insulated wires enable them to work stably for a long time, and 25mm² wires can provide sufficient power for large irrigation pumps. At the same time, in the transformation of underground power distribution networks in rural concentrated residential areas, this series of wires is widely used to connect transformers and household incoming lines due to their economy and applicability.

This series of wires can also play their role in underground wiring in some special places. For example, for power supply of underground lighting and background music systems in parks and scenic spots, 10mm² wires can meet the demand, and underground laying will not affect the overall landscape of the scenic spot. The underground power supply lines in stadiums supply power to venue lighting, electronic displays and other equipment. 16mm² or 25mm² wires can cope with large power demand, ensuring stable power during events.

Low voltage XLPE insulated, PVC insulated 10mm, 16mm, 25mm 4-core aluminum underground wires, in terms of material selection and style design, fully consider the particularity of the underground environment and the requirements of power transmission, forming unique product characteristics.

In terms of materials, the conductor is made of high-purity aluminum rods through wire drawing, annealing and other processes. High-purity aluminum not only ensures good conductivity but also has good ductility, making it easy to process into wires of different cross-sectional areas. During the wire drawing process, the aluminum rod is drawn into Aluminum Wires of the required diameter, and then multiple Aluminum Wires are stranded to form a conductor. The Stranded Conductor structure is more stable, which can reduce the skin effect and improve the conductivity efficiency. At the same time, a dense aluminum trioxide protective film will naturally form on the surface of the aluminum conductor. This protective film can effectively prevent further oxidation of aluminum, enhance the corrosion resistance of the conductor, and enable it to be used for a long time in underground humid environments with many corrosive media.

The insulation layer materials are divided into XLPE and PVC. XLPE (cross-linked polyethylene) is a polyethylene material that has undergone cross-linking treatment. Through chemical or physical methods, the polyethylene molecules are transformed from a linear structure to a three-dimensional network structure, thereby significantly improving the material's heat resistance, mechanical strength and aging resistance. XLPE Insulation Material has excellent electrical performance, with high insulation resistance and low dielectric loss. It can maintain stable insulation effect at high temperatures and has strong resistance to environmental stress cracking. Even if it is affected by soil pressure, temperature changes and other factors underground, it is not easy to crack. PVC (polyvinyl chloride) insulation material is made of polyvinyl chloride resin with plasticizers, stabilizers, fillers and other additives. It has good mechanical properties and chemical corrosion resistance, and the price is relatively low. PVC material has good Flexibility, which is convenient for bending and laying of wires, and has certain flame retardant performance, which can delay the spread of flames to a certain extent.

The style design of this series of wires is centered on adapting to underground laying. The overall structure is circular, with 4 insulated wire cores stranded together to form a Compact Cable core. The stranding method adopts regular stranding, that is, each wire core is stranded according to a certain pitch and direction. The pitch is usually 10-16 times the outer diameter of the wire. This stranding method enables the wire to have good flexibility and structural stability, and is not easy to deform during laying. The outside of the cable core is usually wrapped with a layer of non-woven fabric or polypropylene tape as the inner lining layer, which can play a buffering and isolating role, protecting the insulation layer from damage during stranding and subsequent processing.

For scenarios that need to withstand large mechanical external forces, some models of wires will add a layer of Steel Tape armoring outside the cable core. The steel tape armoring layer is made of low-carbon steel tape, which is wrapped around the cable core by longitudinal wrapping or spiral wrapping. It can significantly improve the compressive and impact resistance of the wire, protecting the internal structure from mechanical damage such as underground soil pressure and stone extrusion. A layer of PVC outer sheath is extruded outside the armoring layer. The outer sheath is usually black, which has good light resistance, can reduce the aging effect of direct sunlight on the sheath, and is convenient for identification underground.

In addition, the insulated wire cores of the wires are distinguished by different colors. Usually, phase A is yellow, phase B is green, phase C is red, and the neutral wire is blue or black. This color identification is convenient for construction personnel to accurately identify each phase conductor during installation and maintenance, avoiding wiring errors. The surface of the wire core is smooth, without burrs and protrusions, ensuring that the insulation layer of adjacent wire cores will not be damaged during stranding and laying.

The production process of low voltage XLPE insulated, PVC insulated 10mm, 16mm, 25mm 4-core aluminum underground wires is complex and rigorous. Each process has an important impact on product quality. Various parameters need to be strictly controlled from raw material processing to finished product inspection.

The production process of the conductor is a basic link. First, high-purity aluminum rods are put into a wire drawing machine for wire drawing processing. The wire drawing machine draws the aluminum rods into aluminum wires of the required diameter through a die. During the wire drawing process, it is necessary to control the wire drawing speed and the temperature of the die. Generally, the wire drawing speed is 8-15m/s, and the die temperature is maintained at 80-120°C to ensure the dimensional accuracy and surface quality of the aluminum wires. The drawn aluminum wires need to be annealed. The aluminum wires are put into an annealing furnace, heated at 300-400°C for 1-2 hours, and then slowly cooled. Annealing can eliminate the internal stress generated during the wire drawing process and improve the flexibility and conductivity of the aluminum wires. The annealed aluminum wires are stranded according to the required cross-sectional area. Multiple aluminum wires are stranded on a stranding machine according to a certain stranding direction and pitch to form a conductor. The stranding pitch is usually 10-15 times the outer diameter of the conductor to ensure the roundness and structural stability of the conductor.

The extrusion process of the insulation layer varies with the material. For the XLPE insulation layer, first, XLPE granules are added into the hopper of the extruder. The screw of the extruder conveys the granules to the heating zone, where the granules are melted and plasticized at a temperature of 120-150°C. The melted XLPE material is evenly coated on the surface of the conductor through an extrusion die to form an insulation layer. The size of the extrusion die is accurately designed according to the thickness of the insulation layer to ensure uniform thickness of the insulation layer. The extruded insulated wire core needs to undergo cross-linking treatment. Using warm water cross-linking or steam cross-linking, the insulated wire core is placed in hot water or steam at 90-100°C for 4-6 hours to make the XLPE molecules undergo cross-linking reaction to form a stable network structure. The cross-linked insulated wire core is cooled and then inspected for appearance and size.

For the PVC insulation layer, the production process is relatively simple. PVC resin is mixed with plasticizers, stabilizers, fillers and other additives in proportion to make PVC mixture. After the mixture is added into the extruder, it is melted and plasticized at a temperature of 160-180°C, and coated on the surface of the conductor through an extrusion die to form an insulation layer. During the extrusion process, it is necessary to control the extrusion pressure and speed to ensure the compactness and surface smoothness of the insulation layer. The extruded PVC insulated wire core is directly cooled without cross-linking treatment.

The stranding process of the 4-288ac2925daeccfc5b451252efd0f404 Core is the process of combining four insulated wire cores into a cable core. First, each insulated wire core is inspected for appearance and size. After ensuring that it is qualified, it is placed on the pay-off rack of the stranding machine. The stranding machine strands the four wire cores according to the preset stranding direction (usually right-hand) and pitch (generally 12-20 times the outer diameter of the cable core). During the stranding process, it is necessary to keep the tension of each wire core uniform to avoid loosening, twisting and other phenomena. For 25mm² wires with a large cross-sectional area, in order to ensure the roundness of the cable core, polypropylene filling rope is added during stranding to fill the gaps between the wire cores. The outside of the Stranded Cable core is wrapped with a layer of non-woven fabric or polypropylene tape as the inner lining layer, which is wrapped with an overlap rate of 15%-20% to ensure that the cable core is completely covered.

For wires with steel tape armoring, armoring treatment is carried out outside the stranded cable core. Low-carbon steel tape is longitudinally wrapped or spirally wrapped around the cable core through an armoring machine. The overlap rate of the steel tape during spiral wrapping is not less than 15% to ensure the continuity and tightness of the armoring layer. The Armored Cable core enters the outer sheath extruder. The outer sheath material is usually PVC, which is melted and plasticized at a temperature of 160-190°C and then coated outside the armoring layer to form an outer sheath. The thickness of the outer sheath is determined according to the wire specification, generally 1.5-2.5mm, to ensure sufficient mechanical strength.

Finished product inspection is the final link of the production process. The appearance of the wire is inspected to ensure that the surface of the insulation layer and sheath layer is smooth, without bubbles, cracks, depressions and other defects. Dimensional measurement is carried out to check whether the conductor diameter, insulation layer thickness, sheath layer thickness, cable core outer diameter, etc., meet the standard requirements. Electrical performance tests include insulation resistance test and withstand voltage test. The insulation resistance test uses a 500V megohmmeter, and the

measured insulation resistance should not be less than 100MΩ; the withstand voltage test is conducted at 2.5kV for 5 minutes without breakdown. In addition, mechanical performance tests such as tensile strength and elongation at break are also carried out on the wires to ensure they meet relevant standards. Only wires that pass all inspections can be packaged and shipped.

The packaging of low-voltage XLPE insulated, PVC insulated 10mm, 16mm, 25mm 4-core aluminum underground wires is designed to protect the products, facilitate transportation and storage, and takes into account the characteristics of underground wires, adopting targeted packaging methods.

For wires with longer lengths (usually 100 meters, 200 meters, or 500 meters), cable reels are used for packaging. There are two types of cable reels: wooden and steel. Wooden cable reels are made of high-quality pine or fir, consisting of discs on both sides and a central shaft cylinder. The diameter of the discs is determined according to the length and outer diameter of the wires, generally 80-150cm, and the diameter of the shaft cylinder is 30-60cm. Wooden cable reels have low cost and light weight, suitable for short-distance transportation and small-batch shipments. The discs are provided with evenly distributed reinforcing ribs to enhance their load-bearing capacity, and the surface of the shaft cylinder is smooth to avoid damaging the insulation layer when winding the wires. Steel cable reels are welded with high-strength steel plates and galvanized on the surface, having higher strength and corrosion resistance, suitable for long-distance transportation and large-batch shipments. The thickness of the discs and shaft cylinder of steel cable reels is designed according to the load-bearing requirements, which can bear the weight of heavier wires and are not easy to deform.

Before winding the wires onto the cable reels, a layer of polyethylene film with a thickness of 0.05-0.1mm is wrapped around the outer layer of the wires. This film can effectively prevent moisture and dust, protecting the surface of the wires from pollution and scratches. For XLPE insulated wires, which are more sensitive to the humidity of the storage environment, a layer of kraft paper is wrapped outside the polyethylene film to further enhance the moisture-proof effect. When winding the wires, mechanical winding is adopted to ensure that the wires are arranged neatly and tightly on the cable reel without crossing or overlapping, and the winding tension is uniform to avoid damage to the wires due to excessive stretching or loosening. After winding, polypropylene strapping with a width of 15-20mm is used to fix the cable reel on both sides and in the middle, with at least 3 fixing points on each side to ensure that the wires do not loosen during transportation.

A detailed label is fixed on the side of the cable reel. The label is made of waterproof material, including product name, model specification (such as XLPE insulated 4×16mm²), length, weight, production batch number, production date, implementation standard, manufacturer's name, address, and contact information. The label is also marked with warning signs such as "Underground Use", "Moisture-proof", and "Handle with Care" to remind transportation and storage personnel to pay attention to relevant matters.

For short-length wires (usually 10 meters, 20 meters, or 50 meters), coil packaging is adopted. The wires are wound into coils with a diameter of 30-50cm. The outside of the coil is wrapped with a thick plastic film, and then put into a corrugated carton. The carton is printed with product information and handling marks. For 25mm² thick wires, a wooden frame may be added outside the carton to prevent extrusion deformation during transportation.

The transportation of low-voltage XLPE insulated, PVC insulated 10mm, 16mm, 25mm 4-core aluminum underground wires needs to take corresponding measures according to different transportation methods and routes to ensure the safety and integrity of the products.

For road transportation, suitable vehicles are selected according to the quantity and specifications of the wires. For small batches of short-length wires, ordinary vans or trucks can be used; for large batches of cable reel-packaged wires, flatbed trucks or container trucks are required. During loading, the cable reels are placed stably, and the gap between the reels is filled with soft materials such as foam or straw to prevent collision and friction. The cable reels are fixed on the vehicle with steel ropes or chains, and the fixing points are on the strong parts of the reels to avoid damage to the reels. For coil-packaged wires, they are stacked neatly, with a partition between each layer to prevent mutual extrusion. In rainy or snowy weather, the vehicle must be covered with a waterproof tarpaulin to prevent the wires from getting wet.

Railway transportation is suitable for long-distance and large-batch transportation. The wires are loaded into railway freight cars, and the loading method is similar to that of road transportation. The cable reels are fixed with the car body using special fixing devices to ensure that they do not shift during the operation of the train. Attention should be paid to the distribution of goods in the car to avoid uneven weight and affect the safety of transportation. The railway transportation department should be informed in advance of the nature and weight of the goods to facilitate the arrangement of appropriate freight cars and loading and unloading equipment.

Sea transportation is mainly used for export or long-distance transportation across regions. The wires are loaded into containers, and the cable reels are fixed on the container floor with twist locks or steel wires. The container should be checked for water tightness to prevent seawater from entering and damaging the wires. Desiccants can be placed in the container to reduce the humidity inside. For XLPE insulated wires, which are sensitive to moisture, additional moisture-proof packaging can be done, such as wrapping the cable reels with moisture-proof cloth. During transportation, the shipping company should be required to provide real-time tracking of the container's location and status to deal with emergencies in a timely manner.

During the entire transportation process, it is necessary to avoid severe vibration and impact. The driver or escort personnel should check the fixation of the goods regularly, especially after passing through bumpy sections or during loading and unloading. If any looseness or damage is found, it should be dealt with immediately. The transportation route should be planned in advance to avoid roads with poor conditions or restricted transportation, and to ensure that the goods arrive at the destination on time.

The warehouse department checks the inventory according to the order. If there is stock, the goods are picked and inspected; if there is no stock, the production department is notified to arrange production, and the production progress is tracked to ensure that the goods are ready before the delivery date.

Goods preparation involves strict inspection of the wires. Each wire is checked for appearance, size, and packaging to ensure that there are no defects such as scratches, cracks, or loose packaging. For products that need to be shipped in batches, sampling inspection is carried out according to a certain proportion, including electrical performance tests, to ensure that the product quality meets the standards. After the inspection is passed, the wires are sorted and stacked according to the order requirements, and the delivery note is attached.

Document sorting is an important part of the shipping process, especially for export products. The required documents include commercial invoice, packing list, bill of lading, quality certificate, and certificate of origin. The commercial invoice should clearly indicate the product name, model, quantity, unit price, total amount, and payment terms; the packing list should match the actual goods, including the number of packages, gross weight, and net weight; the quality certificate should state that the product meets relevant standards and pass the inspection. These documents are sorted and sealed, and handed over to the logistics company or customer together with the goods.
