2.5mm² 4mm² 10mm² Flexible Electric Wire PVC Insulated Copper Core

Wire Diameter Specifications: This series of products includes three wire diameter specifications: 2.5mm², 4mm², and 10mm². The 2.5mm² wire diameter is relatively thin, suitable for carrying medium-power electrical equipment; the 4mm² wire diameter is slightly thicker, capable of meeting higher power electricity demands; the 10mm² wire diameter is thicker, mainly used in high-current scenarios. These three specifications of wire diameters are precisely designed to adapt to electrical equipment and wiring environments with different powers respectively.

Conductor Structure: All adopt a multi-strand stranded Copper Conductor design. The 2.5mm² conductor is usually made by stranding 19 Copper Wires with a diameter of 0.41mm; the 4mm² conductor is generally composed of 19 copper wires with a diameter of 0.52mm; the 10mm² conductor is formed by stranding 49 copper wires with a diameter of 0.52mm. The multi-strand stranded structure endows the wire with excellent Flexibility, making it easy to bend and fold in complex wiring environments, and also enhances the tensile resistance of the conductor.

Rated Voltage: The rated voltage of all three specifications is 300/500V, which meets the standard requirements of low-voltage power distribution systems and can be safely applied to low-voltage electricity scenarios such as households, commerce, and industry.

Current-Carrying Capacity: The current-carrying capacity increases with the increase of wire diameter. The continuous current-carrying capacity of 2.5mm² is about 25A, which can meet the electricity needs of high-power household appliances such as air conditioners and electric water heaters; the continuous current-carrying capacity of 4mm² is about 32A, which can be used in medium-power scenarios such as small industrial equipment and commercial lighting circuits; the continuous current-carrying capacity of 10mm² is about 57A, suitable for high-current scenarios such as main distribution lines and large motor leads.

Insulation Layer Thickness: The thickness of the insulation layer strictly follows industry standards. The average insulation thickness of 2.5mm² and 4mm² wires is not less than 0.8mm. Due to the higher current-carrying capacity of 10mm² wires, the insulation thickness is increased to more than 1.0mm to ensure the insulation effect. Sufficient insulation thickness can effectively block current leakage and ensure electrical safety.

Temperature Resistance Range: It can work stably in an environment of -15℃ to 70℃. Whether in cold winters or hot summers, it can maintain good performance and adapt to climate conditions in different regions and seasons.

2.5mm² Specification: Suitable for high-power household appliances in families, such as air conditioners, electric water heaters, microwave ovens, etc. In residential decoration, it is often used to connect the lines of these appliances, which can stably provide power for them and ensure the normal operation of the appliances. At the same time, it can also be used in lighting circuits and ordinary socket circuits of some small commercial places to meet basic electricity needs.

4mm² Specification: It can meet the power connection of small industrial equipment, such as small machine tools and blowers. In commercial places, it is suitable for higher-power lighting systems, branch lines of central air conditioners, etc. In addition, it is also widely used in socket circuits and Power Lines of some medium-sized office buildings, and can carry medium-power electrical equipment.

10mm² Specification: Mainly used for main distribution lines, such as the lines from the main distribution box to each distribution box, which can efficiently distribute power to various areas. At the same time, it is also applicable to high-current scenarios such as leads of large motors and power lines of industrial production lines, providing stable power support for large equipment and ensuring the smooth progress of industrial production.

Common Application Scenarios: All three specifications of wires can be used in scenarios such as residential decoration, shopping mall wiring, and factory equipment connection. In residential decoration, choosing the appropriate specification according to different electricity needs can meet the power supply of various household appliances; in shopping mall wiring, reasonable matching can be carried out according to the power requirements of different areas to ensure the normal operation of the shopping mall; in factory equipment connection, it can adapt to equipment with different powers to ensure the continuity of production.

Conductor Material: The conductor part is made of high-purity electrolytic copper with a purity of more than 99.95%. High-purity electrolytic copper has excellent electrical conductivity, which can reduce losses during current transmission and improve the efficiency of power transmission. At the same time, electrolytic copper is soft, which is convenient for multi-strand stranding processing, ensuring the quality and performance stability of the conductor.

Insulation Layer Material: The insulation layer is made of high-quality polyvinyl chloride (PVC) material. PVC material has excellent insulation resistance, which can effectively block current and prevent electric leakage accidents. It also has good corrosion resistance, which can resist the erosion of moisture, dust in the air, and some chemical substances, and prolong the service life of the wire. In addition, PVC material has certain flexibility, so that the insulation layer is not easy to be damaged during the bending and installation of the wire.

Style Design: The overall style is a round wire with a smooth and flat surface. This design is not only convenient for the storage and laying of the wire but also can reduce friction with other objects during wiring, protecting the insulation layer. The multi-strand Stranded Conductor structure makes the wire look more exquisite, and also improves its flexibility and tensile resistance, facilitating its use in various complex wiring environments.

Color Options: Multiple color options such as red, blue, yellow, and green are available. Different colors correspond to different electrical functions. Red and blue are usually used for phase wires, blue can also be used as a neutral wire, and yellow and green are mostly used for Ground Wires. The distinction of colors is convenient for construction personnel to quickly identify during wiring, reducing the risk of misoperation and improving construction efficiency and safety.

Copper Wire Drawing: First, high-purity electrolytic copper ingots are made into copper rods through heating, rolling, and other processes, and then the copper rods are drawn into fine copper wires of the required diameter through a wire drawing machine. During the drawing process, it is necessary to strictly control the drawing speed and tension to ensure that the diameter of the copper wire is uniform, the surface is smooth, and defects such as cracks and burrs are avoided. For wires of different specifications, the diameter of the drawn copper wire is different to meet the corresponding conductor structure requirements.

Stranding Process: A number of drawn copper wires are stranded according to a certain stranding direction and pitch to form a conductor. During stranding, it is necessary to ensure that each copper wire is evenly stressed and tightly stranded to improve the mechanical strength and electrical conductivity of the conductor. The size of the stranding pitch will affect the flexibility and tensile resistance of the conductor, which needs to be accurately adjusted according to different specifications to ensure that the wire has good performance during use.

Insulation Layer Extrusion: An extruder is used to evenly coat high-quality PVC material on the surface of the stranded conductor to form an insulation layer. During the extrusion process, it is necessary to strictly control the extrusion temperature, speed, and pressure. Excessively high temperature will cause the decomposition of PVC material, affecting the insulation performance; excessively low temperature will make the insulation layer not closely combined with the conductor. Appropriate speed and pressure can ensure that the insulation layer has uniform thickness, smooth surface, and is closely combined with the conductor, ensuring the insulation effect.

Cooling and Solidification: The wire with the extruded insulation layer needs to be cooled through a cooling water tank to make the PVC material solidify quickly and shape the shape and performance of the insulation layer. During the cooling process, it is necessary to control the water temperature and cooling time. Excessively low water temperature will cause cracks on the surface of the insulation layer, and excessively high water temperature will affect the solidification effect. Appropriate cooling conditions can ensure the stable quality of the insulation layer and improve the performance of the wire.

Quality Inspection: Strict quality inspection is carried out in all links of the production process. In the copper wire drawing stage, the diameter, purity, and surface quality of the copper wire are inspected; in the stranding process stage, the stranding quality, number of strands, and diameter of the conductor are checked; in the insulation layer extrusion stage, the thickness, uniformity, and surface quality of the insulation layer are detected. The finished wire also needs to undergo overall performance tests, including conductor resistance test, insulation withstand voltage test, low-temperature bending test, aging test, etc., to ensure that each batch of products meets international safety standards and related quality requirements.

Packaging Method: For the convenience of transportation and storage, all three specifications of wires adopt a roll packaging method. The length of each roll of wire is usually 100 meters, and different lengths such as 50 meters and 200 meters can also be customized according to the special requirements of customers. When rolling, the wire is neatly wound on a paper or plastic reel. The size of the reel is designed according to the length and diameter of the wire to ensure that the wire will not be excessively squeezed or stretched during winding, thus protecting the performance of the wire.

Packaging Materials: The reel is made of high-strength paper or plastic materials. Paper reels have low cost, are easy to recycle, and are more environmentally friendly, suitable for customers with requirements on packaging costs; plastic reels have better corrosion resistance and durability, can protect the wire in humid or harsh environments, and are suitable for situations with poor transportation and storage conditions. The outer layer of the wire is also wrapped with a layer of plastic film, which plays the role of moisture-proof, dust-proof, and protecting the insulation layer, avoiding contamination and damage to the wire during transportation and storage.

Identification Information: Each reel is affixed with a clear identification label, which contains information such as the product name, specification parameters (such as wire diameter, rated voltage, color, etc.), execution standards, production batch number, production date, shelf life, manufacturer's name, address, and contact information. This information is convenient for users to quickly identify the basic situation of the product and is also conducive to the traceability of product quality. In case of problems, the production batch and related information can be found in time for handling.

Transportation Methods: According to the order quantity and the customer's geographical location, different transportation methods can be selected. For small batch orders, express transportation is usually used, such as well-known express companies like SF Express, YTO Express, and ZTO Express. Express transportation is fast and can deliver products to customers in a short time, suitable for customers who are close or have high requirements on delivery time. For large batch orders, logistics transportation is adopted, such as large logistics companies like Deppon Logistics and Tiandi Huayu, which transport goods to the destination by road. Logistics transportation has relatively low cost and is suitable for long-distance and large-batch cargo transportation.

Transportation Precautions: During transportation, the wire should be avoided from severe collision, extrusion, exposure to the sun, and rain. A certain distance should be maintained between reels to prevent mutual friction from damaging the insulation layer. For long-distance transportation, the goods should be fixed, and the reels should be fixed with ropes or pallets to prevent displacement or falling during transportation. At the same time, the transport vehicle should be kept clean and dry to avoid contamination of the wire by dust, oil, etc., which may affect product quality. During loading and unloading, handle with care to avoid damage to the wire caused by rough handling.
