(I) Specification Parameters
Cross - sectional Area Specifications
This wire has various cross - sectional area specifications such as 1.5mm², 2.5mm², 4mm², 6mm², and 10mm², which can meet the power transmission needs in different scenarios. The 1.5mm² wire is more common in household lighting and small socket circuits; the 2.5mm² is suitable for power supply of household appliances with slightly larger power; 4mm² and 6mm² can be used for residential main lines or small and medium - sized industrial equipment; 10mm² is mainly applied to large power equipment or main lines of distribution boxes.
Current - carrying Capacity
There are obvious differences in the current - carrying capacity of different cross - sectional areas, and it will adjust with the change of ambient temperature. At an ambient temperature of 30℃, the current - carrying capacity of 1.5mm² is about 14 - 20A; the current - carrying capacity of 2.5mm² reaches 20 - 25A; the current - carrying capacity of 4mm² is 25 - 32A; the current - carrying capacity of 6mm² is 32 - 40A; the current - carrying capacity of 10mm² can reach 40 - 60A. When the ambient temperature rises to 40℃, the current - carrying capacity of each specification will decrease by about 10% - 15%, because high temperature will affect the heat dissipation of the wire, and then affect its current - carrying capacity.
Conductor Structure
The conductor adopts a multi - strand stranded design, and the diameter of each
Copper Wire is only 0.1 - 0.3mm. The 1.5mm² wire is formed by stranding [X] copper wires, 2.5mm² by [X] strands, 4mm² by [X] strands, 6mm² by [X] strands, and 10mm² by [X] strands. This multi - strand stranded structure greatly enhances the
Flexibility of the wire, enabling it to bend freely in narrow spaces and complex wiring environments without breaking easily.

High - purity electrolytic copper has excellent conductivity, with a conductivity of more than 58MS/m, which can transmit current quickly and efficiently, reducing energy loss. At the same time, electrolytic copper has good ductility and toughness, which is convenient for processing into small copper wires for stranding, and is not easy to break during stranding, ensuring the overall quality and performance of the conductor.
Insulation Layer Material
The insulation layer is made of high - quality PVC material. PVC has good insulation performance, which can effectively insulate current and prevent electric leakage accidents. It also has certain chemical corrosion resistance, which can resist the erosion of oil stains, moisture and other substances, and prolong the service life of the wire. In addition, PVC material has good processing performance and is easy to be extruded into shape, which can produce uniform insulation layers according to the needs of wires of different specifications.
Style Design
The appearance of the wire is usually black or gray. These two colors are relatively calm and not easy to get dirty, making them suitable for use in various environments. The surface is smooth and flat without obvious defects, which is not only beautiful but also can reduce the resistance during pipe threading, facilitating installation. The surface of the wire is printed with clear identification information such as specifications, standards, and manufacturers, which is convenient for construction personnel to identify and check during installation to avoid misuse.
(IV) Production Process
Conductor Manufacturing
First, high - purity electrolytic copper raw materials are made into copper rods through smelting, ingot casting and other processes. Then, the copper rod is drawn into copper wires with a diameter of 0.1 - 0.3mm through a wire drawing machine. During the wire drawing process, it is necessary to strictly control the drawing speed and temperature to ensure the quality and dimensional accuracy of the copper wire. The drawn copper wire should be annealed to eliminate internal stress and improve the flexibility and ductility of the copper wire. Finally, according to different cross - sectional area specifications, a corresponding number of copper wires are stranded according to a specific stranding method to form a multi - strand
Stranded Conductor. During the stranding process, it is necessary to ensure that the tension of each copper wire is uniform to ensure the stable structure and consistent conductivity of the conductor.
Insulation Layer Extrusion
PVC particles are added to the hopper of the extruder, heated and melted, and then evenly wrapped on the surface of the stranded conductor through an extrusion die to form the insulation layer. During the extrusion process, it is necessary to accurately control the extrusion temperature, speed and pressure to ensure that the insulation layer has a uniform thickness, a smooth surface, and is closely combined with the conductor. After the insulation layer is extruded, it is immediately cooled, usually by water cooling, to make the insulation layer solidify and shape quickly.
Quality Inspection
Strict quality inspection is required for each process during production. For the conductor, its diameter, DC resistance, tensile strength and other parameters should be tested to ensure compliance with relevant standards. For the insulation layer, its thickness, insulation resistance, voltage resistance performance, temperature resistance performance and other indicators should be tested to ensure the quality of the insulation layer. The finished wire also needs to undergo overall performance tests, such as bending resistance test, aging resistance test, chemical corrosion resistance test, etc., to ensure the reliable quality of the wire.
Logo Printing
After the insulation layer is solidified, special printing equipment is used to print identification information such as specifications, standards, manufacturers, and production dates on the surface of the wire. The printing should be clear and firm, not easy to fall off, so as to facilitate identification and traceability.
II. General Product Information
(I) Packaging
Packaging Materials
Different packaging materials are used according to the specifications and lengths of the wires. For small - specification and short - length wires, plastic reels or cartons are usually used for packaging. Plastic reels are lightweight and low in cost, convenient for handling and storage; cartons can provide better protection to prevent the wires from being squeezed and collided during transportation. For large - specification and long - length wires, wooden or steel reels are generally used for packaging. Wooden reels and steel reels have high strength and large load - bearing capacity, suitable for long - distance transportation and large - quantity storage. In addition, all packaging materials have certain moisture - proof and dust - proof properties to protect the wires from the influence of the external environment.
Packaging Methods
The wires are neatly wound on reels or bobbins. During the winding process, it is necessary to control the tension to avoid the wires being too tight or too loose. Being too tight may cause the wire to deform or the insulation layer to be damaged; being too loose may cause the wire to loosen and rub against each other during transportation, resulting in surface wear. After winding, the wire is fixed on the reel or bobbin with packing belts or ropes to prevent the wire from sliding. For wires packaged with reels, labels are pasted on the side of the reels, indicating the product name, specification, length, production date, manufacturer and other information.
Packaging Marks
In addition to product labels, packaging is also marked with some necessary signs, such as "Do Not Press Heavily", "Moisture - Proof", "Avoid Sun Exposure", "Handle with Care", etc., to remind transportation and storage personnel to operate correctly and avoid damage to the wires. For exported products, corresponding certification marks and foreign language descriptions will be marked according to the requirements of the destination country or region.
(II) Transportation
Transportation Methods
According to the transportation distance, quantity and customer requirements, different transportation methods can be selected. Short - distance transportation generally uses automobile transportation, which has high flexibility and can directly deliver goods to the customer's designated location, suitable for small - batch and urgent orders. Long - distance transportation can choose railway transportation or waterway transportation. Railway transportation has large transportation capacity, fast speed and relatively low cost, suitable for transporting large quantities of goods; waterway transportation has low cost but long transportation time, suitable for large quantities of goods that do not require high transportation time. For international orders, sea or air transportation can be used. Sea transportation is suitable for large quantities of goods, and air transportation is suitable for urgent and small - batch orders.
Transportation Precautions
During transportation, it is necessary to ensure that the packaging of the wire is intact to prevent the wire from being squeezed, collided, exposed to rain and sunlight. For wires packaged with reels, the reels should be kept stable to prevent tipping. During loading and unloading, special hoisting equipment such as cranes and forklifts should be used.
