The stranding pitch of 10mm² and 16mm² is approximately 15-20mm, and that of 25mm² and 35mm² is about 20-25mm to ensure the structural stability and Flexibility of the conductor.

Identification Parameters: The width ratio of the green-yellow two-color identification is 1:1, and the length of each color segment alternates between 50-100mm. The identification is printed with special ink, with a thickness of approximately 0.05-0.1mm, which has strong adhesion and can remain clear after multiple frictions and bendings.

Length Specification: The conventional lengths include 50 meters, 100 meters, 200 meters, 300 meters, 500 meters, etc. It can also be customized according to the special needs of customers, with a maximum customization length of 1000 meters. The length error is controlled within ±0.5% to ensure that the actual length is basically consistent with the marked length.

Weight Parameters: The weight per meter of the 10mm² cable is approximately 0.09kg, the 16mm² is about 0.14kg, the 25mm² is around 0.22kg, and the 35mm² is roughly 0.31kg. The weight of the whole roll of cable varies according to the length. For example, a 100-meter-long 10mm² cable weighs about 9kg, and a 100-meter-long 35mm² cable weighs about 31kg.

Household and Small Commercial Places: The 10mm² and 16mm² cables are widely used in household circuits and can be used for the safety grounding of high-power household appliances such as air conditioners, refrigerators, and washing machines. They can timely conduct the leakage current of the appliance shell to the ground to avoid human electric shock. In small commercial places, such as convenience stores and small restaurants, they can be used for grounding lighting equipment and cash register systems to ensure electrical safety. For example, in convenience stores, equipment such as refrigerators and microwave ovens are grounded through this cable, which can effectively prevent safety accidents caused by equipment leakage.

Industrial Production Field: The 25mm² and 35mm² cables are suitable for grounding medium and large industrial equipment, such as machine tools, cranes, and production lines. These devices may generate large induced currents or leakage currents during operation. This cable can quickly conduct them away, protecting the normal operation of the equipment and the safety of operators. In the power distribution system of factories, this cable can also be used for grounding to ensure the stable operation of the power distribution system and reduce power outages caused by poor grounding.

Public Building Facilities: In public buildings such as office buildings, shopping malls, and hospitals, 25mm² and 35mm² cables can be used for lightning protection grounding and power distribution system grounding. In thunderstorm weather, the lightning protection grounding system conducts lightning current to the ground through this cable to prevent buildings and internal equipment from being damaged by lightning strikes. The grounding of the power distribution system can ensure the stability of power supply and prevent voltage fluctuations from affecting large equipment such as elevators and central air conditioners.

Outdoor Engineering Scenarios: Because the bare copper conductor has certain corrosion resistance after special treatment, this series of cables can be used for grounding in outdoor projects, such as grounding of street lamps, traffic lights, and outdoor billboards. In humid and rainy outdoor environments, it can maintain stable grounding performance, ensuring the normal operation of outdoor equipment and the safety of pedestrians.

Conductor Material: High-purity electrolytic copper is used as the conductor material, with a purity of more than 99.95%. High-purity copper has excellent conductivity, with a conductivity of more than 100% IACS (International Annealed Copper Standard), which can effectively reduce losses during current transmission. At the same time, electrolytic copper has good ductility and toughness, which is convenient for stranding processing and ensures the structural stability of the conductor.

Identification Material: The green-yellow two-color identification uses special ink with strong weather resistance. This ink has good adhesion, wear resistance, and UV resistance, and is not easy to fade or fall off after long-term use in outdoor environments. The ink contains no harmful substances, meets environmental protection standards, and is harmless to the human body and the environment.

Style Design: The cable is cylindrical in shape, with a smooth surface and evenly distributed green-yellow two-color identification. According to different usage scenarios, different styles such as coiled and 盘装 can be provided. Coiled cables are convenient for manual handling and short-distance laying, while 盘装 ones are suitable for mechanical laying and long-distance use. The two ends of the cable can be processed according to customer needs, such as installing copper lugs and stripping wires, to facilitate connection with other equipment.

Copper Wire Drawing Process: High-purity electrolytic copper ingots are heated to a certain temperature and drawn into fine copper wires of the required diameter through a drawing die. During the drawing process, the drawing speed and die precision are strictly controlled to ensure that the copper wire diameter is uniform, the surface is smooth, and there are no scratches, cracks, or other defects. The drawn copper wire also needs to be annealed to eliminate internal stress and improve the flexibility and ductility of the copper wire.

Conductor Stranding Process: According to different cross-sectional area specifications, multiple fine copper wires are stranded according to the specified stranding method and pitch. During the stranding process, special stranding equipment is used to ensure that the copper wires are arranged neatly, the tension is uniform, and there are no loose strands, broken wires, or other phenomena. The Stranded Conductor needs to undergo appearance inspection and diameter measurement to ensure that it meets the specification requirements.

Identification Printing Process: The green-yellow two-color identification is printed on the surface of the stranded conductor using a roller printing process. Before printing, the surface of the conductor needs to be cleaned to remove oil, oxide layers, and other impurities to ensure the adhesion of the ink. During the printing process, the printing speed, pressure, and ink dosage are precisely controlled to ensure that the identification color is uniform, clear, and the position is accurate. After printing, the identification is dried to make the ink cure quickly.

Quality Inspection Process: Strict quality inspection is carried out in each link of production. After copper wire drawing, the diameter, tensile strength, elongation, and other parameters of the copper wire are tested; after conductor stranding, the diameter, cross-sectional area, DC resistance, and other parameters of the conductor are tested; after identification printing, the clarity, adhesion, and color uniformity of the identification are tested. The finished cable also needs to undergo pressure tests, insulation resistance tests (although it is bare copper, the overall performance needs to be tested), etc., to ensure that the product quality meets relevant standards.

Packaging Materials: High-strength plastic reels and moisture-proof paper are used as packaging materials. Plastic reels have the characteristics of compression resistance, drop resistance, and corrosion resistance, which can effectively protect the cable from damage during transportation and storage. Moisture-proof paper has good moisture-proof performance and can prevent the cable from being damp and oxidized in a humid environment. For long-length and heavy-weight cables, wooden pallets are also used for reinforced packaging to ensure stability during transportation.

Packaging Methods: According to the specifications and lengths of the cables, different packaging methods are adopted. Small-specification and short-length cables are usually packaged in coils with plastic reels. Each coil is wrapped with moisture-proof paper and then fixed with plastic film. Large-specification and long-length cables are packaged in coils with wooden pallets. The cable reels are fixed on the pallets and fastened with strapping to prevent the cable reels from rolling during transportation. The packaging clearly marks the product name, specification, length, production date, batch number, implementation standard, and other information.

Packaging Marks: The marks on the packaging are clear and standardized. In addition to basic product information, there are also warning marks such as "Handle with Care", "Moisture-Proof", and "Sun-Proof". The marks are printed with wear-resistant ink, which is not easy to fade and can be clearly seen in the entire circulation link, reminding transportation and storage personnel to pay attention to relevant matters.

Transportation Methods: According to the customer's geographical location and order quantity, appropriate transportation methods are selected. For short-distance transportation, road transportation is adopted, and van trucks can be chosen to prevent the cables from being exposed to the sun and rain during transportation. For long-distance transportation, railway transportation or water transportation can be used. These two transportation methods are relatively low in cost and suitable for large quantities of goods transportation. For emergency orders, air transportation can be adopted to ensure that the products are delivered to customers quickly.

Transportation Precautions: During transportation, cables should avoid severe collision, extrusion, exposure to the sun, and rain. When loading cables, they should be placed stably, avoid stacking too high, and the weight should be evenly distributed to prevent the transport vehicle from tilting. During transportation, drivers should drive carefully, avoid sudden braking, sharp turns, and other operations to reduce the shaking and collision of the cables. For bare Copper Cables, special attention should be paid to preventing the conductor surface from being scratched and corroded. During transportation, avoid contact with sharp objects and keep away from corrosive substances.
