RV Flexible Copper Cable 1.5-6mm² - 450/750V, PVC Insulated

Cross-sectional Size: The cross-sectional size of this cable ranges from 1.5mm² to 6mm². This range is determined based on in-depth research on the power demand of numerous small and medium-sized mobile devices. The 1.5mm² cable is relatively slender, suitable for small devices with strict restrictions on cable thickness; while the 6mm² cable can handle mobile devices with larger power, forming a complete specification system to meet the power transmission needs of devices with different powers. Cables of different cross-sectional sizes have obvious differences in appearance. The larger the cross-section, the thicker the outer diameter of the cable, allowing users to quickly identify its specification through visual observation.

Rated Voltage: The rated voltage is 450/750V, which determines the cable's ability to withstand voltage during power transmission. 450V is applicable to some low-voltage fixed connection scenarios, while 750V can meet the connection needs of mobile devices with higher voltage requirements, making it applicable in a wider range of electrical systems. This voltage level complies with relevant international and domestic electrical standards, ensuring the safety and compatibility of the cable during use.

Current-carrying Capacity: Current-carrying capacity is a key parameter for measuring the cable's ability to transmit current, and there are significant differences in current-carrying capacity among cables of different cross-sections. At an ambient temperature of 30℃, the current-carrying capacity of a 1.5mm² cable is approximately 12-18A, which can meet the needs of Internal Wiring of small household appliances such as vacuum cleaners and microwave ovens, as well as power leads of small electric tools; the current-carrying capacity of a 2.5mm² cable is about 18-25A, suitable for connection lines of office equipment such as printers and projectors, and temporary wiring of stage lighting equipment; the current-carrying capacity of a 4mm² cable is around 25-35A, which can be used for connecting some mobile devices with slightly larger power; the current-carrying capacity of a 6mm² cable is roughly 35-45A, which can meet the needs of flexible connection of small industrial robots, automated production lines, and lead-out lines of mobile distribution boxes. It should be noted that the current-carrying capacity in actual use will be affected by the laying environment. For example, conduit laying will deteriorate the heat dissipation conditions, and the current-carrying capacity needs to be reduced accordingly; when the ambient temperature rises, the current-carrying capacity of the cable will also decrease. Therefore, when selecting a cable, it is necessary to comprehensively consider the equipment power and laying environment to ensure the safe operation of the cable.

Bending Performance Parameters: One of the core advantages of this cable is its excellent bending performance, with a minimum bending radius as low as 4 times the outer diameter of the cable, which is far superior to ordinary fixed-laying cables. This means that the cable can flexibly bend in narrow spaces and adapt to various complex installation environments. After testing, after 10,000 repeated bendings (bending angle 90°, frequency 1 time/second), the conductor breakage rate is less than 0.1%, and the insulation layer has no cracking, fully demonstrating its excellent bending durability.

Insulation Performance Parameters: The thickness of the insulation layer is strictly controlled between 0.5-1.0mm, and increases with the increase of the cross-section, to ensure reliable insulation protection under different cross-sections. The cable has passed the 1500V voltage withstand test (no breakdown for 1 minute), and the insulation resistance is ≥100MΩ・km. These parameters ensure that the cable will not have faults such as electric leakage and short circuit under the rated voltage, effectively ensuring electrical safety.

Commercial Scenarios:

Industrial Scenarios:

Conductor Material: The conductor of RV flexible copper cable is made of high-purity electrolytic copper with a purity of more than 99.95%. High-purity copper has excellent electrical conductivity, which can reduce energy loss during current transmission and improve power transmission efficiency. At the same time, electrolytic copper has good ductility and toughness, which enables the Copper Wire to be drawn into extremely fine specifications (the diameter of a single copper wire is usually less than 0.2mm), laying the foundation for the multi-strand twisting process and ensuring the flexibility of the cable.

Insulation Layer Material: The insulation layer is made of high-elastic polyvinyl chloride (PVC) material, which has a higher plasticizer content compared with ordinary PVC. The increase of plasticizer greatly improves the flexibility of PVC material, endowing the insulation layer with excellent bending performance and aging resistance. This high-elastic PVC material also has good electrical insulation performance, which can effectively prevent current leakage and ensure that the insulation resistance and voltage withstand strength of the cable meet the standard requirements. In addition, this material has good oil resistance and chemical corrosion resistance, and can be used in environments with oil stains and slight corrosive gases, expanding the application range of the cable. At the same time, its flame retardant grade reaches UL94 V-0 standard, which can self-extinguish quickly when exposed to open fire, reducing the risk of fire spread and improving the safety of the cable.

Style: RV flexible copper cable is a round cable, which has many advantages in the production, laying and use processes. The circular structure makes the thickness of the cable's insulation layer uniform, ensuring consistent insulation performance in all directions, and avoiding local insulation weakness caused by irregular shapes. In practical applications, round cables are convenient for pipe laying and bending, and can adapt to various complex installation environments. In addition, the round style is also convenient for winding and storing cables, reducing the occupation of storage space.

Fine Wire Drawing: First, high-purity electrolytic copper ingots are smelted, and then drawn into extremely fine copper wires with a single strand diameter of less than 0.2mm through a wire drawing machine. During the wire drawing process, strict control is exercised over the drawing speed, temperature, and mold precision, with the drawing precision controlled within ±0.002mm to ensure that each strand of copper wire has a uniform diameter and a smooth surface. This can ensure consistent conductivity of the copper wires and prepare for the subsequent twisting process.

Layered Twisting: The "concentric layered" twisting process is adopted to twist multiple strands of extremely fine copper wires together to form a conductor. During twisting, the twisting direction of the outer copper wires is opposite to that of the inner layer. This process can offset the stress generated during twisting, greatly improving the flexibility of the conductor. During the twisting process, it is necessary to accurately control the tension of each strand of copper wire to ensure that the twisted conductor has a stable and round structure, avoiding looseness or distortion.

Continuous Extrusion: The insulation layer is extruded using special flexible PVC particles, and the insulation layer is wrapped around the conductor through a continuous extrusion process. During the extrusion process, it is necessary to accurately control the extrusion temperature, speed, and pressure to ensure that the thickness of the insulation layer is uniform (with a deviation within 0.05mm). At the same time, it is necessary to ensure that the insulation layer is tightly combined with the conductor without defects such as bubbles and wrinkles, ensuring the structural stability and insulation performance of the cable.

Cooling and Solidification: The cable after extruding the insulation layer immediately enters the cooling water tank for cooling, so that the PVC Insulation layer can be quickly solidified and formed. The cooling water temperature needs to be strictly controlled to avoid affecting the performance of the insulation layer due to too fast or too slow cooling speed. An appropriate cooling speed can reduce the internal stress of the insulation layer and improve its flexibility and aging resistance.

Quality Inspection: Each batch of products undergoes strict quality inspection, including 20 indicators such as conductor resistance, insulation thickness, voltage withstand strength, insulation resistance, and bending resistance. Only products that meet all the indicators of GB/T 5023.5-2008 "Polyvinyl Chloride Insulated Cables with Rated Voltage up to 450/750V - Part 5: Flexible Cables (Flexible Wires)" can leave the factory, ensuring the quality reliability of the products.

Printing Identification: Information such as product model, specification, rated voltage, manufacturer, and production date is printed on the surface of the cable's insulation layer. Special printing equipment is used for printing to ensure that the handwriting is clear, firm, and not easy to fall off, facilitating users to identify and trace product information.

Packaging Materials: Different packaging materials are used according to the length and cross-sectional size of the cable. For short-length cables (such as within 100 meters), plastic reels are usually used for packaging. Plastic reels have the advantages of light weight, low cost, and corrosion resistance, and are convenient for users to carry and use. For long-length cables (such as 500 meters, 1000 meters), wooden reels are used for packaging. Wooden reels have high strength and stability, can bear the weight of the cable, prevent deformation due to extrusion during transportation and storage, and better protect the cable.

Packaging Method: The cable is neatly wound on the reel or spool, and the tension is strictly controlled during the winding process to ensure that the cable is arranged neatly, without twisting or knotting. After winding, the reel or spool is wrapped with moisture-proof and wear-resistant plastic film as a whole to prevent the cable from being damaged by dust, moisture, and mechanical damage during transportation and storage. For wooden reels, protective devices are added to the edges to avoid collision damage during handling.

Packaging Marking: Clear marks are printed on the obvious position of the package, including product name, model, specification, length, rated voltage, production batch number, production date, implementation standard, manufacturer name, and contact information. These marks not only facilitate users to quickly identify the product but also provide a basis for product traceability.
