I. Information Related to the Product Itself
(1) Specification Parameters
In terms of conductor cross-sectional area, common specifications are 120mm² and 240mm². The 120mm² cable is suitable for medium power load transmission scenarios, such as
Internal Wiring of some small and medium-sized industrial equipment; while the 240mm² cable can carry larger currents, and is mostly used in power transmission of large machinery and building electrical engineering with high power demand.
In addition to the conductor cross-sectional area, the number of strands and the diameter of single wires of the conductor are also important specification parameters. Taking the 120mm² RV-K flexible
Copper Electrical wire as an example, its conductor is usually made by stranding multiple fine
Copper Wires with a diameter of about 0.2-0.3mm, and the total number of strands can reach hundreds; the 240mm² cable has more strands, and the diameter of single wires will be slightly adjusted according to the actual situation. This design not only ensures the
Flexibility of the conductor but also meets the current-carrying requirements.
The outer diameter of the cable also varies with specifications. The outer diameter of the 120mm² RV-K flexible copper electrical wire is generally about 15-20mm, and that of the 240mm² is about 20-25mm. The outer diameter parameter is crucial for the planning of cable laying space, especially for installation in narrow spaces, where the outer diameter size of the cable needs to be accurately grasped.
In addition, the rated voltage of the cable is usually 0.6/1kV, which enables it to be widely used in low-voltage electrical systems. At the same time, its operating temperature range is relatively wide, and it can work normally in an ambient temperature range of -40℃ to 90℃. The short-term overload temperature can even reach 130℃, which can adapt to temperature changes in different regions and working conditions.
(2) Characteristic Applications
RV-K flexible copper electrical wire, with its unique performance advantages, has distinctive applications in many fields, providing reliable guarantee for the stable operation of various electrical systems.
In the internal wiring of industrial equipment, RV-K flexible copper electrical wire performs excellently. The internal structure of industrial equipment is complex, and the wiring space is often very narrow. In addition, vibration may occur during the operation of the equipment. The excellent flexibility of the cable enables it to easily 穿梭 between various components inside the equipment, adapting to complex wiring paths. At the same time, its good anti-vibration performance can ensure the stability of line connection during long-term operation of the equipment, reduce line faults caused by vibration, and ensure the normal production of industrial equipment.
Line connection in building electrical engineering is also an important application scenario. In construction projects, electrical lines need to be laid in a concealed way, such as inside walls and under floors. The flexibility of RV-K flexible copper electrical wire is convenient for construction personnel to perform bending and pipe 穿 ing operations, improving construction efficiency. Moreover, its XLPE insulation layer has good aging resistance and flame retardancy, which can maintain stable performance during the long-term use of the building, reduce potential safety hazards such as fire, and ensure the safe operation of the building electrical system.
Power transmission of large machinery is also inseparable from RV-K flexible copper electrical wire. Large machinery such as cranes and excavators have frequent relative movements between components during operation, which have extremely high requirements on the flexibility and bending resistance of the cable. The cable can withstand frequent bending and stretching, and will not break or have insulation layer damage due to mechanical movement, ensuring that power can be continuously and stably transmitted to various working components, and ensuring the normal operation of large machinery.
In addition, RV-K flexible copper electrical wire is also used in some special electrical equipment, such as medical equipment and precision instruments. These equipment have strict requirements on the accuracy and stability of electrical connections. The high-purity
Copper Conductor of the cable can reduce the loss of signal transmission, ensure the accurate operation of the equipment, and its flexible design will not interfere with the precision structure of the equipment.
(3) Material Styles
RV-K flexible copper electrical wire fully considers performance and usage requirements in material selection and style design, enabling it to play an excellent role in various environments.
The
Conductor Material is high-purity electrolytic copper, with a purity of more than 99.95%. High-purity copper has excellent electrical conductivity, which can effectively reduce resistance loss during current transmission and improve the efficiency of electrical energy utilization. At the same time, electrolytic copper has good ductility and toughness, which is convenient for processing into fine copper wires for stranding, ensuring the flexibility of the conductor.
The insulation layer material is cross-linked polyethylene (XLPE), which is a specially treated polymer material. XLPE material has excellent electrical insulation performance, with high volume resistivity and low dielectric loss, which can effectively prevent current leakage, ensure the insulation strength of the cable, and improve the safety of power transmission. Compared with traditional polyvinyl chloride (PVC)
Insulation Materials, XLPE has better temperature resistance, can maintain stable insulation performance in higher temperature environments, and has strong anti-aging performance, which greatly prolongs the service life of the cable.
In terms of style, RV-K flexible copper electrical wire is a single-
Core Cable style. The single-core design makes its structure relatively simple, with better flexibility, and more convenient for laying and installation in complex environments. The appearance of the cable is usually a black or gray XLPE insulation layer with a smooth surface, which is easy to identify and lay. In addition, according to different usage needs, insulation layers of different colors can also be provided to distinguish different circuits, facilitating the installation and maintenance of lines.
(4) Production Process
The production process of RV-K flexible copper electrical wire adopts advanced process technology and goes through multiple strict procedures to ensure that the product quality meets relevant standards and requirements.
The manufacture of the conductor is the first step in production. First, high-purity electrolytic copper rods are subjected to wire drawing treatment, and through continuous stretching process, the copper rods are drawn into copper wires with small diameters. During the wire drawing process, it is necessary to accurately control the size of the wire drawing die and the wire drawing speed to ensure that the diameter of the copper wire is uniform, and at the same time avoid damage to the copper wire due to excessive stretching. After wire drawing, multiple copper wires are stranded according to a certain stranding method. During stranding, the tension of each strand of copper wire must be uniform to form a tight and stable conductor structure, enhancing the flexibility and mechanical strength of the conductor.
The extrusion of the insulation layer is one of the key processes. Using special extrusion equipment, XLPE material is heated and melted, then evenly extruded on the surface of the
Stranded Copper Conductor to form an insulation layer. During the extrusion process, it is necessary to strictly control the extrusion temperature, pressure and speed to ensure that the insulation layer has uniform thickness, smooth surface, and is closely combined with the conductor without defects such as bubbles and impurities. The extruded
Insulated Wire core needs to undergo cross-linking treatment, usually by dry cross-linking or warm water cross-linking, so that the XLPE molecules form a stable three-dimensional network structure, thereby endowing the insulation layer with excellent electrical and mechanical properties.
After the cross-linking treatment, the cable is cooled and shaped to solidify the insulation layer. During the cooling process, the cooling rate must be controlled to avoid cracking of the insulation layer due to uneven cooling. The cooled cable also needs to undergo a series of quality inspections, such as insulation thickness inspection, outer diameter inspection, breakdown voltage test, etc., to ensure that the quality of the insulation layer meets the requirements.
Finally, the qualified cables are rewound and packaged. During the rewinding process, the tension of the cable must be kept uniform to avoid twisting and knotting of the cable, ensuring that the appearance of the cable is neat and beautiful, and easy to transport and store.
II. General Product Information
(1) Packaging
The packaging design of RV-K flexible copper electrical wire fully considers the protection needs of the product, ensuring that it is not damaged during transportation, storage and handling, and also facilitating customers' access and management.
Usually, the cable is packaged in reels. There are two types of reels: wooden reels and plastic reels. Wooden reels have the characteristics of high strength and large load-bearing capacity, and are suitable for packaging long-length and large-specification cables, which can effectively protect the cables from extrusion and collision during transportation. Plastic reels have the advantages of light weight and corrosion resistance, and are mostly used for packaging short-length and small-specification cables, and can be recycled, which is more environmentally friendly.
When the cable is wound on the reel, it is wound according to a certain tension to make the cable arranged neatly and tightly, avoiding loosening and mutual friction during transportation, and protecting the insulation layer from damage. Both sides of the reel are provided with baffles, and the height of the baffles is higher than the winding height of the cable, which can further prevent the cable from slipping off the reel.
On the surface of the reel, clear product information is marked, including product name, model specification, conductor cross-sectional area, length, rated voltage, production date, manufacturer, etc., which is convenient for customers to identify and check during receipt and use. For exported products, corresponding international standards and certification information are also marked.
In addition, to prevent the cable from getting damp and polluted during storage, the outside of the reel is wrapped with a layer of plastic film, which has good moisture-proof and dust-proof performance and can effectively protect the cable from the external environment. For some customers with special requirements, other packaging methods such as wooden boxes can also be used according to their needs.

During transportation, the cables need to be properly fixed. Place the reels stably in the transport vehicle or container, and use ropes, steel belts, etc. to fix the reels firmly to prevent the reels from rolling and colliding due to vehicle bumps and turns during transportation, causing damage to the cables. For multi-layer stacked reels, buffer pads should be placed between layers to avoid mutual extrusion between reels.
During transportation, attention should be paid to avoiding the cables from being exposed to direct sunlight, rain, snow, and extreme environments such as high and low temperatures. In case of bad weather, the transport vehicles need to be covered and protected to ensure that the storage environment of the cables meets the requirements. At the same time, transport personnel should regularly check the packaging of the cables and deal with problems in a timely manner.
In addition, traffic rules must be observed during transportation to ensure transportation safety.
