Cable U-1000 Rvfv Arvfv Vvfv is a versatile multi-specification aluminum-copper composite cable that performs excellently in various scenarios such as industrial power distribution, building power transmission, and underground laying. The following will provide a detailed introduction to this cable from two dimensions: the product itself and general product information.
From the Perspective of the Product Itself
Specifications and Parameters
Cable U-1000 Rvfv Arvfv Vvfv is meticulously designed in terms of specifications and parameters to meet the power transmission needs of different scenarios.
The cable has a wide range of cross-sectional specifications, including 4X25mm², 4X95mm², etc. For the 4X25mm² cable, the diameter of each conductor is approximately 2.8mm, and the overall outer diameter of the cable is about 25mm; for the 4X95mm² cable, the diameter of each conductor is about 5.4mm, and the overall outer diameter is approximately 40mm. Different cross-sectional specifications correspond to different current-carrying capacities. The 4X25mm² specification has a current-carrying capacity of about 80-100A, and the 4X95mm² specification has a current-carrying capacity of 180-220A, enabling them to adapt to low-to-medium power and high-power power transmission tasks respectively.
The rated voltage of the cable is 1000V, and this voltage level makes it suitable for low-voltage distribution systems, which can meet the power needs of most equipment in industrial, construction and other fields. At the same time, it has a wide operating temperature range and can operate normally between -40℃ and 105℃. Whether in cold northern regions or high-temperature industrial workshops, it can maintain stable performance.
In addition, the insulation thickness of the cable varies according to cross-sectional specifications. The insulation thickness of the 4X25mm² specification is about 1.0mm, and that of the 4X95mm² specification is about 1.4mm. Sufficient insulation thickness ensures the safety of the cable during power transmission and effectively prevents electric leakage. The thickness of the armor layer is 0.3-0.5mm, and the thickness of the outer
PVC Sheath is about 1.2mm. These parameters jointly guarantee the mechanical strength and protective performance of the cable.
Characteristic Applications
Cable U-1000 Rvfv Arvfv Vvfv has characteristic applications in many fields due to its unique performance.
The 4X25mm² cable, with its moderate current-carrying capacity, is suitable for power supply of small and medium-sized industrial equipment. For example, in an injection molding workshop, when multiple injection molding machines are running at the same time, stable power supply is required, and this specification of cable can meet its power needs and ensure the normal operation of the injection molding machines. In terms of fan power supply, whether it is a ventilation fan in a factory or a fan in a central air conditioning system, the 4X25mm² cable can provide reliable power transmission. In high-rise buildings, it is often used as a branch line to distribute power from the main distribution box to the distribution boxes on each floor, supplying power to lighting, sockets and other equipment in the floor.
The 4X95mm² cable is suitable for large-capacity power transmission scenarios. Large production lines have many equipment and huge power, so they have a great demand for electricity. This specification of cable can take on the task of supplying power to large production lines and ensure the continuous operation of the production lines. In the substation outgoing line link, it is necessary to transmit power from the substation to various power consumption areas, and the large-capacity transmission capacity of the 4X95mm² cable makes it a suitable choice. Urban power grid branches are responsible for distributing power from the main grid to various communities, commercial areas, etc. This specification of cable can meet the power transmission needs of urban power grid branches and ensure the stability of residential and commercial power consumption.
In addition to the above scenarios, this cable is also suitable for use in complex environments such as industrial plants, underground direct burial, and tunnel projects. In industrial plants, there are mechanical vibrations, oil pollution and other situations. The armor layer and PVC sheath of the cable can resist the impact of these adverse factors and ensure stable power transmission. When directly buried underground, the cable needs to withstand soil pressure and groundwater erosion, and its good protective performance enables it to work reliably for a long time in this environment. In tunnel projects, the space is limited and there may be various dust and moisture. The cable can adapt to such an environment and ensure that the power supply is not affected.
Material Styles
Cable U-1000 Rvfv Arvfv Vvfv has been carefully considered in material selection and style design to ensure high quality and practicality of the product.
The conductor adopts an aluminum-copper composite structure, with a high-purity
Aluminum Conductor as the core, with a purity of more than 99.7%, and a high-conductivity copper layer coated on the outer layer, with a copper layer purity of 99.9%. This composite structure combines the advantages of aluminum and copper. Aluminum has a low density, which makes the cable weight 40% lighter than
Pure Copper Cables, reducing the difficulty of transportation and installation; copper has excellent conductivity, and the outer copper layer makes the cable conductivity reach more than 85% IACS, effectively reducing losses during power transmission.
The insulation layer is made of XLPE (cross-linked polyethylene) material. After cross-linking treatment, the molecular structure of this material forms a three-dimensional network structure, which greatly improves its heat resistance, aging resistance and mechanical strength. XLPE material has a temperature resistance range of -40℃ to 105℃, and can maintain stable insulation performance in various extreme temperature environments. The insulation resistance is stable above 1000MΩ, which can effectively prevent current leakage and ensure electrical safety. At the same time, it also has good chemical corrosion resistance and can resist erosion from harsh environments such as moisture, acids and alkalis.
The armor layer is made of 0.3-0.5mm thick hot-dip galvanized
Steel Tape (Sta). The hot-dip galvanizing treatment forms a uniform and dense zinc layer on the surface of the steel tape, which can effectively prevent the steel tape from being corroded and prolong the service life of the armor layer. Through the spiral winding process, the steel tape is tightly wrapped around the outer layer of the cable to form a solid protective layer, making the cable's lateral pressure resistance reach 10kN/m and impact resistance 5kN, which can withstand external extrusion and collision.
The outer PVC (polyvinyl chloride) sheath has good weather resistance and mechanical properties, and can withstand ultraviolet radiation, oil pollution and mechanical wear. PVC material also has certain flame retardant properties, which can delay the spread of fire in case of fire and improve the safety of the cable.
In terms of style, the cable has a
Multi-Core structure, with
4 Conductors twisted together, and the whole is round. The color of the cable is usually black, which can absorb heat, reduce the impact of direct sunlight on the cable, and also look simple and elegant. The surface of the cable is smooth, which is convenient for passing through pipes and cable trays during laying.
Production Process
The production process of Cable U-1000 Rvfv Arvfv Vvfv is exquisite, and each process is strictly controlled to ensure product quality.
The production of the conductor is the first step. First, high-purity aluminum ingots are made into aluminum rods through smelting, casting and other processes, and then the aluminum rods are drawn into
Aluminum Wires of the required diameter through a wire drawing machine. During the wire drawing process, the drawing speed and die size must be accurately controlled to ensure the uniform diameter of the
Aluminum Wires. Then, copper plating is performed on the surface of the aluminum wire, and high-purity copper is uniformly plated on the surface of the aluminum wire by electroplating process to form an aluminum-copper composite conductor. During copper plating, the thickness and uniformity of the copper layer must be controlled to ensure the conductivity of the conductor.
The extrusion of the insulation layer is one of the key processes. The XLPE material is heated to a molten state, and evenly coated on the surface of the conductor through an extruder. During the extrusion process, the extrusion temperature, pressure and speed must be strictly controlled to ensure that the insulation layer has uniform thickness, smooth surface, and no bubbles, impurities and other defects. After extrusion, the
Insulated Wire core is subjected to cross-linking treatment, usually using a dry cross-linking process. In a high-temperature and high-pressure environment, the XLPE molecules undergo a cross-linking reaction to form a three-dimensional network structure, thereby improving the performance of the insulation layer.
The armor layer is processed by a spiral winding process, and the hot-dip galvanized steel tape is wound on the outer layer of the insulated wire core at a certain angle and tension through special winding equipment. During the winding process, the overlap between the steel tapes must be uniform and tight to form a continuous protective layer. At the same time, the winding tension must be controlled to avoid the steel tape being too loose or too tight, which will affect the performance and
Flexibility of the cable.
Finally, the outer PVC sheath is extruded. The PVC material is heated and melted, and then coated on the outer layer of the armor layer through an extruder. During the extrusion process, it is necessary to ensure that the sheath has uniform thickness, is closely combined with the armor layer, and has no gaps. After extrusion, the cable is subjected to cooling, marking and other treatments, and the product model, specification, length, production date and other information are printed on the surface of the cable for easy identification and traceability.
During the production process, each process must undergo strict quality inspection. For example, the diameter, resistance and other parameters of the conductor must be sampled and tested; the thickness, insulation resistance, voltage withstand performance, etc. of the insulation layer must be fully tested; the winding quality of the armor layer and the thickness of the sheath must also be checked. Only cables that pass all inspection items can leave the factory to ensure stable and reliable product quality.
From the Perspective of General Product Information
Packaging
The packaging design of Cable U-1000 Rvfv Arvfv Vvfv fully considers various factors during transportation and storage to ensure that the cable is intact.
The cable is wrapped with moisture-proof kraft paper, which has good moisture-proof performance and can effectively block moisture in the air from entering the cable, preventing the cable from being damp and affecting the insulation performance. During the wrapping process, the kraft paper must be tightly wound on the surface of the cable to ensure that every part is fully protected.
The wrapped cable is wound on a galvanized iron reel. The galvanized iron reel is made of high-quality steel and has good corrosion resistance and mechanical strength after galvanizing treatment, which can bear the weight of the cable and the pressure during transportation. The size of the iron reel is designed according to the specification and length of the cable. Cables of 4X25mm² specification are usually wound on iron reels with a diameter of 800mm, and cables of 4X95mm² specification are wound on iron reels with a diameter of 1200mm to ensure that the cables can be wound neatly and avoid distortion and knotting.
The outer layer of the iron reel is also covered with a layer of wrapping film, which has good stretchability and sealing performance, and can tightly wrap the cable and the iron reel together, further enhancing the moisture-proof, dust-proof and pressure-proof performance of the packaging. At the same time, the wrapping film can also prevent the cable from falling off the iron reel during transportation, ensuring transportation safety.
In addition, a label will be pasted on the iron reel, indicating the cable's model, specification, length, rated voltage, production date, manufacturer and other information, which is convenient for customers to identify and manage during receipt and storage. For exported cables, the labels will also be marked with corresponding international standards and certification marks to meet the import requirements of different countries and regions.
Transportation
In order to ensure that Cable U-1000 Rvfv Arvfv Vvfv can be delivered to customers safely and timely, there are various flexible transportation methods, which are optimized according to actual conditions.
Land transportation is one of the commonly used transportation methods, suitable for medium and short-distance transportation. For large-volume cable orders, full vehicle transportation is usually adopted, that is, a truck only loads this cable, which can avoid mutual extrusion and collision between the cable and other goods, reducing the risk of damage. Full vehicle transportation also has the advantages of high transportation efficiency and fast arrival time, which can meet the urgent needs of customers. For small-volume orders, less-than-truckload transportation can be used, which 集中 loads multiple small batches of cables on a truck and transports them by means of loading, which can reduce transportation costs and is suitable for customers who are not particularly urgent about transportation time.
Maritime transportation is mainly suitable for long-distance transportation and export orders, with the characteristics of large transportation volume and low cost. During maritime transportation, the cables will be loaded in containers.
