I. Product - related Information
(I) Specification Parameters
The specification parameters of the Arvfv aluminium core Power Cable are an important basis for its performance and applicable scenarios. Each parameter is carefully designed to meet the basic needs of power transmission. This cable has two core specifications, namely 4×70mm² and 4c×95mm². 4×70mm² means that the cable contains 4 Aluminium Conductors with a cross - sectional area of 70mm². This conductor configuration can balance the current - carrying capacity and cost to a certain extent, and is suitable for medium - power power transmission scenarios. 4c×95mm² indicates that it contains 4 aluminium conductors with a cross - sectional area of 95mm². The larger cross - section makes its current - carrying capacity better, and it can meet the power demand with relatively high power, such as the power supply of small and medium - sized factories. In terms of rated voltage, the cable is 0.6/1kV. This voltage level enables it to be adapted to low - voltage distribution systems. 0.6kV is the phase voltage and 1kV is the line voltage. This design allows the cable to stably transmit power in the low - voltage power grid and reduce the impact of voltage fluctuations on electrical equipment. It can be well adapted to both the power distribution of residential communities in cities and the centralized power supply in rural areas.
In terms of overall structural dimensions, in addition to the conductor specifications, the outer diameter of the cable is reasonably designed according to the conductor size and outer structure. The superposition of the Steel Tape armouring, XLPE insulation layer and outer sheath enables the cable to have sufficient mechanical strength without being excessively bulky, which is convenient for laying in different environments. At the same time, the bending radius of the cable also has a clear standard, which can meet the bending requirements in the conventional laying process and avoid damage to the internal structure due to excessive bending.
(II) Characteristic Uses
The characteristic uses of the Arvfv aluminium core power cable are closely related to its specifications, materials and structure, and it can play an important role in various power transmission scenarios.
Because it has two different conductor specifications, it can flexibly meet the power transmission needs of different powers. The 4×70mm² Cable can be used for branch transmission of urban distribution networks, transmitting power from substations to various residential communities or small commercial areas; it can also be used as a distribution line in industrial enterprises to provide power support for some small and medium - sized equipment. The 4c×95mm² cable can be used in high - power scenarios, such as connecting the main production equipment of small and medium - sized factories, or as the main distribution line of some large public facilities (such as gymnasiums and large shopping malls). Steel tape armouring is a major feature of this cable, which enables it to have strong resistance to mechanical damage, so it is suitable for laying environments that may have external mechanical impacts. For example, when laid directly underground, it can resist soil pressure and accidental collisions that may occur during construction; when laid in tunnels, it can cope with the friction and extrusion of other pipelines. At the same time, this armoured structure also allows the cable to maintain stable performance in humid, dusty and other environments. For example, the distribution lines in some factory workshops and underground parking lots can choose this cable.
In addition, the cable is suitable for 0.6/1kV low - voltage scenarios and has certain application space in the agricultural field. It can be used as the power supply line for rural irrigation equipment. When laid in fields, it can withstand certain wind, sun and slight mechanical collisions; it can also be used for power transformation in rural centralized residential areas to provide stable guarantee for villagers' daily electricity use.
(III) Material and Style
The choice of materials has a direct impact on the performance of the cable. The Arvfv aluminium core power cable fully considers practicality and reliability in material and style design.
The conductor is made of aluminium. Although aluminium is slightly inferior to copper in conductivity, it has the advantages of light weight and low cost. For cables laid over long distances, the light weight can reduce the laying difficulty and transportation cost; at the same time, the low cost can also save the overall expenditure in large - scale power projects. Moreover, the aluminium conductor used in this cable has been specially treated, with a smooth surface and extremely low impurity content, which effectively reduces energy loss during conduction.
The insulation layer is made of XLPE (cross - linked polyethylene). Compared with the traditional polyethylene insulation layer, this material has significantly improved heat resistance and aging resistance. It can maintain stable insulation performance at a relatively high temperature, up to about 90°C, avoiding insulation failure caused by cable heating during long - term operation. At the same time, the XLPE insulation layer has good chemical stability and has a certain resistance to corrosive substances such as acids and alkalis, which prolongs the service life of the cable.
The steel tape armouring layer is made of high - quality low - carbon steel tape, which has high mechanical strength after forming, welding and other processes. It can protect the internal conductors and insulation layer from external mechanical damage like a solid "armour". In addition, the steel tape armouring can also play a shielding role to a certain extent, reducing the impact of external electromagnetic interference on power transmission.
The outer sheath is usually made of materials with good weather resistance and wear resistance (such as PVC) to further enhance the protection ability of the cable. The sheath tightly wraps around the armouring layer to prevent moisture, dust, etc. from entering the cable, and at the same time resist external friction and chemical erosion.
In terms of style, the cable has a circular structure, which makes the force on the cable more uniform and less likely to have excessive local force during laying and use. The circular appearance is also convenient for cable winding, transportation and storage, and can better adapt to spaces such as pipes and trenches during laying.
(IV) Production Process
The production process of the Arvfv aluminium core power cable is rigorous and meticulous. Each link from raw material processing to finished product inspection has strict quality control to ensure the reliability of the product.
In the production of aluminium conductors, first, the aluminium rod is inspected for quality to ensure that its purity and mechanical properties meet the standards. Then, the aluminium rod is processed into an aluminium wire with the required diameter through a continuous extrusion process, which can ensure the dimensional accuracy and surface quality of the aluminium wire. Next, multiple Aluminium Wires are stranded in a specific way to form a conductor core. During the stranding process, the stranding pitch should be well controlled to ensure the roundness and Flexibility of the conductor, and at the same time reduce the stress when the conductor is bent. The extrusion of the XLPE insulation layer is one of the key processes. First, the XLPE particles are dried to remove moisture to avoid bubbles in the insulation layer. Then, the dried particles are added to the extruder, melted at high temperature and evenly wrapped around the conductor through a mould. During the extrusion process, the temperature, pressure and extrusion speed must be accurately controlled to ensure that the insulation layer has a uniform thickness and a smooth surface. After extrusion, the insulation layer is cross - linked. By heating, the XLPE molecules form a three - dimensional network structure, thereby improving its heat resistance and mechanical strength.
The steel tape armouring process requires pre - treatment of low - carbon steel tape, such as derusting and painting, to enhance its corrosion resistance. Then, the steel tape is wound around the insulation layer at a certain angle through an armouring machine. During the winding process, it is necessary to ensure that the steel tape is tightly attached without loosening, wrinkling and other phenomena. The lap width of the armouring also has strict requirements to ensure the overall strength of the armouring layer.
The sheath extrusion process is similar to the insulation layer extrusion, but the materials and process parameters used are different. The sheath material (such as PVC) is added to the extruder, melted and wrapped around the armouring layer to form the outer sheath. During extrusion, it is necessary to ensure that the sheath is closely combined with the armouring layer, with uniform thickness and no defects on the surface.
The finished product inspection link covers a number of index tests. Including conductor resistance test to check whether the conductivity of the aluminium conductor meets the standard; insulation resistance and voltage withstand test to verify the insulation performance of the XLPE insulation layer; mechanical performance test, such as tensile test and bending test, to test the tensile and bending resistance of the cable; and adhesion test of the armouring layer to ensure that the armouring layer will not fall off easily. Only cables that meet all the test standards can leave the factory as finished products.
II. General Product Information
(I) Packaging
In order to ensure that the Arvfv aluminium core power cable is not damaged during storage and transportation, the packaging link has been scientifically designed.
For coiled cables, wooden or metal reels are usually used for packaging. The size of the reel is determined according to the length and diameter of the cable to ensure that it can stably carry the weight of the cable. The cable is neatly wound on the reel, and appropriate tension is maintained during winding to prevent the cable from loosening or rubbing against each other. Baffles are installed on both sides of the reel to prevent the cable from sliding off both sides of the reel. The outside of the reel will be wrapped with a strong plastic film to prevent moisture and dust.
For small - length cables, such as samples or small - batch orders, sealed plastic woven bags are used for packaging. The woven bag has certain strength and wear resistance, which can protect the cable from slight collisions and friction. Desiccants will be placed in the bag to prevent the cable from getting damp during storage.
Clear labels will be pasted on the package, indicating the product name, specification (4×70mm² or 4c×95mm²), length, rated voltage, production batch number, production date, manufacturer information and other contents. At the same time, some warning signs, such as "Do not press heavily", "Keep away from moisture and sunlight", "Up" and so on, will be marked on the labels to remind relevant personnel to pay attention to relevant matters during handling and storage.
(II) Transportation
The transportation of Arvfv aluminium core Power Cables must follow strict specifications to ensure the safety of the cables during transportation. The transportation method can be selected according to the order quantity and transportation distance. For large quantities of cables, road transportation or railway transportation is usually adopted. For road transportation, the reels are loaded on special transport vehicles, and the reels are fixed firmly with steel wire ropes or fastening belts to prevent the reels from rolling or colliding during transportation. During the driving process of the vehicle, sudden braking and sharp turns should be avoided to reduce the vibration and impact of the cable. Railway transportation can use the stable advantage of railway freight cars to place and fix the reels reasonably to ensure transportation safety. Small batches or sample cables can be transported by express or less - than - carload logistics, and the same fixing and protection should be done during transportation.
During transportation, attention should be paid to avoiding the cable from being affected by extreme temperatures. High temperatures may cause the sheath to soften, and low temperatures may make the sheath brittle. At the same time, it is necessary to prevent the cable from being wetted or soaked by rain to avoid moisture entering the cable and affecting its performance. The transport vehicle should be kept clean to prevent the cable from being contaminated by oil, chemicals, etc. Transport personnel must be familiar with the characteristics of the cable, and handle it with care during loading and unloading to avoid damaging the reel or the cable sheath due to brute force.
