Detailed Introduction to 660/1000 V Avbbshv Ng-Ls and Vbbshv Ng-Ls Power Cables
I. From the Perspective of the Product Itself
(I) Specification Parameters
The 660/1000 V Avbbshv Ng-Ls and Vbbshv Ng-Ls
Power Cables have detailed and clear regulations in terms of specification parameters to ensure their stable and reliable operation in low-voltage distribution systems.
In terms of rated voltage, both cables are 660V/1000V. This voltage level enables them to meet the needs of most low-voltage distribution scenarios, applicable to both 380V industrial power systems and 220V civil power supply systems, thus having wide applicability.
The conductor cross-sectional specifications are rich and diverse, covering multiple grades from 1.5mm² to 240mm². Small cross-sectional cables such as 1.5mm² and 2.5mm² are often used in power supply lines for household lighting and small electrical appliances; 4mm² and 6mm² cables can be used for power supply of high-power household appliances such as air conditioners and electric water heaters, as well as small motors; cross-sections of 10mm² and above are mainly used in industrial equipment, building distribution trunks, etc. Taking a 16mm² cable as an example, the current-carrying capacity of Vbbshv Ng-Ls (
Copper Conductor) when laid in air is about 70A, and that of Avbbshv Ng-Ls (
Aluminum Conductor) is about 58A. As the cross-section increases, the current-carrying capacity also increases accordingly. The current-carrying capacity of 240mm² Vbbshv Ng-Ls can reach more than 400A, while that of Avbbshv Ng-Ls is more than 300A.
DC resistance is an important indicator to measure the conductivity of conductors. Vbbshv Ng-Ls uses high-purity
Copper Conductors (purity ≥99.9%), and its DC resistance is controlled at an extremely low level. For example, the DC resistance of 10mm² cross-sectional conductors is ≤1.83Ω/km, 16mm² cross-sectional conductors is ≤1.15Ω/km, and 25mm² cross-sectional conductors is ≤0.727Ω/km. Avbbshv Ng-Ls uses high-purity
Aluminum Conductors (purity ≥99.5%), with relatively higher DC resistance. The DC resistance of 10mm² cross-sectional conductors is ≤3.08Ω/km, 16mm² cross-sectional conductors is ≤1.91Ω/km, and 25mm² cross-sectional conductors is ≤1.20Ω/km, but it can still meet the requirements of low-voltage distribution.
In terms of insulation performance, the insulation resistance of the insulation layer of both cables is ≥10¹⁴Ω·m, which can effectively prevent current leakage and ensure the safety of power transmission. The temperature resistance performance is outstanding, with a long-term working temperature of up to 90℃, much higher than 70℃ of conventional
PVC Cables, and it can operate stably in industrial plants and other places with high ambient temperatures; the temperature resistance can reach 250℃ in case of short circuit (within 5 seconds), providing a certain safety buffer time in case of circuit failure and reducing the risk of cable damage caused by short-circuit high temperature.
In terms of mechanical properties, the outer sheath of both cables has a tensile strength of ≥12MPa and an elongation at break of ≥150%, which has good tensile and deformation resistance and can resist external mechanical damage such as extrusion and friction. The bending performance is excellent, with a minimum bending radius of 6-10 times the outer diameter of the cable. Among them, the minimum bending radius of non-armored models is 6 times the outer diameter (static) and 8 times the outer diameter (dynamic), which is convenient for wiring construction in narrow spaces and complex environments.
The shielding layer is an important part of both cables. It is made of semi-conductive materials with a uniform thickness, usually between 0.5mm-1mm, which can effectively uniform the electric field distribution, reduce the risk of partial discharge, and improve the stability of cable operation. The volume resistivity of the shielding layer is ≤100Ω·cm, ensuring its good shielding effect.
(II) Characteristic Uses
The 660/1000 V Avbbshv Ng-Ls and Vbbshv Ng-Ls power cables have distinct characteristic uses in different fields due to their unique properties.
Vbbshv Ng-Ls uses high-purity copper conductors, with excellent conductivity and large current-carrying capacity, suitable for occasions with high requirements for conduction efficiency and stability. In the industrial field, it is often used for power supply of precision equipment and automated production lines in industrial plants. These equipment have extremely high requirements for power quality, and the slightest voltage fluctuation or current instability may cause equipment failure, while Vbbshv Ng-Ls can provide stable and reliable power support for them. In high-rise buildings, as a distribution trunk, it can efficiently transmit power from the bottom distribution room to each floor, meeting the needs of a large number of electrical equipment in high-rise residences, commercial buildings, etc. In addition, in data centers, servers, switches and other equipment need to operate 24 hours a day, with strict requirements for the continuity and stability of power, so Vbbshv Ng-Ls is also an ideal choice.
Avbbshv Ng-Ls uses aluminum conductors, which are light in weight, low in cost, and have good corrosion resistance, suitable for long-distance laying or cost-sensitive projects. In the transformation of rural power grids, due to the vast area of rural areas and long transmission lines, the lightweight characteristics of Avbbshv Ng-Ls reduce the difficulty and cost of erection, and its corrosion resistance can adapt to the complex natural environment in rural areas. In outdoor photovoltaic
Power Stations, as a connecting line, it transmits the power generated by solar panels to the inverter. Photovoltaic power stations usually cover a large area and have long lines, so Avbbshv Ng-Ls can ensure transmission efficiency while reducing construction costs. In temporary construction power supply scenarios, such as construction sites, a large number of cables need to be laid temporarily, and the low cost and easy handling characteristics of Avbbshv Ng-Ls make it widely used.
Both cables have passed the low-smoke halogen-free certification, with low smoke concentration and low toxicity when burned. This characteristic makes them have unique advantages in densely populated places and enclosed spaces. In densely populated places such as shopping malls and hospitals, in case of fire, low-smoke
Halogen-Free Cables can reduce the obstruction of smoke to personnel evacuation and the harm of toxic gases to the human body; in enclosed spaces such as subways and tunnels, smoke and toxic gases are not easy to spread, and low-smoke halogen-free cables can buy more time for rescue work and reduce accident losses.
(III) Material and Style
Material
The conductor of Vbbshv Ng-Ls uses high-purity copper (purity ≥99.9%). Copper has excellent conductivity and high conductivity, which can effectively reduce losses during current transmission and ensure efficient transmission of electricity. Copper has good ductility and toughness, which is easy to be processed into multi-strand
Stranded Conductor structure, enhancing the
Flexibility of the cable and making it easy to bend and install. At the same time, copper has high chemical stability, is not easy to be corroded in normal use environment, and can maintain good conductivity for a long time.
The conductor of Avbbshv Ng-Ls uses high-purity aluminum (purity ≥99.5%). Although the conductivity of aluminum is not as good as that of copper, it is light in weight, with a density of only about 1/3 of that of copper, which greatly reduces the self-weight of the cable and is convenient for long-distance laying and handling. The cost of aluminum is relatively low, which can effectively control the overall cost of the cable. In addition, aluminum will form a dense oxide film in the air, which can prevent further oxidation of aluminum, endowing it with good corrosion resistance, suitable for use in outdoor environments.
The insulation layers of both cables are made of materials with high temperature resistance, usually cross-linked polyethylene (XLPE) or ethylene propylene rubber (EPR). XLPE has excellent insulation performance, temperature resistance and mechanical strength. After cross-linking treatment, its molecular structure forms a three-dimensional network structure, making its long-term working temperature reach 90℃, and the temperature resistance reaches 250℃ in case of short circuit. Moreover, it has high insulation resistance, which can effectively isolate the conductor from the outside world. EPR has good weather resistance, ozone resistance and chemical corrosion resistance, and can also meet the insulation requirements of cables.
The outer sheath is made of flame-retardant low-smoke halogen-free materials, such as polyolefin. This material has good flame retardant performance, complying with the GB/T 18380 flame retardant standard, and can delay the spread of flames in case of fire. At the same time, the smoke concentration generated during its combustion is low and the toxicity is small, meeting the requirements of "Ng-Ls" low-smoke halogen-free. In addition, the sheath material also has acid-alkali resistance and oil resistance, and can adapt to harsh environments such as dust and humidity, protecting the internal structure from damage.
The shielding layer is made of semi-conductive materials, usually semi-conductive polyolefin or semi-conductive rubber. The volume resistivity of semi-conductive materials is low, which can make good contact with conductors and insulation layers, playing the role of uniform electric field and reducing the risk of insulation aging and breakdown caused by excessive local electric field strength.
Style
In terms of appearance, both cables are cylindrical with smooth and flat surfaces. Due to the use of low-smoke halogen-free sheath materials, the color is usually black or gray. Black has good weather resistance, can absorb sunlight and heat, and reduce the impact of temperature changes on the cable; gray is easier to coordinate with the surrounding environment in some indoor environments.
The conductor structure is a multi-strand stranded design. Multiple strands of fine
Copper Wires or
Aluminum Wires are stranded together according to a certain lay direction and pitch to form a
Flexible Conductor with good conductivity. This stranded structure makes the cable have good bending performance, which is convenient for installation and laying in narrow spaces and complex environments. The lay pitch varies according to the size of the cable cross-section, generally 10-20 times the outer diameter of the conductor, to ensure the structural stability and flexibility of the conductor.
The insulation layer is tightly wrapped around the outside of the conductor, closely fitting with the conductor, without bubbles and gaps, ensuring the insulation effect. The thickness of the insulation layer depends on the rated voltage and cross-sectional specification of the cable, usually between 0.8mm-2mm. The higher the voltage level and the larger the cross-section, the thicker the insulation layer.
The shielding layer is evenly wrapped around the outside of the insulation layer, closely combined with the insulation layer, ensuring uniform electric field distribution. The thickness of the shielding layer is generally 0.5mm-1mm, which can effectively play a shielding role.
The sheath is evenly wrapped around the outside of the shielding layer, forming a solid protective layer. The thickness of the sheath is usually between 1.0mm-2.0mm, with good mechanical strength and protective performance. The surface of the sheath is printed with the model, specification, rated voltage, manufacturer and other marks of the cable, which are clear and easy to identify, facilitating users' selection and traceability.
(IV) Production Process
The production process of 660/1000 V Avbbshv Ng-Ls and Vbbshv Ng-Ls power cables is complex and rigorous, and each link is strictly controlled to ensure the quality and performance of the products.
Conductor manufacturing is the first step of production. For the copper conductor of Vbbshv Ng-Ls, high-purity copper ingots are smelted and cast into copper rods. The quality of copper rods directly affects the performance of subsequent conductors. Therefore, parameters such as temperature and impurity content need to be strictly controlled during smelting and casting to ensure the purity and uniformity of copper rods. Then, the copper rod is drawn into a copper wire of the required diameter through a wire drawing machine. During the wire drawing process, the drawing speed and the precision of the die must be controlled to ensure that the diameter of the copper wire is uniform, the surface is smooth, and there are no scratches or burrs. Next, multiple strands of copper wire are stranded according to a certain stranding scheme. During stranding, the tension of each strand of copper wire must be uniform, and the stranding direction and pitch must meet the design requirements to ensure the structural stability and flexibility of the conductor.
The manufacturing process of the aluminum conductor of Avbbshv Ng-Ls is similar to that of the copper conductor, but due to the low hardness of aluminum, more attention should be paid to controlling the force during wire drawing and stranding to avoid
Aluminum Wire breakage. High-purity aluminum ingots are smelted and cast into aluminum rods, then drawn into aluminum wires, and then stranded. Similarly, the diameter uniformity and stranding quality of aluminum wires must be ensured.
The extrusion of the insulation layer is one of the key processes. The stranded conductor is fed into the extruder, and at the same time, the
Insulation Material (such as XLPE or EPR) is heated and melted, then evenly wrapped around the outside of the conductor through the extrusion die to form the insulation layer. During the extrusion process, the extrusion temperature, extrusion speed and die pressure must be strictly controlled to ensure that the thickness of the insulation layer is uniform, closely combined with the conductor, and free of bubbles, impurities and other defects. For
XLPE Insulation Materials, after extrusion, cross-linking treatment is required, usually by means of warm water cross-linking or steam cross-linking. The insulation layer is heated to a certain temperature and kept for a period of time to make the polyethylene molecules undergo a cross-linking reaction to form a three-dimensional network structure, so as to improve the temperature resistance and mechanical strength of the insulation layer.
The coating process of the shielding layer follows the insulation layer. The semi-conductive material is heated and melted, then evenly coated on the outside of the insulation layer through the extrusion die to form the shielding layer. The thickness of the shielding layer should be uniform and closely combined with the insulation layer to ensure that it can effectively uniform the electric field.
The extrusion of the sheath is the last main process. The wire core after shielding treatment is fed into the sheath extruder. The low-smoke halogen-free flame-retardant sheath material is heated and melted in the extruder, then wrapped around the outside of the shielding layer through the extrusion die to form the sheath. During the extrusion process, the extrusion parameters must be controlled to ensure that the thickness of the sheath is uniform, the surface is smooth, closely combined with the shielding layer, and free of bubbles, material shortage and other defects. The extruded cable is cooled, pulled, and taken up to form the finished cable.
During the production process, multiple quality inspection procedures are also required. After the conductor is manufactured, its diameter, DC resistance and other parameters must be tested; after the insulation layer is extruded and cross-linked, the thickness, insulation resistance, temperature resistance, mechanical properties and other properties of the insulation layer must be tested; after the shielding layer is coated, its thickness and volume resistivity must be tested; after the sheath is extruded, the thickness, tensile strength, elongation at break, flame retardant performance, low-smoke halogen-free performance and other properties of the sheath must be tested. In addition, the finished cable needs to undergo overall withstand voltage tests, partial discharge tests, bending tests, etc., to ensure that all performance indicators of the cable meet relevant standards and design requirements.
Environmental control during production is also very important. The workshop needs to be kept clean and dry, and the temperature and humidity are controlled within appropriate ranges to avoid the impact of dust, moisture, etc. on product quality. At the same time, production equipment needs regular maintenance to ensure its normal operation, improve production efficiency and product quality stability.
II. From the Perspective of General Product Information
(I) Packaging
In order to ensure the quality of 660/1000 V Avbbshv Ng-Ls and Vbbshv Ng-Ls power cables during transportation and storage, their packaging methods are carefully designed, and different packaging forms are adopted according to the length and weight of the cables.
For short-length cables (usually within 100 meters), plastic reels are used for packaging. The plastic reels are made of high-strength polyethylene material, which has certain pressure resistance and wear resistance, and can protect the cables from damage during transportation and handling. The cable is neatly wound on the reel, and appropriate tension is maintained during winding to avoid loose cables and mutual friction. After winding, the entire reel and cable are tightly wrapped with plastic film, which has good moisture-proof and dust-proof performance and can effectively prevent the cable from being polluted and eroded by the external environment. Both ends of the reel are equipped with circular baffles, the diameter of which is larger than that of the reel, which can effectively prevent the cable from slipping off the reel. The baffles are printed with the model, specification, length and other information of the cable, which is convenient for users to identify.
For long-length cables (usually more than 100 meters), wooden cable reels are used for packaging. The wooden cable reels are made of high-quality hardwood, which has been dried and has a solid structure, able to bear a large weight. The cable is tightly wound on the cable reel, and the number of winding layers and tension are strictly controlled to ensure that the cable will not loosen or deform during transportation. The outermost layer of the cable is also wrapped with a layer of plastic film to play a role in moisture-proof and dust-proof. Both sides of the wooden cable reel are equipped with metal flanges, and the flanges are provided with multiple holes, which are convenient for handling and loading/unloading with forklifts and other equipment. At the same time, a label is nailed on the wooden cable reel, which clearly indicates the model, specification, length, weight, manufacturer, production date, execution standard and other information
of the cable, facilitating users' verification and traceability.
Whether it is plastic reel or wooden cable reel packaging, obvious warning signs such as "Do not press heavily", "Moisture-proof", "Up", "Handle with care" are printed on the outside of the packaging to remind transportation and storage personnel to pay attention to relevant matters and avoid damage to the cable due to improper operation. For low-smoke halogen-free cables, marks such as "Low-smoke halogen-free" and "Flame-retardant" are also printed on the packaging to highlight the characteristics of the product.
(II) Transportation
The transportation of 660/1000 V Avbbshv Ng-Ls and Vbbshv Ng-Ls power cables needs to select appropriate transportation methods according to factors such as transportation distance, quantity, destination, etc., and take corresponding protective measures to ensure the safety of the cables during transportation.
Road transportation is one of the most commonly used transportation methods, suitable for short-distance and medium-distance transportation. The transport vehicles are closed trucks or semi-trailers to prevent the cables from being exposed to direct sunlight, rain, dust pollution and bad weather. During loading, the packaged cable reels are neatly stacked in the carriage, and wooden boards or other buffer materials are placed between the cable reels to prevent mutual collision and damage. For wooden cable reels, steel wire ropes or fastening belts are used to firmly fix them in the carriage to ensure that they will not shake or shift during transportation. During transportation, drivers should pay attention to controlling the speed, avoid sudden braking and sharp turns, reduce the impact force on the cables, and at the same time abide by traffic rules to ensure transportation safety.
Railway transportation is suitable for long-distance and large-volume cable transportation, with the advantages of large transportation volume, low cost and good stability. During railway transportation, the cable reels are placed in the designated positions of the railway freight cars and fixed firmly with special fixing devices to prevent displacement and collision during transportation. At the same time, moisture-proof and dust-proof measures should be taken, such as covering the cable reels with waterproof cloth to avoid moisture and pollution of the cables. The railway department will monitor the transportation process throughout to ensure the safe transportation of goods.
Waterway transportation is mainly used for international trade or long-distance coastal transportation. Cables are transported by cargo ships, and the cable reels are reasonably placed in the cabin to avoid stacking too high and prevent the underlying cable reels from being crushed and damaged. During transportation, attention should be paid to ventilation and moisture-proof in the cabin to avoid damage to the cables due to moisture. At the same time, fixing measures should be taken to prevent the cable reels from moving due to 颠簸 during the ship's navigation.
No matter which transportation method is adopted, it is necessary to avoid severe collision, extrusion, bending and exposure of the cables to the sun. Transport personnel should be familiar with the characteristics and transportation requirements of the cables, handle them with care during loading and unloading, avoid using sharp tools, and prevent damage to the packaging and sheath of the cables. During transportation, attention should be paid to the weather conditions at any time, and corresponding protective measures should be taken when encountering bad weather to ensure that the cables are delivered to the destination safely and on time.
