I. Product-specific Information
(1) Specifications and Parameters
Single core 95mm², 120mm², 150mm², 185mm², 240mm² U-1000, Ar2V, Yjlv, Na2xy
Aluminum Core Power Cables have rigorous and detailed settings in terms of specifications and parameters to meet the diversified needs of medium and
Low Voltage Power transmission.
In terms of conductor specifications, all these cables use high-purity aluminum as the conductor, with a purity of more than 99.5%. Conductors with different cross-sectional areas have differences in structure. The 95mm² conductor is composed of multiple
Aluminum Wires with a diameter of about 0.3mm stranded together, with a total cross-sectional area of 95mm²; the 120mm² conductor has slightly thicker
Aluminum Wires and a corresponding increase in the number of strands; the 150mm², 185mm², and 240mm² specifications follow this pattern. As the cross-sectional area increases, the diameter or number of aluminum wires is gradually adjusted to ensure the conductivity and mechanical strength of the conductor.
Current-carrying capacity is an important parameter of such cables. At an ambient temperature of 25℃, the current-carrying capacity of 95mm² cable is about 180-220A, 120mm² is about 210-250A, 150mm² is about 240-280A, 185mm² is about 280-320A, and 240mm² is about 340-380A. This parameter range can flexibly match electrical equipment of different powers, from small and medium-sized motors in industry to power distribution systems of large production lines, and suitable specifications can be found.
In terms of electrical performance, the rated voltage of these cables is compatible with the U-1000 standard, meeting the requirements of medium and low voltage power transmission. The insulation layer is made of cross-linked polyethylene (XLPE), with an insulation resistance of not less than 1000MΩ·km at 20℃ and a dielectric loss tangent value of not more than 0.003, which has excellent electrical insulation performance, can effectively prevent current leakage, and reduce power loss. At the same time, the partial discharge of the cable is controlled at a low level. Under normal working voltage, the partial discharge does not exceed 10pC, ensuring the stability of power transmission.
In terms of mechanical performance, there are slight differences between different models of cables. Yjlv cable has a tensile strength of not less than 12MPa, an elongation at break of not less than 150%, a static bending radius of not less than 12 times the outer diameter of the cable, and a dynamic bending radius of not less than 20 times the outer diameter of the cable, which can withstand a certain degree of external tension and bending. Na2xy has better mechanical performance due to the addition of
Steel Tape armoring, with a tensile strength of not less than 18MPa, an elongation at break of not less than 120%, a static bending radius of not less than 15 times the outer diameter of the cable, and a dynamic bending radius of not less than 25 times the outer diameter of the cable, with stronger resistance to mechanical damage. A
R2V Cable is designed for complex environments, with a tensile strength of not less than 14MPa, an elongation at break of not less than 140%, and its bending performance can also meet the laying needs of complex scenarios.
(2) Characteristic Applications
U-1000, Ar2V, Yjlv, and Na2xy aluminum core power cables have unique applications in different scenarios due to their respective performance characteristics.
Yjlv, as a cross-linked polyethylene insulated and polyvinyl chloride sheathed
Aluminum Core Cable, is suitable for general industrial and building power distribution scenarios. In the power distribution system of ordinary residential communities, 120mm² and 150mm² Yjlv cables are often used for the trunk lines from the community distribution room to each building, providing stable guarantee for residents' daily electricity use. In small and medium-sized industrial plants, such as textile mills and food processing plants, this type of cable can be used to connect the power distribution lines of various production equipment. The 95mm² specification is suitable for small equipment, and the 185mm² and 240mm² specifications are used for power supply of large equipment.
Na2xy Cable has stronger resistance to mechanical damage due to the addition of steel tape armoring, making it very suitable for direct burial laying. In the
Underground Cable projects of urban power grids, it is necessary to transmit power from substations to various regions. Using 240mm² Na2xy cables for direct burial underground can effectively resist external mechanical impacts such as ground vehicle rolling and construction excavation, ensuring the continuity of power transmission. The internal power distribution lines in industrial parks also widely use 185mm² Na2xy cables for direct burial laying because there may be rolling by forklifts, trucks, and other heavy vehicles.
Ar2V cable has specific protective performance and is suitable for complex environments. In chemical industrial parks, the air may contain corrosive gases, and the ground may have acid and alkali liquids. 150mm² and 185mm² Ar2V cables can resist these corrosive factors and provide reliable power support for chemical equipment. In humid underground parking lots, sewage treatment plants, and other places, this type of cable can also maintain stable performance, ensuring the normal operation of the power distribution system.
The U-1000 model cable plays a role in some specific power transmission scenarios, such as urban road lighting lines. Using 95mm² and 120mm²
U-1000 Cables can meet the power demand of street lamps, and their performance is stable, which can be used in outdoor environments for a long time.
In addition, these cables are also widely used in high-rise buildings. In the shaft wiring of high-rise buildings, according to the different floor heights and electrical loads, 120mm² and 150mm² cables can be selected. Yjlv and Ar2V cables are flexible and easy to lay in the limited space in the shaft; for parts that need to pass through floor slabs and may be subject to mechanical impact, Na2xy cables can be selected.
(3) Material and Style
Material
Conductor: High-purity aluminum material is used with a purity of more than 99.5%. Aluminum has good electrical conductivity. Although its conductivity is slightly lower than that of copper, it has a small density and light weight, which can reduce the overall weight of the cable, facilitating transportation and laying. At the same time, the price of aluminum is relatively low, which can reduce the cost of power engineering. Through special processing technology, the surface of the Aluminum Conductor is smooth, which reduces the skin effect during current transmission and improves the conductivity efficiency.
Insulation layer: All use cross-linked polyethylene (XLPE), which is a polyethylene material after cross-linking treatment. The cross-linked XLPE forms a three-dimensional network structure, with excellent heat resistance. The long-term working temperature can reach 90℃, and the short-term overload temperature can reach 130℃, which can adapt to temperature changes during power transmission. In addition, XLPE also has good chemical stability, resistance to acid, alkali, oil, and other corrosion, excellent insulation performance, and a long service life.
Sheath: Polyvinyl chloride (PVC) material is used. The PVC Sheath has good mechanical strength, which can protect the internal insulation layer and conductor from external mechanical damage, such as extrusion and collision. At the same time, PVC has certain weather resistance, which can resist the erosion of natural factors such as sunlight, rain, and oxygen, and prolong the service life of the cable. For Na2xy cables, there is also a steel tape armor layer inside the PVC sheath. The steel tape is made of high-quality low-carbon steel with a thickness of about 0.3-0.5mm, which further enhances the cable's resistance to mechanical damage.
Style
These cables are all single-core structures with a circular appearance. Cables of different specifications have different outer diameters. The outer diameter of 95mm² is about 20mm, 120mm² is about 22mm, 150mm² is about 25mm, 185mm² is about 28mm, and 240mm² is about 32mm.
In terms of color, the sheaths of Yjlv and
U-1000 Cables are mostly black. Black has good ultraviolet resistance and is suitable for outdoor use; the sheath color of Ar2V cables may be gray or other specific colors according to their protective performance, to distinguish them from ordinary cables; Na2xy cables have a relatively thick sheath appearance due to the steel tape armor, and the color is mostly black.
The sheath surface of the cable is usually printed with clear marks, including model, specification, rated voltage, manufacturer, production date, etc., which is convenient for users to identify and select. For example, "Yjlv - 1000V - 120mm²" can be seen on the cable sheath, which intuitively reflects the key parameters of the cable.
(4) Production Process
The production process of single core 95mm², 120mm², 150mm², 185mm², 240mm² U-1000, Ar2V, Yjlv, Na2xy aluminum core power cables is advanced and complex, ensuring the excellent performance of the products.
In the conductor manufacturing process, first, high-purity 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 mold precision are strictly controlled to ensure the uniform diameter of the aluminum wires. Then, the aluminum wires are annealed. The aluminum wires are heated to a certain temperature (about 300-400℃) and kept for a period of time to eliminate internal stress in the aluminum wires and enhance their
Flexibility and conductivity. The annealed aluminum wires are stranded according to the requirements of different cross-sectional areas. Advanced stranding equipment is used in the stranding process, and the stranding pitch and tension are well controlled to ensure the roundness and structural stability of the conductor.
Insulation layer extrusion is one of the key processes, using cross-linked polyethylene (XLPE) as the
Insulation Material. XLPE particles are added to the extruder, melted and plasticized at high temperature (about 120-180℃), and then uniformly extruded and coated on the surface of the conductor through a mold to form an insulation layer. During the extrusion process, the extrusion temperature, speed, and pressure are strictly controlled to ensure uniform sheath thickness, smooth surface, and close combination with the conductor. After extrusion, the insulation layer is cross-linked, usually using a dry cross-linking process. The cable with the extruded insulation layer is passed through a cross-linking tube, and cross-linking reaction is carried out in a high-temperature and high-pressure nitrogen environment, so that XLPE molecules form a three-dimensional network structure, thereby improving the heat resistance and mechanical properties of the insulation layer.
In the sheath extrusion process, for Yjlv, U-1000, and Ar2V cables, polyvinyl chloride (PVC) particles are added to the extruder, heated to a molten state (about 150-170℃), and extruded and coated on the outside of the insulation layer through a mold to form a sheath. For Na2xy cables, before sheath extrusion, a steel tape armoring process is also required. High-quality low-carbon steel tape is wrapped around the outside of the insulation layer at a certain angle through an armoring machine. During the armoring process, the wrapping tension and overlap rate (not less than 15%) are controlled to ensure the tightness and continuity of the armor layer, and then the PVC sheath is extruded.
During the production process, each process is equipped with strict quality inspection. In the conductor process, the diameter and tensile strength of aluminum wires are inspected; in the insulation layer process, insulation thickness, insulation resistance, dielectric loss, etc., are inspected; in the sheath process, sheath thickness, tensile strength, elongation at break, etc., are inspected. In addition, finished cables also need to undergo partial discharge tests, withstand voltage tests, etc., to ensure that the products meet relevant standards and technical requirements.
II. General Product Information
(1) Packaging
To ensure the quality of single core 95mm², 120mm², 150mm², 185mm², 240mm² U-1000, Ar2V, Yjlv, Na2xy aluminum core power cables during transportation and storage, the packaging method is carefully designed.
For long-length cables, steel cable reels are usually used for packaging. The diameter of the cable reel depends on the cable specification. Cables of 95mm² and 120mm² can use cable reels with a diameter of 1200mm, 150mm² and 185mm² use cable reels with a diameter of 1400mm, and 240mm² use cable reels with a diameter of 1600mm. Both sides of the cable reel are equipped with solid baffles with a thickness of not less than 25mm, which can effectively prevent the cable from slipping during transportation. The center of the cable reel is provided with a shaft hole, which is convenient for handling and loading/unloading with hoisting equipment.
When the cable is wound on the cable reel, it is arranged in a tight manner to avoid damage caused by friction between cables. After winding, the outer layer of the cable is wrapped with a layer of plastic film to play the role of moisture-proof, dust-proof, and oil-proof. For each reel of cable, key product information is clearly marked on the side of the cable reel, including model, specification, length, weight, rated voltage, manufacturer, production date, implementation standard, etc., which is convenient for customers to identify when receiving and counting. The packaging is also printed with warning signs such as "Do not invert", "Handle with care", "Moisture-proof and sun-proof" to remind transportation and storage personnel to pay attention to protecting the cable.
For short-length cables, such as samples or small orders, they are packaged in rolls. The cable is neatly wound into a roll, tightly wrapped with plastic film, and then put into a high-strength carton. The inside of the carton is padded with buffer materials to prevent the cable from being damaged by extrusion during transportation. The relevant information and warning signs of the product are also marked on the outside of the carton.
(2) Transportation
Transportation methods: According to the different transportation distance and order quantity, select the appropriate transportation method. For short-distance transportation (distance within 300 kilometers), road transportation is generally used, and trucks are used to load cable reels. The trucks need to be equipped with special fixing devices, such as steel wire ropes and tighteners, to firmly fix the cable reels in the carriage to prevent shaking during transportation. For long-distance transportation (distance over 300 kilometers), railway transportation or waterway transportation can be selected. Railway transportation has the characteristics of good stability and large carrying capacity, which is suitable for transporting large quantities of cables; waterway transportation has relatively low cost and is suitable for areas with ports.
Transportation precautions: During transportation, the cable reel must be placed horizontally, and it is strictly forbidden to tilt or invert to avoid the cable slipping from the cable reel and causing damage. A certain distance should be kept between cable reels, usually not less than 50cm, to prevent mutual collision and extrusion, which may cause damage to the cable sheath and internal structure. Transport vehicles or means of transport should take rain-proof, sun-proof, and dust-proof measures, such as covering with rain-proof cloth and sunshades, to avoid the cable being damp, exposed to direct sunlight, or polluted by dust.
When loading and unloading the cable reel, special hoisting equipment, such as cranes and forklifts, must be used. The hoisting point should be selected at the lifting ring of the cable reel. Hoisting at the baffle or other parts is strictly prohibited to avoid damaging the cable reel and the cable. During the hoisting process, the cable reel should be kept stable to avoid violent shaking. During transportation, drivers should abide by traffic rules, drive smoothly, and avoid sudden braking, sharp turns, and other operations to reduce the impact on the cable.
