I. Product-specific Information
(1) Specifications and Parameters
The 0.6/1 Kv specification Nayy, Na2xy, Na2xoh, Hn3353, Bt
Aluminum Core Power Cables have clear and detailed settings in terms of specifications and parameters to meet the power transmission needs of different scenarios.
In terms of conductor specifications, all such cables use aluminum as the conductor, covering specifications such as 3-1X120 mm² and 3-1X240 mm². "3-1X" indicates that the cable is a single-core multi-strand combined structure, and 120 mm² and 240 mm² are the cross-sectional areas of the conductor. The current-carrying capacity of conductors with different cross-sectional areas varies significantly. At an ambient temperature of 25℃, the current-carrying capacity of the 3-1X120 mm² specification is about 200-250A, and that of the 3-1X240 mm² specification is about 300-350A, which can be accurately matched according to the power load.
In terms of electrical performance parameters, the rated voltage of these cables is 0.6/1 Kv, which meets the standards for medium and
Low Voltage Power transmission.
Nayy Cable uses polyvinyl chloride (PVC) insulation, with an insulation resistance of not less than 500MΩ·km at 20℃; Na2xy and Hn3353 use cross-linked polyethylene (XLPE) insulation, with an insulation resistance of not less than 1000MΩ·km at 20℃ and a dielectric loss tangent value of not more than 0.003, having better electrical insulation performance; Na2xoh has oil-resistant characteristics, and its
Insulation Material has been specially treated, with an insulation resistance of not less than 800MΩ·km at 20℃; Bt, as a thin-walled
Sheathed Cable, has an insulation resistance of not less than 600MΩ·km at 20℃, which can meet the insulation requirements of general power transmission. In addition, the partial discharge of these cables is controlled at a low level to ensure the stability of power transmission.
In terms of mechanical performance parameters, due to the adoption of a
Steel Tape armored structure, Na2xy has 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, having strong resistance to mechanical damage. Nayy, Na2xoh, and Hn3353 have 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. Bt, as a thin-walled sheathed cable, has a tensile strength of not less than 10MPa, an elongation at break of not less than 160%, and a minimum bending radius of not less than 10 times the outer diameter of the cable, which is more suitable for laying scenarios with limited space.
(2) Characteristic Applications
Nayy, Na2xy, Na2xoh, Hn3353, and Bt aluminum core power cables have characteristic applications in different scenarios due to their respective performance characteristics.
Nayy cable, as a polyvinyl chloride insulated and sheathed cable, is relatively low in price and has certain insulation and protection performance, suitable for building power distribution in general environments. In the power distribution system of residential communities, the 3-1X120 mm² specification Nayy cable is often used for the trunk lines from the distribution room to each building and the branch lines in the building, providing stable support for residents' daily electricity use. In small commercial places, such as supermarkets, convenience stores, etc., the internal power distribution lines also widely use this type of cable.
Na2xy is a cross-linked polyethylene insulated steel tape armored
Polyvinyl Chloride Sheathed Cable. Its armored structure gives it excellent resistance to mechanical damage, suitable for direct burial laying. In industrial plant power transmission, it is necessary to transmit power from the main substation to each workshop. Since there may be vehicle rolling, equipment handling, etc. on the plant ground, the 3-1X240 mm² specification
Na2xy Cable is used for direct burial laying, which can effectively resist external mechanical impact and ensure the continuity of power transmission. This type of cable is also often used for
Underground Cable laying in municipal engineering, such as road lighting lines, underground parking lot power supply lines, etc.
Na2xoh cable has oil-resistant characteristics, suitable for industrial scenarios with oily environments. In mechanical processing plants, various machine tools will produce oil stains during operation, and their power distribution lines need to withstand oil erosion. The 3-1X120 mm² specification Na2xoh cable can meet this demand, providing reliable power for machine tools. This type of cable can also play a stable transmission role in the power distribution systems of automobile repair shops, gas stations and other places.
Hn3353 cable is suitable for high-temperature environments. In high-temperature workshops in metallurgy, chemical industry and other industries, the ambient temperature is relatively high, and ordinary cables are difficult to withstand, while Hn3353 cable can maintain stable performance at higher temperatures. For example, in the steelmaking workshop of a steel plant, the 3-1X240 mm² specification Hn3353 cable can be used to connect the power supply lines of high-temperature equipment to ensure the normal operation of the equipment.
Bt cable is a thin-walled sheathed cable, and its thin-walled design saves space, suitable for scenarios with limited space. In the shaft wiring of high-rise buildings, the space is narrow, and the 3-1X120 mm² specification Bt cable can easily pass through the limited space to complete the laying of power distribution lines. This type of cable is also widely used in the wiring inside large equipment, such as elevators, air conditioning units, etc., due to its space-saving feature.
(3) Material and Style
Material
Conductor: All use high-purity aluminum material 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, light weight, and relatively low price, which can reduce the overall cost of the cable, suitable for medium and low voltage power transmission. At the same time, aluminum has certain ductility and Flexibility, which is convenient for processing into conductors of different specifications and can adapt to certain bending and stretching during laying.
Insulation layer: Nayy uses polyvinyl chloride (PVC) insulation. PVC material has low cost, certain insulation performance and weather resistance, and can meet the use requirements of general environments. Na2xy and Hn3353 use cross-linked polyethylene (XLPE) insulation. After cross-linking treatment, XLPE forms a three-dimensional network structure, with good heat resistance. The long-term working temperature can reach 90℃, and the short-term overload temperature can reach 130℃, with excellent electrical insulation performance. The insulation layer of Na2xoh is added with oil-resistant additives on the basis of XLPE, making it have good oil-resistant performance and can resist oil erosion. The insulation layer of Bt cable is also PVC, but after special process treatment, the thickness is thinner on the premise of ensuring insulation performance.
Sheath: The sheaths of Nayy, Na2xy, Na2xoh, and Bt are all polyvinyl chloride (PVC). The PVC Sheath has good mechanical strength and corrosion resistance, which can protect the internal insulation layer and conductor from external damage. The sheath of Na2xy also contains a steel tape armor layer. 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. The sheath of Hn3353 is made of high-temperature resistant PVC material, which can maintain stable performance in high-temperature environments.
Style
The styles of these cables vary according to different models. Nayy, Na2xoh, and Bt cables have a circular appearance, with smooth and flat sheath surfaces, mostly black in color. Na2xy, due to the steel tape armor, has a relatively thick appearance. The armor layer is inside the sheath, and the armor lines can be vaguely seen from the outside. The sheath color of Hn3353 cable is usually gray to distinguish it from other models.
The outer diameter of the 3-1X120 mm² specification cable is relatively small, about 25-30mm; the outer diameter of the 3-1X240 mm² specification cable is larger, about 35-40mm. The sheath of the cable is usually printed with model, specification, rated voltage, manufacturer and other marks, which is convenient for identification and selection.
(4) Production Process
The production processes of Nayy, Na2xy, Na2xoh, Hn3353, and Bt aluminum core power cables have similarities and differences due to model characteristics.
First, in the manufacture of conductors, high-purity aluminum rods are drawn into
Aluminum Wires of the required diameter through a wire drawing machine, and then annealed to eliminate internal stress in the
Aluminum Wires and enhance their flexibility. After that, according to the requirements of different cross-sectional areas, multiple aluminum wires are stranded to form a conductor. During the stranding process, the stranding pitch is strictly controlled to ensure the roundness and stability of the conductor.
In the extrusion of the insulation layer, Nayy and Bt cables add PVC particles into the extruder, heat them to a molten state (temperature about 150-170℃), and uniformly extrude and coat them on the surface of the conductor through a mold to form an insulation layer. Na2xy, Na2xoh, and Hn3353 use XLPE insulation. XLPE particles are heated to a molten state (temperature about 120-180℃) and extruded and coated on the surface of the conductor. After extrusion, the insulation layers of Na2xy and Hn3353 are cross-linked, usually by dry cross-linking, so that XLPE molecules form a three-dimensional network structure; the insulation layer of Na2xoh is added with oil-resistant additives before extrusion, without additional cross-linking treatment.
For Na2xy cables, after the insulation layer is extruded, a steel tape armoring process is also required. High-quality low-carbon steel tape is wrapped around the outside of the insulation layer through an armoring machine, and the wrapping tension and overlap rate are controlled to ensure that the armor layer is closely attached to the insulation layer, enhancing the cable's resistance to mechanical damage.
In the cabling and sheath extrusion links, single-
Core Cables do not require a cabling process and directly perform sheath extrusion. The corresponding sheath material (PVC or high-temperature resistant PVC) is heated and melted, and then extruded and coated on the outside of the insulation layer or armor layer through an extruder to form a sheath. During the extrusion process, the temperature, speed, and pressure are controlled to ensure that the sheath has a uniform thickness, a smooth surface, and is closely combined with the internal structure. When extruding the sheath of Bt cable, the sheath thickness is controlled through a special mold to achieve a thin-walled design.
During the production process, each process undergoes strict quality inspection, including the detection of conductor diameter, insulation layer thickness, sheath thickness, electrical performance, mechanical performance and other indicators, to ensure that the products meet relevant standards.
II. General Product Information
(1) Packaging
To ensure the quality of 0.6/1 Kv Nayy, Na2xy, Na2xoh, Hn3353, Bt aluminum core power cables during transportation and storage, the packaging method is carefully designed.
For long-length cables, they are usually wound on steel cable reels. The diameter of the cable reel depends on the cable specification. Cables of 3-1X120 mm² specification can use cable reels with a diameter of 1200mm, while those of 3-1X240 mm² specification 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 to prevent the cable from slipping during transportation. The center of the cable reel is provided with a shaft hole for easy hoisting and handling.
After the cable is wound on the cable reel, the outer layer is wrapped with a layer of plastic film to play the role of moisture-proof, dust-proof, and oil-proof. Each reel of cable is clearly marked with product name, model specification, length, weight, production date, implementation standard, manufacturer, and other information on the side of the cable reel, which is convenient for customers to identify and count. The packaging is also printed with warning signs such as "Do not invert", "Handle with care", "Moisture-proof and sun-proof" to remind relevant personnel to pay attention to protection.
For short-length cables, they are packaged in rolls, tightly wrapped with plastic film and then put into cartons. The cartons have high strength, which can effectively prevent the cables from being damaged by pressure, and the necessary product information is also marked on the outside of the cartons.
(2) Transportation
Transportation methods: Select appropriate transportation methods according to the transportation distance and order quantity. For short-distance transportation, road transportation is generally used, and trucks are used to load cable reels. The trucks need to be equipped with fixing devices to firmly fix the cable reels to prevent shaking during transportation. For long-distance transportation, railway transportation can be selected, which has good stability and is suitable for transporting large quantities of cables; for areas with ports, waterway transportation can also be used, with relatively low cost.
Transportation precautions: During transportation, the cable reel must be placed horizontally, and it is strictly forbidden to tilt or invert to prevent the cable from slipping off the cable reel. A certain distance should be kept between cable reels to prevent mutual collision and extrusion, which may cause damage to the sheath and internal structure. Transport vehicles or tools should take rain-proof, sun-proof, and dust-proof measures, such as covering with rain-proof cloth, to avoid the cable being damped, polluted, or exposed to direct sunlight. When loading and unloading the cable reel, special hoisting equipment must be used, and 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 transportation, traffic rules must be observed, driving should be smooth, and operations such as sudden braking and sharp turns should be avoided to reduce the impact on the cable.
