I. From the Perspective of the Product Itself
(I) Specification Parameters
4X95mm² Specification
The 4X95mm² specification of Na2xy-J 0.6/1kV XLPE
Insulated Cable has a rated voltage of 0.6/1kV and belongs to the category of low-voltage
Distribution Cables. It has a four-core design, with each conductor having a cross-sectional area of 95mm². This four-core structure can well adapt to the three-phase four-wire distribution system, capable of transmitting three-phase current and neutral line current simultaneously, ensuring the balanced and stable operation of the power system.
In terms of current-carrying capacity, this specification of cable performs excellently. When laid in the air, the long-term allowable current-carrying capacity is approximately 240A; when laid in the soil, due to the relatively better heat dissipation conditions of the soil, the long-term allowable current-carrying capacity can reach about 280A. The large current-carrying capacity enables it to meet the needs of high-power power transmission.
The thickness of the cable's insulation layer is 1.4mm, which can effectively block current, ensuring that the cable has good insulation performance under the rated voltage and preventing potential safety hazards such as electric leakage. The outer diameter of the cable is about 48mm, and this size provides certain
Flexibility in construction, whether for pipe laying or direct burial.
The bending radius is an important parameter during cable installation. For this specification of cable, the static bending radius is not less than 12 times the outer diameter of the cable, and the dynamic bending radius is not less than 20 times the outer diameter of the cable. This requires that during installation, excessive bending should be avoided to prevent damage to the internal structure of the cable and affect its performance.
4X50mm² Specification
This specification of cable also has a rated voltage of 0.6/1kV, with a four-core structure, and each conductor has a cross-sectional area of 50mm². Compared with the 4X95mm² specification, its current-carrying capacity is relatively smaller. When laid in the air, the long-term allowable current-carrying capacity is approximately 160A; when laid in the soil, it is about 190A, suitable for medium-power power transmission scenarios.
The insulation layer thickness is 1.2mm, which can meet the insulation requirements of the 0.6/1kV voltage level and ensure the stable electrical performance of the cable. The outer diameter of the cable is about 38mm, which is slimmer than the 4X95mm² specification, providing more advantages in some space-constrained laying environments.
In terms of bending radius, the static bending radius is not less than 10 times the outer diameter of the cable, and the dynamic bending radius is not less than 15 times the outer diameter of the cable. During installation, operations should be carried out in accordance with this standard to ensure the service life and performance of the cable.
(II) Characteristic Uses
4X95mm² Specification
Industrial equipment clusters are one of the important application scenarios for this specification of cable. In large factories, manufacturing workshops and other places, there are often a large number of high-power industrial equipment, such as large machine tools, heavy machinery, production lines, etc. These equipment have a large and stable demand for electricity. The 4X95mm² specification cable, with its large current-carrying capacity, can provide sufficient and stable power support for these equipment, ensuring the smooth progress of production.
Large commercial buildings are also its main application areas. Large shopping malls, office buildings, hotels and other commercial buildings contain numerous electrical equipment, such as central air conditioning systems, elevators, lighting systems, various commercial appliances, etc., with a large overall power load. This specification of cable can be used as the main distribution line to efficiently transmit electricity from the distribution room to various floors and areas, meeting the complex and diverse electricity needs of commercial buildings and ensuring the normal conduct of various commercial activities.
In addition, in some large public facilities, such as stadiums, convention and exhibition centers, etc., when large-scale events are held, the power demand surges, and the 4X95mm² specification cable can also undertake the power transmission task, ensuring the normal operation of various equipment in the facilities.
4X50mm² Specification
Power distribution in small and medium-sized buildings is a typical application scenario for this specification of cable. For small and medium-sized buildings such as small office buildings, residential communities, and small shopping malls, their overall power load is relatively moderate, and the current-carrying capacity of the 4X50mm² specification cable can meet the power distribution needs of such buildings. It can distribute electricity from the distribution room to various units or areas, providing stable power for lighting, household appliances, office equipment, etc.
This specification of cable also plays an important role in branch transmission. In large distribution systems, after the main line transmits electricity to each junction box, it is necessary to further distribute electricity to specific electrical equipment or areas through branch cables. The 4X50mm² specification cable, with its moderate size and matched current-carrying capacity, is very suitable as such a branch
Transmission Cable, ensuring efficient and safe transmission of electricity in each branch.
At the same time, some small industrial workshops, processing plants, etc., due to the relatively small power of their production equipment, the 4X50mm² specification cable can also meet their daily production power needs.
(III) Material and Style
Conductor Material
The conductors of both specifications of cables are made of aluminum (Al). Although the conductivity of
Aluminum Conductors is slightly lower than that of
Copper Conductors, they have obvious advantages. Firstly, aluminum has a low density, making the overall weight of the cable lighter, which is more convenient during transportation and installation, and can reduce construction difficulty and cost. Secondly, aluminum resources are relatively abundant, and its price is lower than that of copper. Using
Aluminum Conductors can effectively reduce the production cost of the cable, improve the cost performance of the product, and balance economy and practicality.
Insulation Layer Material
The insulation layer is made of cross-linked polyethylene (XLPE). XLPE is a polyethylene material that has undergone cross-linking treatment and has excellent performance. It has good temperature resistance, with a long-term service temperature of up to 90℃. In abnormal situations such as short circuits, it can maintain certain insulation performance at higher temperatures, improving the safety and reliability of the cable. At the same time, XLPE has stable insulation performance, high insulation resistance, and low dielectric loss, which can effectively prevent current leakage and ensure the efficiency of power transmission. In addition, XLPE also has good anti-aging performance and mechanical strength, which can resist the influence of external environmental factors and extend the service life of the cable.
Sheath Material
The sheath is made of polyvinyl chloride (PVC). PVC material has good corrosion resistance, which can resist the erosion of chemical substances in the soil, moisture, sunlight, ultraviolet rays and other external factors, protecting the internal conductor and insulation layer of the cable from damage. It has high mechanical strength, certain impact resistance and tensile capacity, and can provide effective protection for the internal structure during cable laying and use. Moreover, the
PVC Sheath has good processability, is easy to produce and process into various shapes, and has a relatively low cost.
Style Design
Both cables are cylindrical in overall shape with a compact structure. The four-core conductors are twisted together, and the outside is sequentially wrapped with an XLPE insulation layer and a PVC sheath, forming a solid whole. The color of the cable is usually black, which has good dirt resistance and can maintain a relatively clean appearance in various laying environments. At the same time, black can also absorb heat to a certain extent, reducing the impact of temperature changes on cable performance. The surface of the cable is smooth and flat, without obvious protrusions or depressions, facilitating operations such as pipe threading and dragging during construction.
(IV) Production Process
Conductor Production
First, the aluminum ingot is smelted to remove impurities, obtaining aluminum water that meets the purity requirements. Then, the aluminum water is cast into aluminum rods through a continuous casting process, and the diameter of the aluminum rods is adjusted according to the specifications of the
Cable Conductor. Next, the aluminum rod is drawn into
Aluminum Wires of the required diameter by a wire drawing process. During the wire drawing process, it is necessary to accurately control the drawing speed, temperature and lubrication conditions to ensure the dimensional accuracy and mechanical properties of the
Aluminum Wire. For cables of 4X95mm² and 4X50mm² specifications, multiple aluminum wires are twisted according to a certain twisting method. Twisting can improve the flexibility and filling coefficient of the conductor, reduce the skin effect, and ensure the conductive performance of the conductor.
Insulation Layer Extrusion
The extrusion molding process is used to wrap the XLPE insulation layer around the conductor. First, XLPE granular material is added to the hopper of the extruder. After being heated and melted, the molten XLPE material is transported to the mold through the screw of the extruder. The size of the mold is accurately designed according to the cable specifications to ensure uniform thickness of the insulation layer. During the extrusion process, the extrusion temperature (generally between 130-190℃), extrusion speed and pressure are strictly controlled, so that the molten XLPE material evenly coats the surface of the conductor to form a continuous and dense insulation layer. After extrusion, the insulation layer is cross-linked, usually by peroxide cross-linking. By heating, the XLPE molecules form a three-dimensional network structure, thereby significantly improving its heat resistance, mechanical strength and insulation performance.
Cabling Process
The four
Insulated Cores are cabled. The four cores are twisted together according to a certain twisting direction and pitch. The size of the twisting pitch will affect the flexibility and structural stability of the cable, and needs to be reasonably set according to the cable specifications. During the twisting process, in order to ensure the roundness and filling rate of the cable, some inert filling materials, such as polypropylene ropes, are filled between the four cores. The filling material can also play a buffering role, reducing mutual friction and extrusion between the cores and protecting the insulation layer from damage.
Sheath Extrusion
A PVC sheath is extruded on the outer layer of the cabled cable. PVC material is added to the extruder, heated and melted, and then evenly coated on the outer layer of the cabled cable through an extrusion mold. The extrusion parameters are controlled to ensure that the sheath has uniform thickness, a smooth surface, and is tightly combined with the internal cabling structure without defects such as bubbles and impurities. The extrusion of the PVC sheath can further enhance the mechanical protection performance and environmental erosion resistance of the cable.
Quality Inspection
Strict quality inspection is carried out in each link of the production process. For the conductor, parameters such as its diameter, resistivity, and tensile strength are tested; for the insulation layer, properties such as its thickness, insulation resistance, voltage resistance, and thermal elongation are tested; for cabling and sheathing, the appearance, size, roundness, and the tensile strength and elongation at break of the sheath are tested. The finished cable also needs to undergo partial discharge tests, aging tests, etc., to ensure that the product meets the relevant standards and technical requirements of the 0.6/1kV voltage level. Only cables that pass all tests can leave the factory for sale.
II. From the Perspective of General Product Information
(I) Packaging
Packaging Materials
Both specifications of Na2xy-J 0.6/1kV
XLPE Insulated Cables are packaged with cable reels. According to the length and weight of the cable, wooden cable reels and steel cable reels are selected respectively. For 4X95mm² specification cables with longer length and greater weight, steel cable reels are usually used. Steel cable reels have high strength and strong bearing capacity, can bear the weight of the cable, and are suitable for long-distance transportation and multiple turnover uses. The 4X50mm² specification cable, being relatively lightweight, can use wooden cable reels, which have low cost and can also meet the needs of medium and short-distance transportation and storage.
Packaging Method
When packaging, the cable is neatly wound on the cable reel. During the winding process, it is necessary to ensure that the cable is arranged tightly and flatly, avoiding twisting, crossing and overlapping, so as to prevent the cable from being squeezed, worn or otherwise damaged during transportation and storage. The outermost layer of the cable is wrapped with a plastic film, which has good moisture-proof and dust-proof performance and can protect the cable from moisture, dust and other pollutants in the external environment. For wooden cable reels, baffles are added on their sides to prevent the cable from slipping off; the steel cable reel itself has a solid structure, and the baffles on the sides can effectively play a protective role. A shaft sleeve is installed at the central shaft hole of the cable reel to facilitate handling and loading/unloading with equipment such as forklifts and cranes.
Packaging Marks
Relevant product information is clearly and firmly marked on the side and end face of the cable reel, including product name (Na2xy-J 0.6/1kV XL
PE Insulated Cable), specification parameters (4X95mm² or 4X50mm²), length, rated voltage, implementation standard, production date, production batch number, manufacturer's name, address, contact information, etc. These marks not only facilitate users to identify product information when receiving and inspecting the cable, but also are conducive to product traceability and quality management.
(II) Transportation
Transportation Mode
Different transportation modes can be selected according to the transportation distance, quantity of cables and customer needs. For long-distance transportation with large quantities, railway transportation is a more suitable choice. Railway transportation has large transport capacity, low cost and stable transportation process, which can effectively ensure the safety of the cable. For medium and short-distance transportation, road transportation can be adopted. Road transportation has high flexibility and can realize door-to-door service, facilitating customers to receive goods. For urgent orders or small batches of sample transportation, air transportation can also be used. Although the cost is higher, it can greatly shorten the transportation time.
Transportation Precautions
Before transportation, carefully check the packaging of the cable to ensure that the cable reel is intact, the cable is tightly wound, and the plastic film is tightly wrapped. During transportation, the cable reel must be placed horizontally, and tilting, inverting or stacking are strictly prohibited to prevent the cable reel from rolling and colliding, which may cause damage to the cable. The transport vehicle should drive smoothly, avoiding violent operations such as sudden braking and sharp turns, to reduce the shaking of the cable reel. At the same time, measures should be taken to prevent rain, sun and moisture. A rain cloth can be covered on the cable reel to avoid the cable being soaked by rain, exposed to the sun or damp, which may affect the performance of the cable. When loading and unloading the cable, special lifting equipment such as cranes and forklifts must be used. During loading and unloading, handle with care to avoid impact and damage to the cable and cable reel.
Transportation Fixation
To prevent the cable reel from moving and rolling during transportation, it is necessary to fix it firmly. Steel wire ropes, iron chains, etc. can be used to tightly fix the cable reel on the carriage of the transport vehicle. The fixed points should be selected at the solid parts of the cable reel, such as the flange of the steel reel or the reinforcing ribs of the wooden reel, to ensure reliable fixation. For long-distance transportation, buffer materials such as wooden boards and rubber pads can also be placed between the cable reels to reduce mutual collision and friction between the cable reels.
