I. From the Perspective of the Product Itself
(I) Specification Parameters
This under
Ground Cable has clear and detailed settings in terms of specification parameters, which can accurately meet the power demand of different underground laying scenarios. It covers various wire diameter specifications such as 120mm², 185mm² and 400mm², and adopts a 4-core with earth design.
The difference in wire diameter specifications directly determines the current-carrying capacity of the cable. The 120mm² cable has a moderate current-carrying capacity, which can meet the power demand of small and medium-power equipment and areas. Its safe current-carrying capacity can be adapted to scenarios such as underground distribution branches in residential quarters; the 185mm² cable has a stronger current-carrying capacity and is suitable for medium and high-power equipment, such as underground power supply lines for medium-sized production equipment in industrial parks; the 400mm² cable has the most prominent current-carrying capacity and can meet the transmission needs of large underground power main lines, such as urban underground main distribution lines.
In the 4-core with earth design, the
4 Cores are respectively used for power transmission of different phases to ensure stable transmission of three-phase electricity, while the
Earth Wire plays a safety protection role. Its cross-sectional size matches the main core, and it can quickly conduct current away in case of electric leakage to ensure electricity safety.
In addition, parameters such as the thickness and outer diameter of the cable's insulation layer are also accurately calculated. The thickness of the XLPE insulation layer is adjusted according to different wire diameters. The thickness of the insulation layer of the 120mm² cable can ensure effective insulation within its current-carrying range, and the insulation layer thickness of the 185mm² and 400mm² cables is also adapted to it to meet their respective current-carrying needs. The outer diameter of the cable takes into account the space adaptability and structural stability during underground laying. It will not be too thick to increase the laying difficulty, nor too thin to affect the overall strength.
With its unique performance, the cable has distinctive uses in many fields.
In urban municipal engineering, it is an important part of the underground power distribution system. This cable can be used for street lamp power supply lines under urban roads and power supply for underground parking lots. Municipal engineering has high requirements for the reliability and safety of cables. This cable can work stably in the underground humid and gravel-rich environment to ensure the normal power consumption of municipal facilities. For example, in urban road reconstruction projects, 120mm² or 185mm² cables are used as underground power supply lines for street lamps and surrounding facilities, which can effectively avoid the impact of the external environment on power transmission.
In terms of industrial parks, there are a large number of production equipment in industrial parks, and most of these equipment need
Underground Cables for power supply. For medium-sized production equipment, 185mm² cables can meet their power needs; while 400mm² cables can be used for the main power supply lines of large production lines. The underground environment of industrial parks may have certain industrial pollutants, and the corrosion resistance of the cable can resist the erosion of these pollutants to ensure the continuous power supply of production equipment.
In the construction of residential quarters, this cable can be used for the underground power distribution system of the community and the lighting and power supply of underground garages. The 120mm² cable is suitable for distribution branches in the community to supply power to some electrical equipment in residential buildings; the 185mm² cable can be used as the main distribution branch of the community to meet the overall power demand of multiple residential buildings. Its safe and reliable performance can ensure the electricity safety of residents and reduce the occurrence of power failures.
In addition, this cable can also be found in the underground power supply systems of some large public facilities, such as gymnasiums and exhibition centers. It can adapt to the complex underground environment of these places, provide stable power support for various electrical equipment, and ensure the normal operation of public facilities.
(III) Material and Style
The material selection of the cable fully considers the characteristics of the underground laying environment, and the style design is also suitable for underground installation needs.
In terms of materials, the insulation layer is made of XLPE (cross-linked polyethylene), which has many excellent characteristics. It has excellent temperature resistance and can maintain stable performance in the large temperature difference changes of the underground environment, and will not affect the insulation effect due to too high or too low temperature. At the same time, XLPE material has large insulation resistance and stable insulation performance, which can effectively prevent electric leakage and ensure the safety of power transmission.
The outer layer is made of PVC material, which has good corrosion resistance and can resist the erosion of acid-base substances and moisture in the underground soil, prolonging the service life of the cable. Moreover, PVC material has high mechanical strength and certain wear resistance, and can withstand friction with soil and gravel without being easily damaged during underground laying.
In terms of style, the cable adopts an unarmoured design, which gives the cable good
Flexibility. During underground laying, it can adapt to complex terrain and curved paths, facilitating construction operations. The cable is cylindrical as a whole with a regular appearance and smooth surface. This style can not only reduce the resistance during laying but also reduce the risk of being hooked and damaged by underground debris. The 4-core with earth structure is reasonably arranged and neatly arranged inside the cable to ensure the stability of power transmission.
(IV) Production Process
The production process of this cable is exquisite and rigorous, and every link is strictly controlled to ensure that the product can adapt to the complex underground environment.
In the production process of the conductor, high-purity copper is selected as the raw material. The copper material is drawn into
Copper Wires of the required diameter through a wire drawing process. During the wire drawing process, the wire drawing speed and die precision are strictly controlled to ensure the uniform diameter of the copper wires. Then, multiple copper wires are stranded to form a conductor. The stranding process can enhance the flexibility and mechanical strength of the conductor, making it not easy to break during laying. The surface of the
Stranded Conductor is treated to remove impurities and burrs to ensure the tight bonding of the subsequent insulation layer.
The XLPE insulation layer is made by extrusion cross-linking process. First, the XLPE raw material is pretreated to remove moisture and impurities. Then, the raw material is added to the extruder, melted at a suitable temperature, and evenly coated on the surface of the conductor through a die to form an insulation layer. During the extrusion process, temperature, pressure and speed are accurately controlled to ensure uniform thickness and smooth surface of the insulation layer. After extrusion, the cable is cross-linked. Through high temperature and high pressure, XLPE molecules form a three-dimensional network structure, thereby improving the temperature resistance, mechanical strength and insulation performance of the insulation layer, enabling it to work stably for a long time in the underground humid environment.
The outer
PVC Sheath is also made by extrusion process. The PVC raw material is heated and melted, then extruded and coated on the outside of the XLPE insulation layer. During the extrusion process, process parameters are strictly controlled to ensure uniform thickness of the sheath, tight bonding with the insulation layer, and no bubbles or wrinkles. Anti-aging and corrosion-resistant additives are added to the production of PVC sheaths to further enhance their ability to adapt to the underground environment.
In the cabling process, the
4 Cores and the earth wire are arranged according to the specified structure and stranded by a cabling machine. Proper tension is maintained during stranding to ensure that the cable structure is compact and round. The cabled cable is cooled and solidified to make its structure more stable.
Finally, the cable will undergo strict testing, including insulation performance testing, voltage resistance testing, mechanical performance testing, etc. Only products that meet the standards in all indicators can leave the factory.
(V) Product Performance Advantages
In addition to the above aspects, the cable also has many excellent performance advantages. It has outstanding compressive performance and can withstand the pressure of underground soil and external pressure generated by passing vehicles, and will not suffer structural damage or performance degradation due to compression.
Aging resistance is also one of its highlights. Due to the use of high-quality XLPE and PVC materials and advanced production technology, the cable is not easy to have problems such as insulation layer aging and sheath cracking in the underground environment with high humidity and large temperature difference, and has a long service life.
In terms of waterproof performance, the XLPE insulation layer and PVC sheath of the cable are closely combined, which can effectively block the intrusion of moisture. Even in the environment with high underground water level, it can maintain stable insulation performance and avoid affecting power transmission due to water ingress.
In addition, the cable has high transmission efficiency. The conductor is made of high-purity copper, which has low resistance and low loss during power transmission, which can improve the utilization efficiency of power.
II. From the Perspective of General Product Information
(I) Packaging
In order to ensure that the cable is not damaged during transportation and storage, the packaging design is scientific and reasonable, fully considering the characteristics of the product and transportation needs.
The cable is packaged in a reel type, and the cable is neatly wound on a solid wooden or metal reel. The diameter of the reel is determined according to the length and wire diameter of the cable to ensure that the cable is wound tightly without loosening or twisting. Baffles are installed on both sides of the reel, and the height of the baffles is higher than the winding height of the cable, which can effectively prevent other items from colliding and squeezing the cable during transportation.
A layer of moisture-proof paper and soft buffer material, such as pearl cotton, is laid between the cable and the reel. The moisture-proof paper can prevent moisture in the air from invading the cable, and the buffer material can reduce the vibration and friction of the cable during transportation and protect the cable surface from damage. For long-distance transportation or storage in a relatively humid environment, a layer of waterproof plastic film is wrapped around the outer layer of the cable to further enhance the moisture-proof effect.
The packaging clearly marks the relevant information of the product, including product name, specifications (120mm², 185mm², 400mm²), length, production batch number, production date, manufacturer name and contact information, etc. At the same time, warning signs such as "Moisture-proof", "Handle with care" and "Do not press heavily" are also marked to remind transportation and storage personnel to pay attention to relevant matters.
(II) Transportation
The transportation link is strictly standardized to ensure that the cable can be delivered to the destination safely and timely.
In terms of domestic transportation, appropriate transportation methods are selected according to the quantity, specification and transportation distance of the cable. For a small amount of short-distance transportation, road transportation is adopted. The transport vehicles are equipped with special fixing devices to fix the reels wrapped with cables firmly to prevent rolling and collision during transportation. During transportation, avoid the cable being exposed to the sun, rain and severe bumps.
For a large amount of long-distance transportation, railway transportation is adopted. Railway transportation has high stability and can reduce the impact of vibration during transportation on the cable. When loading cables, reasonably arrange the loading position to ensure that the goods are placed neatly and stably to avoid mutual extrusion.
During transportation, the goods are tracked throughout the process, and the transportation status of the goods is mastered in real time through the logistics information system.
