I. From the Perspective of the Product Itself
(I) Specification Parameters
This 0.6/1kv pure copper XLPE insulated single - core
Power Cable has clear and detailed specification parameters, which can accurately meet the needs of different power consumption scenarios. It covers three wire diameter specifications: 120mm², 250mm² and 400mm², and is suitable for 0.6/1kv voltage level.
The wire diameter specification is a key factor determining the current - carrying capacity of the cable. The 120mm² cable has a safe current - carrying capacity that can meet the power demand of small and medium - power equipment. Tests show that it can carry a current of about 200 - 250A in a normal environment. The 250mm² cable has a stronger current - carrying capacity, which can carry a current of about 300 - 350A and cope with medium and high - power scenarios. The 400mm² cable has the most prominent current - carrying capacity, which can carry a current of about 450 - 500A, and is fully suitable for high - voltage and large - current requirements such as outgoing lines of large transformers.
The 0.6/1kv voltage level means that the cable can be used in power systems with a rated voltage of 1kv and below. This characteristic determines its wide applicability in the field of industrial and civil power distribution. At the same time, the thickness of the cable's insulation layer varies with the wire diameter. The thickness of the XLPE insulation layer of the 120mm² cable is about 1.4mm, that of the 250mm² cable is about 1.8mm, and that of the 400mm² cable is about 2.0mm. This thickness design can ensure effective insulation under their respective current - carrying and voltage conditions. The outer diameter of the cable increases with the increase of the wire diameter. The outer diameter of the 120mm² cable is about 15mm, that of the 250mm² cable is about 20mm, and that of the 400mm² cable is about 25mm. It not only ensures structural stability but also takes into account the convenience of laying.
With its excellent performance, this cable has a variety of characteristic uses in the field of industrial and civil power distribution.
In commercial buildings, the 120mm² cable is an ideal choice for power distribution branches. The power load of lighting systems and small office equipment in commercial buildings is relatively small, and the current - carrying capacity of the 120mm² cable can just meet the power demand of these equipment. It can extend from the main distribution box of the building to the distribution boxes on each floor, providing stable power for various equipment in the floor. Moreover, the single - core structure makes it more convenient to lay in narrow spaces such as building walls and ceilings.
The production lines in industrial parks have high requirements for power supply, and the 250mm² cable can well meet their needs. The power of equipment such as motors and conveyors in the production line is relatively large, and the current - carrying capacity of the 250mm² cable is sufficient to support the normal operation of these equipment, ensuring that the production line will not be interrupted due to insufficient power supply. At the same time, the environment of the industrial park may have certain dust and temperature changes, and the XLPE insulation layer of the cable can resist the impact of these environmental factors, ensuring long - term stable operation.
The outgoing lines of large transformers need cables that can carry high - voltage and large - current, and the 400mm² cable is just suitable for this scenario. As an important equipment in the power system, the stability of power transmission of transformer outgoing lines is crucial. The 400mm² cable can efficiently transmit power from the transformer to the subsequent power distribution system, reducing power loss. In addition, the 400mm² cable can also play an important role in the main lines of urban power distribution networks, providing guarantee for power supply in large areas.
In addition to the above main scenarios, the cable can also be used for power supply of central air - conditioning systems in large shopping malls and important medical equipment in hospitals. In these scenarios, the safety and stability of the cable can be fully reflected.
(III) Material and Style
The material selection and style design of the cable fully consider the performance and use needs, making it perform well in various environments.
In terms of materials, the conductor is made of pure copper. Pure copper has a very high conductivity, which greatly reduces the loss of power during transmission and improves the efficiency of power transmission. Compared with conductors of other materials,
Pure Copper Conductors have better chemical stability, are not easy to oxidize, can maintain good conductivity for a long time, and extend the service life of the cable. Moreover, pure copper has good ductility and toughness, and is not easy to break during the processing and laying of the cable, ensuring the structural integrity of the cable.
The insulation layer is made of XLPE (cross - linked polyethylene) material. XLPE has excellent temperature resistance and can work stably in the temperature range of - 40℃ to 90℃. Even in high - temperature environments, there will be no problems such as insulation aging and cracking. At the same time, it has excellent insulation performance, which can effectively isolate the current under 0.6/1kv voltage and prevent electric leakage accidents. XLPE also has good chemical corrosion resistance, which can resist the erosion of complex environmental factors such as moisture, oil stains and dust, further ensuring the safe operation of the cable.
In terms of style, the cable adopts a single - core design. This design makes the cable more flexible and can be bent flexibly during laying, especially suitable for installation in narrow spaces and complex paths. The single - core structure also reduces the volume of the cable and saves the laying space. The cable has a cylindrical appearance and a smooth surface. This style is not only convenient for storage and transportation, but also can reduce friction with other objects during laying, reducing the risk of damage. In addition, the color of the cable is usually black, which has good dirt resistance and can to a certain extent cover the stains generated during use, keeping the appearance clean.
(IV) Production Process
The production process of the cable adopts advanced and rigorous technology, and each link is strictly controlled to ensure product quality.
In the production of pure
Copper Conductors, high - purity electrolytic copper is first selected as the raw material, with a purity of more than 99.95%. The copper material is drawn into
Copper Wires of the required diameter through a continuous wire drawing process. During the wire drawing process, the wire drawing speed and die precision are strictly controlled to ensure that the diameter of the copper wire is uniform and the deviation does not exceed the specified range. The drawn copper wire is annealed, and heated and cooled under specific temperature and time conditions to improve the mechanical properties of the copper wire, enhance its
Flexibility and ductility, so that the copper wire is not easy to break in the subsequent processing and use.
The XLPE insulation layer is made by extrusion cross - linking process. First, the XLPE raw material is pretreated to remove moisture and impurities to ensure the quality of the insulation layer. Then, the treated raw material is added to the extruder, heated to a molten state in the extruder, and the molten XLPE is evenly coated on the surface of the copper conductor through a die to form an insulation layer. During the extrusion process, the extrusion temperature, pressure and speed are accurately controlled to ensure that the insulation layer has a uniform thickness, a smooth surface, and no bubbles or cracks. After extrusion, the cable is cross - linked, and the XLPE molecules form a three - dimensional network structure through high temperature and high pressure, thereby significantly improving the temperature resistance, mechanical strength and insulation performance of the insulation layer.
In the cooling and solidification process of the cable, the cable with the just extruded insulation layer has a high temperature and needs to be cooled through a cold water tank to make the insulation layer solidify and form quickly. During the cooling process, the water temperature and cooling speed are controlled to avoid cracks in the insulation layer due to uneven cooling. After cooling, the cable is tested by a spark tester, and the insulation layer is scanned by high - voltage sparks to check for defects such as pinholes in the insulation layer, ensuring that the insulation performance meets the standard.
Finally, the cable is measured and cut to length, and sealed heads are added at both ends of the cable to prevent moisture and impurities from entering. At the same time, sampling tests are carried out on the finished cables, including conductivity, insulation performance, temperature resistance and other indicators. Only products that meet all standards can leave the factory.
(V) Product Performance Advantages
In addition to the above aspects, the cable also has many outstanding performance advantages. It has excellent anti - aging performance. Due to the use of high - quality pure
Copper Conductors and XLPE insulation layers, as well as advanced production technology, the cable can resist the impact of oxidation, ultraviolet rays, temperature changes and other factors during long - term use. The insulation layer is not easy to have aging phenomena such as hardening and cracking, and the conductor is not easy to be corroded, with a service life of more than 30 years.
In terms of mechanical properties, the cable has high tensile strength and compressive strength. During laying and use, it can bear a certain tension and pressure, and is not easy to break or deform. At the same time, the cable has good wear resistance, which can resist friction with the ground, pipes and other objects, reducing damage caused by friction.
The fire - proof performance of the cable is also worth mentioning. The XLPE insulation layer has a certain flame retardancy. When encountering an open flame, it can delay the burning speed, and produce less smoke and low emissions of toxic gases, which can buy time for personnel evacuation and fire fighting.
In addition, the installation convenience of the cable is also one of its advantages. The single - core structure makes the bending radius of the cable small, and it can be easily laid in narrow spaces. Moreover, the weight of the cable is relatively light, making the handling and installation process more labor - saving.
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, taking into account both the protection function and convenience.
The cable is packaged in a reel type, and the cable is neatly wound on a high - strength wooden or plastic reel. The diameter of the reel is determined according to the length and wire diameter of the cable. The 120mm² cable is usually wound on a reel with a diameter of 600mm, the 250mm² cable on a reel with a diameter of 800mm, and the 400mm² cable on a reel with a diameter of 1000mm. This design can prevent the cable from being twisted or knotted during transportation and storage. Solid baffles are set on both sides of the reel, and the height of the baffles is higher than the winding height of the cable, which can effectively block the collision and extrusion of external objects on the cable.
A layer of moisture - proof paper and pearl cotton buffer layer is laid between the cable and the reel. The moisture - proof paper can prevent moisture in the air from invading the cable, and the pearl cotton can reduce the vibration and friction of the cable during transportation, protecting the cable surface from wear. 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, 250mm², 400mm²), voltage level (0.6/1kv), 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, specifications and transportation distance of the cable. For a small amount of short - distance transportation, road transportation is adopted, and the transport vehicles are trucks with rain shelters and fixing devices. When loading, the cable reels are fixed in the carriage to prevent rolling and collision during transportation. During transportation, avoid the cable being exposed to the sun, rain and severe bumps, and the driver should regularly check the fixing of the goods.
For a large amount of long - distance transportation, railway transportation is adopted. Railway transportation has the characteristics of high stability and large transportation capacity, which can effectively reduce the risk of goods damage during transportation. When loading cables, the loading position is reasonably arranged in accordance with the regulations of railway transportation to ensure that the goods are placed neatly and stably and meet the loading requirements.
For export transportation, sea transportation is mainly adopted. Sea transportation is suitable for long - distance transportation of large quantities of goods with relatively low cost. During sea transportation, the packaging of the cable must meet international transportation standards, with strong pallets and rain covers added to prevent seawater erosion and goods extrusion. At the same time, go through all export procedures in advance to ensure that the goods can pass customs smoothly.
During transportation, the goods are tracked throughout the process, and the location and status of the goods are mastered in real time through the logistics information system. In case of special weather, traffic jams and other situations, communicate with the transportation company in time to adjust the transportation route and time to ensure that the goods are delivered on time. If there is any problem such as goods damage during transportation, coordinate and handle it in time to protect the rights and interests of customers.
