(I) Specification Parameters
The copper conductor cross - linked polyethylene (XLPE) insulated
Power Cables involved this time mainly include three models: YJV, R2V, and RO2V, as well as three conductor cross - sectional specifications: 4×10mm², 4×16mm², and 4×25mm².
In terms of conductor cross - sectional specifications, these three specifications all have a 4 - core structure. 4×10mm² means that the cable consists of
4 Cores with a cross - sectional area of 10mm²; 4×16mm² is
4 Cores of 16mm²; 4×25mm² is 4 cores of 25mm². The cross - sectional area of the core is directly related to the current - carrying capacity of the cable. The larger the cross - sectional area, the greater the current - carrying capacity and the more electricity that can be transmitted.
The current - carrying capacity of a 10mm² cable is relatively small, usually around 30 - 50A, and it is suitable for power distribution of small - sized equipment, such as power supply for small household appliances in homes and power connection for small office equipment. The current - carrying capacity of a 16mm² cable is generally 40 - 70A, which can meet the power transmission needs of medium - sized loads, such as power supply for medium - sized industrial motors and small central air conditioners. The current - carrying capacity of a 25mm² cable can reach 60 - 100A, which is suitable for high - power scenarios, such as the main power distribution lines of large industrial equipment and large commercial places, and can stably transmit electricity to ensure the normal operation of the equipment.
These three models of cables all use copper as the conductor. Copper has excellent conductivity and high conductivity, resulting in less energy loss during power transmission. At the same time, they all use cross - linked polyethylene (XLPE) as the
Insulation Material.
XLPE Insulation Material has excellent insulation performance, which can effectively isolate current and prevent electric leakage. Its temperature resistance is also outstanding, and it can work normally in an ambient temperature range of - 40℃ to 90℃, being able to adapt to different temperature conditions.
(II) Characteristic Uses
Based on the above specification parameters and performance characteristics, these copper conductor
XLPE Insulated Power Cables are widely used in many fields.
In terms of building power distribution, cables of different specifications have their own roles. The 4×10mm² cable is often used for branch power distribution in residential buildings, such as connecting sockets and lighting in various rooms and other small electrical equipment, which can meet the needs of daily household electricity use. The 4×16mm² cable can be used for the main power distribution lines of residences or power distribution in small commercial buildings, providing power support for electrical equipment in multiple rooms or small commercial areas. The 4×25mm² cable is suitable for the main power distribution lines of large commercial buildings and high - rise buildings, ensuring stable power supply for the entire building.
Power supply for industrial equipment is also an important application scenario. For small industrial equipment, such as small machine tools and small fans, the 4×10mm² cable can meet their power needs. For medium - sized industrial equipment, such as medium - sized compressors and medium - sized water pumps, the 4×16mm² cable is a more suitable choice. For large industrial equipment, such as large injection molding machines and large production lines, the 4×25mm² cable can provide sufficient and stable power to ensure the normal operation of the equipment.
Due to its excellent electrical performance and aging resistance, YJV cables are widely used in places with high requirements for cable performance, such as hospitals and data centers. These places have extremely high requirements for the stability and safety of power supply, and YJV cables can effectively reduce the probability of failures.
R2V Cables may be widely used in ordinary industrial and construction scenarios. Their performance can meet general power transmission needs, and they have relatively high cost - effectiveness.
RO2V Cables may have better weather resistance, so they have more advantages in outdoor laying scenarios, such as power supply for outdoor billboards and outdoor lighting systems, and can resist the impact of natural environments such as wind, sun, and rain.
(III) Material and Style
In terms of materials, these three models of cables have the same core materials, but there are also certain differences.
They all use copper as the conductor. Copper is an excellent conductive material with extremely high conductivity, which can transmit electricity efficiently and reduce energy loss. At the same time, copper also has good ductility and toughness, and is not easy to break during the production and laying of cables, making it easy to process and install.
The insulation layer is made of cross - linked polyethylene (XLPE) material. XLPE is a network structure formed by cross - linking polyethylene molecules through chemical or physical methods. This structure enables XLPE to have excellent insulation performance, which can withstand high voltage and effectively prevent insulation breakdown. Moreover, XLPE has good temperature resistance, will not soften at high temperatures, can maintain a stable insulation effect, and also has strong aging resistance, so it has a long service life.
In terms of sheath materials, different models of cables may vary. The sheath of YJV cables is polyvinyl chloride (PVC). The
PVC Sheath has good mechanical properties, impact resistance, and wear resistance, and can effectively protect the inner cores and insulation layers of the cable. At the same time, the PVC sheath also has a certain degree of chemical corrosion resistance and can adapt to some environments with mild chemical pollution.
The sheath materials of R2V and RO2V cables may also be polyvinyl chloride, but there may be differences in formulas or processes to meet different usage needs. In order to have better weather resistance, the sheath of RO2V cables may be added with anti - ultraviolet and anti - aging additives, so that they can maintain good performance in outdoor environments.
In terms of style, these three types of cables all have a circular multi - core structure. The circular structure has low resistance during laying, making it more convenient and fast for both pipe laying and direct burial laying. The integration of multiple cores not only facilitates the installation and management of construction personnel but also reduces the space occupied by cables during laying, making the line arrangement more neat and orderly. The appearance of the cable is usually dark colors such as black or gray. This color is not easy to get dirty and can also absorb heat to a certain extent, reducing the impact of external temperature on the cable.
(IV) Production Process
The production process of these copper conductor XLPE
Insulated Power cables is relatively complex and requires multiple strict processes to ensure product quality.
The first step is the preparation of the conductor. High - purity copper materials are selected, and the copper materials are drawn into
Copper Wires with the required diameter through a wire drawing process. During the wire drawing process, it is necessary to strictly control the wire drawing speed and the precision of the die to ensure that the diameter of the copper wire is uniform and the surface is smooth. After that, multiple copper wires are twisted together to form a core with the required cross - sectional area. Twisting can improve the
Flexibility and mechanical strength of the core.
The next step is the extrusion of the insulation layer. The prepared
Copper Core wire is passed through an extruder, and a layer of cross - linked polyethylene insulation layer is extruded on its outside. During the extrusion process, it is necessary to accurately control parameters such as extrusion temperature, pressure, and speed. Excessively high temperature will cause the decomposition of XLPE materials and affect the insulation performance; excessively low temperature will make the insulation layer not closely combined with the copper core, which is easy to cause delamination. The extruded
Insulated Core needs to undergo cross - linking treatment, usually by warm water cross - linking or steam cross - linking, so that the polyethylene molecules form a network structure, thereby obtaining excellent performance.
Then comes the cabling process. The 4 insulated cores are twisted together according to a certain twisting direction and pitch to form a 4 -
Core Cable. During the twisting process, it is necessary to ensure that the position of the cores is accurate and the tension is uniform to avoid core loosening and twisting. At the same time, in order to make the cable structure more stable, some filling materials, such as polypropylene rope, may be filled in the gaps of the twisted cores to ensure the roundness of the cable.
After cabling, the sheath is extruded. According to different models, the corresponding sheath materials are selected, and the sheath layer is extruded on the outside of the cabled core through an extruder. The thickness of the sheath layer should be uniform, the surface should be smooth, and it should be closely combined with the inner core to play a protective role. During the extrusion process, relevant parameters also need to be controlled to ensure the quality of the sheath.
Finally, there is the finished product inspection link. A comprehensive inspection is carried out on the appearance, size, insulation performance, and conductivity of the cable. For example, the insulation strength of the insulation layer is tested through a voltage withstand test, and the conductivity of the conductor is tested through a resistance test. Only cables that meet the relevant standards in all indicators can leave the factory as qualified products.
II. General Product Information
(I) Packaging
Reasonable packaging is crucial to ensure that cables are not damaged during transportation and storage.
These cables are usually packaged with cable reels, and there are two types of cable reels: wooden and steel. For cables with relatively small cross - sections such as 4×10mm² and 4×16mm², due to their relatively light weight, wooden cable reels can be used. Wooden cable reels have low cost and light weight, and are more convenient to carry. However, the load - bearing capacity and strength of wooden cable reels are relatively weak, so they are not suitable for long - term or long - distance transportation.
Cables with a 4×25mm² cross - section are relatively large and heavy, and steel cable reels are generally used. Steel cable reels have high strength and load - bearing capacity, can bear the weight of heavier cables, are not easy to be damaged during transportation, and can better protect the cables. However, steel cable reels have high cost and heavy weight, so the transportation cost will increase relatively.
When packaging, the cable is neatly wound on the cable reel. Appropriate tension should be maintained during the winding process to avoid cable loosening. After winding, the outer layer of the cable is wrapped with a layer of plastic film, which can play a role in moisture proofing and dust proofing, preventing the cable surface from being polluted and corroded. At the same time, the model, specification, length, production date, manufacturer, and other information of the cable will be clearly marked on the cable reel to facilitate users' identification and acceptance.
For short - length cables, they may also be packaged in coils, wrapped with plastic film and then put into cartons. This packaging method is more convenient for small - batch transportation and storage.
(II) Transportation
Many aspects need to be paid attention to in cable transportation to ensure the safety of cables during transportation.
In the loading link, appropriate hoisting equipment, such as cranes and forklifts, should be used to smoothly hoist the cable reels to the transport vehicle. When hoisting, special hoisting tools should be selected to avoid damaging the cable reels and cables. For steel cable reels, attention should be paid to the selection of hoisting points to prevent deformation of the cable reels; for wooden cable reels, avoid excessive force during hoisting to cause the cable reels to break.
During the loading process, the placement position of the cable reels should be reasonably arranged to avoid collision and extrusion between the cable reels. Buffer materials such as rubber pads and foam boards can be placed between the cable reels to reduce damage caused by collision. At the same time, the cable reels should be fixed firmly, and steel wire ropes and fastening belts should be used to fix them on the transport vehicle to prevent the cable reels from rolling and shifting due to vehicle bumps and turns during transportation.
During transportation, appropriate transport vehicles should be selected according to the characteristics of the cables and the transportation distance. For long - distance transportation, large trucks or semi - trailers are preferred to ensure that there is enough space to place the cable reels and that the vehicle runs smoothly. During transportation, violent operations such as sudden braking and sharp turns should be avoided to reduce the impact on the cables.
Attention should also be paid to the impact of the transportation environment. When transporting in rainy and snowy days, the cables should be covered with rainproof cloth and other tools to prevent rainwater and snowwater from entering the interior of the cables and affecting the insulation performance of the cables. In high temperatures in summer, avoid long - term exposure of cables to sunlight to prevent aging of the sheath material. In low temperatures in winter, for some brittle sheath materials, attention should be paid to keeping warm to avoid sheath cracking due to low temperatures.
Transport personnel should be familiar with the transport route and avoid roads with poor road conditions and severe bumps. At the same time, the fixing of the cable reels and the packaging of the cables should be checked regularly, and problems should be handled in time if found.
(III) Delivery
The delivery link is an important link connecting manufacturers and customers and requires rigorous operation.
After receiving the customer's order, the staff should check the order information in a timely manner, including the model, specification, quantity, delivery address of the cable, etc., to ensure that the information is accurate. Then, the corresponding cables are retrieved from the warehouse, and the cables are re - inspected to check whether the packaging is intact, the logo is clear, and there is any damage.
After passing the inspection, arrange appropriate transportation methods and transportation time. According to the customer's requirements and delivery deadlines, choose transportation methods such as express delivery and logistics 专线. If the customer has urgent needs, priority should be given to arranging delivery to ensure delivery within the specified time.
Before delivery, relevant information about the cable, such as model, specification, quantity, transport vehicle information, and estimated arrival time, should be promptly informed to the customer so that the customer can prepare for receipt. At the same time, relevant logistics procedures, such as filling in the waybill and issuing invoices, should be completed, and these documents should be sent with the goods or mailed to the customer as required by the customer.
For orders with large quantities, loading supervision may be required to ensure that the loading of cables meets the requirements and avoid problems during transportation. After delivery, the delivery records should be sorted and archived for subsequent inquiry.
(IV) Samples
In order for customers to intuitively understand the quality and performance of cables before bulk purchase, it is very necessary to provide sample services.
Customers can put forward sample requirements to the manufacturer and specify the model, specification, and other information of the required samples. After receiving the sample requirements, the manufacturer will prepare the corresponding samples within the specified time. The length of the sample is generally 1 - 2 meters, which can meet the customer's inspection of the appearance, structure, and material of the cable.
When preparing samples, it is necessary to ensure that the quality of the samples is consistent with that of mass - produced products. The samples are simply packaged, such as wrapped with plastic film, and the model, specification, production batch, and other information of the samples are marked on the package. At the same time, relevant test reports of the samples, such as insulation performance test reports and conductivity test reports, can be attached to allow customers to have a more comprehensive understanding of the performance of the samples.
Samples are usually sent to customers by express. The manufacturer will choose a reputable express company with fast transportation speed and promptly inform the customer of the express waybill number to facilitate the customer to query the logistics information of the samples. After the samples are sent, the logistics status should be tracked in a timely manner to ensure that the samples can be successfully delivered to the customer.
After the customer receives the samples, the manufacturer can take the initiative to communicate with the customer to understand the customer's feedback on the samples. If the customer has questions about the samples or puts forward improvement suggestions, they should be replied to and handled in a timely manner.
(V) After - sales Service
Perfect after - sales service can provide protection for customers and enhance their purchase confidence.
During the installation of the cable, if the customer encounters technical problems, such as uncertain installation methods and unclear laying requirements, they can contact the after - sales service personnel of the manufacturer by phone, email, online customer service, etc. After - sales service personnel should respond in a timely manner and provide customers with professional technical guidance, such as providing installation manuals and video tutorials, to help customers successfully complete the installation.
If the cable has quality problems during use, the customer can feedback to the manufacturer. The manufacturer should arrange professional personnel to investigate in a timely manner to determine the cause of the problem. If the failure is caused by the product's own quality problems and is within the warranty period, the manufacturer should provide repair, replacement, and other services for the customer in accordance with relevant regulations.
The warranty period is usually determined according to the type of cable and the use scenario, generally 1 - 5 years. During the warranty period, the manufacturer will conduct regular return visits to customers to understand the use of cables and collect customers' opinions and suggestions to continuously improve product quality and service levels.
For cables that exceed the warranty period, the manufacturer can also provide maintenance services, but may charge a certain maintenance fee. At the same time, the manufacturer can also provide customers with cable maintenance suggestions to extend the service life of the cable.
In addition, the manufacturer can also establish customer files, record customer purchase information, use status, feedback opinions, etc., to provide a basis for subsequent services and product improvements. Through high - quality after - sales service, customer satisfaction and loyalty are improved.
