Cable U-1000 Rvfv 3X240mm2 95mm2 U1000 PV-specific copper cable has a clear and photovoltaic-scenario-oriented design in terms of specification parameters. Its rated voltage strictly complies with the U1000 standard, which is formulated for the common power transmission needs of photovoltaic systems. It can accurately match the power transmission requirements of various links in the photovoltaic system, from the PV panels to the inverter and then to the power distribution equipment, ensuring that there will be no problems such as low transmission efficiency or equipment damage due to voltage mismatch during power transmission.

The cable mainly has two specifications: 3×240mm² and 95mm². The 3×240mm² specification means that the cable contains 3 conductors with a cross-sectional area of 240mm². This specification endows it with strong current-carrying capacity, enabling it to meet the needs of high-power power transmission in photovoltaic arrays. In large-scale photovoltaic Power Stations, a large number of PV panels connected in series and parallel to form a photovoltaic array will generate a high current. The 240mm² conductor cross-section can easily carry these currents, ensuring stable power transmission. The 95mm² specification cable is more suitable for branch lines or small and medium-sized photovoltaic systems. In these scenarios, the power transmission volume is relatively small, and the 95mm² conductor cross-section can not only meet the transmission needs but also reduce costs to a certain extent, realizing the rational use of resources.

In terms of the overall size of the cable, cables of different specifications vary in diameter and weight. Due to the larger conductor cross-section, the 3×240mm² cable has a relatively thick overall diameter, with a weight of about XXkg per meter; the 95mm² cable has a thinner diameter, with a weight of about XXkg per meter. This size and weight design not only considers the current-carrying capacity but also takes into account the convenience of laying, and will not increase the construction difficulty due to being too heavy.

In addition, the insulation thickness and sheath thickness of the cable have also been accurately calculated. The insulation layer thickness can ensure sufficient insulation strength under the U1000 voltage, preventing safety hazards such as electric leakage; the sheath thickness can provide good protection for the cable and resist erosion from the external environment. At the same time, the bending radius of the cable is also clearly specified to ensure that the internal structure will not be damaged due to excessive bending during laying.

The conductor is made of high-purity copper with a purity of over 99.99%. High-purity copper has excellent conductivity, which is crucial for photovoltaic systems. The electricity generated by the photovoltaic system needs to be efficiently transmitted to equipment such as inverters. High-purity copper can reduce the resistance during current transmission, reduce power loss, and thus improve the power generation efficiency of the entire photovoltaic system. Compared with low-purity copper, high-purity copper has higher conductivity and is not prone to oxidation, corrosion, and other problems during long-term use, and can maintain stable conductivity.

The insulation layer of the cable is made of a material specially adapted to photovoltaic scenarios. This material has excellent insulation performance, can withstand the voltage under the U1000 standard, and effectively prevent current leakage. At the same time, it also has good weather resistance. PV cables are exposed to the outdoors for a long time and will be affected by various factors such as ultraviolet radiation in sunlight, temperature changes, and humidity. However, this Insulation Material can resist the aging effect of ultraviolet rays and maintain stable performance in the temperature range of -40℃ to 80℃. It will not become brittle and crack due to low temperature, nor will it soften and fail due to high temperature. In addition, the insulation layer also has good chemical corrosion resistance and can resist erosion from air pollutants, rainwater, etc.

The sheath material is also carefully selected to adapt to the outdoor use environment of photovoltaics. It has excellent weather resistance and can further enhance the cable's resistance to harsh outdoor environments. The surface of the sheath is smooth and has a certain hardness, which can resist external mechanical collisions and friction and protect the internal conductors and insulation layer from damage. Moreover, the sheath material also has anti-aging and ozone resistance properties. During long-term outdoor use, it will not crack, harden, or show other aging phenomena due to ozone, sunlight, and other factors, extending the service life of the cable.

The cable adopts a circular design, which has many advantages in the laying of photovoltaic systems. The circular structure makes the outer surface of the cable subject to uniform force, and can better adapt to various pipes and trunking during laying, reducing friction with other objects. At the same time, the circular style is also convenient for coiling and storing the cable, which can save space during transportation and storage. In addition, the color of the cable is usually black. Black can absorb heat, reduce the excessive internal temperature of the cable caused by direct sunlight, and also has certain ultraviolet resistance, further improving the outdoor adaptability of the cable.

The conductor adopts a multi-strand stranded structure, and this production process is the key to improving cable performance. Multi-strand stranding is to strand multiple thin Copper Wires together according to specific rules to form a conductor. This process can first enhance the Flexibility of the conductor. Compared with a single thick Copper Conductor, when the multi-strand Stranded Conductor is bent, each strand of copper wire can slide against each other to disperse the bending stress, enabling the cable to be easily bent and laid in the complex angles and narrow spaces where PV panels are installed, adapting to different installation environments.

Secondly, the multi-strand stranded structure can improve the mechanical strength of the conductor. During laying and use, the cable may be subjected to external forces such as stretching and dragging. The multi-strand stranded conductor can bear greater external forces through the interaction between each strand of copper wire, reducing the risk of breakage. During the stranding process, it is necessary to strictly control the stranding pitch. A reasonable stranding pitch can ensure the roundness and structural stability of the conductor and further improve the flexibility and conductivity of the conductor. In the production process, through advanced stranding equipment and strict quality inspection, each conductor is ensured to meet relevant standards.

The insulation layer is produced by an extrusion process. After heating the insulation material to a molten state, the molten material is evenly wrapped around the conductor through an extruder to form a continuous and dense insulation layer. This process can ensure that the thickness of the insulation layer is uniform, avoiding local uneven thickness, thus ensuring the stability of insulation performance. In the extrusion process, it is necessary to accurately control parameters such as extrusion temperature and extrusion speed. Different insulation materials have their specific process requirements. Only when the parameters are set reasonably can the insulation layer be closely combined with the conductor without defects such as bubbles and gaps.

After extrusion, the insulation layer also needs to undergo cooling treatment to make the material solidify and form quickly, ensuring the dimensional stability and mechanical properties of the insulation layer. The temperature control during the cooling process is also very critical. Too fast or too slow cooling speed will affect the quality of the insulation layer.

The sheath is also produced by an extrusion process, with a layer of sheath extruded outside the insulation layer. The sheath extrusion process needs to ensure a tight combination between the sheath and the insulation layer to avoid delamination. During the extrusion process, it is necessary to control the extrusion pressure and speed so that the sheath material can evenly cover the surface of the insulation layer. At the same time, the thickness of the sheath should be uniform to ensure consistent protection effect on the internal structure.

Since the sheath material needs to have good weather resistance and other properties, it is necessary to pretreat the material before extrusion to remove impurities and moisture and ensure the purity and performance stability of the material. After extrusion, the appearance of the sheath is strictly inspected to ensure that the surface is smooth and free of cracks, bubbles, and other defects.

In large-scale photovoltaic power stations, Cable U-1000 Rvfv 3X240mm2 95mm2 U1000 PV-specific copper cable plays an important role. Large-scale photovoltaic power stations have large-scale photovoltaic arrays and need to transmit a large amount of power from PV panels to inverters and power distribution centers. The 3×240mm² specification cable can meet this high-power transmission demand and ensure stable power transmission. At the same time, large-scale photovoltaic power stations are usually built in open outdoor areas, and cables need to withstand the test of various harsh weather. The weather resistance and anti-aging properties of this cable can ensure that it maintains stable performance during long-term use.

Small and medium-sized photovoltaic systems, such as enterprise rooftop photovoltaics and household distributed photovoltaics, have relatively small power transmission volumes, and the 95mm² specification cable can meet their transmission needs. The installation environment of these systems is often complex, and cables may need to be laid in narrow spaces such as rooftops and walls. The flexibility of this cable enables it to easily adapt to these environments and reduce construction difficulty. In addition, small and medium-sized photovoltaic systems are more sensitive to costs, and the 95mm² specification cable can reduce procurement costs while ensuring performance.

In photovoltaic systems, in addition to high-power transmission of main lines, there are many branch lines used to distribute power from the main line to each PV panel group or small electrical equipment. The 95mm² specification cable is very suitable for these branch lines. Its current-carrying capacity can meet the transmission needs of branch lines, and its small diameter makes it more flexible and convenient in the laying of branch lines.

The multi-strand stranded conductor production process not only enhances the flexibility and mechanical strength of the cable but also improves the conductivity of the conductor. Multi-strand stranding increases the surface area of the conductor, which reduces the skin effect to a certain extent, thereby reducing resistance and improving conduction efficiency. The extrusion process of insulation and sheath ensures the uniformity and compactness of the material, enabling the insulation layer and sheath to give full play to their performance and provide reliable protection and insulation for the cable.

Strict production process control is the key to ensuring cable quality. In the conductor stranding process, the precise control of parameters such as stranding pitch and tension ensures the stable quality of each conductor; in the insulation and sheath extrusion process, the monitoring of parameters such as temperature and speed, as well as the inspection of the appearance, size, and performance of finished products, can timely detect and eliminate unqualified products, ensuring that each section of cable leaving the factory meets quality standards.

The optimization of the production process enables the cable to better adapt to the needs of photovoltaic scenarios. For example, the improvement of flexibility enables it to adapt to the complex angles of PV panel installation; the selection and processing technology of weather-resistant materials enable it to be used stably outdoors for a long time. These process advantages make the cable an ideal choice for photovoltaic systems.

To ensure the quality of the cable during transportation and storage, the cable uses professional packaging materials. Cables are usually wound on wooden or metal cable reels. The cable reel has sufficient strength to bear the weight of the cable and prevent deformation or damage during transportation. Wooden cable reels have low cost and certain cushioning performance, suitable for short-distance transportation; metal cable reels have higher strength, suitable for long-distance transportation and long-term storage.

The outside of the cable reel will be wrapped with a moisture-proof and dust-proof plastic film, which can prevent the cable from being polluted by moisture and dust during transportation and storage and protect the insulation layer and sheath of the cable from damage. For small batches of short-length cables, they will be packaged in cardboard boxes, with foam or soft materials filled inside to avoid the cables from shaking and colliding in the box.

Packaging specifications are determined according to the length and specification of the cable. Cables of 3×240mm² specification usually have a length of 50 meters or 100 meters per reel, and cables of 95mm² specification usually have a length of 100 meters or 200 meters per reel. Such packaging specifications not only consider the convenience of transportation but also can meet the needs of different construction scenarios. The packaging will clearly mark the cable's model, specification, length, rated voltage, production date, and other information, facilitating customers' identification and acceptance. At the same time, warning signs such as "Do not press heavily" and "Moisture and sun protection" will be printed on the packaging to remind transportation and storage personnel to pay attention to relevant matters.

According to different transportation distances and order quantities, choose appropriate transportation methods. For short-distance transportation, such as distribution in surrounding cities, road transportation is usually adopted. Road transportation has high flexibility and can directly deliver the cable to the construction site, reducing transit links. For long-distance transportation, such as inter-provincial transportation, railway transportation or waterway transportation will be chosen. These two transportation methods have low costs and are suitable for large quantities of goods transportation. For urgent orders, air transportation can also be used, but the cost is relatively high.

During transportation, the following points need to be noted: First, the cable reel needs to be fixed firmly to prevent rolling and collision during transportation and avoid mechanical damage to the cable. Steel wires, fastening belts, etc. can be used to fix the cable reel on the transport vehicle, and buffer materials can be placed between the cable reels to reduce mutual collision. Secondly, it is necessary to take moisture-proof, sun-proof, and high-temperature prevention measures. If it rains during transportation, the cable should be tightly covered with a raincloth to prevent rainwater from entering the packaging; in hot summer weather, the cable should be avoided from being exposed to the sun for a long time to prevent the sheath from aging due to high temperature; during winter transportation, although the cable is resistant to low temperature, it is also necessary to avoid the cable from being affected by severe temperature changes.

In addition, professional loading and unloading equipment such as forklifts and cranes should be used when loading and unloading cables, and manual rough loading and unloading are strictly prohibited. During the loading and unloading process, handle with care to avoid the cable reel falling or colliding. At the same time, attention should be paid to protecting the cable packaging to avoid damage to the cable caused by packaging damage.

The shipping process mainly includes the following links: order confirmation, goods sorting, quality inspection, packaging reinforcement, logistics contact, goods handover, and information feedback. After receiving the customer's order, first, confirm the order information with the customer, including cable model, specification, quantity, delivery address, delivery time, etc., to ensure that the information is accurate. Then, sort out the corresponding cables from the warehouse according to the order information, and conduct quality inspection on the cables to check whether the appearance, size, packaging, etc. meet the requirements. For orders that require special packaging, carry out packaging reinforcement. After that, contact the cooperative logistics company, arrange transport vehicles, deliver the cables to the logistics company, and go through relevant handover procedures. Finally, feedback the logistics information, such as the logistics company name, waybill number, and estimated arrival time, to the customer, facilitating the customer to track the goods transportation status.

For cables in stock, after the customer confirms the order and pays, the goods will usually be shipped within 1-3 working days.
