As a Copper Core Power Cable suitable for low-voltage scenarios in Power Stations, the U1000 R2V Cable has rich and precise specification parameters, which can meet the power transmission needs in different scenarios.

The rated voltage of this cable is fixed at 0.6/1kV, which enables it to be stably applied in low-voltage distribution systems, providing safe and reliable power support for various equipment. In terms of conductor specifications, it covers various common specifications such as 5×25mm², 5×50mm², 5×70mm², and 5×95mm². Among them, for the 5×25mm² cable, each conductor has a cross-sectional area of 25mm², and the overall current-carrying capacity of the 5 conductors combined can reach 80-100A under specific environments; for the 5×50mm² cable, the cross-sectional area of a single conductor is 50mm², and the overall current-carrying capacity is approximately 120-150A; for the 5×70mm² Cable, the cross-sectional area of a single conductor is 70mm², and the current-carrying capacity is roughly 160-190A; for the 5×95mm² cable, the cross-sectional area of a single conductor is 95mm², and the current-carrying capacity can reach 200-230A. These current-carrying capacity data are obtained under standard ambient temperature (25℃) and specific laying conditions, and the actual use will be affected by factors such as ambient temperature and laying methods.

The DC resistance of the conductor is also one of the important specification parameters. At 20℃, the DC resistance of the 25mm² conductor is not greater than 0.727Ω/km, the 50mm² conductor is not greater than 0.387Ω/km, the 70mm² conductor is not greater than 0.268Ω/km, and the 95mm² conductor is not greater than 0.193Ω/km. The low DC resistance ensures that the energy loss of the cable during current transmission is small, improving the efficiency of power transmission.

The thickness of the insulation layer varies according to the conductor specifications. The insulation layer thickness corresponding to the 25mm² conductor is about 0.8mm, that of the 50mm² is about 1.0mm, that of the 70mm² is about 1.2mm, and that of the 95mm² is about 1.4mm. Sufficient insulation layer thickness can effectively prevent current leakage, ensure the insulation performance of the cable, and avoid the occurrence of faults such as short circuits.

The thickness of the sheath layer also varies with specifications, generally ranging from 1.8-2.2mm. The sheath thickness of the 25mm² cable is about 1.8mm, and as the conductor specification increases, the sheath thickness increases slightly, with the sheath thickness of the 95mm² specification being about 2.2mm. A suitable sheath thickness provides good mechanical protection for the cable, enabling it to resist external wear and extrusion.

In addition, the bending radius of the cable is clearly specified. The static bending radius is not less than 4 times the outer diameter of the cable, and the dynamic bending radius is not less than 10 times the outer diameter of the cable. This parameter ensures that the cable can be properly bent during installation and use without damaging the internal structure. The operating temperature range of the cable is -40℃ to 90℃, within which the cable can maintain stable performance and adapt to different environmental conditions.

With its excellent performance and diverse specifications, the U1000 R2V cable has distinctive applications in many fields.

In the low-voltage system of power stations, this cable is most widely used. In thermal power stations, it is used to connect large equipment such as boilers and steam turbines to low-voltage distribution rooms, distributing and transmitting the electricity generated by generators. Due to the high ambient temperature and certain dust in thermal power stations, the high-temperature resistance and wear resistance of the U1000 R2V cable can well adapt to this environment. In hydropower stations, there are many underwater and humid environments, and the weather resistance and insulation performance of the cable enable it to operate stably for a long time under such conditions, used to connect equipment such as water turbines and generators to ensure the normal output and distribution of electricity. In the low-voltage distribution link of nuclear power stations, the requirements for the safety and reliability of cables are extremely high. The high-quality materials and stable performance of the U1000 R2V cable make it an ideal choice, used to connect various auxiliary equipment to ensure the safe operation of nuclear power stations.

The low-voltage distribution rooms of industrial enterprises are also important application scenarios for this cable. In large factories, such as automobile manufacturing plants and mechanical processing plants, various production equipment in the workshop requires a large amount of power supply. The U1000 R2V cable can safely and efficiently transmit the electricity from the distribution room to various equipment, meeting their different power requirements. The 5×25mm² cable is suitable for small and medium-power equipment such as small machine tools and fans, while the 5×95mm² cable can be used for high-power equipment such as large stamping equipment and furnaces. In chemical enterprises, some areas have a certain chemical corrosion environment, and the corrosion resistance of the cable can resist the erosion of chemical substances, ensuring the continuity of power transmission.

The U1000 R2V cable is also indispensable in the power distribution systems of large buildings. In high-rise buildings, a large number of cables are needed for power transmission from the underground distribution room to the distribution boxes on each floor. The diverse specifications of this cable can meet the needs of different floors and different electrical equipment, such as elevators, central air conditioners, and lighting systems. In commercial complexes, such as shopping malls and office buildings, there are many and scattered electrical equipment, and the cable can accurately distribute electricity to various areas to ensure the normal operation of various equipment.

In data centers, the low-voltage distribution system has strict requirements on the stability and reliability of cables. This cable can provide continuous and stable power for servers, switches, and other equipment, ensuring the normal operation of data centers.

The material selection and style design of the U1000 R2V cable fully consider its use environment and performance requirements, ensuring the high quality and reliability of the cable.

The conductor is made of high-purity electrolytic copper with a purity of more than 99.9%. High-purity copper has excellent conductivity, which can reduce energy loss during current transmission and improve power transmission efficiency. At the same time, copper has good ductility and Flexibility, making the conductor not easy to break during processing and use, ensuring the service life of the cable. In addition, copper has good oxidation resistance, which can maintain stable conductivity during long-term use and is not easily affected by environmental factors.

The insulation layer is made of cross-linked polyethylene (XLPE), which has a series of excellent properties. XLPE has excellent temperature resistance, able to maintain stable insulation performance at a long-term working temperature of 90℃, and not easily damaged even when encountering a high temperature of 250℃ during a short circuit. Compared with traditional polyethylene, XLPE has a more stable molecular structure, higher mechanical strength, and better aging resistance after cross-linking treatment, which can effectively resist the impact of the external environment and prolong the service life of the cable. At the same time, XLPE has high insulation resistance and low dielectric loss, which can reduce energy loss during power transmission and ensure the safety and stability of power transmission.

The sheath layer is made of polyvinyl chloride (PVC) material, which has good mechanical strength, corrosion resistance, and weather resistance. It can effectively protect the internal structure of the cable, resist external wear, extrusion, and collision, and reduce mechanical damage to the cable. PVC material also has certain chemical corrosion resistance, able to be used normally in environments with slight chemical pollution. In addition, PVC has good processing performance, easy to extrude and form, which can ensure the uniformity and smoothness of the sheath layer, improving the overall quality of the cable.

In terms of style, the U1000 R2V cable has a Multi-Core structure, with 5 conductors twisted together, wrapped with an insulation layer and a sheath layer. This twisted structure makes the cable have good flexibility, facilitating bending and laying during installation. The color design of the cable is also relatively standard, usually with a black sheath layer for easy identification and distinction. Each conductor's insulation layer has a different color, using standard colors such as yellow, green, red, blue, and yellow-green 双色，corresponding to different phase sequences and Ground Wires respectively, which is convenient for installers to perform wiring operations and reduce the risk of misoperation.

In addition, the surface of the cable is usually printed with clear marks, including product model, specification, rated voltage, manufacturer, production date, etc. These marks are not only convenient for users to identify and purchase but also provide a basis for cable quality traceability.

The production process of the U1000 R2V cable is complex and rigorous, and each link is strictly controlled and inspected to ensure that the product quality meets relevant standards and requirements.

The production of the conductor is the first step. First, high-purity electrolytic copper ingots are melted at high temperature and made into copper rods through a continuous casting process. The quality of the copper rod directly affects the performance of the conductor, so it is necessary to strictly control the purity and surface quality of the copper rod. Then, the copper rod is drawn into Copper Wires of the required diameter through multiple drawings by a wire drawing machine. During the wire drawing process, it is necessary to control the drawing speed, die precision, and cooling system to ensure the dimensional accuracy and surface smoothness of the copper wire. Subsequently, multiple copper wires are twisted according to certain twisting rules to form a conductor. During twisting, it is necessary to ensure that the copper wires are closely combined and arranged evenly to improve the conductivity and mechanical strength of the conductor. The twisted conductor needs to be annealed. By heating and heat preservation, the internal stress of the conductor is eliminated, and its flexibility and conductivity are improved.

The extrusion of the insulation layer is one of the key processes. XLPE particles are added to the extruder, heated and melted, and then uniformly extruded and coated on the outer layer of the conductor through a special die to form the insulation layer. During the extrusion process, it is necessary to accurately control the extrusion temperature, pressure, and speed to ensure that the insulation layer has uniform thickness, smooth surface, and is closely attached to the conductor without defects such as bubbles and impurities. After extrusion, the insulation layer is cross-linked, usually using a dry cross-linking process. The conductor with the extruded insulation layer is sent to the cross-linking tube, and under high temperature and high pressure environment, the XLPE molecules undergo a cross-linking reaction to form a three-dimensional network structure, thereby improving the temperature resistance, mechanical strength, and aging resistance of the insulation layer.

The cabling process is to twist 5 conductors wrapped with insulation layers. Twisting needs to be carried out according to a certain pitch and direction to ensure the roundness and stability of the cable. During the twisting process, in order to fill the gaps between the conductors and improve the structural stability of the cable, filling materials, usually polypropylene ropes, are added in the middle. The filling material needs to have certain flexibility and corrosion resistance and will not have an adverse impact on the performance of the cable. After twisting, a layer of polyester tape is wrapped around the outer layer of the cable to play a role in fixing and isolation, preventing the conductor from shifting in subsequent processes.

The extrusion of the sheath layer is the last important process. PVC particles are added to the extruder, heated and melted, and then extruded and coated on the outer layer of the cabled cable through a die to form the sheath layer. During the extrusion process, it is necessary to control the extrusion parameters to ensure that the sheath layer has uniform thickness, smooth surface, and is closely combined with the internal structure. The extrusion of the sheath layer not only ensures its mechanical protection performance but also pays attention to the appearance quality to avoid bubbles, cracks, and other defects. After extrusion, the cable needs to be cooled in a cooling water tank to quickly solidify the sheath layer.

During the entire production process, multiple quality inspections are required. The diameter, resistance, mechanical properties, etc. of the conductor are tested; the thickness, voltage resistance, cross-linking degree, etc. of the insulation layer are tested; the structure and size of the cabled cable are checked; the thickness, mechanical strength, aging resistance, etc. of the sheath layer are inspected. Only cables that pass all inspection items can be packaged and shipped.

The packaging design of the U1000 R2V cable fully considers the protection needs of the product during storage, transportation, and handling, ensuring that the cable can reach the user intact.

For cables with longer lengths, steel cable reels are usually used for packaging. Steel cable reels have the characteristics of high strength and high load-bearing capacity, and can withstand the weight of the cable and external impacts during transportation. The diameter of the cable reel depends on the specification and length of the cable, generally ranging from 1.2-2.0 meters, and the width of the reel is 0.8-1.2 meters. Both sides of the cable reel are equipped with solid baffles with a thickness of not less than 10mm, which can effectively prevent the cable from slipping off the reel during transportation and handling.

Before the cable is wound onto the cable reel, a layer of plastic film is wrapped around the outer layer of the cable. The plastic film has good moisture-proof and dust-proof performance, which can protect the surface of the cable from pollution and moisture erosion, and prevent the cable from being affected by moisture during storage and transportation, which may affect its insulation performance. For cables that need to be stored for a long time or transported in harsh environments, a layer of linen or woven bag is wrapped outside the plastic film to enhance the protective effect and further resist external mechanical damage and ultraviolet radiation.

Detailed product information will be clearly marked on the cable reel, including product model, specification, length, rated voltage, manufacturer, production date, implementation standard, license number, etc. This information is not only convenient for users to check and accept when receiving the goods but also provides a basis for product quality traceability. At the same time, some warning signs will be marked on the cable reel, such as "Do not invert", "Handle with care", "Hoisting position", etc., to remind transportation and handling personnel to pay attention to correct operation methods and avoid cable damage caused by improper operation.

To facilitate the hoisting and handling of the cable, a high-strength steel shaft is installed at the central shaft hole of the cable reel. Both ends of the steel shaft are provided with hoisting rings. The strength of the hoisting rings has been strictly calculated and tested, and can bear the total weight of the cable reel and the cable. After packaging, the cable reel will be firmly fixed on the transport tool with steel wire ropes or steel belts to prevent rolling and displacement during transportation.

For short-length cables or samples, cartons or wooden boxes are usually used for packaging. Foam or soft materials are placed inside the cartons and wooden boxes as buffers to avoid collision and extrusion of the cable during transportation. The packaging is also marked with relevant product information and warning signs to ensure the safe transportation of the cable.

The transportation of the U1000 R2V cable needs to follow strict norms and requirements to ensure the safety and quality of the cable during transportation.

In terms of transportation mode selection, road transportation, railway transportation, or water transportation can be adopted according to factors such as transportation distance, cable quantity, and weight. For short-distance transportation and small quantities of cables, road transportation is a more convenient choice, usually using trucks for transportation. The truck compartment needs to be flat, firm, and equipped with necessary fixing devices, such as steel wire ropes and fasteners, to ensure that the cable reel does not move during transportation. During transportation, routes with good road conditions should be chosen to avoid bumpy and rugged sections, reducing the vibration and impact on the cable.

For long-distance transportation and large quantities of cables, railway transportation and water transportation are more economical and stable. Railway transportation uses special railway freight cars, which can provide large loading space and a stable transportation environment, suitable for long-distance transportation. Water transportation is suitable for cross-regional and transnational transportation, and the cable is transported to the destination by cargo ship. During railway or water transportation, the cable reel needs to be firmly fixed on the transport tool to prevent damage to the cable due to shaking during transportation.

When loading cables, special hoisting equipment such as cranes and forklifts are needed. The hoisting process should be operated smoothly to avoid severe impact and collision on the cable reel. The cable reel should be placed upright on the transport tool and kept balanced. A certain gap should be left between adjacent cable reels to avoid mutual extrusion and friction. For Multi-Layer Cable reels, wooden pads need to be placed between the upper and lower layers to disperse the weight and protect the lower cable reels.

During transportation, attention should be paid to protecting the cable from harsh weather. When transporting in rainy or snowy days, the cable reel should be completely covered with waterproof canvas to prevent rainwater or snow from entering the cable and affecting the insulation performance of the cable. When transporting in high-temperature weather, avoid the cable being exposed to sunlight for a long time. Transportation can be chosen in the morning and evening, or the cable can be shaded to prevent the cable from accelerating aging due to high temperature. When transporting in cold weather, attention should be paid to the anti-freezing of the cable to avoid the cable becoming brittle at low temperatures, which affects its flexibility and mechanical properties.

During transportation, drivers or escorts should regularly check the fixing of the cable and the integrity of the packaging

, and take timely measures to deal with any problems found. For example, if the cable reel is found to be loose, it should be reinforced immediately; if the packaging is found to be damaged, it should be repaired or replaced in a timely manner. After arriving at the destination, special equipment should be used to unload the cable reel smoothly to avoid damage to the cable caused by rough handling.
