Core Cable U1000 RO2V 1*185 copper cable has clear and strict settings in terms of specification parameters, with each parameter carefully considered to ensure its stable and efficient operation in high-voltage power transmission scenarios.
The core specification of this cable is a single-core design, with a conductor cross-sectional area of 185mm². This extra-large cross-sectional area is intended to meet the needs of large current transmission, enabling it to carry a large amount of electricity in high-voltage environments and provide sufficient power support for various large-scale power equipment and projects.
In terms of rated voltage, the cable can withstand a working voltage of 1000V and above, meeting the standards for high-voltage power transmission. It is suitable for high-voltage DC or AC transmission scenarios, capable of maintaining stable performance in high-voltage environments without safety issues such as breakdown.
Conductor DC resistance is an important indicator to measure the conductivity of the cable. At 20℃, the conductor DC resistance of this cable is ≤0.103Ω/km. The extremely low DC resistance means minimal energy loss during current transmission, which can improve the efficiency of power transmission and reduce energy waste.
Insulation resistance is also one of the key parameters. The insulation resistance of this cable is ≥1000MΩ·km. High insulation resistance ensures the insulation performance of the cable, effectively blocking current leakage, preventing faults such as short circuits, and ensuring the safety of power transmission.
In terms of temperature resistance, the insulation layer of the cable can work stably in an environment of -40℃ to 90℃, allowing it to adapt to the climatic conditions of different regions, whether in the cold north or the hot south, and operate normally.
The power frequency withstand voltage test is an important test to verify the insulation strength of the cable. This cable does not break down under 10kV voltage for 5 minutes, fully demonstrating its excellent insulation strength and voltage withstand capacity, enabling it to work reliably in high-voltage environments.
In addition, parameters such as the outer diameter and weight of the cable are also clearly specified. Its outer diameter is reasonably designed to ensure the thickness of the internal conductor and insulation layer while facilitating installation in various laying environments. The weight depends on the length and meets relevant transportation and installation standards.
The 185mm²
Single Core Cable U1000 RO2V 1*185 copper cable, with its unique performance advantages, has characteristic uses in multiple fields and can meet high-voltage power transmission needs in different scenarios.
In the power system, this cable is an ideal choice for incoming and outgoing lines of substations. As a hub of power transmission, substations need to transmit high-voltage power from
Power Stations and then distribute it to various electricity-consuming areas. With its large cross-sectional area and high voltage withstand performance, this cable can efficiently and stably transmit high-voltage power from the main transformer to the distribution device, ensuring the normal operation of the power system. For example, in large substations, a large amount of power needs to be converted and distributed every day, and this cable can withstand such a large power load to ensure the continuity of power transmission.
Large industrial plants have a huge demand for electricity and require stable power supply to maintain production. This cable can be used as the main power transmission line in the plant to provide power support for high-power equipment such as large motors, furnaces, and cranes. In steel mills, steelmaking furnaces need to consume a large amount of electricity to maintain high temperatures, and this cable can stably supply power to them, ensuring the smooth progress of the steelmaking process. At the same time, the environment in industrial plants is often complex, with problems such as mechanical vibration and dust, and the wear-resistant and impact-resistant properties of this cable can adapt to such environments.
The distribution trunk lines of high-rise buildings are also inseparable from this cable. With the development of urban construction, there are more and more high-rise buildings. The elevators, air conditioners, lighting and other equipment in these buildings have a large demand for electricity, and the distribution lines need to bear great pressure. The single-core structure of this cable is convenient for laying in spaces such as shafts and cable trays of high-rise buildings, and can transmit power from the bottom distribution room to each floor of the high-rise, ensuring the normal power supply in the building. In some super high-rise buildings, the transmission distance of the cable is long, and the low-loss characteristic of this cable can reduce the waste of electricity during transmission.
This cable also plays an important role in new energy projects. In photovoltaic power stations, the electricity generated by a large number of solar panels needs to be collected through converging lines and then transmitted to the inverter for conversion. The large current-carrying capacity of this cable can meet the power collection needs of multiple groups of solar panels, ensuring efficient power transmission. In wind farms, the electricity generated by wind turbines also needs to be transmitted to the power grid through cables. This cable can adapt to harsh outdoor environmental conditions and maintain stable performance in wind, sun, and rain.
In addition, this cable is also suitable for power transmission in large infrastructure projects such as
Underground Cable tunnels and bridges. In underground tunnels, cables need to withstand a certain amount of soil pressure and groundwater erosion, and the corrosion resistance of this cable can ensure its long-term stable operation. In bridge construction, the installation space for cables is limited, and the single-core structure of this cable is convenient for installation and arrangement.
(3) Material and Style
The 185mm² single core cable U1000 RO2V 1*185 copper cable fully considers the needs of high-voltage power transmission in material selection and style design to ensure the performance and safety of the product.
In terms of materials, the conductor is made of high-purity electrolytic copper with a purity of more than 99.95%. High-purity copper has excellent conductivity, which can reduce the resistance during current transmission and reduce energy loss. At the same time, electrolytic copper has good ductility and plasticity, and can withstand operations such as bending and stretching during cable production and laying without breaking, ensuring the service life of the cable. In addition, copper has good thermal conductivity, which can timely dissipate the heat generated by the cable during operation, avoiding the impact on the cable's performance due to overheating.
The insulation layer is made of cross-linked polyethylene (XLPE) material. This material has excellent insulation performance, which can effectively block current leakage and ensure the safety of power transmission. XLPE material has excellent temperature resistance and can work stably in the temperature range of -40℃ to 90℃ without degradation of insulation performance due to temperature changes. At the same time, it also has good aging resistance, which can resist the erosion of oxygen, ozone, ultraviolet rays and other factors, extending the service life of the cable. Compared with traditional polyethylene materials, XLPE materials have significantly improved mechanical strength and chemical corrosion resistance after cross-linking treatment.
The sheath is made of flame-retardant polyvinyl chloride (PVC) material, which is also an important characteristic of the RO2V model. The
PVC Sheath has good mechanical strength, which can protect the internal conductor and insulation layer of the cable from external mechanical damage such as collision and extrusion. It also has excellent corrosion resistance, which can resist the erosion of acids, alkalis, salts and other chemical substances and adapt to different environmental conditions. In addition, the PVC sheath has undergone strict flame-retardant treatment. In case of fire, it can delay the spread of flames, reduce the release of toxic smoke, and gain time for personnel evacuation and fire rescue, improving the safety of the cable in fire situations.
In terms of style design, the cable adopts a single-core structure, which enables the cable to have a lower skin effect in high-voltage transmission, reducing local overheating caused by uneven current distribution. The single-core structure also facilitates the laying and installation of the cable, especially in narrow spaces such as cable trays and pipes, which can save installation space and improve construction efficiency.
The appearance of the cable is black, which is due to the color of the PVC sheath. The black appearance is not only beautiful but also has certain light resistance, which can reduce the impact of direct sunlight on the cable. On the surface of the sheath, there are clear product markings, including model, specification, rated voltage, manufacturer and other information, which is convenient for users to identify and trace the product.
In addition, the structure of the cable is compact, and the materials of each layer are firmly bonded, which can prevent moisture, dust and other impurities from entering the cable and affecting its performance. At the same time, the cable has moderate
Flexibility, which can be bent as needed during laying without excessive bending that would damage the internal structure.
(4) Production Process
The production process of the 185mm² single core cable U1000 RO2V 1*185 copper cable is advanced and rigorous, with each process strictly controlled to ensure product quality.
The first is the manufacturing process of the conductor. High-purity electrolytic copper rods are selected as raw materials, and the copper rods are drawn into thin-diameter
Copper Wires through a wire drawing machine. During the wire drawing process, the drawing speed and tension need to be controlled to ensure that the diameter of the copper wire is uniform and the surface is smooth. The drawn copper wire needs to be annealed. The copper wire is heated to a certain temperature and kept for a period of time, then slowly cooled to eliminate internal stress in the copper wire and improve its flexibility and conductivity. The annealed copper wires are stranded through a bunching machine to form a 185mm² single-core conductor. During the stranding process, it is necessary to ensure that the copper wires are arranged neatly and tightly to improve the conductivity and mechanical strength of the conductor.
Next is the extrusion process of the insulation layer. Using cross-linked polyethylene (XLPE) material, it is evenly coated on the surface of the conductor through an extruder to form an insulation layer. Before extrusion, the XLPE material needs to be pretreated to remove moisture and impurities to ensure the quality of the insulation layer. During the extrusion process, the extrusion temperature, pressure and speed must be precisely controlled to ensure that the insulation layer has a uniform thickness, smooth surface, and is tightly bonded to the conductor. After the insulation layer is extruded, cross-linking treatment is required. The cable is placed in a cross-linking tube, and through the action of high temperature and high pressure, the XLPE molecules undergo a cross-linking reaction to form a three-dimensional network structure, thereby improving the temperature resistance, mechanical strength and insulation performance of the insulation layer.
Then comes the extrusion process of the sheath. Flame-retardant polyvinyl chloride (PVC) material is selected and coated on the outside of the insulation layer through an extruder to form a sheath. During the extrusion process, temperature, pressure and speed also need to be well controlled to ensure that the sheath has a uniform thickness, smooth surface, and is tightly bonded to the insulation layer. The thickness of the sheath is designed according to relevant standards to ensure that it can provide effective protection for the cable. After extrusion, the sheath is cooled to make it solidify quickly.
During the production process, multiple quality inspections are required. After the conductor is manufactured, its diameter, DC resistance and other parameters are tested to ensure compliance with standards. After the insulation layer is extruded, its thickness, insulation resistance, voltage withstand performance, etc., are tested. After the sheath is extruded, its thickness, appearance, flame retardant performance, etc., are tested. In addition, the finished cable also needs to undergo overall performance tests such as power frequency withstand voltage test and partial discharge test to ensure that all performance indicators of the cable meet the requirements.
Automated control technology is adopted in the production process to improve production efficiency and the stability of product quality. For example, in processes such as wire drawing and extrusion, computer control systems are used to monitor and adjust various parameters in real time to ensure the stability of the production process. At the same time, the environment of the production workshop is strictly controlled to keep it clean and dry, avoiding the impact of dust and other impurities on product quality.
II. From the Perspective of General Product Information
(1) Packaging
The packaging design of the 185mm² single core cable U1000 RO2V 1*185 copper cable aims to protect the product, facilitate transportation and storage, and adopts a scientific and reasonable packaging method.
Due to the single-core structure and large cross-sectional area of the cable, which is usually long, it is generally packaged using cable reels. There are two types of cable reels: wooden and steel. For short-distance transportation or small-batch shipments, wooden cable reels can be used. Wooden cable reels are relatively light in weight, relatively low in cost, and easy to handle. However, the strength of wooden cable reels is relatively low, making them unsuitable for long-distance transportation or transportation of large quantities of goods.
Steel cable reels have the characteristics of high strength and high load-bearing capacity, and are suitable for long-distance transportation and packaging of large quantities of cables. They can withstand the weight of the cable and various impacts during transportation, effectively protecting the cable from damage. The surface of steel cable reels is usually subjected to anti-corrosion treatment, such as painting and galvanizing, to prevent rust during transportation and storage.
When the cable is wound onto the cable reel, it needs to be done according to a certain tension and order to ensure that the cable is arranged neatly and tightly, avoiding looseness, distortion or mutual friction. During the winding process, the winding speed must be controlled to avoid excessive stretching or extrusion of the cable due to too fast speed. After winding, sealed 封头 are installed at both ends of the cable to prevent moisture, dust and other impurities from entering the cable and affecting its performance.
To further protect the cable, a layer of plastic film is wrapped around the outside of the cable reel. The plastic film has good moisture-proof and dust-proof properties, which can prevent the cable from getting damp and 沾染灰尘 during transportation and storage. For cables that need to be stored for a long time, a layer of linen can be wrapped around the outside of the plastic film. Linen has certain air permeability and wear resistance, which can protect the cable reel from collision and friction, and also prevent the plastic film from aging due to direct sunlight.
Clear markings are set on the cable reel, including product name, model specification, length, weight, manufacturer, production date, execution standard and other information. These markings facilitate users to identify and check when receiving and accepting products, and also facilitate product traceability and management. Lifting holes are also installed on the side of the cable reel to facilitate lifting and handling using cranes and other equipment.
For exported cables, the packaging also needs to meet international transportation standards and the requirements of relevant countries. For example, wooden cable reels need to be fumigated to prevent the spread of diseases and pests. At the same time, the markings on the packaging need to be in English or the language of the destination country to ensure that foreign customers can clearly understand the product information.
(2) Transportation
The transportation process of the 185mm² single core cable U1000 RO2V 1*185 copper cable needs to strictly abide by relevant regulations and requirements to ensure the safety and integrity of the product during transportation.
In terms of transportation mode selection, road transportation, railway transportation, water transportation and other modes can be chosen according to the transportation distance, quantity and customer needs.
Road transportation has the advantages of high flexibility, fast transportation speed, and door-to-door service, and is suitable for short-distance transportation and emergency shipments. For transportation, special freight vehicles such as flatbed trucks and semi-trailers are needed. The load-bearing capacity and size of the vehicle need to match the weight and size of the cable reel. When loading the cable reel, it should be placed stably, and fixed firmly on the vehicle with steel wire ropes, iron chains, etc., to prevent tilting, rolling or collision during transportation. The fixed points should be selected in the solid parts of the cable reel to ensure reliable fixation. At the same time, the driving speed of the vehicle should be moderate, avoiding sudden braking, sharp turns and other operations to reduce the impact on the cable.
Railway transportation is suitable for medium and long-distance transportation of large quantities of goods, with the characteristics of large transportation volume, low cost and good stability. In railway transportation, the cable reel needs to be placed in the designated position of the railway freight car and fixed in accordance with the regulations of the railway department. During transportation, relevant railway transportation regulations must be observed to ensure the safety of the goods.
Water transportation has low cost and large transportation volume, and is suitable for goods transportation in coastal areas or areas with inland waterway shipping conditions. In water transportation, the cable reel needs to be placed in the cabin and properly fixed to prevent the cable reel from moving or colliding due to the shaking of the ship. At the same time, moisture-proof and sun-proof measures should be taken to prevent the cable from being eroded by seawater and rainwater.
During transportation, the following points need to be noted: First, avoid severe vibration and impact on the cable reel to prevent damage to the internal structure of the cable. If the road conditions are poor during transportation, slow down. Second, prevent the cable from being exposed to direct sunlight, rain or soaked in water. Direct sunlight will cause aging of the cable sheath, and rain and water immersion will affect the insulation performance of the cable. Therefore, during transportation, the cable should be covered, such as using a tarpaulin. Third, avoid the cable from contacting with sharp objects to prevent the sheath from being scratched. During loading and unloading, handle with care to avoid collision between the cable reel and other objects. Fourth, abide by traffic rules and relevant regulations of the transportation department during transportation to ensure transportation safety.
For exported cables, special requirements for international transportation also need to be considered. For example, relevant transportation documents such as bills of lading and packing lists need to be processed. At the same time, it is necessary to understand the import policies and regulations of the destination country to ensure that the cables can pass customs smoothly.
Before transportation, the staff will carefully check the packaging and fixing of the cable, and arrange for shipment only after confirmation. During transportation, the goods should be tracked and monitored to keep abreast of the transportation status of the goods. In case of abnormal situations, timely measures should be taken to deal with them, ensuring that the goods can reach the destination safely and on time.
