U1000 RO2V cable has clear and detailed settings in terms of specifications and parameters to meet different power transmission needs in power station construction.

The cable has a variety of specifications, including 31.5mm², 32.5mm², 41.5mm², 42.5mm² and other types. Among them, for the 31.5mm² cable, the diameter of each conductor is about 1.38mm, and the outer diameter of the whole cable is about 12mm; for the 32.5mm² cable, the diameter of each conductor is about 1.78mm, and the overall outer diameter is about 14mm; for the 41.5mm² cable, the diameter of each conductor is also about 1.38mm, and the overall outer diameter is about 13mm; for the 42.5mm² cable, the diameter of each conductor is about 1.78mm, and the overall outer diameter is about 15mm.

The rated current of the cable is 16A, which enables it to stably provide power support for control equipment, lighting systems, etc. in the power station. Its rated voltage is 1000V, which belongs to the category of low-Voltage Cables and is fully compatible with the low-voltage distribution system of power stations.

In terms of temperature resistance, the cable performs well and can work normally in an ambient temperature range of -40℃ to 105℃. Whether in cold winter or near high-temperature equipment in the power station, it can maintain stable performance. The insulation resistance is as high as ≥1000MΩ, which ensures the safety of the cable during power transmission and effectively prevents electric leakage.

In addition, the insulation thickness and sheath thickness of cables with different specifications are also different. For cables of 31.5mm² and 41.5mm² specifications, the insulation thickness is about 0.8mm, and the sheath thickness is about 1.0mm; for cables of 32.5mm² and 42.5mm² specifications, the insulation thickness is about 0.9mm, and the sheath thickness is about 1.1mm. The setting of these parameters provides a strong guarantee for the insulation performance and mechanical protection of the cable.

Characteristic Applications

U1000 RO2V cable has unique and extensive applications in power station construction, and cables of different specifications are suitable for different scenarios.

3-Core Cables, such as 31.5mm² and 32.5mm², are mainly applicable to branch lines of three-phase power equipment. In power stations, some small three-phase pumps, fans and other equipment need stable power supply. 3-core cables can reliably transmit power from the distribution system to these equipment to ensure their normal operation. For example, small circulating pumps used in cooling systems in power stations can obtain power through 3*1.5mm² cables, ensuring the continuous operation of the cooling system and maintaining the normal temperature of power station equipment.

4-core cables, including 41.5mm² and 42.5mm², are suitable for distribution circuits that require neutral lines. In scenarios such as control equipment, lighting systems and security equipment in power stations, neutral lines are often needed to balance the circuit and ensure the stable operation of the equipment. The neutral line in the 4-core cable can play such a role, providing stable power for control equipment such as control panels and instrument panels, ensuring that staff can accurately monitor and control the operation status of the power station; at the same time, it can also supply power to the lighting system in the power station, ensuring the brightness of the working area and facilitating the operation of staff; in addition, it can provide power for security cameras, alarm devices and other security equipment to ensure the safety of the power station.

In addition to the above specific equipment and systems, the cable is also suitable for indoor and outdoor laying scenarios in power station construction. Indoors, such as control rooms and distribution rooms, cables can be laid through cable trays and pipes to transmit power for various indoor equipment; outdoors, such as open-air equipment areas and cable trenches of power stations, cables can resist the impact of external environments such as wind, rain and ultraviolet rays and stably transmit power.

Material Styles

The material selection and style design of U1000 RO2V cable fully consider the needs of the power station environment to ensure its stable and reliable performance.

The conductor is made of high-purity copper with a purity of more than 99.9%. High-purity copper has excellent conductivity and low resistance, which can effectively reduce losses during power transmission and improve power transmission efficiency. At the same time, copper material also has good ductility and toughness, which is not easy to break during cable processing and laying, ensuring the integrity and service life of the cable.

The insulation layer is made of XLPE (cross-linked polyethylene) material. After cross-linking treatment, the molecular structure of this material forms a three-dimensional network structure, which has excellent temperature resistance and can maintain a stable insulation effect in the temperature range of -40℃ to 105℃. In addition, XLPE material also has excellent anti-aging performance and chemical corrosion resistance. In the complex environment of power stations with much dust and possible small amounts of chemical substances, it can maintain good insulation performance for a long time, and is not easy to age, crack and other problems, ensuring the safety of power transmission.

The outer layer is covered with a PVC (polyvinyl chloride) sheath. The PVC Sheath has good mechanical strength, which can resist external impact and extrusion, and protect the internal conductors and insulation layers of the cable from damage. At the same time, it also has excellent weather resistance, which can resist ultraviolet radiation and wind and rain erosion, and extend the service life of the cable. In addition, the PVC sheath also has certain flame retardant performance, which can delay the spread of fire in case of fire and other accidents, providing additional protection for the safety of the power station.

In terms of style, the cable has a Multi-Core stranded structure, with 3 or 4 Cores stranded together, and the whole is round. This structure makes the cable have good Flexibility, which is convenient for bending and installation in the complex laying environment of the power station. The color of the cable is usually black, which is not only resistant to dirt, but also can absorb heat, reducing the impact of direct sunlight on the cable and maintaining the stability of the cable performance.

Production Process

The production process of U1000 RO2V cable is strict and precise, and each process is strictly controlled to ensure product quality.

The first step is the production of conductors. High-purity copper materials are made into copper rods through smelting, casting and other processes, and then the copper rods are drawn into Copper Wires of the required diameter through a wire drawing machine. In the wire drawing process, it is necessary to accurately control the drawing speed and die size to ensure that the diameter of the copper wire is uniform and the surface is smooth and free of defects. The drawn copper wire also needs to be annealed. Through the heating and cooling process, the flexibility and conductivity of the copper wire are improved, making it more suitable for subsequent processing.

Next is the extrusion of the insulation layer. The XLPE material is heated to a molten state, and evenly coated on the surface of the Copper Conductor through an extruder to form an insulation layer. In the extrusion process, it is necessary to strictly control the extrusion temperature, pressure and speed to ensure that the insulation layer has uniform thickness, is closely combined with the conductor, and has no bubbles, impurities and other defects. After extrusion, the Insulated Wire core is cross-linked, usually using a dry cross-linking process. In a high-temperature and high-pressure environment, the XLPE molecules undergo a cross-linking reaction to form a stable three-dimensional network structure, thereby improving the temperature resistance, anti-aging and other properties of the insulation layer.

Then there is the cabling process. For Multi-Core Cables, it is necessary to strand multiple insulated wire cores according to a certain stranding direction and pitch to form a cable core. In the stranding process, it is necessary to ensure that the positions of each insulated wire core are uniform and the tension is consistent to avoid uneven stress during the use of the cable. At the same time, fill the gap of the Stranded Cable core with suitable materials, such as polypropylene rope, to ensure the roundness and structural stability of the cable.

Finally, the sheath is extruded. The PVC material is heated and melted, and then evenly coated on the outer layer of the cable core through an extruder to form a PVC sheath. In the extrusion process, it is necessary to control the extrusion parameters to ensure that the sheath has uniform thickness, is closely combined with the cable core, and has a smooth surface. After extrusion, the cable is cooled, printed and other treatments, and the cable's model, specification, rated voltage, manufacturer and other information are printed on the surface of the sheath for easy identification and traceability.

In the entire production process, each process needs to undergo strict quality inspection. For example, 检测 the diameter, resistance and other parameters of the conductor; test the thickness, insulation resistance, voltage withstand performance, etc. of the insulation layer; check the structural size after cabling, the thickness of the sheath, etc. Only cables that pass all inspection items can be judged as qualified products and enter the subsequent packaging and sales links.

From the Perspective of General Product Information

Packaging

The packaging design of U1000 RO2V cable fully considers various factors during transportation and storage to ensure that the cable is in good condition when it reaches the user.

The cable is packaged in a Drum Roll, with the cable wound on a sturdy reel. The reel is usually made of high-strength wood or metal materials, with sufficient load-bearing capacity to bear the weight of the cable and prevent deformation or damage during transportation and storage. The size of the reel is designed according to the specification and length of the cable to ensure that the cable can be neatly wound on it, avoiding distortion and knotting.

After the cable is wound on the reel, a layer of moisture-proof film is covered on its outer layer. The moisture-proof film has good moisture-proof performance, which can effectively block moisture in the air from entering the cable and prevent the cable from being damp and affecting the insulation performance. At the same time, the moisture-proof film can also play a certain dust-proof role, keeping the surface of the cable clean.

To further protect the cable, the outside of the reel will be reinforced. For example, steel strips are used to fix the cable and the reel together to prevent the cable from loosening or falling off the reel during transportation. In addition, the reel will be equipped with devices for easy handling, such as iron frames and lifting rings, which are convenient for mechanical operation during loading, unloading and transportation.

A detailed label will be pasted on the reel, indicating the cable's model, specification, length, rated voltage, production batch number, production date and manufacturer. This information helps users identify and check when receiving and storing cables, ensuring that the received cables meet the order requirements.
