The 2-Core Cable is mainly used in single-phase circuits, such as lighting circuits; the 3-core cable is suitable for simple connection of three-phase circuits; the 4-core cable adds a neutral wire to the three-phase circuit to meet the needs of more electrical equipment; the 5-core cable integrates a Grounding Wire and can be directly used in scenarios requiring safe grounding without additional wiring.

In terms of electrical performance, the insulation resistance of the PRC insulation layer is ≥100MΩ·km at room temperature, which can effectively block current leakage and ensure electrical safety. At the same time, the cable can withstand a 3kV power frequency withstand voltage test without breakdown, further verifying its excellent insulation performance. In terms of mechanical performance, the tensile strength of the cable is ≥12MPa, and the elongation at break is ≥150%, which can withstand operations such as bending and dragging during laying. The bending radius is not less than 6 times the outer diameter of the cable, ensuring that it will not be damaged due to excessive bending during installation.

With its diverse specifications and excellent performance, the U1000 R02V cable has distinctive applications in many fields.

In the field of civil construction, cables of different cross-sections have their own roles. Small cross-section (1.5-10mm²) 2-core or 3-core cables are often used in lighting circuits in residential buildings, providing stable power for various lamps from living rooms, bedrooms to kitchens and bathrooms. At the same time, they are also suitable for power supply of small household appliances, such as TVs, refrigerators, washing machines, etc., to ensure the normal operation of these appliances. 4-core and 5-core medium cross-section (16-50mm²) cables are used as building power distribution trunks, connecting from the community distribution room to the distribution boxes of each building, and then distributing to each household, ensuring stable power supply for the entire building. In commercial complexes, the cable is used for power supply of lighting systems, air conditioning systems and various commercial equipment. The use of 5-core cables can also provide safe grounding for equipment, ensuring the smooth progress of commercial activities. In addition, the power supply of the fire protection system is also inseparable from it. Its flame retardant performance can delay the spread of fire in case of fire, gaining time for personnel evacuation and fire fighting.

In the industrial field, medium cross-section (16-50mm²) cables are suitable for power connection of small and medium-sized equipment such as machine tools and conveyors. Machine tools have high requirements for power stability during processing. This cable can ensure their normal operation, improving processing accuracy and efficiency. As an important equipment in the production line, the conveyor needs continuous and stable power supply. The U1000 R02V cable can meet this demand, ensuring the continuous operation of the production line. Large cross-section (70-120mm²) cables can be used for power supply of some high-power equipment in factories, such as small compressors and blowers, providing strong support for industrial production. At the same time, in the factory's power distribution system, the cable is used as a branch line to connect various equipment, forming a complete power network.

In municipal engineering, the cable also plays an important role. In the road lighting system, small cross-section (1.5-10mm²) 2-core or 3-core cables are used for power supply of street lamps. Their good weather resistance can adapt to various environmental changes outdoors, ensuring that street lamps illuminate normally at night and guaranteeing road traffic safety. The power supply lines of monitoring equipment are also indispensable. Whether it is road monitoring or community monitoring, the cable can stably provide power for monitoring cameras, video recorders and other equipment, ensuring the normal operation of the monitoring system. In public places such as parks and squares, the cable provides power for landscape lights, audio equipment, etc., enriching people's leisure life. In addition, small water pumps and other equipment in municipal water supply and drainage systems also rely on this cable for power supply, ensuring the normal operation of the city.

In the agricultural field, the U1000 R02V cable also has certain applications. Small agricultural irrigation equipment, such as water pumps, can use medium cross-section (16-50mm²) cables for power supply, ensuring the smooth progress of irrigation work and the growth of crops. Rural household electricity and power supply for small processing plants can also be realized through this cable, providing power support for rural economic development.

The U1000 R02V cable focuses on the combination of performance and practicality in material selection, and its style design can also meet the installation needs of different scenarios.

The conductor is made of high-purity electrolytic copper with a purity of ≥99.9%. This material has excellent electrical conductivity, with a conductivity of 101% IACS, which can effectively reduce energy loss during current transmission and improve power transmission efficiency. High-purity copper also has good ductility and toughness, which is convenient for processing into conductors of various specifications during production and is not easy to break during laying, ensuring the service life of the cable.

The insulation layer is made of PRC (polyvinyl chloride composite) material, which is a new type of material improved on the basis of traditional polyvinyl chloride. It integrates tougheners and weather-resistant additives, not only retaining the characteristics of traditional PVC such as high insulation resistance and excellent voltage resistance, but also significantly improving low-temperature toughness. In the environment of -20℃ to 70℃, the PRC insulation layer can maintain good performance, avoiding the problem that ordinary PVC is easy to embrittle and crack at low temperatures, making it adaptable to a wider temperature range. At the same time, PRC material has certain flame retardant properties, meeting the GB/T 18380 flame retardant standard, which can delay the spread of flames in case of fire, gaining valuable time for emergency treatment.

The outer sheath is also made of PRC material, with uniform thickness and smooth surface. This material has excellent wear resistance, which can resist damage caused by mechanical collisions, ground friction, etc. in construction; has good oil resistance, which can resist oil erosion in industrial environments; and also has certain chemical corrosion resistance, which can cope with the possible humid water vapor and slight chemical erosion in municipal pipelines. The outer sheath is usually black, which can not only absorb heat, reduce the impact of temperature changes on the cable, but also play a certain hidden role in outdoor environments.

In terms of style, in addition to the difference in the number of cores, the cable also has two types: armored and non-armored. Non-Armored Cables are light in weight and flexible, suitable for indoor laying, pipe laying and other environments, and are easy and quick to install. Armored cables have an additional metal armor layer outside the sheath, usually Steel Tape armor, which can significantly improve the cable's resistance to mechanical damage and pressure, and are suitable for scenarios prone to external impact such as underground laying and bridge laying, such as underground parking lots and factory workshop floors. In addition, according to different laying methods, the appearance of the cable is slightly different. For example, the surface of the cable used for open laying is smoother, while the cable used for underground laying has higher requirements on the sheath strength.

The production process of U1000 R02V cable is a collection of a series of precise operations. Every link from raw material processing to finished product inspection is strictly controlled to ensure product quality.

The production of the conductor starts with the smelting of high-purity electrolytic copper. After removing impurities, copper rods are made by continuous casting. The copper rod is drawn into Copper Wires with a diameter meeting the requirements by a wire drawing machine. During the wire drawing process, the wire drawing speed and the precision of the die must be accurately controlled to ensure the uniformity of the copper wire diameter. Subsequently, multiple copper wires are stranded together according to a certain stranding method to form a conductor. The stranding process can improve the Flexibility and filling factor of the conductor. The stranding pitch is strictly controlled according to the cable specifications to ensure the roundness and mechanical properties of the conductor. After stranding, the conductor needs to be annealed, heated to a certain temperature and then slowly cooled to eliminate internal stress and further improve the flexibility and conductivity of the conductor.

The extrusion of the insulation layer is one of the key processes. First, PRC material particles are added to the extruder, heated and melted, and then uniformly coated on the surface of the conductor through a die. During the extrusion process, the extrusion temperature (usually 160-190℃), speed and pressure must be accurately controlled to ensure that the thickness of the insulation layer is uniform, the surface is smooth, and there are no defects such as bubbles and depressions. The thickness of the insulation layer must be strictly in accordance with relevant standards to ensure its insulation performance. Since PRC material is an improved polyvinyl chloride composite, special attention must be paid to the melting state of the material during extrusion to ensure that tougheners, weather-resistant additives, etc. are uniformly mixed with polyvinyl chloride, giving full play to its performance advantages.

For Multi-Core cables, a cabling process is also required. Multiple Insulated Wire cores are stranded together according to a certain stranding method (such as circular stranding). During the stranding process, filling materials must be added to make the cable structure round. The filling material is usually polypropylene rope, etc., which has certain flexibility and insulation performance. After cabling, a layer of tape is wrapped outside, which is made of non-woven fabric or plastic tape, playing a role in fixing the wire core and preventing loosening.

The extrusion of the outer sheath is similar to that of the insulation layer, but the formula of the PRC material used is different to enhance its mechanical properties and weather resistance. The cabled wire core is put into the sheath extruder to extrude the outer sheath, ensuring that the sheath is closely combined with the internal structure without gaps to prevent moisture and impurities from entering. The thickness of the outer sheath depends on the cable specifications, usually between 1.0-2.0mm. During the extrusion process, the temperature, speed and pressure must also be controlled to ensure the quality of the sheath.

During the production process, each process is equipped with strict quality inspection. The diameter, resistance, tensile strength and other parameters of the conductor are sampled and tested; the thickness, appearance, voltage resistance performance of the insulation layer and sheath are comprehensively inspected; the finished cable also needs to undergo overall mechanical performance tests, aging resistance tests, flame retardant tests, etc. For example, a certain number of cables are sampled for bending tests, and after bending, check whether the insulation layer and sheath are cracked; conduct aging resistance tests, place the cable in a specific environment (such as high temperature, high humidity) for a period of time, and then detect whether the performance changes are within the allowable range. Only cables with all indicators qualified can enter the next process and finally be packaged and stored in the warehouse.

The packaging design of U1000 R02V cable fully considers the protection, transportation and storage needs of the product to ensure that the cable is not damaged during circulation.

For small cross-section (1.5-10mm²) cables, reel packaging is usually adopted, and the cable reels are mostly made of plastic. Plastic cable reels are light in weight, easy to carry and store, with diameters generally 300mm, 400mm or 500mm, depending on the length of the cable. The cable is neatly wound on the cable reel, and appropriate tension is maintained during the winding process to avoid loosening or twisting of the cable. Both sides of the cable reel are equipped with plastic baffles, the height of which is higher than the winding height of the cable to prevent the cable from sliding off the side. After winding, the surface of the cable will be wrapped with a layer of plastic film to play a role in moisture-proof and dust-proof. Labels will also be fixed on the cable reel, indicating product name, specification, model, length, weight, production batch number, implementation standard and other information, facilitating identification and management.

Medium cross-section (16-50mm²) and large cross-section (70-120mm²) cables are mostly packaged with wooden cable reels. Wooden cable reels have high strength and can bear the weight of heavier cables, with diameters usually 600mm, 800mm or 1000mm. The winding method of the cable is the same as that of the plastic cable reel, and the outer layer is also wrapped with plastic film. For exported products or cables transported over long distances, the wooden cable reels will also be fumigated to meet the quarantine requirements of international transportation. A forklift hole is reserved at the central axis of the cable reel to facilitate loading, unloading and handling.

In terms of storage, packaged cables should be stored in a dry, ventilated and cool warehouse to avoid direct sunlight, rain and snow. The cable reel should be placed horizontally on a flat ground, and wooden pillows can be placed under it to prevent the ground from getting damp and affecting the cable. Cables of different specifications and models should be stored separately with obvious signs for easy management and access. During storage, the packaging of the cable should be checked regularly for intactness, moisture, damage, etc. For cables stored for a long time, samples should also be taken for performance testing to ensure their quality meets the requirements.

The transportation of U1000 R02V cables needs to strictly follow relevant regulations to ensure that the products are delivered to the destination safely and timely.

The choice of transportation mode depends on the transportation distance, quantity of goods and customer needs. Short-distance transportation (such as in the city or surrounding areas) mostly uses road transportation, and small trucks or vans can be used. The carriage of the transport vehicle should be clean, dry and free of sharp debris to prevent damage to the cable. During transportation, the cable reel should be firmly fixed in the carriage, and steel wire ropes or fastening belts can be used to connect it with the carriage to avoid sliding or tipping due to bumps and turns during driving. For small cross-section cable reels, they can be loaded and unloaded manually; for larger cable reels, equipment such as forklifts must be used for loading and unloading to ensure the safety of the loading and unloading process.

Long-distance transportation can choose railway transportation or logistics dedicated lines. Railway transportation is suitable for large quantities of cable transportation, with the advantages of large transportation volume, low cost and good stability. The cable reel should be placed on the flat car of the railway freight car and fixed firmly with ropes or chains to prevent movement during train operation. At the same time, moisture-proof and sun-proof measures should be taken, and a waterproof cloth can be covered on the cable reel. Logistics dedicated lines provide door-to-door services, which are more convenient for the transportation of a moderate number of cables. Logistics companies will arrange appropriate vehicles according to the goods situation and be responsible for the entire transportation and safety of the goods.

During transportation, the cable should be avoided from severe impact and vibration, and it is strictly forbidden to throw or roll the cable reel. When loading and unloading the cable reel, attention should be paid to maintaining balance to avoid tilting or falling of the cable reel. During transportation, attention should be paid to weather changes. In high-temperature seasons, sunshade measures should be taken to prevent the cable from aging due to high temperature; in cold seasons, although PRC materials have certain low-temperature toughness, there is no need for special heat preservation, but the cable should be avoided from being exposed to extreme low-temperature environments for a long time.

Special personnel should be responsible for escorting during transportation. The escorts should be familiar with the characteristics and transportation requirements of the cables, and regularly check the fixing of the cables and the integrity of the packaging. If any abnormal situation is found, measures should be taken to deal with it in time and report to the relevant departments. After the goods arrive at the destination, the appearance and packaging of the cable should be checked together with the receiver, and the handover can be signed only after confirmation.
