The cable has two models: U1000 R2V and U1000 R02V, both with a 4-core structure, which is round overall and has a compact structure. The two specifications of 4*1.5mm² and 4G1.5mm² have little difference in appearance, and the main difference lies in the stranding method and marking method of the cores.

The sheath color of the cable is usually black or gray. These colors are not only dirt-resistant, but also can absorb heat, reducing the impact of direct sunlight on the cable. On the surface of the cable, there are clear marks, including cable model, specification, rated voltage, manufacturer, production date, certification mark and other information. These marks are printed with wear-resistant ink to ensure that they are clearly distinguishable during long-term use and transportation, facilitating users to identify and trace the product.

When packaged in coils, the coil diameter of the cable varies according to specifications. Generally speaking, the length of each coil is 100 meters, 200 meters or 300 meters, which can be customized according to customer needs. This coil diameter design is convenient for storage and transportation, and also convenient for laying at the construction site.

The production process of U1000 R2V, U1000 R02V 4*1.5, 4G1.5 XLPE Insulated Cables is complex and rigorous. Each link from the selection of raw materials to the inspection of finished products is subject to strict quality control to ensure that the performance and quality of the products meet relevant standards and use requirements.

Conductor manufacturing is the first step of production. First, select high-purity copper ingots with a purity of ≥99.9% for smelting. During the smelting process, it is necessary to accurately control the temperature and time to remove impurities and oxygen in the copper to ensure the purity of the copper liquid. The smelted copper liquid is made into copper rods through a continuous casting and rolling process, and the diameter of the copper rods is determined according to the final conductor specification. Then, the copper rod is drawn into Copper Wires of different diameters through a wire drawing machine. During the wire drawing process, it is necessary to control the wire drawing speed, die precision and cooling system to ensure that the diameter of the copper wire is uniform, the surface is smooth, and there are no scratches, burrs and other defects. Next, multiple copper wires are stranded according to a certain stranding pitch and direction to make a single-core conductor. The multi-strand stranding process can improve the flexibility and mechanical strength of the conductor, and at the same time reduce the skin effect and improve the conductivity.

Insulation layer extrusion is one of the key processes. The stranded single-core conductor is fed into the extruder, and at the same time, high-quality XLPE material is added into the hopper of the extruder. The XLPE material is heated, melted and plasticized in the extruder, and then evenly wrapped around the outside of the conductor through an extrusion die to form an insulation layer. During the extrusion process, it is necessary to strictly control the extrusion temperature, extrusion speed and die pressure to ensure that the thickness of the insulation layer is uniform, closely combined with the conductor, and free of bubbles, material shortages, eccentricity and other defects. The extruded Insulated Core needs to be cross-linked, usually by means of warm water cross-linking or steam cross-linking, so that the XLPE molecules form a three-dimensional network structure, thereby improving its mechanical properties, temperature resistance and electrical properties. The cross-linked insulated core should be cooled by a cooling system to set.

The cabling process is to strand 4 insulated cores according to a certain stranding method and pitch to form a 4-Core Cable. For the 4G1.5mm² cable, special attention should be paid to the arrangement of cores and stranding tension during the stranding process to ensure that the stranding method meets the specification requirements. During the cabling process, in order to ensure the roundness and stability of the cable core, some inert materials, such as polypropylene rope, will be filled in the middle of the cable core. At the same time, it is necessary to ensure that the positions of each core are uniform and the stranding is tight, so as to avoid loosening during subsequent processing and use.

Sheath extrusion is carried out after cabling. The cabled core is fed into the sheath extruder, and weather-resistant PVC material is added into the extruder hopper. The material is heated and melted in the extruder, and then evenly wrapped around the outside of the cable core through an extrusion die to form a sheath layer. During the extrusion process, various parameters should be controlled to ensure that the thickness of the sheath layer is ≥0.8mm, the surface is smooth, closely combined with the cable core, and free of bubbles, cracks and other defects. The extrusion of the sheath layer can not only protect the internal structure, but also enhance the weather resistance and mechanical properties of the cable.

During the production process, multiple quality inspections are required. The diameter, DC resistance, tensile strength of the conductor are tested; the thickness, insulation resistance, voltage resistance performance, temperature resistance performance, flame retardant performance of the insulation layer are tested; the structure and size of the cabled core are checked; the thickness, tensile strength, elongation at break, weather resistance of the sheath layer are tested. The finished cable also needs to undergo overall electrical performance tests, mechanical performance tests and environmental performance tests to ensure that all indicators meet relevant standards and design requirements.

The production environment also has an important impact on product quality. The workshop needs to be kept clean and dry, and the temperature and humidity should be controlled within appropriate ranges to avoid dust, impurities and other factors affecting product performance. Production equipment should be regularly maintained and calibrated to ensure its operating accuracy and stability, and improve production efficiency and the consistency of product quality.

The packaging design of U1000 R2V, U1000 R02V 4*1.5, 4G1.5 XLPE Insulated Cables fully considers the product protection, transportation and storage needs to ensure that the cable is not damaged during the entire circulation process.

The cable is packaged in coils. The length of each coil is usually 100 meters, 200 meters, 300 meters or customized according to customer needs. Packaging materials mainly include wooden cable reels and plastic films. The wooden cable reel is made of high-quality hardwood, which has been dried and anti-corrosive treated, with high strength and stability, and can bear the weight of the cable and the pressure during transportation and storage. Both sides of the cable reel are provided with metal flanges, and the flanges are evenly distributed with a number of holes, which is convenient for handling and loading/unloading with forklifts, cranes and other equipment.

The cable is neatly wound on the wooden cable reel, and appropriate tension is maintained during winding to avoid loosening of the cable or damage caused by mutual friction. The outer layer of the cable is wrapped with a thick layer of plastic film, which has good moisture-proof, dust-proof and anti-corrosion performance, and can effectively isolate the erosion of the cable by external moisture, dust, oil and chemical substances. The plastic film should be closely attached to the surface of the cable and stretched during winding to ensure that there is no gap between it and the cable, forming a sealed protective barrier.

A clear label is fixed on the side or flange of the cable reel. The label details the cable's model, specification, length, rated voltage, manufacturer, production date, production batch number, certification mark and other information. The label is made of waterproof and wear-resistant materials to ensure that the information is clear and legible during transportation and storage, which is convenient for users to identify, count and trace the product.

For exported products or products transported over long distances, the outer part of the wooden cable reel will be reinforced with iron sheets or wooden boxes to enhance the impact resistance and pressure resistance of the packaging and prevent the cable reel from being damaged due to collision and extrusion during transportation. At the same time, the packaging will be printed with internationally accepted warning signs, such as "Do not invert", "Moisture-proof", "

"Handle with care", "Stacking limit", etc., to remind transport and handling personnel to pay attention to operating specifications.

The transportation of U1000 R2V, U1000 R02V 4*1.5, 4G1.5 XLPE Insulated cables needs to select appropriate transportation methods according to factors such as transportation distance, quantity, destination and traffic conditions, and take corresponding protective measures to ensure that the cables are delivered to the destination safely and timely.

Road transportation is a commonly used transportation method, suitable for medium and short-distance transportation. The transport vehicles are usually large trucks or semi-trailers, and the compartments of the vehicles should be flat, clean and free of sharp debris. Before loading, check the integrity of the cable reel and the packaging of the cable to ensure no damage. When loading, use a forklift or crane to smoothly lift the cable reel into the carriage. There should be a certain gap between the cable reels to avoid mutual collision. For multiple cable reels, they should be arranged neatly and firmly fixed on the carriage with steel wire ropes, fastening belts, etc., to prevent movement or dumping during transportation due to vehicle bumps, sudden braking, etc. During transportation, drivers must strictly abide by traffic rules, control the speed, avoid sudden acceleration, sudden braking and sharp turns, and reduce the impact force on the cable. At the same time, attention should be paid to avoiding severe weather such as heavy rain, high temperature, severe cold and strong wind to prevent the cable from being affected by extreme environments.

Railway transportation is suitable for long-distance and large-volume cable transportation, with the advantages of large transportation volume, good stability and relatively low cost. For railway transportation, the cable reel is loaded into the designated position of the railway freight car and fixed firmly with special fixing devices to ensure that it will not move during transportation. For valuable or fragile cables, boxcars can be used for transportation to prevent erosion by natural factors such as wind, sun and rain. The railway department will track and monitor the goods throughout the process to ensure transportation safety.

Water transportation is mainly used for exported products or long-distance cross-water transportation. The cable reel is loaded into the cabin or deck of the cargo ship through the hoisting equipment at the wharf. The cable reels loaded in the cabin should be stacked reasonably to avoid stacking too high to prevent the bottom cable reels from being crushed. The cable reels loaded on the deck need to be fixed more firmly and covered with waterproof cloth to prevent seawater erosion and rain immersion. During transportation, attention should be paid to weather changes and ship navigation conditions, and timely measures should be taken to ensure the safety of the cable.

No matter which transportation method is adopted, appropriate loading and unloading equipment such as forklifts and cranes should be used during loading and unloading. Manual rough loading and unloading is strictly prohibited to avoid damage to the cable reel or scratches and damage to the cable sheath. When loading and unloading, it should be lifted and placed gently to keep the cable reel stable and avoid severe impact. Transport personnel should be familiar with the characteristics and transportation requirements of the cable, and operate in strict accordance with the operating procedures to ensure the safety of the cable during transportation.
