The XLPE Power Cable (4-core, cross-sectional area 50/70/95mm², Copper Conductor, PVC Sheath, 0.6/1kv (400V)) has precise and comprehensive specifications and parameters, which can accurately meet the diverse needs of industrial power distribution scenarios.

The rated voltage of this cable is 0.6/1kv (400V), which fully complies with the standards of industrial power distribution systems and can stably transmit electricity in industrial environments. In industrial production, the working voltage of most equipment is within this range. The rated voltage of 0.6/1kv (400V) not only meets the power needs of various equipment but also leaves a certain safety margin to cope with voltage fluctuations and other situations, ensuring the stability and safety of power transmission. It can be reliably adapted to both the power supply of small production lines and the power distribution of large industrial facilities.

In terms of the number of cores and cross-sectional area, the cable adopts a 4-core design, which makes it very suitable for three-phase four-wire industrial power distribution systems. The 4 Cores correspond to the three phase lines and one neutral line of the three-phase power supply respectively, and can transmit the three-phase power supply and neutral line at the same time, meeting the demand of industrial equipment for multi-phase power and ensuring the normal operation of the equipment. The cross-sectional area provides three options: 50mm², 70mm², and 95mm², and different cross-sectional areas correspond to different current-carrying capacities. The 50mm² cable has a safe current-carrying capacity of about 130A - 150A when laid in the air, which is suitable for power transmission of medium-power equipment, such as the power supply of some small production lines, and can provide stable power support for such equipment. The 70mm² Cable has a larger safe current-carrying capacity, about 160A - 180A, which can meet the power demand of larger power equipment, such as medium-sized motors and compressors. These equipment have large power and high requirements for power transmission, and the 70mm² cable can be well adapted. The 95mm² cable has a safe current-carrying capacity of about 200A - 230A, which is suitable for high-power equipment clusters or main power distribution lines of large industrial production lines, ensuring that strong power can be stably transmitted and guaranteeing the continuous progress of large-scale industrial production.

In addition, the conductor of the cable is made of high-purity copper, and its DC resistance has strict regulations. The DC resistance of 50mm² copper conductor is not more than 0.383Ω/km, that of 70mm² is not more than 0.268Ω/km, and that of 95mm² is not more than 0.193Ω/km. The low DC resistance ensures less loss during current transmission and improves power transmission efficiency. At the same time, the insulation thickness of the cable also has clear standards. The insulation thickness of 50mm², 70mm², and 95mm² cables is not less than 1.4mm. Sufficient insulation thickness ensures good insulation performance and further guarantees electrical safety.

XLPE power cable, relying on its unique performance advantages, has a wide range of characteristic uses in the field of industrial power distribution and can meet the power transmission needs in different industrial scenarios.

In industrial plants, this cable is the core of power distribution. For small and medium-sized industrial plants, the internal production equipment is relatively scattered and has moderate power. 50mm² and 70mm² cables can be used for branch power distribution lines in the workshop, distributing power from the main distribution cabinet to various production equipment, such as CNC machine tools and small processing machinery, ensuring that these equipment receive stable power supply and guaranteeing the smooth progress of production. In large industrial plants with dense equipment and large power, 95mm² cables can be used as main power distribution lines, leading from the substation or main distribution cabinet of the plant to provide strong power support for the power system of the entire plant, and then distributing power to equipment in various regions through branch lines.

The production line in the factory workshop is an important application scenario of this cable. In automated production lines, various equipment work together, and the requirements for power stability are extremely high. 50mm² cables can be used for power transmission in small production lines, connecting the control box of the production line with various small equipment, such as conveyors and small mixers. 70mm² cables are suitable for medium-sized production lines, providing power for medium-sized motors, hydraulic equipment, etc. in the production line to ensure the continuous operation of the production line. For large production lines, such as automobile manufacturing production lines and large chemical production lines, 95mm² cables can undertake the task of main power transmission, providing stable power for many high-power equipment in the entire production line and ensuring the efficient operation of the production line.

The power distribution in industrial parks is also inseparable from this XLPE power cable. There are many different types of enterprises and factories in the industrial park, and the power demand is complex and diverse. This cable can be used as the main power distribution line of the industrial park to transmit power from the substation of the park to various factories and enterprises. 50mm² and 70mm² cables can be used for the branch power distribution network in the park, connecting the main line with the distribution cabinets of various enterprises; 95mm² cables are suitable for the main line, ensuring that sufficient power can be provided for the entire park to meet the production power demand of various enterprises in the park.

In industrial automation systems, this cable also plays an important role. Control cabinets, PLC equipment, robots, etc. in industrial automation systems all need stable power supply. 50mm² and 70mm² cables can be used to connect the power module of the automation system with various control equipment to ensure the stable operation of the automation system. At the same time, in the power connection of automated production lines, this cable can reliably complete the power transmission task, providing a guarantee for the precise operation of automated equipment.

In terms of material selection and style design, XLPE power cable fully considers the harsh requirements of the industrial environment, ensuring the high quality and practicality of the product.

The conductor is made of high-purity copper with a purity of more than 99.9%. This high-purity copper has excellent conductivity, which can efficiently transmit current, reduce energy loss during power transmission, and improve power transmission efficiency. Copper also has good ductility and toughness, which is not easy to break during the processing and installation of the cable, ensuring the integrity of the conductor. At the same time, copper has good oxidation resistance, and is not easy to be oxidized and corroded in the industrial environment, prolonging the service life of the conductor and ensuring long-term stable power transmission.

The insulation layer is made of XLPE (cross-linked polyethylene) material. XLPE has excellent insulation performance with a volume resistivity greater than 10¹⁴Ω·cm, which can effectively insulate current, prevent electric leakage accidents, and ensure the safe operation of the industrial power distribution system. Compared with traditional PVC Insulation Materials, XLPE has better high-temperature resistance and can work stably in the temperature range of -40℃ to 90℃, adapting to possible temperature changes in the industrial environment. In addition, XLPE has high mechanical strength, large tensile strength and elongation at break, which can resist the influence of mechanical stress and vibration in the industrial environment, and is not easy to crack or break, prolonging the service life of the cable.

The sheath layer is made of PVC (polyvinyl chloride) material. The PVC sheath has good corrosion resistance, which can resist the erosion of common oil stains, acids, alkalis and other chemical substances in the industrial environment, protecting the conductor and insulation layer inside the cable from damage. Its wear resistance is also very excellent. During the laying and use of the cable, it can withstand friction, dragging and other external forces, reducing the wear of the sheath and ensuring the integrity of the cable. At the same time, the PVC sheath has good moisture resistance, which can prevent moisture in the industrial environment from entering the cable and affecting the insulation performance of the cable. Moreover, the PVC sheath also has certain flame retardant performance, which can delay the spread of fire in case of accidents such as fire, providing additional protection for the safety of industrial production.

In terms of style design, the cable adopts a circular structure with a regular overall appearance. The 4-core conductors are stranded together, wrapped with an XLPE insulation layer on the outer layer, and the outermost layer is a PVC sheath, with a compact structure and reasonable size. The outer diameter of the cable varies according to the cross-sectional area. The outer diameter of 50mm² cable is about 25mm - 28mm, that of 70mm² is about 28mm - 31mm, and that of 95mm² is about 31mm - 34mm. This design enables the cable to adapt to different laying environments during laying, such as underground direct burial and pipe laying. The surface of the cable is smooth, which is convenient for passing through pipes during laying and reduces resistance. At the same time, the color of the cable is usually black, which is not only dirt-resistant but also can absorb heat, reducing the impact of external temperature on the cable to a certain extent.

The production process of XLPE power cable is exquisite, and every link is strictly controlled to ensure that the product quality meets the high standards of industrial power distribution.

In the production process of the conductor, first of all, the copper raw materials are strictly screened and purified to remove impurities, ensuring that the purity of copper reaches more than 99.9%. Then, the pure copper is made into copper rods through a continuous casting process, and then drawn into Copper Wires with specified diameters through a wire drawing machine. During the wire drawing process, it is necessary to accurately control the wire drawing speed, mold size and cooling system to ensure that the diameter of the copper wire is uniform, the surface is smooth, and there are no cracks, scratches and other defects. Next, multiple copper wires are stranded according to certain stranding rules to form a conductor. During the stranding process, it is necessary to control the stranding pitch and tension to ensure that the conductor structure is tight and round, improving the conductivity and mechanical strength of the conductor. After stranding, the conductor is annealed to eliminate the internal stress generated during wire drawing and stranding, further improving the Flexibility and conductivity of the conductor.

The insulation layer is made by extrusion cross-linking process. First, XLPE materials and cross-linking agents and other auxiliary materials are mixed uniformly in a certain proportion, and then the mixture is heated and melted by an extruder, then uniformly extruded and wrapped around the outer layer of the conductor to form an insulation layer. During the extrusion process, it is necessary to accurately control the temperature, pressure and speed of the extruder to ensure that the thickness of the insulation layer is uniform, the deviation does not exceed the specified range, and it is closely combined with the conductor without defects such as bubbles and impurities. After extrusion, the cable is cross-linked, usually by warm water cross-linking or steam cross-linking, so that the XLPE molecules form a three-dimensional network structure, thereby improving the high-temperature resistance, mechanical strength and insulation performance of the insulation layer. After cross-linking, the cable is cooled to solidify the insulation layer.

The sheath layer is also made by extrusion molding process. PVC materials are mixed with stabilizers, plasticizers and other auxiliary materials uniformly and heated to melt, then extruded by an extruder and wrapped around the outer layer of the insulation layer to form a sheath layer. During the extrusion process, it is necessary to control the extrusion parameters to ensure that the thickness of the sheath layer is uniform, the surface is smooth, and it is closely combined with the insulation layer without defects. At the same time, the sheath layer must have a certain thickness to provide sufficient protection.

During the entire production process, multiple quality inspection procedures are required. In the conductor production stage, the diameter, resistivity, tensile strength and other indicators of the copper wire are tested, as well as the outer diameter and roundness of the Stranded Conductor. After the insulation layer is made, the thickness, insulation resistance, voltage resistance performance, cross-linking degree, etc. of the insulation layer are tested. After the sheath layer is made, the thickness, outer diameter, tensile strength, elongation at break, etc. of the sheath layer are tested. The finished cable also needs to undergo overall performance tests, such as partial discharge test, aging resistance test, bending test, etc. Only products that pass all tests can enter the subsequent packaging link. In addition, strict environmental protection requirements are observed in the production process, and advanced production equipment and processes are adopted to reduce the emission of waste gas, waste water and waste residue, ensuring that the production process meets environmental protection standards.

The packaging design of XLPE power cable fully considers the protection, storage and transportation needs of the product, ensuring that the cable is in good condition when it reaches the user.

The cable is usually packaged in a reel, using high-strength wooden or steel cable reels. The diameter of the cable reel depends on the cross-sectional area and length of the cable. Cables of 50mm² and 70mm² generally use cable reels with a diameter of 800mm - 1200mm, while cables of 95mm² mostly use cable reels with a diameter of 1000mm - 1500mm. The structure of the cable reel is firm, which can bear the weight of the cable and the external impact during transportation, preventing the cable from being deformed or damaged during transportation and storage. The two sides of the cable reel are provided with baffles, which are moderately high, can effectively prevent the cable from falling off the reel, and facilitate the handling and stacking of the cable.

During the cable 装盘 process, the cable will be neatly wound on the cable reel, and the tension is controlled during the winding process to avoid excessive stretching or squeezing of the cable. After winding, a layer of moisture-proof film is wrapped around the outer layer of the cable to prevent the cable from getting damp during storage and transportation. For cables stored for a long time or transported over long distances, a layer of linen or woven bag is wrapped outside the moisture-proof film to further enhance the protection of the cable and prevent the sheath from being worn.

On the side of the cable reel, relevant product information is clearly marked, including product name (XLPE power cable), specifications and parameters (number of cores, cross-sectional area, rated voltage, etc.), length, production date, production batch number, execution standard, manufacturer's name, address, contact information, etc. This information is convenient for users to quickly understand the basic situation of the product and also provides convenience for product traceability. At the same time, some important precautions are also marked, such as "Do not invert", "Handle with care", "Moisture-proof and sun-proof", etc., to remind users to pay attention to protecting the product during handling and storage.

For exported or long-distance transported cables, container transportation is also used. The cable reels with cables are neatly arranged in the container, and the cable reels are firmly fixed with steel wire ropes or fastening belts to prevent shaking and collision during transportation. The container has good sealing and moisture resistance, which can provide better protection for the cable and avoid being affected by the external environment.

The transportation of XLPE power cable strictly follows logistics norms and relevant standards to ensure that the products can be delivered to the destination safely and timely.

In terms of transportation methods, various methods such as road transportation, railway transportation, and waterway transportation can be adopted according to the transportation distance, transportation volume and customer needs. For short-distance transportation and small batches of goods, road transportation is a more commonly used method, which has the characteristics of high flexibility and strong timeliness. The transport vehicles are large trucks, which are equipped with special fixing devices to firmly fix the cable reels in the carriage to prevent rolling and collision during transportation. At the same time, the vehicles are also equipped with rainproof and sunproof awnings to avoid the cable being affected by weather factors.

For long-distance transportation and large quantities of goods, railway transportation and waterway transportation are more economical. Railway transportation uses special freight trains, placing the cable reels on the flat cars of railway freight cars and fixing them with iron chains to ensure the stability of the transportation process. Waterway transportation uses freight ships to load cable reels into containers or directly place them in the cabin, with good fixing and protective measures to adapt to long-term water transportation.

During transportation, the cable needs to be properly protected. No matter which transportation method is adopted, it is necessary to ensure that the packaging of the cable reel is intact, and the cable is not damaged by extrusion, collision, rain, sun exposure, etc. During transportation, avoid inverting the cable reel or tilting it at an excessive angle to prevent the cable from falling off the reel. At the same time, attention should be paid to the environmental temperature during transportation to avoid the cable being stored in extreme high or low temperature environments for a long time, which may affect its performance.

The goods will also be tracked and monitored throughout the transportation process. Through the logistics information system, real-time grasp of the transportation status of the goods, including transportation location, transportation speed, estimated arrival time and other information. If transportation is delayed due to special circumstances such as traffic jams and bad weather, customers will be informed in a timely manner, the situation will be explained and corresponding remedial measures will be taken to ensure that customers can timely understand the dynamics of the goods.
