The 3 Core 150mm² Copper Conductor XLPE Power Cable has detailed regulations in various aspects of specification parameters, which collectively determine its excellent performance in power transmission.

In terms of conductor parameters, high-purity electrolytic copper with a purity of over 99.95% is used. This high purity ensures that the conductor has excellent conductive performance. The cross-sectional area of 150mm² is determined through precise calculation, enabling the cable to carry large currents and meet the transmission requirements of three-phase AC power systems. According to authoritative tests, the DC resistance of the conductor is ≤0.124Ω/km, which is much lower than the industry average. This means that during power transmission, energy loss will be greatly reduced, improving the efficiency of power transmission. At the same time, the Flexibility of the conductor also has clear parameter requirements, with a minimum bending radius of 12 times the outer diameter of the cable. This provides convenience for the laying and installation of the cable, allowing smooth construction even in space-constrained environments.

The parameters of the insulation layer are also excellent. The cross-linked polyethylene (XLPE) material used forms a stable three-dimensional network structure after cross-linking treatment, endowing it with excellent electrical properties. The insulation resistance is ≥1000MΩ·km, and this high insulation resistance can effectively prevent current leakage, ensuring the safety of power transmission. In terms of temperature adaptation, the long-term operating temperature of the XLPE insulation layer can reach 90℃, and in short-term overload situations, the temperature can rise to 130℃. Within this temperature range, its insulation performance will not significantly decrease, and it can stably maintain the reliability of power transmission. In addition, the thickness of the insulation layer also has strict standards, with an average thickness not less than the specified value, and the thickness of the thinnest part not less than 90% of the specified value minus 0.1mm, ensuring the uniformity and stability of the insulation effect.

The parameters of the sheath vary depending on the selected material. If a polyvinyl chloride (PVC) sheath is used, its tensile strength is ≥12MPa and elongation at break is ≥150%, which enables the sheath to withstand large mechanical external forces and is not easily damaged when subjected to collisions, friction, etc., effectively protecting the internal structure. At the same time, the corrosion resistance of the PVC Sheath has also been tested. After being immersed in a certain concentration of acid, alkali, and salt solutions for a specified time, the change rates of its tensile strength and elongation at break do not exceed 20%. If a polyethylene (PE) sheath is selected, in addition to having certain mechanical strength, its low-temperature resistance is particularly prominent. It can maintain good flexibility in a low-temperature environment of -40℃ without brittle fracture, making it suitable for use in cold regions.

The overall parameters of the cable also include the rated voltage, usually 0.6/1kV. This voltage level makes it suitable for medium and low-voltage power transmission systems, widely used in industrial, commercial, municipal and other fields. In addition, the outer diameter of the cable is also clearly specified. Different sheath materials will result in slightly different outer diameters, but they are all within the standard range, facilitating planning according to the actual space during laying.

The 3 Core 150mm² Copper Conductor XLPE Power Cable, with its unique performance, has distinctive uses in multiple fields, providing reliable guarantees for power transmission in different scenarios.

In the power distribution system of industrial plants, this cable plays an important role. Industrial plants are usually equipped with a large number of large motors, production lines and other equipment, which have high power and high requirements for power stability. The 3 Core 150mm² specification can meet the large current demand of these equipment, and the design of three cores is compatible with three-phase AC power systems, ensuring the normal operation of the equipment. For example, in the welding production line of an automobile factory, a stable large current supply is needed to ensure welding quality. This cable can continuously and stably transmit power, reducing production failures caused by power fluctuations. At the same time, there may be mechanical vibrations, oil pollution and other situations in the industrial environment, and the PVC sheath of the cable can resist the impact of these adverse factors, prolonging the service life.

In commercial buildings, this cable can be used as a main cable for power distribution trunks and Emergency Power Supply systems. Commercial buildings such as large shopping malls and office buildings have many electrical equipment and large power loads, so the power distribution trunk needs to have large-capacity transmission capacity. The high current-carrying capacity of the 3 Core 150mm² Copper Conductor XLPE Power Cable can meet this demand, ensuring stable power supply in various areas. The emergency power supply system is an important safety guarantee for commercial buildings. In case of sudden power outage, it is necessary to quickly switch to the backup power supply. The reliability of this cable can ensure the smooth transmission of power from the emergency power supply, providing power support for personnel evacuation, operation of fire-fighting facilities, etc. For example, in a high-rise office building, once a fire causes the main power supply to be interrupted, the emergency power supply system supplies power to emergency lighting, elevators and other equipment through this cable, ensuring the safe evacuation of personnel.

In terms of municipal engineering, this cable is suitable for branch lines of urban power grids, street lamp systems, etc. The branch lines of the urban power grid are responsible for distributing power from the main line to various areas, requiring the cable to have good stability and durability. The 3 Core 150mm² Copper Conductor XLPE Power Cable can work stably for a long time in complex outdoor environments, adapting to natural conditions such as temperature changes, wind and rain erosion. The street lamp system is widely distributed and mostly installed outdoors. The weather resistance of this cable enables it to provide continuous power for street lamps under different climatic conditions, ensuring the normal operation of road lighting and the safety of night traffic.

The new energy field is also an important application scenario for this cable. In photovoltaic Power Stations, a large number of electric energy generated by solar panels needs to be collected and transmitted to inverters and other equipment through cables. The high conductivity and weather resistance of the 3 Core 150mm² Copper Conductor XLPE Power Cable can adapt to the outdoor environment of photovoltaic power stations, reducing power transmission losses. The generator sets of wind farms are located in the wild with harsh environmental conditions. This cable can stably transmit power under strong wind, low temperature and other conditions, connecting the generator sets with the collection line and improving the utilization efficiency of wind energy.

In addition, this cable is also widely used in some large public facilities such as stadiums and airport terminals. These places have large power loads and complex electrical equipment, and have extremely high requirements for the safety and reliability of power transmission. The 3 Core 150mm² Copper Conductor XLPE Power Cable can meet these requirements, providing stable power for lighting, air conditioning, security and other systems in the places.

In terms of material selection and style design, the 3 Core 150mm² Copper Conductor XLPE Power Cable fully considers the needs of power transmission and adaptability to different environments, achieving a perfect combination of performance and practicality.

The Conductor Material is high-purity electrolytic copper with a purity of over 99.95%. High-purity copper has excellent conductive performance, which can transmit current quickly and efficiently, reducing energy loss. At the same time, copper has good ductility and toughness. In the processing process, it can be drawn into fine Copper Wires, and then formed into a 150mm² conductor through stranding. The style of multi-strand copper wire stranding not only increases the flexibility of the conductor, making it easier to bend and install during laying, but also improves the mechanical strength of the conductor, enabling it to withstand a certain tensile force and pressure and not easy to break. The surface of the conductor is treated to keep it smooth and clean, reducing the resistance during current transmission.

The insulation layer is made of cross-linked polyethylene (XLPE) material, which is a specially treated polymer material. Through cross-linking reaction, the molecular structure of XLPE material changes from linear to three-dimensional network, endowing it with excellent electrical properties, heat resistance and mechanical properties. Compared with traditional polyethylene, XLPE has a higher temperature resistance level, can maintain stable insulation performance at higher temperatures, and has better anti-aging performance, prolonging the service life of the cable. The insulation layer tightly wraps around the outside of the conductor, forming a uniform and continuous insulation barrier, effectively preventing current leakage.

There are two choices for the sheath material: polyvinyl chloride (PVC) and polyethylene (PE). The PVC sheath has good mechanical strength, wear resistance and corrosion resistance, and the price is relatively economical. Its surface is smooth and the color is uniform, which can effectively resist external mechanical impact, friction and chemical erosion. The PE sheath has better low-temperature resistance and flexibility, is not easy to brittle fracture in low-temperature environments, and is lighter in weight, making installation more convenient. Both sheath materials have certain flame retardant properties, which can delay combustion in case of fire and reduce losses caused by fire.

From the overall style, the cable has a three-core structure. Three 150mm² Insulated Cores are stranded together, and a sheath is wrapped around the outside. This three-core structure design is compatible with three-phase AC power systems, which can transmit A, B, and C three-phase currents at the same time, simplifying line laying and improving the efficiency of power transmission. The appearance color of the cable varies according to the sheath material. The PVC sheath is usually black or gray, and the PE sheath is mostly black. The surface of the cable is printed with clear marks, including model, specification, rated voltage, manufacturer and other information, which is convenient for identification and traceability.

In some special scenarios, the style of the cable can also be customized according to needs. For example, in environments with rodent and ant prevention requirements, special additives can be added to the sheath to make rodent and ant proof cables; in occasions where shielding interference is needed, a shielding layer can be added to improve the anti-interference ability of the cable.

The production process of 3 Core 150mm² Copper Conductor XLPE Power Cable is complex and precise, and each link is strictly controlled to ensure that the product quality meets high standards.

The production process of the conductor includes two main links: wire drawing and stranding. First, high-purity electrolytic copper is made into copper rods. The quality of copper rods directly affects the performance of the conductor, so strict quality inspection is required before production to ensure that its purity, diameter and other indicators meet the requirements. Then, the copper rod is drawn into copper wires of the required diameter through a wire drawing machine. During the wire drawing process, a suitable lubricant is used to reduce the friction between the copper wire and the die, ensuring that the surface of the copper wire is smooth and the size is accurate. The drawn copper wire needs to be annealed. By heating, the internal structure of the copper wire is changed to improve its flexibility and conductivity. Next, multiple copper wires are stranded according to certain rules. During the stranding process, the stranding pitch and tension should be controlled to ensure that the Stranded Conductor has a compact and round structure and uniform conductivity. After stranding, the conductor is inspected for appearance and size, and unqualified products will be rejected.

The extrusion of the insulation layer is one of the key processes, using advanced extrusion equipment to extrude and wrap XLPE material around the conductor. 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, extrusion speed and die size are precisely controlled. Different XLPE materials have their specific melting temperature ranges. Excessively high temperature will cause material decomposition, while excessively low temperature will affect the fluidity of the material, leading to defects in the insulation layer. The extrusion speed is matched with the traction speed to ensure uniform thickness of the insulation layer. The size of the die is precisely calculated to ensure that the inner and outer diameters of the insulation layer meet the standard requirements. The extruded insulated core needs to be cooled through a cooling water tank to make the insulation layer solidify and form quickly. After cooling, the core is inspected for appearance, thickness, insulation resistance and other items to ensure that the insulation layer quality is qualified.

The cabling process is to strand three insulated cores together. Before cabling, each insulated core needs to be inspected to ensure its quality meets the requirements. During the cabling process, the three cores are stranded according to a certain stranding direction and pitch through a cabling machine. At the same time, appropriate fillers, such as polypropylene ropes, are filled in the stranding gap to ensure the roundness and stability of the cable and reduce deformation during subsequent processing and use. After stranding, a layer of non-woven fabric or other materials is wrapped around the cable as an inner liner to enhance the structural strength of the cable.

The extrusion process of the sheath is similar to that of the insulation layer, but the equipment and dies used are different. The extrusion temperature and speed are adjusted according to the selected sheath material (PVC or PE). The sheath material is put into the extruder, heated and melted, and then extruded and wrapped around the cabled core through a die. During the extrusion process, it is necessary to ensure that the sheath layer has uniform thickness, smooth surface, and is closely combined with the inner liner, without bubbles, cracks and other defects. After extrusion, the cable is cooled and dried, and then printed with information such as the model, specification and manufacturer of the cable on the sheath surface.

Finally, the finished cable undergoes a comprehensive quality inspection, including withstand voltage test, insulation resistance test, mechanical performance test, partial discharge test, etc. The withstand voltage test is to apply a certain voltage to the cable within a specified time to observe whether breakdown occurs; the insulation resistance test is used to detect the insulation performance of the cable; the mechanical performance test includes tensile strength, elongation at break and other items to evaluate the mechanical performance of the sheath and insulation layer; the partial discharge test is used to detect whether there is partial discharge inside the cable to ensure the safe operation of the cable. Only cables that pass all inspection items can leave the factory.

The packaging design of 3 Core 150mm² Copper Conductor XLPE Power Cable fully considers the characteristics of the product and the needs of transportation and storage, aiming to maximize the protection of the cable quality during circulation.

The choice of packaging materials depends on the length and weight of the cable, usually using wooden reels or steel reels. The wooden reels are made of high-quality hardwood and dried to avoid deformation due to moisture during use. The structure of the reel is firm, able to bear the weight of the cable and the external impact during transportation. The steel reel has higher strength and durability, suitable for packaging longer or heavier cables. At the same time, its recovery rate is high, which is more environmentally friendly. The diameter of the reel is customized according to the length of the cable, generally 1.2-2.5 meters, to ensure that the cable can be neatly wound on the reel, avoiding looseness and distortion.

When the cable is wound onto the reel, special winding equipment is used to maintain appropriate tension to make the cable arrange closely. During the winding process, a certain gap is left between each circle of cable to prevent damage to the insulation layer and sheath caused by mutual extrusion. For longer cables, they will be fixed at certain intervals during winding to ensure that the cable will not loosen during transportation and storage.

The protective measures for the reel are very thorough. After the cable is wound, a layer of waterproof film is wrapped around the outside of the reel. This film has good waterproof performance, which can prevent rain, moisture, etc. from invading the inside of the cable and protect the insulation performance of the cable. Outside the waterproof film, a layer of canvas is wrapped. The canvas is tough, which can resist external mechanical impact and friction, and also play a dust-proof role. For exported cables, the packaging will also meet international transportation standards, such as using fumigated wooden reels to meet the quarantine requirements of the importing country.

Solid baffles are installed on the sides of the reel, and the height of the baffles is higher than the winding height of the cable to prevent the cable from sliding off from both sides of the reel. The central shaft hole of the reel is equipped with a standard shaft sleeve, which is convenient for using forklifts, cranes and other equipment during transportation and loading and unloading. A label is pasted on the obvious position of the reel, indicating the model, specification, length, rated voltage, production batch number, production date, implementation standard, manufacturer and other information of the cable, which is convenient for customers to identify and check.

For small batches or short-length cables, wooden box packaging can also be used. The wooden box is made of solid wood boards, with moisture-proof paper and soft buffer materials, such as foam plastic, laid inside. After the cable is neatly placed in the wooden box, buffer materials are filled to ensure that the cable will not shake in the wooden box and avoid collision damage during transportation. The outside of the wooden box also indicates relevant product information and transportation marks.

The transportation of 3 Core 150mm² Copper Conductor XLPE Power Cable needs to follow strict regulations and procedures to ensure the safety of the cable during transportation.

The choice of transportation mode depends on the transportation distance, quantity and customer requirements. Short-distance transportation usually adopts road transportation, using special freight vehicles. The carriage of the vehicle should be kept clean and dry, without sharp debris. During transportation, the cable reels are firmly fixed in the carriage, and the reels are bound to the fixed devices of the carriage with steel wire ropes or fastening belts to prevent the reels from rolling and colliding due to bumps, turns, etc. during driving. For multiple reels of cables, a certain gap should be left between the reels to avoid mutual extrusion.

Long-distance transportation can choose railway transportation or waterway transportation. Railway transportation usually uses boxcars or containers, which can provide good protection for cables and avoid being affected by external weather and environment. During loading, the cable reels are also firmly fixed to ensure transportation safety. Waterway transportation is suitable for large quantities and long-distance transportation, and the cables are transported to the

destination by cargo ships. During loading and unloading, professional hoisting equipment is used, and attention is paid to operating specifications to avoid the reels being hit.

During transportation, the cables should be protected from direct sunlight, rain and snow immersion, and extreme temperatures. When transporting in summer, the cables can be shaded to prevent excessive cable temperature; when transporting in cold regions in winter, for cables with PE sheaths, it is necessary to keep warm to avoid the sheath from becoming brittle due to low temperatures. The transport vehicles or ships should be well-ventilated to prevent the cables from getting damp.

Special personnel should be assigned to escort during transportation. The escorts should be familiar with the characteristics of the cables and transportation requirements, and regularly check the fixing of the cables and whether the packaging is intact. If any abnormal situation is found, measures should be taken in time to deal with it. At the same time, transportation records should be made, including transportation time, route, weather conditions, cable status and other information for traceability.

After the cables arrive at the destination, during the unloading process, appropriate hoisting equipment such as forklifts and cranes should be used. When hoisting, attention should be paid to uniform force to avoid the reels from tilting or colliding. It is strictly forbidden to use steel wire ropes to directly bind the cables for hoisting to avoid damaging the sheaths and insulation layers of the cables. After unloading, the cables should be placed on a flat and dry site, avoiding contact with sharp objects and corrosive substances.
