This specification enables it to have strong power transmission capacity, meeting the power demand of high-power equipment in industrial power distribution. The conductor is stranded by 37 strands of high-purity electrolytic Copper Wires with a single wire diameter of about 2.6mm. The multi-strand stranded design not only increases the Flexibility of the conductor but also improves its overall mechanical strength and heat dissipation performance.

Rated Voltage: The rated voltage is 600V, which conforms to the voltage standard of industrial low-voltage power distribution systems. It is suitable for transmitting electric energy in Power Lines of 600V and below, providing stable power supply for various industrial equipment.

Current-Carrying Capacity: At an ambient temperature of 30℃, the continuous current-carrying capacity can reach 430A, and the short-term overload (1 hour) current-carrying capacity can be increased to 530A. The high current-carrying capacity ensures that the cable can operate stably when dealing with the instantaneous starting current of large transformers, high-voltage motors and other equipment, without overheating due to overload.

Bending Radius: The minimum bending radius is 8 times the outer diameter of the cable. The small bending radius allows the cable to be flexibly laid in complex industrial plant structures, easily coping with narrow spaces and corners that need to be bent, reducing construction difficulty.

Insulation Layer Parameters: The insulation layer is made of PVC material with a temperature resistance level of 90℃, with a uniform thickness of not less than 1.8mm. Sufficient thickness ensures good insulation performance, which can effectively block current and prevent faults such as phase-to-phase short circuits. The volume resistivity of the insulation layer is ≥1×10¹⁴Ω·cm, with excellent insulation performance. It passes the 2500V/5min AC voltage withstand test without breakdown, further verifying its reliable insulation effect.

Mechanical Properties: The overall tensile strength of the cable is ≥16MPa, and the elongation at break is ≥120%. Good mechanical properties enable the cable to withstand common mechanical vibrations, tensions and other stresses in industrial environments, making it not easy to be damaged during construction and use, and prolonging the service life of the cable.

Temperature Resistance Range: It can maintain stable performance in temperature cycles from -40℃ to 90℃. This wide temperature resistance range allows the cable to adapt to climate conditions in different regions and seasons, as well as high-temperature environments that may occur in industrial production.

Weather Resistance: It passes the 1000-hour salt spray test without obvious corrosion, having good corrosion resistance. It can be used in coastal industrial areas or high-humidity environments, and will not age and damage quickly due to environmental factors. At the same time, the cable also has anti-ultraviolet performance. After 1000 hours of exposure to sunlight, the aging degree of the insulation layer does not exceed 10%, making it suitable for outdoor distribution bridge installation.

Flame Retardant Performance: The flame retardant performance meets the UL 94 V-2 standard, which can self-extinguish within 30 seconds after the open flame is removed, and the smoke density rating (SDR) is ≤75. Good flame retardant performance can effectively inhibit the spread of fire, reduce smoke generation, and reduce the harm of fire to personnel and equipment in case of fire.

Line Resistance: The line resistance is ≤0.068Ω/km. The low line resistance means less energy loss during power transmission. When running at full load, the power loss per kilometer does not exceed 12kW, improving the efficiency of power transmission and reducing energy waste.

Power Distribution in Large Industrial Plants: In large industrial plants, the cable can be used as the main line from the plant's main distribution room to the workshop distribution cabinet, connecting the low-voltage side of the 10kV/0.4kV transformer with the low-voltage distribution cabinet, and undertaking the power distribution task of the entire workshop. Due to the large number of equipment and high power in the plant, there are high requirements for the stability and capacity of power transmission. The high current-carrying capacity and stable performance of the Thw 500mcm copper cable can meet this demand, ensuring the normal operation of various equipment in the workshop. For example, in automobile manufacturing plants, high-power equipment such as welding robots and stamping equipment require a lot of electricity, and the cable can provide continuous and stable power support for them.

Auxiliary Power Distribution in Power Stations: In addition to the main generator sets, there are many auxiliary equipment in power stations, such as water pumps, fans, control systems, etc., which also need reliable power supply.

During power generation, the stable operation of auxiliary equipment is crucial to the safety and efficiency of the entire power generation system, and the excellent performance of the cable can provide a strong guarantee for it.

Special Lines in Metallurgical Enterprises: Equipment such as electric arc furnaces and rolling mills in metallurgical enterprises are large-capacity and high-power equipment, which will generate large inrush currents during startup and operation. The Thw 500mcm copper cable can withstand these inrush currents and provide special power supply lines for these equipment. For example, electric arc furnaces need strong current to generate high temperature during smelting, and the cable can stably transmit power to ensure the smooth progress of the smelting process.

UPS Systems in Data Centers: Data centers have extremely high requirements for power reliability, and a power outage may cause huge losses. In the UPS system of data centers, the Thw 500mcm copper cable can be used as the transmission line of the backup power supply. When the main power supply fails, it can quickly transmit the power of the backup power supply to various equipment, ensuring seamless switching during power outages and guaranteeing the continuous operation of the data center.

Long-Distance Power Transmission: Due to its large cross-sectional characteristics, the cable is especially suitable for long-distance power transmission, with a single section laying length of up to 500 meters. In some large industrial parks or factory areas, equipment is relatively scattered, requiring long-distance power transmission. The cable can effectively reduce line loss and ensure the efficiency and stability of power transmission.

Conductor Material: The conductor is made of high-purity electrolytic copper with a purity of ≥99.95%. High-purity copper has excellent conductivity, with a conductivity of 101% IACS, which can reduce energy loss during current transmission and improve power transmission efficiency. At the same time, electrolytic copper has good ductility and toughness, which is convenient for stranding processing, ensuring the quality and performance stability of the conductor.

Insulation Layer Material: The insulation layer is made of specially formulated and improved PVC material, which has excellent oil resistance and chemical stability. PVC material has a relatively low cost and good insulation performance, which can effectively block current and prevent accidents such as electric leakage. The temperature resistance level reaches 90℃, which can maintain stable insulation performance in higher temperature environments.

Appearance Style: The surface of the insulation layer is matte treated. This treatment not only makes the cable look more beautiful but also reduces scratch damage during laying, protecting the insulation layer. Clear specification marks (500mcm, 600V, Thw type) and meter marks are printed on the insulation layer, which is convenient for construction personnel to measure the length and confirm the specification during construction, improving construction efficiency and avoiding losses caused by wrong specifications.

Copper Wire Drawing: First, high-purity electrolytic copper ingots are made into copper rods through smelting, casting and other processes, and then the copper rods are drawn into copper wires with a single wire diameter of about 2.6mm through a wire drawing machine. During the wire drawing process, it is necessary to strictly control the drawing speed, temperature and lubrication conditions to ensure that the diameter of the copper wire is uniform, the surface is smooth, and avoid cracks, scratches and other defects. The drawn copper wire also needs to be annealed to eliminate internal stress and improve the flexibility and conductivity of the copper wire.

Conductor Stranding: 37 strands of treated copper wires are stranded according to a specific stranding pitch (strictly controlled within 12-16 times the outer diameter of the conductor). Multi-head synchronous pay-off technology is adopted to ensure that each strand of copper wire is evenly stressed and tightly stranded. A reasonable stranding pitch and uniform stress can ensure the roundness and stability of the conductor, improving the mechanical strength and heat dissipation performance of the conductor.

Insulation Extrusion: The insulation layer adopts a three-layer co-extrusion process, with the inner layer being a semi-conductive shielding layer, the middle layer being an insulation layer, and the outer layer being an insulation shielding layer. This process can make the three layers closely fit without bubbles, greatly improving the reliability of the overall insulation. During the extrusion process, it is necessary to accurately control the extrusion temperature, pressure and speed to ensure that the insulation layer has a uniform thickness, a smooth surface, and is closely combined with the conductor, ensuring a good insulation effect.

Cooling and Solidification: The cable with the extruded insulation layer enters the cooling water tank for cooling and solidification, so that the PVC material is quickly shaped, ensuring the dimensional stability and performance of the insulation layer. During the cooling process, the water temperature should be controlled to avoid cracks in the insulation layer due to too fast cooling speed.

Printing Identification: On the surface of the cooled cable, specification marks, meter marks and other information are clearly printed by a printing machine. The printing should be firm and clear, able to remain un 脱落 and un 模糊 during long-term use, facilitating user identification and use.

Quality Inspection: Strict quality inspection is required in every link of the production process. The diameter, purity, tensile strength of the copper wire are inspected; the resistance and cross-sectional area of the Stranded Conductor are tested; the thickness, voltage withstand performance, temperature resistance performance of the insulation layer are inspected. The finished cable also needs to undergo more than 20 tests such as conductor resistance, insulation resistance, partial discharge (≤10pC), to ensure that each batch of products meets the requirements of international standards such as ASTM B33, UL 44, NFPA 70, with a complete quality traceability report.

Packaging Method: Thw 500mcm Copper Cables are usually packaged in reels. The reel material is high-strength wood or steel, which can bear the weight of the cable and the pressure during transportation and storage. According to the length of the cable, each reel can be wound with a certain length of cable. Generally, the length of each reel of cable is 100 meters, 200 meters or 500 meters to meet the purchasing needs of different customers.

Packaging Materials: In addition to the reel, the surface of the cable will be wrapped with a layer of plastic film, which plays the role of moisture-proof, dust-proof and scratch-proof, protecting the insulation layer of the cable from damage during transportation and storage. For export products or products transported over long distances, wooden or iron packing boxes will be added outside the reel to further enhance the firmness of the packaging and prevent the cable from being damaged by external impact during transportation.

Identification Information: Clear identification information will be printed on the reel and packing box, including product name (Thw 500mcm copper cable), specification parameters (500mcm, 600V, etc.), length, weight, production batch number, production date, execution standard, manufacturer name, address, contact information, etc. This identification information is convenient for customers to identify products, and also conducive to product quality traceability and after-sales service.

Protective Measures: In order to prevent the cable from being damaged by extrusion, distortion, etc. during packaging, baffles will be installed on both sides of the reel. The height of the baffle is slightly higher than the winding height of the cable, which can effectively prevent the cable from slipping off the reel. In addition, during the packaging process, the cable will be fixed to ensure that it is tightly and neatly wound on the reel, avoiding loosening and mutual friction.

Transportation Method: According to the transportation distance and customer needs, different transportation methods can be selected. For domestic short-distance transportation (distance within 500 kilometers), road transportation is usually adopted, using large trucks to transport the cable to the customer's designated location. Road transportation has the characteristics of high flexibility and fast transportation speed, which can meet customer needs in a timely manner. For long-distance transportation (distance more than 500 kilometers), railway transportation or road transportation can be selected. Railway transportation is suitable for transporting large quantities of goods, with relatively low cost and stable transportation process; road transportation can realize door-to-door service, which is more convenient. For export products, sea transportation is generally used, which can transport a large number of goods with low cost but long transportation time.

Loading and Unloading Requirements: When loading and unloading cables, special lifting equipment such as forklifts and cranes must be used. Manual rough loading and unloading is strictly prohibited to avoid damage to cables and packaging. During hoisting, appropriate slings should be used, which should match the center hole of the reel to avoid reel deformation or cable damage due to uneven stress. During loading and unloading, the cable should be kept stable to avoid collision and violent shaking.

Transportation Protection: During transportation, effective protective measures should be taken to prevent the cable from being affected by natural factors such as direct sunlight, rain, snow cover, etc. The carriage of the transport vehicle should be kept clean and dry, and a soft cushion should be paved under the cable to avoid friction damage caused by direct contact between the cable and the carriage. For cables transported over long distances, it is necessary to regularly check the packaging of the cables to ensure that they are intact. In case of bad weather, corresponding protective measures should be taken, such as covering with rainproof cloth.

Transportation Restrictions: During transportation, national and local traffic regulations must be strictly observed, and overloading and over-limiting transportation are not allowed. Cables should be stacked neatly and orderly to avoid mutual extrusion, ensuring transportation safety. At the same time, according to the characteristics of the cable, the transportation route and time should be reasonably arranged to avoid long-term transportation in extreme weather conditions such as high temperature and severe cold.
