The wire diameter and cross-sectional area of this specification have been scientifically calculated, giving it strong current-carrying capacity. At an ambient temperature of 30°C, the continuous current-carrying capacity can reach about 20A, which can be adapted to various medium-power electrical equipment, such as appliances with a power of around 4kW, ensuring that the wire will not overheat due to overload during the operation of the equipment.
Conductor Structure and Resistance: The conductor is composed of multiple strands of fine copper wires stranded together, usually dozens of copper wires with a diameter of about 0.15-0.2mm woven in a specific stranding manner. This stranded structure has many advantages. It not only improves the Flexibility of the wire, enabling it to be easily bent and laid in complex environments such as narrow spaces and corners, reducing construction difficulty, but also enhances its fatigue resistance. During long-term use, even after multiple bendings, it is not easy to break, thereby extending the service life. At 20°C, the maximum resistance of the conductor does not exceed 5.21Ω/km. The low resistance value ensures efficient current transmission, reduces energy loss during transmission, and also reduces the heat generated due to excessive resistance, improving the safety of the wire in use.
Insulation Layer Parameters: The insulation layer is made of low-smoke PVC material with a thickness of about 0.8-1.0mm. This thickness design not only ensures good electrical insulation performance, which can effectively isolate current and prevent leakage and short-circuit accidents between the wire and other conductors, but also reduces the weight of the wire to a certain extent, facilitating installation and laying. At room temperature, the insulation resistance of the insulation layer is greater than 100MΩ·km. This high-performance index ensures that during long-term use, the insulation layer will not deteriorate due to aging, moisture, etc., and always maintain a good insulation effect. At the same time, low-smoke PVC material has unique characteristics. When burned, it emits less smoke and low toxic gas, meeting environmental protection and safety requirements. Especially in crowded places, it can buy time for personnel evacuation and rescue work in case of fire.
Wire Outer Diameter: The outer diameter of the wire is about 4.5-5.0mm. The appropriate outer diameter size enables it to be compatible with conventional wire tubes and installation spaces. Whether in wall embedding, cable tray laying or surface mounting, it can pass through smoothly, reducing obstacles during installation and improving construction efficiency.
Operating Temperature Range: Its operating temperature range is usually -15°C to 90°C, and it can maintain stable performance in a relatively wide temperature range. In cold winters, even if the ambient temperature is as low as -15°C, the wire will not become brittle due to low temperature and can still maintain good flexibility. In hot summers or environments with high temperatures near equipment, when the temperature reaches 90°C, the insulation layer will not soften or deform, ensuring the normal operation of the wire.
Industrial Control Field:
Signal Transmission Lines for Automation Equipment: In industrial automated production lines, reliable signal transmission is required between various sensors, actuators and controllers. Due to its good flexibility and low resistance, this wire can be used as a signal transmission line to ensure stable signal transmission. At the same time, different colors are convenient for distinguishing different signal loops. For example, red can be used to transmit control signals, and black can be used to transmit feedback signals, reducing the risk of wiring errors and improving the reliability of the automation system.
Control Lines: The connecting lines between components such as relays and contactors in industrial control equipment can use this wire. Its current-carrying capacity can meet the current requirements of the control loop, and the good insulation performance of the low-smoke PVC Insulation layer ensures the safety of the control loop, avoiding faults such as short circuits that affect the normal operation of the equipment.
Commercial Building Field:
Wiring for Lighting Systems: The lighting systems in commercial buildings such as shopping malls, office buildings and hotels are usually complex and require a large number of wires for connection. The current-carrying capacity of this wire is suitable for the power requirements of lighting fixtures. Various colors can be used to distinguish different lighting loops. For example, blue can be used for public area lighting, and white can be used for emergency lighting, facilitating later maintenance and overhaul. At the same time, its low-smoke characteristic can reduce the impact of smoke on personnel evacuation and rescue work in case of fire, improving the fire safety level of commercial buildings.
Wiring for Socket Circuits: Sockets in commercial buildings are densely distributed and connected to various equipment. This wire, as the wiring for socket circuits, can meet the electricity needs of various office equipment and small appliances. Different colors can be used to distinguish live wires, neutral wires and Ground Wires. For example, red as the live wire, black as the neutral wire, and green as the ground wire, ensuring electrical safety.
Residential Decoration Field:
Power Supply Lines for Household Appliances: In residential decoration, power supply lines for household appliances such as refrigerators, washing machines, TVs and air conditioners often use this wire. Its current-carrying capacity can meet the power requirements of these appliances, ensuring their normal operation. A variety of colors are convenient for distinguishing different line functions. For example, red is connected to the live wire, blue to the neutral wire, and yellow-green (green can be used as one of the identifiers of the ground wire here) to the ground wire, improving the safety of residential electricity use and avoiding electric shock accidents caused by wrong line connections.
Indoor Wiring: This wire can also be used for the overall wiring of lighting, sockets and other lines in residences. It has good flexibility and is easy to lay in wire tubes in walls, floors, ceilings and other parts, adapting to the complex wiring environment in residences.
Ship and Rail Transit Field:
Wiring for Internal Electrical Systems: The internal space of ships and rail transit vehicles is limited, and the safety requirements are extremely high. The low-smoke and environmental protection characteristics of this wire make it an ideal choice for wiring of internal electrical systems. In case of emergencies such as fires, it can reduce the generation of smoke and toxic gases, creating favorable conditions for personnel evacuation and emergency treatment. At the same time, its good wear resistance and vibration resistance can adapt to the 颠簸 and vibration environment during ship navigation and rail transit operation, ensuring the stable operation of the electrical system.
Other Fields:
Emergency Power Supply Systems: Emergency power supply systems need to be put into use quickly when the main power supply fails to provide power for important equipment. This wire can be used as the connecting line of the emergency power supply system, and its reliable performance ensures stable power supply in emergency situations, ensuring the normal operation of emergency equipment.
Power Supply for Communication Equipment: Communication equipment in communication base stations and computer rooms needs stable power supply support. This wire can meet the electricity needs of communication equipment, and its low-smoke characteristic also meets the fire safety requirements of places such as computer rooms, reducing fire damage to communication equipment.
Conductor Material: The conductor is made of high-purity electrolytic copper with a purity of more than 99.9%. High-purity electrolytic copper has excellent conductivity, which can efficiently transmit current, reduce energy loss during transmission, and ensure the normal operation of electrical equipment. At the same time, copper has good ductility and toughness, so that fine copper wires are not easy to break during stranding, ensuring the stability of the conductor structure. In addition, copper has relatively stable chemical properties, and is not easy to be oxidized and corroded in normal use environments, which can maintain good conductivity for a long time and extend the service life of the wire. Even in a humid environment, a dense oxide film will form on the copper surface to prevent further corrosion.
Insulation Layer Material: The insulation layer is made of low-smoke PVC material, which has many excellent characteristics. In addition to good electrical insulation performance, it also has excellent wear resistance. During the laying, installation and use of the wire, it can resist friction with pipes, walls, other wires, etc., protecting the internal Copper Conductor from damage. At the same time, low-smoke PVC material has certain acid and alkali corrosion resistance, and can be used in environments with slight chemical pollution, such as workshops and laboratories in some factories, reducing the erosion of chemical substances on the insulation layer. Most importantly, low-smoke PVC produces low smoke concentration when burned, with high light transmittance, which is helpful for personnel evacuation and rescue work in case of fire. Moreover, it releases less toxic gas, which can reduce harm to human body and equipment, in line with modern environmental protection and safety concepts.
Style Design:
Color Options: This wire is available in five colors: red, black, blue, white and green, each with its specific purpose and identification significance. Red is usually used as the live wire, black can be used as the neutral wire or the line of a specific loop, blue is often used as the neutral wire, white can be used for control lines or neutral lines, and green can be used as the ground wire or the identification of specific functional lines. The rich color options facilitate quick and accurate identification of the functions of different lines during circuit installation and maintenance, reducing the risk of wiring errors, and improving construction efficiency and the safety of the electrical system.
Appearance: The wire is cylindrical overall with a compact structure. Due to the adoption of a Stranded Conductor structure, its appearance looks softer and more elastic. The surface of the insulation layer is smooth and flat, without obvious protrusions, depressions or bubbles. This regular appearance allows the wire to pass through the wire tube smoothly during laying, reducing frictional resistance, and is also convenient for cleaning and maintenance.
Identification Information: On the surface of the wire's insulation layer, in accordance with the requirements of relevant industry standards, clear identification information is printed. This information includes the wire's model (600V 12 AWG Thw-Ls), specification, rated voltage, implementation standard, manufacturer's name or trademark, production date, etc. These identifications not only facilitate users to identify and confirm product information when purchasing, but also provide an important basis for the quality traceability and after-sales service of the wire, ensuring product traceability and quality reliability.
Copper Rod Melting and Casting: First, high-purity electrolytic copper raw materials are put into a melting furnace for melting. During the melting process, it is necessary to accurately control the temperature in the furnace, generally around 1083°C, which is the melting point of copper, to ensure that the copper raw materials can be completely melted into a uniform copper liquid. At the same time, it is necessary to remove impurities from the copper liquid, such as oxides and sulfides, by adding refining agents to ensure the purity of the copper liquid. The melted copper liquid is introduced into a continuous casting and rolling machine and cast into a solid copper rod blank. The diameter of the copper rod blank is determined according to the subsequent production needs, generally 8mm or 10mm.
Copper Wire Drawing: The copper rod blank is drawn through a wire drawing machine to draw the thick copper rod into fine copper wires of the required diameter. The wire drawing process is to gradually thin the copper rod through a series of dies with different apertures, and each drawing can reduce the diameter of the copper wire by a certain extent. During the wire drawing process, it is necessary to accurately control the drawing speed, tension and mold temperature. The drawing speed is usually adjusted according to the material of the copper rod and the required diameter of the copper wire, and the tension should be uniform to avoid breaking or deformation of the copper wire during drawing. The temperature of the mold should also be controlled within an appropriate range to prevent the performance of the copper wire from being affected by excessive temperature. The drawn fine copper wire needs to be annealed. By heating and heat preservation, the internal stress of the copper wire is eliminated, and its flexibility and ductility are improved, facilitating the subsequent stranding process.
Conductor Stranding: Multiple strands of annealed fine copper wires are stranded through a stranding machine to form a stranded conductor that meets the 12 AWG specification. During the stranding process, it is necessary to follow a certain stranding pitch and direction. The size of the stranding pitch will affect the flexibility and filling factor of the conductor, and is usually accurately controlled according to the product design requirements. During stranding, it is necessary to ensure that each strand of copper wire is evenly stressed and neatly arranged, avoiding loose strands, broken strands, etc., to ensure the stability of the conductor structure and good conductivity. After stranding, the conductor is subject to appearance inspection and size measurement to ensure that it meets the specification requirements.
Insulation Layer Extrusion (Including Color Formation): The stranded conductor is fed into the head of the extruder, and at the same time, low-smoke PVC Insulation Material (granular) is added to the hopper of the extruder, and corresponding color masterbatches are added according to the required color. Low-smoke PVC particles go through processes such as heating, melting, and plasticizing in the extruder to become a molten PVC melt. Then, the PVC melt is uniformly extruded through the die of the head and wrapped around the outer layer of the conductor to form an insulation layer. During the extrusion process, it is necessary to accurately control parameters such as extrusion temperature, screw speed, and traction speed. The extrusion temperature is generally controlled between 160-190°C to ensure that the low-smoke PVC melt has good fluidity and plasticizing effect. The screw speed and traction speed should be matched to ensure that the thickness of the insulation layer is uniform and has a high concentricity with the conductor, and the thickness is strictly controlled within the range of 0.8-1.0mm. At the same time, it is necessary to ensure that the color is evenly distributed in the insulation layer, with bright color, meeting the design requirements.
Cooling and Solidification: The extruded wire immediately enters a cooling water tank for cooling treatment. The water temperature in the cooling water tank is generally controlled between 20-30°C. Through the action of cold water, the low-smoke PVC insulation layer wrapped around the conductor is quickly cooled and solidified into the required shape. The cooling process adopts a segmented cooling method, first using water at a lower temperature for preliminary cooling, then gradually increasing the water temperature to avoid internal stress or cracks in the insulation layer due to too fast cooling. The cooled wire insulation layer should have a certain hardness and elasticity, feeling smooth and tough to the touch.
Spark Test: To test the electrical insulation performance of the wire's insulation layer, the cooled wire needs to undergo a spark test. The wire is driven by a traction device to pass through a high-voltage electrode, and a high-voltage electric field is generated between the electrode and the wire. If there are defects such as pinholes and cracks in the insulation layer, the high-voltage electricity will break down the defective part and generate sparks. At this time, the equipment will automatically send an alarm signal, and the operator will promptly mark the defective wire for repair or rejection. The spark test can effectively detect tiny defects in the insulation layer, ensuring that the insulation performance of the wire meets relevant standard requirements.
Take-up, Cutting and Packaging: The wires that pass the spark test are pulled to the take-up machine and wound according to the specified length (such as 100 meters, 500 meters, 1000 meters, etc.). During the take-up process, it is necessary to control the take-up tension to make the wire wound neatly and tightly, avoiding looseness, distortion or knotting. For orders requiring specific lengths, after winding, cutting is carried out to ensure that the length of each section of wire meets the requirements. Finally, the wire is packaged, usually with plastic reels or cartons, and the outer layer is wrapped with plastic film to prevent moisture and dust. The package is printed with clear product information and logos, facilitating product storage, transportation and sales.
Packaging Materials:
Plastic Reels: For long-length wires (such as 500 meters and 1000 meters), plastic reels are usually used for packaging. The reels are made of high-strength polypropylene (PP) material, which has good impact resistance and wear resistance, and can effectively protect the wire during transportation and handling. The reel consists of a central cylinder and two side discs. The diameter of the central cylinder is designed according to the wire's outer diameter to ensure that the wire can be tightly wound without looseness. The side discs are provided with reinforcing ribs to enhance the structural strength of the reel, preventing deformation under pressure.
Cartons: Short-length wires (such as 10 meters, 20 meters, 50 meters, and 100 meters) are packaged in cartons. The cartons are made of five-layer corrugated cardboard, which has excellent compressive strength and can withstand the pressure of stacking during storage and transportation. The inner wall of the carton is lined with moisture-proof paper to prevent the wire from being affected by moisture. For wires of 10-50 meters, they are usually coiled into a circular shape and fixed with a paper clip to avoid loosening; for 100-meter wires, they are wound on small plastic spools first and then placed in the carton.
Plastic Film: Regardless of the packaging method, the outer layer of the wire is wrapped with a layer of polyethylene plastic film. The plastic film is transparent, which is convenient for checking the appearance and color of the wire without opening the package. It also has good moisture-proof and dust-proof effects, keeping the wire clean and dry during storage and transportation.
Labels and Stickers: Each package is affixed with a label or sticker containing detailed product information, including product name, model (600V 12 AWG Thw-Ls), color, length, batch number, production date, manufacturer's name, address, and contact information. In addition, there are also identification marks such as "Handle with Care", "Moisture-Proof", and "Stacking Limit" on the package to remind handlers to operate correctly.
Packaging Process:
For Plastic Reel Packaging: The qualified wire after take-up is first wrapped with plastic film, ensuring that the entire reel is completely covered. Then, a label is pasted on the side disc of the reel, and the reel is placed on a pallet for centralized storage. When preparing for shipment, the reels are fixed on the pallet with strapping to prevent them from rolling during transportation.
For Carton Packaging: The coiled or spooled wire is placed in the carton, and buffer materials such as foam pads are filled in the gaps to prevent the wire from shaking and colliding in the carton. After closing the carton, it is sealed with tape, and the label is pasted on the front of the carton. Multiple cartons can be stacked on a pallet, and the pallet is wrapped with stretch film to ensure stability.
Transportation Methods:
Road Transportation: It is the most commonly used transportation method, suitable for short and medium distances. The wire is transported by trucks, and the type of truck is selected according to the quantity and packaging of the wire. For small batches of carton-packaged wires, light-duty trucks can be used; for large batches of reel-packaged wires, medium and heavy-duty trucks with flatbeds or containers are used. The truck compartment must be clean, dry, and free of sharp objects to avoid damaging the packaging and the wire.
Railway Transportation: It is suitable for long-distance and large-volume transportation. The wire is usually transported in containers, which can provide a good protective environment, avoiding the influence of weather factors such as rain and snow. Railway transportation has the advantages of large capacity, stable speed, and low cost, which is suitable for bulk goods transportation.
Sea Transportation: It is mainly used for export products or long-distance transportation across regions. The wire is packed in containers, and the container is checked for tightness to prevent seawater or moisture from entering. Sea transportation has a low cost but a long cycle, so it is necessary to reasonably arrange the transportation time to ensure that the goods arrive on schedule.
Transportation Precautions:
Loading and Unloading: Mechanical equipment such as forklifts and cranes should be used for loading and unloading to avoid manual rough handling. When lifting reel-packaged wires, special lifting tools should be used to hook the center hole of the reel to prevent the reel from being damaged. For carton-packaged wires, they should be lifted from the bottom to prevent the carton from being torn. During loading, the wires should be arranged neatly, and the heavy ones should be placed at the bottom and the light ones on top to avoid crushing.
Protection from External Factors: During transportation, the wire should be protected from direct sunlight, rain, and snow. If transported by open trucks, it should be covered with a waterproof and sunshade cloth. In high-temperature weather, attention should be paid to ventilation to prevent the insulation layer from aging due to high temperature; in low-temperature weather, there is no need for special thermal insulation measures because the wire can withstand low temperatures, but it should avoid violent impact to prevent the insulation layer from becoming brittle and cracking.
