I. From the Perspective of the Product Itself
(1) Specification Parameters
The 1.5mm², 2.5mm², and 4mm² PVC insulated
Copper Cables (
Stranded Conductors) show a clear stepwise progression in their specification parameters, precisely adapting to electrical equipment of different powers and providing stable power transmission guarantees for various circuits.
The conductor of the 1.5mm² cable is stranded with multiple strands of high-purity electrolytic
Copper Wires with a diameter of 0.15mm. Through a scientific stranding process, the overall cross-sectional area of the conductor reaches 1.5mm². This multi-strand stranded structure not only enhances the
Flexibility of the conductor but also effectively disperses the current, reducing losses caused by the skin effect. At room temperature, its DC resistance is ≤12.1Ω/km, and the low resistance value ensures minimal energy loss during current transmission. The allowable continuous current-carrying capacity of this specification cable is 16A, which is fully capable of meeting the power supply needs of lighting fixtures and small household appliances (such as table lamps, electric fans, TVs, set-top boxes, etc.). For example, a commonly used 40W fluorescent lamp in a household has a working current of approximately 0.18A. Even if multiple lamps work simultaneously, the total current is far lower than 16A, and the 1.5mm² cable can easily handle it.
The conductor of the 2.5mm² cable is stranded with thicker copper wires, with a single wire diameter larger than that of the 1.5mm² cable, and the overall cross-sectional area after stranding is 2.5mm². Its DC resistance at room temperature is ≤7.41Ω/km, and the reduction in resistance further reduces energy loss during current transmission. The allowable continuous current-carrying capacity is increased to 25A, which can meet the power demand of medium-power appliances such as air conditioners (generally 1-1.5 horsepower, with a working current of approximately 4-7A), electric water heaters (power of approximately 1500-2000W, working current of approximately 6.8-9.1A), and microwave ovens (power of approximately 800-1500W, working current of approximately 3.6-6.8A). Taking the simultaneous use of an air conditioner and an electric water heater as an example, the total current is approximately 10-16A, which is much lower than the 25A current-carrying capacity, and the 2.5mm² cable can stably ensure their power supply.
The conductor of the 4mm² cable has a larger cross-sectional area, consisting of multiple strands of thicker copper wires stranded together, with an overall cross-sectional area of 4mm². At room temperature, its DC resistance is ≤4.61Ω/km, and the lower resistance further reduces energy loss during current transmission. The allowable continuous current-carrying capacity reaches 32A, which can carry larger power equipment such as central air conditioners (power of approximately 2-3 horsepower, working current of approximately 9-13.6A) and small industrial machinery (such as small lathes, milling machines, etc., working current of approximately 10-20A). Even if multiple high-power devices work simultaneously, as long as the total current does not exceed 32A, the 4mm² cable can stably transmit power to ensure the normal operation of the devices.
All three cables have a rated voltage of 300/500V. This voltage level can not only meet the needs of common 220V AC circuits in homes and offices but also withstand possible voltage fluctuations in daily power grid operation, providing sufficient voltage margin for circuit safety. When the grid voltage has a short-term increase or fluctuation, the cable will not have faults such as insulation layer breakdown due to voltage issues.
In terms of insulation layer thickness, the insulation layer of the 1.5mm² cable is 0.8mm, that of the 2.5mm² cable is 0.9mm, and that of the 4mm² cable is 1.0mm. As the cable specification increases, the thickness of the insulation layer gradually increases, which can provide more reliable insulation protection for cables carrying larger currents to adapt to the more complex electrical environment they may face. The insulation resistance of all three cables is ≥100MΩ. The high insulation resistance ensures that there is almost no current leakage in the cable under normal working conditions, effectively preventing electric shock accidents and ensuring electrical safety.
In addition, all three cables comply with the GB/T 5023.3 standard certification. Their material selection, production processes, performance indicators, etc., have undergone strict inspections and meet the national quality standards, providing users with reliable quality assurance. At the same time, they can all withstand a long-term working temperature of 70℃ and a short-term short-circuit temperature of 160℃, and can maintain stable performance under normal use and sudden short-circuit conditions.
(2) Characteristic Uses
The 1.5mm², 2.5mm², and 4mm² PVC insulated copper cables (stranded conductors) play important roles in different electrical scenarios with their respective performance characteristics, having distinct characteristic uses.
Due to its moderate current-carrying capacity and thin wire diameter, the 1.5mm² cable is widely used in lighting circuits of residential buildings and office buildings. In home decoration, the power supply lines of living room chandeliers, spotlights, bedroom downlights, ceiling lamps, kitchen and bathroom lighting fixtures, etc., mostly use 1.5mm² cables. These lighting fixtures have relatively low power, and the 16A current-carrying capacity of the 1.5mm² cable is fully capable of meeting the demand. At the same time, its thin wire diameter is convenient for concealed laying in narrow spaces such as inside walls and ceiling interlayers, without affecting the overall aesthetics of the decoration. For example, when laying in the ceiling suspended ceiling, the 1.5mm² cable can easily pass through the keel gaps and connect with the lamp junction box, achieving beautiful and safe wiring.
In addition to lighting circuits, the 1.5mm² cable is also often used as switch control lines. In homes and offices, the connection lines between switches of various lamps and appliances and the equipment usually use 1.5mm² cables. Since the current transmitted in the switch control lines is small, the performance of the 1.5mm² cable is sufficient to meet the requirements, and it has good flexibility, which is convenient for connecting and wiring between the switch panel and the equipment in the wall, reducing construction difficulty.
The 2.5mm² cable is widely used in socket circuits due to its larger current-carrying capacity. In areas such as the living room, bedroom, kitchen, and bathroom of a home, the power supply lines of ordinary wall sockets and multi-functional sockets mostly use 2.5mm² cables. These sockets need to be connected to various appliances, such as living room TVs, stereos, vacuum cleaners, bedroom air conditioners, electric heaters, kitchen refrigerators, microwave ovens, rice cookers, bathroom washing machines, hair dryers, etc. The 25A current-carrying capacity of the 2.5mm² cable can meet the current demand when these appliances work simultaneously.
Especially in areas such as kitchens and bathrooms that need to be connected to high-power appliances, the advantages of the 2.5mm² cable are more obvious. Kitchen appliances such as electric water heaters and microwave ovens have relatively high power, and the current is large when used simultaneously. The 2.5mm² cable can stably transmit power, avoiding safety hazards caused by line overload. The environment in the bathroom is relatively humid, and the insulation layer of the 2.5mm² cable has good moisture resistance, which can work reliably in such an environment, ensuring the safe use of electricity for appliances such as washing machines and electric water heaters.
Due to its large current-carrying capacity, the 4mm² cable mainly undertakes the task of dedicated line power supply for high-power equipment. In villas and high-end residences, the main line of central air conditioners usually uses 4mm² cables to meet their large power demand. Central air conditioners have high power and high operating current, and the 32A current-carrying capacity of the 4mm² cable can ensure their stable operation without problems such as line overheating.
In small industrial facilities, 4mm² cables also have important applications. The
Power Lines of lathes, milling machines, drilling machines and other small industrial machinery in small workshops mostly use 4mm² cables. These machines have large currents during operation, and the 4mm² cable can provide stable power transmission for them, ensuring the normal operation of the machinery. In addition, some small industrial air compressors, water pumps and other equipment also often use 4mm² cables as power supply lines.
All three cables support exposed or concealed laying methods. When exposed, they can be directly fixed along walls, ceilings, etc., with convenient installation; when concealed, they can be threaded into pipes and buried in walls, floors, or ceilings, making the lines more concealed and maintaining a clean and beautiful environment. They are compatible with various installation methods such as pipe threading, wall embedding, and cable 桥架，and can adapt to different building structures and decoration styles, meeting diversified wiring needs.
(3) Material and Style
In terms of material selection and style design, the 1.5mm², 2.5mm², and 4mm² PVC insulated copper cables (stranded conductors) are fully combined with the performance requirements and use scenarios of the products, ensuring the high quality and practicality of the cables.
In terms of materials, the conductors all use high-purity electrolytic copper. Electrolytic copper undergoes refining treatment, with a purity of up to 99.9% or more, and has excellent conductivity, which can ensure smooth current transmission and reduce energy loss. High-purity electrolytic copper also has good ductility and toughness. After stranding processing, it can form a soft and unbreakable conductor structure, making the cable have good flexibility, which is convenient for bending and laying in various complex environments. At the same time, electrolytic copper has good oxidation resistance, is not easy to be oxidized and corroded during long-term use, can maintain stable conductivity, and prolong the service life of the cable.
The insulation layer is made of weather-resistant polyvinyl chloride (PVC) material. PVC material has excellent insulation performance, which can effectively block current, prevent short-circuit accidents when the cable is in contact with other conductors, and ensure electrical safety. This material has good temperature resistance, can work stably for a long time in the ambient temperature of -15℃ to 70℃, and can adapt to temperature changes in home, office and small industrial environments. In addition, the
PVC Insulation layer also has a certain degree of chemical corrosion resistance, which can resist the erosion of moisture, dust, grease and other substances in the daily environment, and protect the internal conductor from damage. At the same time, it has good mechanical strength, can withstand a certain degree of external extrusion and friction, and is not easy to be damaged during construction and use.
In terms of style design, all three cables have a single-core stranded structure, that is, a conductor made of multiple strands of copper wire stranded together is wrapped with a layer of PVC insulation, with a simple and compact structure. This single-core stranded structure makes the cable more flexible in the wiring process, especially when laying through pipes, it can easily pass through pipes with smaller diameters, reducing construction difficulty.
The cables have various appearance colors, commonly white, black, gray, etc. Different colors are convenient for distinguishing different line functions in circuit wiring. For example, white can be used for live wires, black for neutral wires, gray for
Ground Wires, etc. This color distinction helps construction personnel accurately identify the lines during installation, avoids safety hazards caused by wrong line connections, and improves the standardization and safety of circuit layout.
The surface of the cable is smooth and flat, without burrs, protrusions and other defects. This design not only makes the cable more beautiful in appearance but also reduces the frictional resistance with other objects during construction, facilitates pipe threading and laying, and reduces the risk of damage to the insulation layer. At the same time, the smooth surface is also easy to clean and not easy to accumulate dust and dirt.
Each roll of cable has two specifications of length: 100 meters and 200 meters. The 100-meter specification is suitable for small decoration projects, partial line transformation and other scenarios, which can reduce material waste; the 200-meter specification is more suitable for large construction projects, large-area wiring and other needs, reducing the number of joints, lowering the possibility of failures caused by joint problems, and improving the reliability of the circuit.
The surface of the cable is printed with clear marks, including specification parameters (1.5mm², 2.5mm² or 4mm²), rated voltage (300/500V), certification marks (such as GB/T 5023.3), manufacturer name, production date, meter scale, etc. These marks are printed with wear-resistant printing technology, which can remain clearly distinguishable during long-term use and construction, facilitating construction personnel to check and operate during cutting and installation, and ensuring the accuracy and efficiency of construction.
(4) Production Process
The production process of 1.5mm², 2.5mm², and 4mm² PVC insulated copper cables (stranded conductors) is rigorous and complex. Each link from raw material processing to finished product inspection undergoes strict quality control to ensure that the products meet relevant standards and requirements.
The first step is the processing of copper materials. High-purity electrolytic copper ingots are selected as raw materials and heated to a molten state, with the temperature controlled at around 1083℃ to completely melt the copper ingots. Then, through a continuous casting process, the molten copper is introduced into a special mold and cooled to form copper rods. During the casting process, parameters such as casting speed and cooling water temperature need to be accurately controlled to ensure uniform diameter, smooth surface, and dense internal structure of the copper rods, avoiding defects such as air holes and cracks. The quality of the copper rods directly affects the performance of subsequent conductors, so this link is crucial.
Next is the wire drawing process of the copper rods. The copper rods are put into a wire drawing machine and drawn through a series of dies of different specifications. The aperture of the wire drawing die gradually decreases, and the copper rod is drawn through the die under tension, with the diameter gradually reducing, and finally drawn into fine copper wires of different diameters. Among them, the diameter of the copper wire for the 1.5mm² cable is 0.15mm, and the diameter of the copper wire for the 2.5mm² and 4mm² cables is correspondingly larger. During the drawing process, the copper wire will produce a certain degree of work hardening. In order to eliminate internal stress and improve the flexibility and ductility of the copper wire, the drawn copper wire needs to be annealed. Annealing is carried out in an annealing furnace. The copper wire is heated to 300-500℃ and kept for a certain time, then slowly cooled to restore the crystal structure of the copper wire to be stable and improve its performance.
Then is the stranding of copper wires. According to the requirements of different specifications of cables, multiple strands of fine copper wires are stranded by a stranding machine according to a certain stranding pitch to form a conductor with the required cross-sectional area. The design of the stranding pitch should be reasonable. If the pitch is too small, it will increase the rigidity of the conductor and affect flexibility; if the pitch is too large, it will lead to a loose conductor structure and affect mechanical strength. During the stranding process, it is necessary to ensure that the tension of each strand of copper wire is uniform and arranged neatly to ensure the roundness of the conductor and the uniformity of conductive performance. The surface of the stranded conductor should be smooth, without burrs, broken wires and other defects. For 1.5mm² cables, the number of copper wire strands required is relatively small; while for 2.5mm² and 4mm² cables, due to the larger cross-sectional area, more copper wire strands are required.
After stranding, the insulation layer is extruded. PVC
Insulation Material particles are added to the hopper of the extruder, and the material is transported to the heating area through the rotation of the screw. In the extruder, the PVC particles are heated to 160-180℃ and melted into a flowable melt. The molten PVC melt is evenly extruded and wrapped on the surface of the stranded
Copper Conductor through the die of the extruder head to form an insulation layer. During the extrusion process, it is necessary to accurately control the extrusion temperature, extrusion speed and die size to ensure that the insulation layer has a uniform thickness (0.8mm for 1.5mm² cable, 0.9mm for 2.5mm² cable, 1.0mm for 4mm² cable), a smooth surface, and is closely combined with the conductor, without defects such as bubbles, impurities, and depressions.
The cable after extrusion of the insulation layer needs to be cooled. Water cooling is usually used. The cable is introduced into a cooling water tank, and the PVC insulation layer is quickly solidified and shaped through rapid cooling with cold water to ensure the dimensional stability and performance stability of the cable. The cooled cable is tested by a spark tester. A certain high voltage is applied to the surface of the cable to check whether the insulation layer has defects such as pinholes and damage, ensuring that the insulation performance of the insulation layer meets the requirements (insulation resistance ≥100MΩ).
Subsequently, the cable enters the traction and take-up process. The traction machine pulls the cable at a constant speed to ensure uniform tension of the cable and avoid the cable being stretched or damaged due to excessive tension. The take-up machine neatly winds the cable on the reel to form 100-meter or 200-meter coiled products. During the take-up process,
it is necessary to control the take-up speed and tension to ensure that the cable is tightly and neatly arranged on the reel, facilitating transportation, storage, and use.
During the production process, sampling inspections of the cables are also required, covering multiple indicators such as the DC resistance of the conductor, the thickness of the insulation layer, voltage resistance performance, insulation resistance, and flexibility. Only cables that meet the requirements of the GB/T 5023.3 standard in all indicators can be delivered as finished products. At the same time, the production workshop must maintain cleanliness to avoid the impact of dust, impurities, etc. on product quality, ensuring that the produced PVC insulated copper cables have stable and reliable performance.
II. From the Perspective of General Product Information
(1) Packaging
The packaging design of 1.5mm², 2.5mm², and 4mm² PVC insulated copper cables (stranded conductors) fully considers the needs of product protection, transportation, storage, and use, ensuring that the cables remain in good condition during circulation.
The cables are packaged in rolls, with each roll available in two lengths: 100 meters and 200 meters. The reels are usually made of hard paper or plastic materials. Paper reels are low in cost and have good environmental protection, being recyclable, in line with the concept of green development; plastic reels have better moisture resistance and wear resistance, suitable for storage and transportation in humid environments, and can better protect the cables from moisture.
When the cables are wound onto the reels, mechanical automatic winding is adopted. This method can ensure that the cables are arranged neatly and tightly, avoiding mutual extrusion, entanglement, and wear between the cables. During the winding process, by precisely controlling the winding tension, the cables form a stable roll structure on the reels, preventing loosening during transportation and storage.
After winding, a layer of transparent plastic film is 套在 over the outside of the reel. This layer of plastic film has good sealing performance and can play the role of moisture-proof, dust-proof, and anti-pollution. It can prevent moisture, dust, etc. in the air from entering the surface of the cable, protect the insulation layer from erosion, and at the same time prevent the cable from being damaged by slight collisions and friction from the outside during handling.
A detailed label is pasted on the side or end face of the reel. The label clearly indicates the product name (PVC insulated copper cable (stranded conductor)), specification parameters (1.5mm², 2.5mm², or 4mm²), rated voltage (300/500V), length (100 meters or 200 meters), certification marks (GB/T 5023.3), manufacturer name, production date, batch number, etc. This information is convenient for users to check when receiving and accepting the products, ensuring that the received products are consistent with the order requirements, and also provides a basis for product quality traceability.
For cables transported in batches, multiple reels are neatly stacked on wooden pallets or sturdy cartons. Wooden pallets have strong bearing capacity, facilitating loading, unloading, and handling with forklifts, improving transportation efficiency, and are suitable for long-distance transportation of large quantities of products; cartons are suitable for transportation of small quantities of products, being light in weight, easy to manually handle and stack, and low in cost. During stacking, partitions or buffer materials (such as foam boards, bubble films, etc.) are placed between the reels to reduce mutual collision and friction, further protecting the products from damage.
The selection of packaging materials focuses on environmental protection and recyclability, minimizing environmental pollution. Paper reels, cartons, and other packaging materials can be recycled and reused, and plastic films are also made of recyclable materials, in line with the requirements of modern society for environmentally friendly packaging. At the same time, on the premise of ensuring product safety, excessive packaging is avoided, saving packaging materials and reducing packaging costs.
(2) Transportation
The transportation process of 1.5mm², 2.5mm², and 4mm² PVC insulated copper cables (stranded conductors) needs to strictly abide by relevant regulations and operating procedures to ensure that the products are safely and timely delivered to the destination.
The choice of transportation method depends on the transportation distance, quantity, and customer needs. For short-distance transportation (such as within a city or surrounding areas), road transportation is usually adopted. Road transportation has the characteristics of high flexibility, fast transportation speed, and can achieve door-to-door service, which can quickly deliver products to customers, suitable for small batches and urgent orders. For long-distance transportation (such as across provinces and cities), railway transportation can be chosen. Railway transportation has the advantages of large transportation capacity, low cost, and little impact from weather, which can ensure the stable transportation of goods. For export products or orders with special requirements, sea freight or air freight can also be used. Sea freight is suitable for large quantities of non-urgent goods with low cost; air freight is fast, suitable for urgent orders, but the cost is relatively high.
Before transportation, the packaged cables need to be properly fixed. For cables packaged with reels, when loading into transport vehicles or containers, they should be placed stably and fixed in the carriage with ropes, strapping, etc., to prevent the reels from shaking, toppling, or colliding with each other due to vehicle bumps, turns, etc. during transportation. For cables stacked on wooden pallets, the pallets and reels should be tightly wrapped together with stretch film to enhance the overall stability and avoid scattering during transportation.
During transportation, effective protective measures should be taken to prevent the cables from direct sunlight, rain, snow, and high-temperature exposure. Direct sunlight and high-temperature exposure will cause the cable temperature to rise, which may cause aging and softening of the PVC insulation layer, affecting its insulation performance and mechanical strength; rain and snow will make the cables damp, leading to a decrease in insulation resistance, affecting the power transmission performance, and may even cause aging and damage to the insulation layer. Therefore, during transportation, transport vehicles or containers need to be covered with tarpaulins, etc., to protect the cables from harsh weather. At the same time, the cables should be kept away from sharp objects and corrosive substances to prevent the insulation layer from being scratched or corroded, ensuring that the performance of the cables is not affected.
Transport vehicles must abide by traffic rules during driving, maintain stable driving, avoid sudden braking, sharp turns, overspeeding, etc., to reduce the impact and vibration on the cables. For long-distance transportation of cables, drivers or transport personnel should conduct regular inspections. They need to check whether the fixing of the cables is loose, whether the packaging is damaged, and whether there is any sign of moisture or contamination on the surface of the cables. If any problems are found, timely measures should be taken to deal with them, such as re-fixing the loose cables, replacing the damaged packaging, or wiping the contaminated cable surfaces, to ensure that the cables remain in good condition during transportation.
In the process of loading and unloading, appropriate equipment and tools should be used, such as forklifts, cranes, or hand trucks, to avoid manual handling of heavy reels. Manual handling not only easily causes damage to the cables but also may lead to personal injury. When using loading and unloading equipment, it is necessary to operate carefully to avoid collision or extrusion between the reels and the equipment or between the reels themselves. The reels should be lifted and placed gently to ensure that they are stably placed in the transport vehicle or storage area, preventing them from tipping over or falling during transportation.
