The specification parameters of 1.5mm²/2.5mm² Flexible Copper wires are carefully designed to accurately meet the medium and low-load power demand in different scenarios, providing a solid guarantee for the stable operation of various electrical equipment.

The conductor of the 1.5mm² wire is made by stranding multiple fine copper wires with a diameter of 0.15mm. Through precise stranding technology, the overall cross-sectional area reaches 1.5mm². This structure of multiple fine copper wires not only endows the wire with good Flexibility but also ensures the stability of its conductive performance. At room temperature, the DC resistance of this wire is ≤12.1Ω/km. The low resistance value means less loss during current transmission, which can effectively improve the efficiency of power transmission. Its allowable continuous current-carrying capacity is 16A, which is fully capable of supporting the stable power supply of lighting fixtures and small household appliances (such as microwave ovens, vacuum cleaners, electric fans, etc.). Whether it is the lighting in the living room and bedroom at home, or the small appliances in the kitchen and bathroom, the 1.5mm² wire can handle them easily.

The 2.5mm² wire is stranded with thicker copper wires. Its conductor is also composed of multiple copper wires, with an overall cross-sectional area of 2.5mm². Compared with the 1.5mm² wire, the 2.5mm² wire has stronger conductivity. At room temperature, its DC resistance is ≤7.41Ω/km, and the current-carrying capacity is increased to 25A. This enables it to meet the power demand of high-power household appliances such as air conditioners, electric water heaters, and electric ovens. In homes, kitchens and bathrooms usually use more high-power appliances, and the 2.5mm² wire can provide stable and reliable power support for these appliances, avoiding tripping and equipment damage caused by insufficient current-carrying capacity of the wire.

Both wires have a rated voltage of 450/750V, which is much higher than the 220V standard voltage commonly used in homes and offices. The higher rated voltage provides sufficient safety margin for voltage fluctuations. Even when the grid voltage fluctuates instantaneously, it can effectively prevent the insulation layer from being damaged due to overvoltage, thus ensuring the safe operation of the entire circuit system.

In addition, the insulation thickness of the 1.5mm² wire is 0.8mm, and that of the 2.5mm² wire is 1.0mm. The uniform insulation thickness can ensure that the wire has good insulation performance, effectively block the current, and prevent electric leakage accidents. The outer diameter of the wire also varies with specifications. The outer diameter of the 1.5mm² wire is about 3.2mm, and that of the 2.5mm² wire is about 4.0mm. The small outer diameter makes it more flexible in the wiring process and can adapt to the installation needs of narrow spaces.

In terms of temperature performance, the long-term allowable operating temperature of the wire is 70℃, which can meet the usage requirements of most households, offices, and small industrial environments. Even when the equipment runs for a long time and the temperature rises, the wire can maintain stable performance and will not age or be damaged due to high temperature. The maximum temperature during a short circuit (with a maximum duration of no more than 5 seconds) does not exceed 160℃. This parameter ensures that the wire will not be damaged quickly in special cases such as short circuits, buying valuable time for fault handling.

1.5mm²/2.5mm² Flexible Copper Wires, relying on their unique performance characteristics, have a wide range of distinctive uses in many fields such as households, offices, and small industries.

In the household field, 1.5mm² wires and 2.5mm² wires perform their respective duties to ensure the safety and stability of household electricity use. 1.5mm² wires are often used in lighting circuits and socket branch lines. In each room of the home, the power of lighting fixtures is relatively small, and 1.5mm² wires can meet their power transmission needs. At the same time, for some sockets with low power, such as sockets in the bedroom for charging mobile phones and tablets, 1.5mm² wires can also be used as branch lines, which is both economical and practical. 2.5mm² wires play an important role in areas with concentrated high-power appliances such as kitchens and bathrooms, leading the main circuits in these areas. Appliances such as electric ovens, microwave ovens, and rice cookers in the kitchen, as well as electric water heaters and bathroom heaters in the bathroom, all require large current support. The high current-carrying capacity of 2.5mm² wires can ensure the normal operation of these appliances and avoid affecting their use due to insufficient power.

In office scenarios, 1.5mm²/2.5mm² Flexible Copper Wires also perform well. Equipment in the office such as printers, projectors, computers, and water dispensers all need stable power supply. The power of these equipment is mostly at medium and low levels, and both types of wires can meet their needs. Due to the relatively compact spatial layout of the office and dense equipment placement, the flexible characteristics of the wires enable them to be hidden and routed along narrow spaces such as gaps between desks and cabinets, which not only keeps the office environment clean and beautiful but also avoids the risk of the wires being stepped on or collided and damaged. For example, in an open office area, wires can be laid along the edge of the carpet or in the trunking without affecting people's walking and the normal use of office equipment.

Small industrial environments are also important application scenarios for this wire. In some small factories or workshops, control lines of small industrial machinery such as assembly line conveyor motors, small air compressors, and ventilation equipment usually choose 1.5mm²/2.5mm² flexible copper wires. These equipment may produce slight vibrations during operation. The flexibility and toughness of the wires enable them to withstand the line pulling caused by such vibrations, ensuring the stable transmission of control signals and the normal operation of the equipment. At the same time, in the wiring process of the workshop, the wires can flexibly bypass various machinery and obstacles, reducing the difficulty of wiring and improving construction efficiency.

In addition, in some temporary electricity scenarios, such as outdoor small activities, temporary lighting at construction sites, and power supply for small equipment, 1.5mm²/2.5mm² flexible copper wires can also play an important role. Their flexible design makes the wires easy to carry and arrange, and can quickly set up temporary power supply lines to meet temporary electricity needs.

In terms of material selection and style design, 1.5mm²/2.5mm² flexible copper wires are fully combined with their performance requirements and application scenarios, making them have good flexibility, insulation, and durability.

In terms of materials, the conductor uses high-purity electrolytic copper as the raw material. High-purity electrolytic copper has excellent conductivity, which can ensure the smooth transmission of current and reduce energy loss. At the same time, electrolytic copper has good ductility and toughness. After stranding, it can form a soft and unbreakable conductor structure, providing a basic guarantee for the flexibility of the wire.

The insulation layer is made of polyvinyl chloride (PVC) material. PVC material has many excellent characteristics, making it an ideal choice for wire insulation layers. Firstly, it has excellent corrosion resistance, which can resist the erosion of moisture, dust, and slight chemical substances in the daily environment, effectively protecting the conductor from damage and prolonging the service life of the wire. Secondly, PVC material has good insulation performance, with an insulation resistance of ≥100MΩ, which can effectively block current, prevent electric leakage accidents, and ensure electrical safety. In addition, PVC material also has a certain mechanical strength, which can withstand a certain degree of external impact and friction, protecting the internal conductor from damage.

In terms of style, the wire adopts a single-core structure, with a layer of uniform PVC Insulation layer wrapped around the outer layer. The single-core structure makes the wire more flexible, facilitating bending and arrangement in narrow spaces. The color of the insulation layer is usually common colors such as black, white, and red. Wires of different colors can be used to distinguish different circuits and uses, which is convenient for construction personnel to identify during installation and maintenance. For example, red wires can be used for live wires, blue wires for neutral wires, and yellow-green 双色 wires for Ground Wires. This color distinction helps ensure the correctness of circuit connections and improves electrical safety.

The surface of the wire is smooth and flat, without burrs and protrusions, which not only helps reduce friction resistance during wiring, avoids damage to the insulation layer, but also makes the wire smoother during pipe laying, reducing construction difficulty. At the same time, the surface of the wire is printed with clear marks, including wire specifications, rated voltage, certification marks (such as GB/T 5023.3 standard certification marks), and meter scales. These marks are printed with wear-resistant printing technology, which can remain clearly distinguishable during long-term use, facilitating construction personnel to quickly identify and operate during cutting and installation, and improving construction efficiency.

Each roll of wire is available in two specifications: 100 meters and 200 meters. This specification design can meet the needs of different construction scenarios. For small home decoration or local wiring, 100-meter wires may be more suitable; for overall wiring in large office spaces or workshops, 200-meter wires can reduce the number of joints and improve the reliability of the line.

The production process of 1.5mm²/2.5mm² flexible copper wires is rigorous and meticulous. Every link from raw material processing to finished product inspection is strictly controlled to ensure that the product quality meets relevant standards and requirements.

The first step is the processing of copper materials. High-purity electrolytic copper ingots are selected as raw materials, heated to a molten state, and then made into copper rods through continuous casting process. The quality of copper rods directly affects the performance of subsequent wires. Therefore, during the casting process, parameters such as temperature and casting speed need to be accurately controlled to ensure the purity, diameter uniformity, and surface quality of copper rods.

Next is the wire drawing process of copper rods. The copper rod is drawn through a wire drawing machine, and through a series of dies of different specifications, the copper rod is drawn into fine copper wires with a diameter of 0.15mm. During the drawing process, the copper wire will be subjected to a large pulling force. In order to eliminate the internal stress of the copper wire and improve its flexibility and ductility, the drawn copper wire needs to be annealed. Annealing is usually carried out in an annealing furnace. The copper wire is heated to a certain temperature and kept for a period of time, then slowly cooled, so that the crystal structure of the copper wire is more uniform and the performance is more stable.

Then is the stranding of copper wires. According to the specification requirements of the wire, multiple strands of fine copper wires are stranded according to a certain stranding method and pitch to form a 1.5mm² or 2.5mm² conductor. The stranding process is a key link to ensure the flexibility of the wire. By reasonably designing the stranding pitch and the number of strands, the conductor can have good flexibility and fatigue resistance, ensuring that the wire can maintain the integrity and conductivity of the conductor after repeated bending. 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 conductivity.

After stranding, enter the insulation layer extrusion process. PVC particles are added to the extruder, heated and melted to form a molten melt. At the die head of the extruder, the molten PVC melt is evenly extruded and wrapped around the Stranded Conductor 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 uniform thickness, smooth surface, and is closely combined with the conductor without defects such as bubbles and impurities. The thickness of the insulation layer must be strictly controlled according to the design requirements. The insulation layer thickness of the 1.5mm² wire is 0.8mm, and that of the 2.5mm² wire is 1.0mm to ensure that the wire has good insulation performance.

The wire after extrusion molding needs to be cooled, usually by water cooling. The wire is introduced into the cooling water tank, and through the rapid cooling effect of cold water, the PVC insulation layer is quickly solidified and shaped to ensure the dimensional stability and performance stability of the wire. The cooled wire is tested by a spark tester, and through high-voltage electrical testing, it is checked whether the insulation layer has defects such as pinholes and damage to ensure that the insulation performance of the insulation layer meets the requirements. If defective wires are found, they need to be marked and repaired or scrapped.

Subsequently, the wire enters the traction and take-up process. The traction machine pulls the wire at a constant speed to ensure uniform tension of the wire and avoid the wire being stretched or damaged due to excessive tension. The take-up machine neatly winds the wire on the reel to form a 100-meter or 200-meter coiled product. During the take-up process, it is necessary to control the take-up speed and tension to ensure that the wire is arranged tightly and neatly on the reel without looseness or entanglement, which is convenient for transportation, storage, and use.

During the production process, sampling tests are also required on various properties of the wire, including the DC resistance of the conductor, the thickness of the insulation layer, voltage resistance performance, insulation resistance, flexibility, etc. These tests can timely find problems in the production process and take corresponding measures for rectification to ensure the stability and consistency of product quality. At the same time, the environment of the production workshop also needs to be strictly controlled to keep the workshop clean and hygienic, avoiding the impact of dust, impurities, etc. on product quality.

The packaging design of 1.5mm²/2.5mm² flexible copper wires fully considers the needs of product protection, transportation, storage, and use, ensuring that the wires remain in good condition before reaching the user.

Wires are usually packaged with hard paper reels or plastic reels. For 100-meter wires, smaller reels are generally used; for 200-meter wires, larger reels are used. The material selection of the reel takes into account both strength and cost. Hard paper reels have the characteristics of environmental protection and low cost, while plastic reels have better moisture resistance and durability.

When the wire is wound on the reel, mechanical winding is adopted to ensure that the wire is arranged neatly and tightly to avoid mutual extrusion and wear. After winding, a layer of transparent plastic film is 套在 the outside of the reel, which can play the role of moisture-proof, dust-proof, and anti-pollution, protecting the insulation layer of the wire from the influence of the external environment. At the same time, the plastic film can also prevent the wire from loosening and falling off the reel during transportation and storage.

On the side or end face of the reel, there will be a detailed product label pasted or printed, which clearly marks the product name, specification (1.5mm² or 2.5mm²), rated voltage (450/750V), length (100 meters or 200 meters), certification mark (such as GB/T 5023.3), manufacturer name, production date, batch number, etc. This information is convenient for users to check when receiving and accepting products, ensuring that the received products meet the order requirements.

For products transported in batches, multiple reels will be neatly stacked on wooden pallets or cartons. Wooden pallets have the characteristics of strong bearing capacity and easy forklift handling, suitable for the transportation of large batches of products; cartons are suitable for the transportation of small batches of products, with the advantages of light weight and easy stacking. During stacking, partitions or buffer materials will be placed between the reels to reduce mutual collision and friction and further protect the products.

In addition, the selection of packaging materials also considers environmental factors, and tries to choose recyclable and degradable materials to reduce environmental pollution. For example, hard paper reels and cartons can be recycled and reused, and plastic films are also made of recyclable polyethylene materials. At the same time, in the packaging process, excessive packaging is avoided to save packaging materials and reduce packaging costs.

The transportation process of 1.5mm²/2.5mm² flexible copper wires needs to strictly abide by relevant regulations and operating procedures to ensure that the products are not damaged during transportation and arrive at the destination safely.

In terms of transportation mode selection, road transport, railway transport, or express transport can be chosen according to the transportation distance, quantity, and customer requirements. Road transport has the characteristics of high flexibility, fast transportation speed, and door-to-door service, suitable for medium and short-distance transportation and small-batch cargo transportation. For long-distance transportation and large quantities of goods, railway transport is a more economical choice. Railway transport has the advantages of large transport capacity, low cost, and little impact from weather. Express transport is suitable for small batches and urgent orders, which can provide faster transport speed and convenient services.

Before transportation, the packaged wires need to be properly fixed. For wires packaged with reels, when loading into transport vehicles or containers, they should be neatly stacked together and fixed with ropes or strapping to prevent shaking, collision, and dumping during transportation. For products stacked on wooden pallets, the pallets and products should be tightly wrapped together with stretch film to enhance the overall stability.

During transportation, effective protective measures should be taken to prevent the wires from direct sunlight, rain, snow, and high-temperature exposure. Direct sunlight and high-temperature exposure will cause the temperature of the wires to rise, which may affect the performance of the insulation layer; rain and snow will make the wires damp, reducing their insulation performance and service life. Therefore, during transportation, transport vehicles or containers need

to be covered with tarpaulins or other protective materials to shield the wires from harsh weather conditions. In addition, the wires should be kept away from sharp objects and corrosive substances to prevent the insulation layer from being scratched or corroded, which could compromise the wire's performance.

Transport vehicles must adhere to traffic rules during transit, maintaining a steady speed and avoiding sudden braking, sharp turns, or overspeeding. These actions help minimize impact and vibration on the wires, reducing the risk of damage to the reels or the wires themselves. For long-distance transportation, drivers or transport personnel should periodically inspect the condition of the wires, checking for any signs of loosening, damage to the packaging, or exposure to adverse weather. Any issues identified should be addressed promptly to ensure the continued safety of the cargo.

When loading and unloading the wires, proper equipment such as forklifts or hand trucks should be used to handle the reels. Manual handling of heavy reels is discouraged to prevent personal injury and damage to the wires. During the loading and unloading process, care must be taken to avoid dropping or impact the reels, as this could cause deformation of the reels or damage to the wire's insulation layer. Reels should be lifted and placed gently, ensuring they are properly aligned and secured in the transport vehicle or storage area.

If the products are in stock, they proceed with order processing; if not, the production department is notified to schedule manufacturing, with a commitment to completing production within the agreed timeframe based on the order volume.

Before shipping, each reel of wire undergoes a thorough inspection. Warehouse personnel verify that the product specifications (1.5mm² or 2.5mm²), length (100m or 200m), and rated voltage (450/750V) match the order details. They also inspect the packaging for any damage, ensuring the plastic film is intact and the reel is not cracked or deformed. Additionally, a random check of the wire's surface and insulation layer is conducted to ensure there are no defects such as scratches, bulges, or tears.

Once the inspection is completed, the wires are prepared for shipment. The warehouse team coordinates with the selected logistics provider to arrange for pickup. For small orders, the wires are often shipped via express courier, with tracking information provided to the customer immediately upon dispatch.
