4×25mm² Cable: This cable consists of 4 Conductors with a cross-sectional area of 25mm², featuring a compact overall structure. Under the voltage level of 0.6/1kV, its continuous current-carrying capacity is relatively stable. Usually, at a suitable ambient temperature (such as 25°C), the current-carrying capacity can reach a certain value, which can meet the power transmission needs of small and medium power. The thickness of its insulation layer meets relevant standards, which can effectively insulate current and ensure electrical safety. At the same time, the outer diameter of the cable is moderate, making it easy to lay in narrow spaces.

4×35mm Cable: It contains 4 conductors with a cross-sectional area of 35mm. Compared with the 4×25mm² cable, the cross-sectional area of the conductor is increased. This makes its current-carrying capacity increase accordingly. Under the same environmental conditions, the current-carrying capacity is higher than that of the 4×25mm² cable, and it can adapt to power transmission of larger power. Its insulation performance is also reliable and can withstand a voltage of 0.6/1kV. The overall mechanical strength of the cable is also good, and it can cope with general installation and use environments.

4×150mm Cable: It is composed of 4 conductors with a cross-sectional area of 150mm, belonging to a larger specification cable. At the 0.6/1kV voltage level, it has a strong current-carrying capacity and can meet the requirements of high-power power transmission. Its insulation layer has good voltage resistance and mechanical properties, and can maintain a stable insulation effect in relatively complex environments. In addition, parameters such as the bending radius of the cable are also specified to ensure that it will not be damaged due to excessive bending during installation.

Model-Related Parameters: Although the specific parameters of models such as U-1000, Ar2V, Axmk, Na2xy, Na2xh, Na2xh-J, Axv, and Yakxs are not fully clear, it is inferred from the model identifiers that different models may have differences in Insulation Materials, protective performance, etc. For example, some models may use special insulation materials, making them perform better in terms of temperature resistance and aging resistance; some models may have optimized structural designs, with certain tensile and impact resistance capabilities.

4×25mm² Cable: Due to its small cross-section and moderate current-carrying capacity, it is suitable for small and medium-power scenarios. In the distribution branch lines of small buildings, such as the internal distribution lines of small office buildings and small shopping malls, it can stably transmit electricity from the distribution box to various electrical terminals. It can also meet the needs of power connections for some small industrial equipment, such as small machine tools and small fans. In addition, in the renovation of indoor distribution lines in families, this cable is often used for the main line or the dedicated line power supply of important electrical appliances.

4×35mm Cable: The improved current-carrying capacity enables it to be competent for scenarios such as power supply for medium-sized equipment and building trunk lines. In terms of medium-sized industrial equipment, it can provide stable power support for injection molding machines, pulverizers and other equipment. In building trunk lines, such as the distribution trunk lines of multi-storey residential buildings and the main power supply lines of floors in medium-sized hotels, it can transmit electricity efficiently. At the same time, it can also play a good role in some small outdoor power distribution projects, such as the main power supply lines for street lamps in residential quarters.

4×150mm Cable: Its large cross-section and strong current-carrying capacity make it suitable for high-power transmission scenarios. In the main lines of industrial workshops, such as the main power supply lines of workshops in large machinery factories and chemical plants, it can meet the power needs of many large-scale equipment operating at the same time. In the main distribution trunk lines of large buildings, such as large commercial complexes and high-rise buildings, it can undertake the important task of power distribution. In addition, it can also stably transmit electricity in the outgoing lines of some power distribution stations.

Characteristic Uses of Cables of Different Models: The U-1000 model cable may have good versatility and is suitable for various ordinary power distribution scenarios. If the Ar2V and Axmk models have weather resistance, they can be used for outdoor power transmission lines, such as power supply for outdoor billboards and road monitoring equipment. If the Na2xy and Na2xh models have flame-retardant properties, they are suitable for use in places with high fire protection requirements, such as the distribution lines of hospitals and schools. The Na2xh-J model may have optimization in some special structures and is suitable for specific installation environments. The Axv and Yakxs models may have advantages in wear resistance and corrosion resistance, and can be used in some industrial places with relatively harsh environments.

Conductor Material: These cables are likely to use copper or Aluminum Conductors in terms of material. Copper Conductors have excellent electrical conductivity, low resistance, and low loss during power transmission. Moreover, copper has good mechanical properties, high toughness, and is not easy to break, so it is suitable for use in scenarios with high requirements for electrical conductivity. Aluminum Conductors are relatively light in weight and low in cost, which have certain advantages in some occasions sensitive to weight and cost. At the same time, they also have certain electrical conductivity and corrosion resistance.

Insulation Layer Material: The insulation layer of the cable uses corresponding insulation materials, which may include polyvinyl chloride (PVC), cross-linked polyethylene (XLPE), etc. The polyvinyl chloride insulation layer has good insulation performance, wear resistance and processing performance, and the price is relatively affordable, which can meet the insulation needs of general scenarios. The cross-linked polyethylene insulation layer has better heat resistance, aging resistance and mechanical strength, and can maintain stable insulation performance in a higher temperature environment, which is suitable for some occasions with higher insulation requirements.

Style Design: Most of them are of 4-core design, which can transmit electricity and ensure safety at the same time. They may include phase lines, neutral lines and ground lines, meeting the power distribution needs of three-phase four-wire systems, etc. The appearance of the cable is usually round or flat with a smooth surface, which is convenient for laying and installation. Cables of different models may have differences in the material and color of the outer sheath. For some cables with special properties, their sheaths may use weather-resistant, flame-retardant and other materials, and the color may also be designed according to the needs of the use scenario. For example, cables used outdoors may adopt dark sheaths to resist ultraviolet radiation.

Conductor Production: For Copper Conductors, first, copper materials are smelted, rolled and other processes to make copper rods, then the copper rods are drawn into Copper Wires of the required diameter through a wire drawing process, and then stranded as needed to form conductors. The production of aluminum conductors is similar. First, aluminum materials are processed into aluminum rods, and then conductors are made through wire drawing, stranding and other processes. During the production process, the size and performance of the conductor will be strictly controlled to ensure that its electrical conductivity meets the requirements.

Insulation Layer Extrusion: The extrusion molding process is used to wrap the insulation layer around the conductor. Appropriate extrusion temperature, speed and other parameters are set according to different insulation materials. During the extrusion process, it is necessary to ensure that the insulation layer is evenly wrapped on the surface of the conductor without defects such as bubbles and impurities to ensure insulation performance. For the cross-linked polyethylene insulation layer, cross-linking treatment is also required. The insulation material molecules are formed into a cross-linked structure by heating and other methods to improve their performance.

Cabling Process: The 4 conductors wrapped with insulation layers are cabled according to a certain stranding method. During the stranding process, it is necessary to ensure that the positions of the conductors are stable to avoid mutual friction and extrusion. At the same time, a layer of filling material may be wrapped around the cabled cable to make the cable structure more round.

Sheath Extrusion: The sheath is extruded on the outside of the cabled cable, and the sheath material is selected according to the performance requirements of the cable. During the extrusion process, it is necessary to ensure that the sheath has a uniform thickness and is tightly combined with the internal structure to protect the internal conductors and insulation layers. Finally, the cable is cooled, solidified and other treatments to make it 成型.

Inspection Process: During and after production, the cable will undergo a series of inspections, including conductor resistance test, insulation resistance test, voltage withstand test, appearance and size inspection, etc., to ensure that all performance indicators of the cable meet relevant standards and requirements.

Packaging Materials: The packaging of these cables usually selects appropriate packaging materials according to the specifications and length of the cables. For cables with shorter lengths, plastic reels or cartons may be used for packaging. Plastic reels are light and have certain protection, and cartons are convenient for stacking and transportation. For cables with longer lengths, wooden or steel cable reels are mostly used. Wooden cable reels have relatively low cost, while steel cable reels have strong load-bearing capacity and high strength, which can better protect the cables from damage during transportation and storage.

Packaging Method: The cable is neatly wound on the reel or cable reel, and appropriate tension is maintained during the winding process to avoid loosening or twisting of the cable. A layer of moisture-proof film or plastic cloth may be wrapped around the outer layer of the cable to prevent the cable from getting damp and contaminated with dust. For wooden and steel cable reels, protective devices will be installed on their edges and sides to prevent the cables from being hit during transportation. At the same time, the model, specification, length, manufacturer, production date and other information of the cable will be clearly marked on the packaging for easy identification and traceability.

Packaging Requirements: The packaging should be firm and reliable, able to withstand external forces such as bumps and 挤压 during transportation, and prevent the cable from moving, wearing or being damaged in the packaging. The packaging should have good moisture-proof and dust-proof performance to prevent the cable from being affected by the external environment and reducing its performance. For exported cables, the packaging also needs to comply with the packaging standards and regulations of relevant countries and regions.

Transportation Method: Select an appropriate transportation method according to factors such as the quantity, specification and transportation distance of the cable. Truck transportation can be used for short-distance transportation. Truck transportation has high Flexibility and can directly deliver the cable to the destination. For long-distance transportation, railway transportation or long-distance road transportation can be chosen. Railway transportation has a large carrying capacity and good stability, which is suitable for the transportation of large quantities of cables. For cables that need to be exported, sea transportation can also be used.

Transportation Precautions: During transportation, avoid the cable from being squeezed, collided, exposed to the sun, rained on, frozen, etc. The cable should be placed stably and fixed firmly during loading to prevent rolling, tilting or falling during transportation. Cables of different specifications and models should be stacked separately to avoid mutual extrusion and friction. For cables with cable reels, ensure that the cable reels rotate flexibly to avoid damaging the cables due to jamming of the cable reels during transportation. The transport vehicle should be kept clean to prevent the cable from being contaminated by oil, debris, etc.

Transportation Marks: Marks such as "Handle with Care", "Moisture-proof", "Sun-proof" and "No Rolling" are marked in obvious positions of the transport vehicle to remind transport personnel to pay attention to the correct transportation and loading and unloading methods. At the same time, the model, specification, quantity, destination and other information of the cable are indicated on the transportation documents for checking and management during transportation.

Delivery Process: After receiving the customer's order, the staff will check the order information in a timely manner, including the model, specification, quantity, delivery address of the cable, etc., to ensure that the information is accurate. Then go to the warehouse to retrieve the corresponding cable, conduct an appearance inspection and quantity count of the cable, and package it after confirmation. Contact the transportation company, arrange the transport vehicle and transportation time, hand over the packaged cable to the transportation company, and go through relevant transportation procedures. Finally, timely inform the customer of the delivery information, such as the name of the transportation company, the transportation order number, and the estimated arrival time, to facilitate the customer to track the dynamics of the goods.
