The specification parameters of Nayy Nyy Nyy-J 4X95mm² and 4X120mm² grounded Power Cables are rigorous and diverse, providing solid technical support for their wide application in low-voltage distribution systems.

In terms of conductor specifications, the 4X95mm² cable consists of 4 Conductors with a cross-sectional area of 95mm², while the 4X120mm² cable contains 4 conductors of 120mm². The cross-sectional area here refers to the cross-sectional area of the conductor, which directly affects the current-carrying capacity of the cable. The cross-sectional area designs of 95mm² and 120mm² are precisely determined according to the needs of different power transmission scenarios, and can be adapted to medium-power and higher-power electricity scenarios respectively.

Current-carrying capacity is one of the key performance parameters of this cable. The current-carrying capacity of the 4X95mm² cable is approximately 200-250A, and this range of current-carrying capacity enables it to meet the needs of medium-power power transmission such as the operation of small and medium-sized equipment and workshop lighting systems. The current-carrying capacity of the 4X120mm² cable can reach 250-300A, which is sufficient to support the stable power supply of high-power equipment such as large production equipment, central air conditioners, and elevators. It is worth noting that the current-carrying capacity will be affected by factors such as ambient temperature and laying methods, and reasonable consideration should be given to specific conditions in practical applications.

In terms of rated voltage, the rated voltage of this cable is 0.6/1kV, and this voltage level makes it fully compatible with low-voltage distribution networks. 0.6kV refers to the rated power frequency voltage between the Cable Conductor and the shielding layer, and 1kV is the rated power frequency voltage between the cable conductors. This design ensures that the cable can operate safely and stably in low-voltage distribution systems, covering power distribution needs in industrial, civil, commercial and other fields.

In addition, the outer diameter of the cable is also an important specification parameter. Due to the different cross-sectional areas of the conductors, there is a difference in the outer diameters of the 4X95mm² and 4X120mm² cables. Generally speaking, the outer diameter of the 4X120mm² cable is larger than that of the 4X95mm² cable. The size of the outer diameter will affect the laying method and installation space of the cable. When planning cable laying, this parameter needs to be fully considered to ensure the smooth progress of the installation process.

The cable is equipped with a dedicated Grounding Wire, and the cross-sectional area of the grounding wire is also clearly specified, usually matched according to the specifications of the main conductor, to ensure that in case of equipment leakage or short circuit, the current can be quickly introduced into the ground, playing an effective safety protection role. The material of the grounding wire is the same as that of the main conductor to ensure its conductivity and durability.

Nayy Nyy Nyy-J 4X95mm² and 4X120mm² grounded power cables, with their excellent performance and reasonable specification design, have distinctive applications in many fields, providing reliable guarantees for power transmission in different scenarios.

It is used to connect large production equipment, such as heavy machine tools and large compressors, as well as the power distribution trunk lines of production lines. These equipment have high power and extremely high requirements for power stability. The sufficient current-carrying capacity of the 4X120mm² cable can ensure the continuous and stable supply of power, guarantee the normal operation of production equipment, and reduce production interruptions caused by power supply problems. The 4X95mm² cable is suitable for small and medium-sized equipment, such as small processing machine tools and ventilation equipment in the workshop, and can also be used for power supply of the workshop lighting system, meeting the electricity needs of different areas in the workshop and making the power distribution in the entire industrial production environment orderly.

Commercial buildings are another important application scenario for this cable. In shopping malls, 4X120mm² cables are often used for power distribution trunk lines of high-power equipment such as central air conditioning systems, escalators, and large refrigeration equipment. These equipment are crucial for the normal operation of the mall, and their stable operation is inseparable from continuous and sufficient power supply. 4X95mm² cables can be used for branch power distribution of ordinary lighting, cash register systems, and small ventilation equipment in the mall, ensuring stable power supply in various areas of the mall and providing customers with a comfortable shopping environment. In office buildings, the situation is similar. 4X120mm² cables are responsible for powering elevators, central air conditioning hosts, etc., while 4X95mm² cables meet the electricity needs of lighting, computers, printers and other office equipment in the office, ensuring the smooth progress of office work.

In the civil field, the distribution system of residential communities is highly dependent on this cable. From the community's distribution room to the main switch of each building, 4X120mm² cables are usually selected because they can carry the power load of the entire building and efficiently transmit power from the distribution room to the building. From the main switch of the building to the distribution box of each unit, 4X95mm² cables are mostly used, and then the unit distribution box distributes power to each household, ensuring that electrical equipment in residents' homes can be used normally and providing stable power guarantee for residents' daily lives.

This cable is also often used in temporary power supply scenarios in municipal engineering. In road construction, municipal facility maintenance and other projects, it is necessary to temporarily build power supply systems to provide power for construction equipment, lighting equipment, etc. Due to the complex environment of these projects, there are high requirements for the durability and safety of the cable. The PVC Sheath of Nayy Nyy Nyy-J power cable has good wear resistance and weather resistance, which can adapt to harsh outdoor environments. At the same time, the design of the grounding wire also ensures the electrical safety of construction personnel.

Outdoor landscape lighting is also inseparable from the support of this cable. The landscape lighting systems in parks, squares, scenic spots and other places need to transmit power to various lighting fixtures. The 4X95mm² cable has become an ideal choice due to its appropriate current-carrying capacity and good weather resistance. It can work stably in outdoor environments for a long time, ensuring the normal operation of the landscape lighting system and creating a beautiful and comfortable night environment for people.

Nayy Nyy Nyy-J 4X95mm² and 4X120mm² grounded power cables, in terms of material selection and style design, fully combine performance requirements and practical application scenarios, showing significant advantages.

In terms of Conductor Materials, the cable uses high-purity copper or aluminum as the conductor material according to different models. High-purity Copper Conductors have extremely excellent conductivity, with low resistance, small energy loss during current transmission, and can efficiently transmit power to electrical equipment, which is very suitable for scenarios with high requirements for power transmission efficiency. At the same time, Copper Conductors also have good ductility and toughness, which are easy to process and install, and can adapt to a certain degree of bending and stretching during laying. Aluminum Conductors have more advantages in terms of cost and lightweight. Under the same specification, the weight of Aluminum Conductors is much lighter than that of copper conductors, which not only reduces the transportation cost of the cable but also makes the installation process more convenient and labor-saving. Although the conductivity of aluminum conductors is slightly inferior to that of copper conductors, aluminum conductors are very suitable for some scenarios where the requirements for conductivity are not extremely high and cost is more sensitive. Both copper and aluminum conductors can ensure stable current transmission and meet the electricity needs of different scenarios.

Both the insulation layer and the sheath are made of PVC (polyvinyl chloride) material. PVC material has excellent insulation performance, which can effectively prevent current leakage and ensure the safety of power transmission. It has extremely strong wear resistance, and can resist external friction and collision during cable laying, handling and use, protecting the internal conductors from damage. At the same time, PVC material also has good chemical corrosion resistance, which can resist the erosion of various chemical substances such as acids, alkalis and oils, enabling the cable to maintain stable performance in complex environments.

In terms of style, the cable is overall black. The black sheath not only has good weather resistance, can adapt to outdoor environmental factors such as sun, rain, high and low temperature changes, and prolong the service life of the cable, but also can reduce light reflection, making the cable not too conspicuous in the installation environment and reducing the impact on the aesthetics of the surrounding environment. The structure of the cable is compact and reasonable. 4 main conductors and 1 grounding wire are arranged in an orderly manner, and the outside is wrapped with a PVC Insulation layer and a sheath, forming a solid whole. This structural design not only ensures the Flexibility of the cable, facilitating laying in different installation environments, but also enhances the mechanical strength of the cable, enabling it to withstand a certain degree of external impact.

In addition, the cable has clear and standardized marks. The sheath surface is printed with product model, specification, rated voltage, manufacturer and other information. These marks not only facilitate users to identify and select suitable cables, but also provide convenience for cable installation, maintenance and management.

The production process of Nayy Nyy Nyy-J 4X95mm² and 4X120mm² grounded power cables is exquisite and strict, and each link is carefully controlled to ensure that the product quality and performance meet relevant standards and requirements.

The production of conductors is the first step in the entire process. For copper conductors, high-purity electrolytic copper is first selected as the raw material, and copper rods are made through smelting, ingot casting and other processes. Then, the copper rod is drawn into Copper Wires of the required diameter by a wire drawing machine. During the wire drawing process, it is necessary to accurately control the drawing speed, temperature and lubrication conditions to ensure that the copper wires have uniform diameter, smooth surface, and good mechanical properties and conductivity. For aluminum conductors, high-purity aluminum ingots also need to be selected, processed into aluminum rods through a series of processes, and then drawn into Aluminum Wires through a wire drawing process. After that, according to the specification requirements of the cable, multiple copper wires or Aluminum Wires are stranded to form a conductor with the required cross-sectional area. During the stranding process, it is necessary to ensure that the stranding pitch is uniform to ensure the roundness and flexibility of the conductor.

Next is the extrusion of the insulation layer. PVC material is added to the extruder, heated and melted, and then uniformly coated on the surface of the Stranded Conductor through a mold to form an insulation layer. During the extrusion process, it is necessary to accurately control the extrusion temperature, pressure and speed, which directly affect the quality of the insulation layer. Excessively high temperature may cause decomposition of the PVC material, affecting the insulation performance; excessively low temperature may cause the insulation layer to not bond tightly with the conductor, resulting in bubbles or cracks. At the same time, the thickness of the insulation layer must be uniform, and the thickness deviation must be controlled within the specified range to ensure the stability of the insulation performance.

After the extrusion of the insulation layer, the cabling process is carried out. 4 conductors with insulation layers and 1 grounding wire are cabled according to a certain stranding method. During stranding, it is necessary to ensure that the positions of the conductors are uniform and the tension is consistent to avoid uneven stress in subsequent processes. During the cabling process, some auxiliary materials, such as filling ropes, are also filled between the conductors to ensure the roundness of the cabled cable, facilitating the subsequent extrusion of the sheath.

After cabling, the sheath is extruded. PVC material is also used. It is melted by an extruder and coated on the outside of the cabled core to form a sheath. The process requirements for sheath extrusion are similar to those for the insulation layer. Various parameters need to be strictly controlled to ensure that the sheath has uniform thickness, smooth surface, and is tightly bonded to the internal core. The thickness of the sheath must meet relevant standards to provide sufficient mechanical protection and weather resistance.

During the production process, a number of quality inspections are also required. In the conductor production stage, parameters such as conductor diameter, resistance, and tensile strength are tested; after the insulation layer is extruded, the thickness, insulation resistance, and voltage resistance of the insulation layer are tested; after cabling and sheath extrusion, the overall outer diameter, sheath thickness, voltage resistance, and mechanical properties of the cable are comprehensively tested. Only cables that meet the standard requirements in all testing items can be judged as qualified products and enter the subsequent packaging and sales links.

In addition, the control of the production environment is also crucial. The production workshop needs to be kept clean and dry to avoid dust, impurities, etc. affecting the cable quality. At the same time, production equipment needs to be regularly maintained and calibrated to ensure the accuracy and stability of the equipment, providing a guarantee for the production of high-quality cables.

The packaging design of Nayy Nyy Nyy-J 4X95mm² and 4X120mm² grounded power cables fully considers the characteristics of the product and the needs of transportation and storage, aiming to protect the cable from damage during the entire circulation process and ensure the quality and performance of the product.

For coiled cables, wooden cable reels are usually used for packaging. Wooden cable reels have the characteristics of high strength and good stability, and can provide solid support for the cables. The size of the cable reel is designed according to the length and specification of the cable to ensure that the cable can be neatly wound on it, avoiding twisting, folding or loosening. When winding the cable, it is necessary to control the winding tension to make the cable arranged tightly, reducing shaking and friction during transportation.

The two sides of the cable reel are equipped with solid baffles, and the height of the baffles is higher than the winding height of the cable to prevent the cable from slipping during transportation and handling. Metal hooks or holes are usually installed on the baffles to facilitate handling with forklifts, cranes and other equipment. At the same time, a detailed label is pasted on the side of the cable reel, which clearly indicates the product name, model specification, length, rated voltage, production batch number, production date, implementation standard, manufacturer name and contact information, etc., facilitating users to identify and accept the product.

In order to prevent the cable from getting damp and contaminated during storage and transportation, the outer layer of the cable is wrapped with a moisture-proof and dust-proof plastic film. The plastic film should be closely attached to the surface of the cable without gaps, which can effectively block moisture, dust, impurities, etc. from entering the cable, protecting the insulation layer and conductors of the cable from damage. For cable reels with long length and heavy weight, steel strips are used to firmly fix the cable on the cable reel to further enhance the stability of the packaging and prevent the cable from loosening due to vibration during transportation.

For exported cables, the packaging also needs to comply with international transportation standards and the import requirements of relevant countries. For example, wooden cable reels need to be fumigated and accompanied by a fumigation certificate to prevent the spread of diseases and pests. The labels on the packaging need to be in English or the official language of the destination country to ensure that the information can be accurately understood.

During storage, packaged cables should be stored in a dry, ventilated, dark warehouse away from heat sources and corrosive substances. The cable reel should be placed on a flat ground and padded with wooden blocks to prevent the cable reel from getting damp due to direct contact with the ground. At the same time, it is necessary to avoid stacking heavy objects on the cable reel to prevent damage to the cable.

The transportation process of Nayy Nyy Nyy-J 4X95mm² and 4X120mm² grounded power cables needs to strictly follow relevant regulations and operating procedures to ensure the safety and integrity of the cable and avoid product damage due to improper transportation.

Before transportation, a comprehensive inspection of the cable packaging is required. Carefully check whether the cable reel is firm, whether the baffle is intact, whether the cable is wound neatly and tightly, whether the label is clear and complete, and whether the plastic film is well sealed. If the packaging is found to be damaged or loose, it needs to be repaired or repackaged in time until it meets the transportation requirements.

Select appropriate transport vehicles according to the specification, quantity and transportation distance of the cable. For short-distance transportation, ordinary trucks can be used; for long-distance transportation, semi-trailers or special transport vehicles are more suitable. The carriage of the transport vehicle should be kept clean and flat, without sharp debris, to prevent scratching the cable packaging and sheath. When loading the cable, use a forklift or crane to smoothly lift the cable reel into the carriage, and be careful to avoid collision and extrusion of the cable reel during lifting. The cable reel should be placed reasonably in the carriage to ensure stable center of gravity. Usually, the central axis of the cable reel is consistent with the driving direction of the vehicle to reduce the impact of centrifugal force during transportation.

In order to prevent the cable reel from rolling and colliding during transportation, it is necessary to firmly fix it in the carriage with steel wire ropes or chains. The fixed points should be selected on the special fixing devices of the vehicle. The tension of the steel wire ropes or chains should be moderate, which should ensure that the cable reel does not move and not be over-tightened to damage the cable reel or cable. For simultaneous transportation of multiple cable reels, a certain gap should be left between the cable reels, and partitions should be used to separate them to avoid mutual friction and collision.

During transportation, drivers must strictly abide by traffic rules, maintain stable driving, avoid violent operations such as sudden braking, sharp turns and speeding, and reduce the impact and vibration on the cable. When passing through bumpy sections, bridges, tunnels and other special sections, drive slowly to ensure

driving safety and the stability of the cable. At the same time, attention should be paid to protecting the cable from severe weather. In case of rain or snow, the cable should be covered to prevent it from getting damp; in hot weather, the cable should be avoided from being exposed to the sun for a long time to prevent the sheath from aging due to high temperature.

Special personnel should be arranged for escort during transportation. The escorts should be familiar with the characteristics and transportation requirements of the cable, regularly check the fixing status and packaging of the cable, and deal with problems in a timely manner. If transportation is delayed due to traffic jams, road maintenance, etc., the recipient should be informed in time of the expected arrival time.

After arriving at the destination, appropriate equipment should be used to unload the cable reel from the carriage smoothly. During unloading, collision and extrusion of the cable should be avoided. After unloading, the escorts and the recipient should jointly inspect the packaging, appearance and labels of the cable. After confirmation, the handover procedures should be handled.
