Cu XLPE Swa PVC 16mm2 16 Sq mm Copper Armoured Cable 4 Core 25mm Price

The specification parameters of Cu XLPE Swa PVC 16mm² and 25mm² 4-Core Copper Armoured Cables are the basis for their performance and application, and each parameter is carefully designed and strictly regulated.

In terms of conductors, "Cu" represents high-purity electrolytic Copper Conductors, and 16mm² and 25mm² refer to the cross-sectional area of a single conductor. This parameter directly determines the current-carrying capacity of the cable. Under normal circumstances, the 16mm² conductor can usually meet the needs of medium-power equipment, with a current-carrying capacity of about 40-50A; while the 25mm² conductor has a larger current-carrying capacity, up to 60-70A, which can carry the current load of higher-power equipment such as large industrial machinery. The conductor has extremely high purity and low resistivity, ensuring efficient current transmission and reducing energy loss. At the same time, the 4-core design enables it to meet the three-phase four-wire power supply system, among which three are phase wires and one is a neutral wire. This structure is very common in power transmission and large-scale equipment power supply, and can ensure stable power distribution.

The insulation layer is made of XLPE (cross-linked polyethylene) material, which has excellent temperature resistance. The long-term working temperature can reach 90°C, and the short-term overload temperature can even reach 130°C, which is much higher than the temperature resistance level of traditional PVC Insulation. This allows the cable to maintain good insulation performance in high-temperature environments, greatly expanding its application range. The thickness of the insulation layer is also strictly regulated. The thickness of the insulation layer of 16mm² and 25mm² cables is set according to relevant standards to ensure that it can effectively isolate current under the rated voltage (usually 0.6/1kV) and prevent safety hazards such as electric leakage.

"Swa" refers to the Steel Tape armouring layer, and its specifications are also closely related to the overall performance of the cable. The thickness and number of layers of the steel tape are determined according to the cross-sectional area of the cable and the use scenario. The steel tape armouring layer of 16mm² and 25mm² cables can provide sufficient mechanical strength to resist external extrusion, impact and damage from rodents. The existence of the armouring layer enables the cable to have good resistance to mechanical damage, and is suitable for environments that are prone to external interference such as direct burial and bridge laying.

The outer sheath is made of PVC material, and its thickness is also strictly calculated. It not only protects the internal armouring layer and insulation layer from the erosion of natural factors such as moisture and ultraviolet rays, but also enhances the overall Flexibility and wear resistance of the cable. The PVC Sheath also has good chemical corrosion resistance, which can resist the influence of acids, alkalis and other chemical substances to a certain extent, and prolong the service life of the cable.

In addition, parameters such as the overall outer diameter and weight of the cable also have clear standards. The 16mm² cable has a relatively small outer diameter and light weight, which is more convenient to lay in some limited space scenarios; the 25mm² cable has a larger outer diameter and weight due to the larger specifications of the conductor and armouring layer, but it can meet the power transmission needs of higher power. These parameters comply with the International Electrotechnical Commission (IEC) or relevant national standards, ensuring the safety and reliability of the cable in various application scenarios.

Cu XLPE Swa PVC 16mm² and 25mm² 4-core copper Armoured Cables have irreplaceable characteristic uses in many fields due to their unique performance.

In the industrial field, 16mm² cables are suitable for power transmission of small and medium-sized industrial equipment, such as small motors and power distribution systems of workshop production lines. These equipments have moderate power, and the current-carrying capacity of 16mm² cables can meet their needs. At the same time, the steel tape armouring layer can protect the cables from mechanical damage in the complex environment of the factory. For example, in the workshop, the cables may be affected by external forces such as collisions during equipment handling and falling tools, and the armouring layer can effectively reduce these risks. 25mm² cables are often used in large industrial machinery, such as heavy machine tools and large compressors. These equipments have high power and high requirements for the stability and safety of power transmission. The large current-carrying capacity and solid structure of 25mm² cables can provide reliable power support for them.

This type of cable is also widely used in municipal engineering. In outdoor buried laying scenarios, such as underground transmission lines of street lamp systems, cables need to withstand soil pressure, groundwater immersion and possible external excavation for a long time. The water resistance and corrosion resistance of the XLPE insulation layer and the mechanical damage resistance of the steel tape armouring layer enable the cable to work stably in such an environment for a long time. In tunnel engineering, due to the closed space, humid environment and possible mechanical vibration, the safety and durability of cables are crucial. This series of cables can well adapt to these conditions to ensure the power supply of lighting, ventilation and other equipment in the tunnel.

The power distribution trunk of high-rise buildings is also an important application scenario. High-rise buildings have extremely high requirements for the reliability of power supply. As the main road of power transmission, the power distribution trunk needs to have good performance. 16mm² cables can be used for branch power distribution in the floor, and 25mm² cables are suitable for the main line from the distribution room to the main distribution box of each floor. Its 4-core design meets the needs of three-phase four-wire power supply, which can ensure the balanced distribution of power on each floor. At the same time, the moisture resistance of the PVC sheath and the mechanical strength of the steel tape armouring can cope with various environmental challenges that may occur in high-rise buildings, such as humid pipe wells and collisions caused by personnel activities.

In commercial complexes, the cable acts as the main cable from the distribution room to each floor. There are many equipments in commercial complexes, including air conditioning systems, elevators, lighting equipments, electrical equipments in various shops, etc., with large and complex power loads. 16mm² and 25mm² cables are used in a reasonable combination according to different load requirements to ensure stable power transmission. Moreover, due to its steel tape armouring feature, no additional pipe protection is required, which reduces the installation difficulty and cost in the limited space of the commercial complex, and also reduces the safety hazards caused by improper pipe installation.

In some special environments, such as chemical plants and coastal areas, this series of cables can also play a role. There may be corrosive gases or liquids in chemical plants, and the chemical corrosion resistance of XLPE insulation layer and PVC sheath can provide certain protection; the air humidity in coastal areas is high and the salt content is high, so the moisture resistance and corrosion resistance of cables are also important, which can effectively extend the service life of cables.

Cu XLPE Swa PVC 16mm² and 25mm² 4-core copper armoured cables fully combine performance requirements and ease of use in material selection and style design.

In terms of materials, the conductor is made of high-purity electrolytic copper, which has excellent conductivity, can transmit current efficiently and reduce energy loss. High-purity copper also has good ductility and flexibility, making the conductor not easy to break during processing and laying, ensuring the overall quality of the cable. Compared with conductors of other materials, Copper Conductors have better oxidation resistance, which can maintain stable conductivity during long-term use and prolong the service life of the cable.

The insulation layer uses XLPE (cross-linked polyethylene) material. After cross-linking treatment, its molecular structure forms a three-dimensional network structure, which greatly improves the heat resistance, mechanical strength and chemical corrosion resistance of the material. Compared with traditional PVC Insulation Materials, XLPE insulation layer is not easy to soften at high temperature, and its insulation performance is more stable, so it can be used in harsher environments. At the same time, XLPE material has a small dielectric constant and large insulation resistance, which further reduces the energy loss of the cable and improves the efficiency of power transmission.

The steel tape armouring layer is made of high-quality low-carbon steel tape, which has high mechanical strength and toughness. After processing, the low-carbon steel tape has good corrosion resistance, which can protect the internal structure of the cable from external mechanical damage. The steel tapes of the armouring layer are closely combined to form a solid protective layer, which can effectively resist both the pressure of the soil during direct burial and the collision during bridge laying.

The outer sheath is made of PVC (polyvinyl chloride) material, which has good flexibility, wear resistance and weather resistance. It can be tightly wrapped around the armouring layer to prevent moisture, dust, etc. from entering the cable, and at the same time play a certain buffering role to reduce the impact of external shocks on the internal structure. The PVC sheath also has certain flame retardant performance. In case of fire, it can delay the spread of the fire and gain time for personnel evacuation and fire fighting.

In terms of style design, the cable has a circular structure, which makes the cable more smooth during laying, reducing resistance whether it is 穿管 or direct burial. The circular structure also makes the force of the cable more uniform. When subjected to external extrusion, the force can be distributed to the entire circumference, reducing the risk of local damage.

The color of the cable is usually designed according to industry standards and use scenarios. Generally speaking, the sheath color is mostly black, which has good UV resistance and is suitable for outdoor use. At the same time, clear marks will be printed on the surface of the cable, including model, specification, rated voltage, manufacturer and other information, which is convenient for users to identify and use.

The difference in style between 16mm² and 25mm² cables is mainly reflected in the overall outer diameter and weight. Due to the larger specifications of the conductor and armouring layer, the 25mm² cable has a relatively larger outer diameter and weight, but the structural design and material selection principles of the two are consistent, aiming to meet performance requirements and ease of use.

The production process of Cu XLPE Swa PVC 16mm² and 25mm² 4-core copper armoured cables is complex and rigorous, and each link has an important impact on the quality of the cable.

Conductor manufacturing is the first step in production. High-purity electrolytic copper rods are used as raw materials, and the copper rods are drawn into Copper Wires of the required diameter through a wire drawing process. During the wire drawing process, it is necessary to strictly control the wire drawing speed, temperature and die size to ensure that the diameter of the copper wire is uniform, the surface is smooth, and defects such as cracks and scratches are avoided. The drawn copper wire is annealed to eliminate internal stress, improve the flexibility and ductility of the copper wire, and facilitate the subsequent stranding process. Then, multiple copper wires are stranded together according to a certain stranding method to form a conductor with the required cross-sectional area. During the stranding process, the tension must be uniform to ensure the stable structure of the conductor and improve its mechanical strength and conductivity.

The insulation layer extrusion process is one of the key links. The XLPE material is heated to a molten state, and evenly wrapped on the surface of the conductor through an extruder to form an insulation layer. During the extrusion process, it is necessary to accurately control the extrusion temperature, pressure and speed to ensure that the thickness of the insulation layer is uniform, the surface is smooth, and it is closely combined with the conductor without bubbles, impurities and other defects. After extrusion, the XLPE material needs to be cross-linked, usually by warm water cross-linking or steam cross-linking, so that the linear molecular structure is transformed into a three-dimensional network structure, thereby improving the performance of the insulation layer. Parameters such as temperature and time of cross-linking treatment need to be strictly controlled to ensure that the cross-linking degree meets the requirements.

The cabling process is to strand four conductors with insulation layers together to form a cable core. Stranding must be carried out according to a certain pitch to ensure the roundness and stability of the cable core. At the same time, during the stranding process, some non-hygroscopic materials may be filled to ensure that the structure of the cable core is tight and prevent moisture from entering.

The steel tape armouring process is to wrap the steel tape around the outside of the cable core to form an armouring layer. First, the steel tape is pretreated, such as derusting and painting, to improve its corrosion resistance. Then, the steel tape is wrapped around the cable core at a certain angle and tension through an armouring machine. There must be a certain overlap between the steel tapes to ensure the continuity and tightness of the armouring layer. During the armouring process, it is necessary to avoid wrinkles and fractures of the steel tape to ensure the mechanical strength of the armouring layer.

Finally, the sheath extrusion process is to heat and melt the PVC material, and evenly wrap it around the armouring layer through an extruder to form the outer sheath. The parameter control during the extrusion process is similar to that of the insulation layer extrusion. It is necessary to ensure that the thickness of the sheath is uniform, the surface is smooth, and it is closely combined with the armouring layer. After extrusion, the sheath needs to be cooled and shaped to ensure its dimensional stability.

Throughout the production process, quality inspection runs through. There are strict standards and procedures from the incoming inspection of raw materials, to the in-process inspection of each process, to the final inspection of finished products. Inspection items include the diameter and resistivity of the conductor, the thickness and voltage resistance of the insulation layer, the thickness of the armouring layer, the thickness and tensile strength of the sheath, etc., to ensure that each batch of cables meets relevant standards and requirements. Only cables that have passed strict inspection can leave the factory for sale.

The packaging design of Cu XLPE Swa PVC 16mm² and 25mm² 4-core copper armoured cables aims to protect the product, facilitate transportation and storage, and take into account clear identification and environmental protection requirements.

For coiled cables, wooden or steel cable reels are usually used for packaging. The size of the cable reel is determined according to the length and diameter of the cable to ensure that the cable can be neatly wound on it to avoid loosening and 缠绕. The structure of the cable reel is firm, which can bear the weight of the cable and the external impact during transportation, and protect the cable from damage. During the cable winding process, a layer of isolation paper or film will be placed between each layer of cables to prevent friction between cables and avoid scratches on the sheath.

Baffles will be installed on both sides of the cable reel to prevent the cable from slipping off from the side. Relevant product information will be clearly printed on the baffle, including model, specification, length, rated voltage, manufacturer, production date, implementation standard, etc., which is convenient for users to identify and check the product during receiving and storage. At the same time, some precautions for handling and storage will be marked on the baffle, such as "Do not invert" and "Handle with care".

For short-length cables, wooden boxes or pallets may be used for packaging. The cables are neatly placed in wooden boxes or fixed on pallets, and bound and fixed with ropes or steel tapes to prevent movement and collision during transportation. The materials of wooden boxes and pallets also have certain strength and can protect the cables.

In order to prevent the cable from getting damp during transportation and storage, a layer of waterproof plastic film will be wrapped around the cable reel or package, especially in rainy or humid environments, this protective measure is more important. The waterproof film should be wrapped tightly to ensure that rainwater, moisture, etc. cannot enter the package.

The selection of packaging materials also takes into account environmental protection requirements, and recyclable and degradable materials are used as much as possible, such as wooden cable reels and paper isolation materials, to reduce environmental pollution. At the same time, in the packaging design, we will strive to be simple and reasonable, avoid excessive packaging, and reduce packaging costs and resource waste.

The transportation of Cu XLPE Swa PVC 16mm² and 25mm² 4-core copper armoured cables needs to strictly abide by relevant regulations and operating procedures to ensure the safety and integrity of the cables during transportation.

The choice of transportation mode is determined according to the transportation distance, quantity and customer needs. For short-distance transportation and small batches of cables, road transportation is usually used, and trucks are used as transportation tools. The truck compartment needs to be clean, dry and free of sharp objects to prevent damage to the cable packaging and the cable itself. When loading cables, the cable reels should be placed stably in the compartment and fixed firmly with ropes or chains to avoid rolling and collision of the cable reels due to bumps, sudden braking, etc. during transportation. For long-distance transportation and large quantities of cables, railway transportation or water transportation can be chosen. Railway transportation has the characteristics of large transportation volume and good stability, and is suitable for long-distance and large-volume cargo transportation; water transportation has relatively low cost and is suitable for long-distance transportation across countries or regions, but the transportation time is relatively long.

During transportation, care must be taken to protect the cables from extreme weather. In hot weather, avoid long-term exposure of cables to sunlight to prevent PVC sheaths and XLPE insulation layers from aging and deformation due to high temperature; in cold weather, appropriate thermal insulation measures should be taken to prevent cables from becoming brittle due to low temperature and affecting their flexibility. In case of rain and snow, ensure that the rainproof facilities of the transport tools are in good condition to prevent the cables from getting damp.

During transportation, the cables should be avoided from severe impact and vibration. When loading and unloading cables, special lifting equipment such as cranes and forklifts should be used, and rough loading and unloading is strictly prohibited. When hoisting, select appropriate lifting points to ensure that the cable reel is evenly stressed, so as to avoid deformation of the cable reel or damage to the cable itself. During transportation, drivers should drive carefully, abide by traffic rules, avoid sudden acceleration, sudden braking and sharp turns, and reduce the shaking and collision of cables.

For internationally transported cables, it is also necessary to comply with the import and export regulations of relevant countries and regions, go through the necessary customs declaration procedures, and ensure the smooth progress of the transportation process. At the same time, it is necessary to consider the climatic conditions and transportation standards of different countries and regions, and take corresponding protective measures.

Transportation personnel need to be familiar with the characteristics and transportation requirements of the cables. Before transportation, they should check the packaging and fixing of the cables to ensure that they meet the transportation standards. During transportation, they should regularly check the condition of the cables, deal with problems in a timely manner, and ensure that the cables can be delivered to the destination safely and on time.
