I. From the Perspective of the Product Itself
(I) Specification Parameters
The specification parameters of 240mm² XLPE 4-core copper sheathed armoured cable (
Economical Power Cable) are important reflections of its performance and application scope, and each parameter is carefully designed and strictly controlled.
In terms of core specifications, the cable adopts a 4-core design, with each core having a cross-sectional area of 240mm². Such a core configuration can meet the needs of high-power power transmission. In medium and low voltage distribution systems, it can efficiently transmit electrical energy and ensure the stability of power supply. The 4-core design meets the requirements of three-phase four-wire circuits, where three cores are used to transmit three-phase current, and the other serves as a neutral wire, which plays a role in balancing current and stabilizing voltage to ensure the normal operation of the circuit.
In terms of voltage level, the cable is suitable for medium and low voltage distribution systems, and the specific voltage range complies with relevant industry standards. It can work safely and stably within the specified voltage range, providing reliable power support for various medium and low voltage electrical equipment and lines.
Insulation thickness is a key parameter to ensure the insulation performance of the cable. The XLPE insulation layer of the cable has a specific thickness, which is accurately calculated to effectively prevent current leakage, ensure the insulation reliability of the cable under normal working voltage, and also withstand certain overvoltage impacts.
The thickness of the copper sheath and the armoured layer is also clearly specified. The thickness of the copper sheath must not only ensure the realization of its sealing, moisture-proof and auxiliary conductive functions, but also consider economy; the thickness of the armoured layer needs to ensure that it has sufficient strength to resist external mechanical impacts, extrusion and other adverse factors, and protect the internal structure of the cable from damage.
In addition, the outer diameter and bending radius of the cable are also important specification parameters. The outer diameter of the cable will affect its laying method and installation space, while a reasonable bending radius ensures that the cable will not be damaged due to excessive bending during installation, and ensures that its electrical and mechanical properties are not affected.

(III) Material and Style
Material
The material selection of the cable is the basis for its excellent performance and economy. Each material is carefully selected to achieve a balance between performance and cost.
The conductor is made of high-purity electrolytic copper. Electrolytic copper has extremely high purity and excellent conductivity, which can minimize energy loss during current transmission and improve power transmission efficiency. At the same time, high-purity electrolytic copper has good ductility and toughness, which is easy to be processed into cores, and is not easy to break during installation and use, ensuring the service life of the cable.
The insulation layer is made of cross-linked polyethylene (XLPE), which has many advantages. It has excellent temperature resistance and can maintain stable insulation performance in the temperature range of -40℃ to 90℃, without aging, cracking and other problems due to drastic temperature changes. XLPE has excellent electrical insulation performance and high insulation resistance, which can effectively prevent current leakage and ensure the safe operation of the cable. In addition, it also has good chemical corrosion resistance and anti-aging performance, and can adapt to various complex environmental conditions, extending the service life of the cable.
The outer copper sheath is made of high-quality copper. Copper has good conductivity and sealing performance. The copper sheath can not only assist in conduction and improve the current-carrying capacity of the cable, but also play a role in sealing and moisture-proof, preventing moisture and dampness from entering the inside of the cable and affecting its insulation performance. At the same time, copper has strong corrosion resistance, which can protect the internal structure of the cable from external corrosion factors.
The armoured layer is made of high-strength metal materials. This material has high mechanical strength and hardness, and can effectively resist external mechanical impacts, extrusion and gnawing by rodents. The material selection of the armoured layer fully considers economy on the premise of ensuring protective performance, so that the cable has good protective ability while the cost is effectively controlled.
Style
In terms of appearance, the cable presents a regular and compact feature. The whole is a cylindrical structure, with
4 Cores arranged in order inside. The outside is wrapped with XLPE insulation layer, copper sheath and armoured layer in turn. All layers are closely combined to form a solid whole.
The color of the cable is usually dark colors such as black or gray. This color is not only resistant to dirt, but also can absorb heat, reducing the impact of direct sunlight on the cable. The colors of the cores are clearly distinguished, which is convenient for identification and connection during installation, improving installation efficiency.
The style design not only considers the functionality of the cable, ensuring that all parts of the structure can work together to exert the best performance, but also takes into account the convenience and aesthetics of installation, enabling it to adapt to different laying environments and installation methods.
(IV) Production Process
The production process of 240mm² XLPE 4-core copper sheathed armoured cable (economical power cable) is advanced and rigorous. While ensuring product quality, economy is achieved through optimized processes.
In the conductor manufacturing link, first, high-purity electrolytic copper is smelted to remove impurities, and then made into copper rods through continuous casting process. The copper rod is drawn into
Copper Wire with the required diameter through wire drawing treatment. During the wire drawing process, the drawing speed and die size need to be accurately controlled to ensure the uniform diameter of the copper wire. After that, multiple copper wires are stranded according to certain rules to form a 240mm² core. The stranding process can improve the
Flexibility and overall strength of the core, making it more convenient for subsequent processing and installation.
The insulation layer is made by cross-linking process. Polyethylene particles are added into the extruder, heated and melted, and then extruded and coated on the surface of the conductor through a die to form a preliminary insulation layer. Subsequently, the extruded insulation layer is cross-linked, usually by dry cross-linking, so that the polyethylene molecules change from linear structure to network structure. This cross-linking reaction can significantly improve the temperature resistance, mechanical strength and insulation performance of the insulation layer. At the same time, this process is relatively mature and has low cost, which is in line with the positioning of economical cables.
The copper sheath is made by continuous extrusion process. The copper strip is continuously wound and welded on the outside of the
Insulated Core through special equipment to form a tight copper sheath. Advanced welding technology is used during the welding process to ensure the quality of the weld and the sealing and conductivity of the copper sheath. This process has high production efficiency and can effectively control costs.
The armoured layer is made by winding high-strength metal strips around the outside of the copper sheath through an armouring machine at a certain angle and density to form the armoured layer. During the winding process, the tension of the metal strip and the winding pitch need to be strictly controlled to ensure the uniformity and tightness of the armoured layer, so that the armoured layer can give full play to its protective role. At the same time, by optimizing the winding parameters, production efficiency is improved and production costs are reduced.
Throughout the production process, quality inspection runs through. From the incoming inspection of raw materials, to the online inspection of each process, and then to the factory inspection of finished products, strict standards and advanced testing equipment are adopted. For example, the resistance of the conductor, the insulation resistance and voltage resistance performance of the insulation layer, the sealing performance of the copper sheath, the adhesion of the armoured layer, etc. are comprehensively tested to ensure that each batch of cables meets the relevant quality standards. At the same time, by optimizing the production process, reducing waste in the production process, improving production efficiency, and realizing the economy of the cable.
II. From the Perspective of General Product Information
(I) Packaging
The packaging design of 240mm² XLPE 4-core copper sheathed armoured cable (economical power cable) fully considers the product protection, transportation and storage needs, while taking into account economy.
For coiled cables, wooden reels are usually used for packaging. The wooden reel has sufficient strength and stability, which can bear the weight of the cable and prevent deformation or damage during transportation and storage. When the cable is wound on the reel, it will be wound according to a certain tension to ensure that the cable is arranged neatly and avoid mutual winding and extrusion. Baffles will be installed on both sides of the reel to prevent the cable from slipping off the reel. In order to reduce costs, on the premise of ensuring the protection effect, a moderately thick plastic film will be used to wrap the outer layer of the cable to play a moisture-proof and dust-proof role.
For small-length cables or samples, strong cartons are generally used for packaging. The material of the carton is selected to have certain strength and control costs. The size of the carton will be customized according to the length and diameter of the cable to ensure that the cable can be placed tightly in it to avoid shaking and collision during transportation. Inside the package, some low-cost buffer materials, such as waste newspapers and foam fragments, will be filled to reduce the impact of transportation on the cable.
The packaging surface will be marked with necessary product information, including product name, specification model, length, weight, manufacturer, production date, etc. This information is marked concisely and clearly, which is convenient for customers to check when receiving, and will not increase too much packaging cost.

For short-distance transportation, road transportation is usually adopted. Road transportation has high flexibility, can realize door-to-door service, and the transportation cost is relatively low, which is suitable for the transportation of small batches of cables. For long-distance transportation with large transportation volume, railway transportation will be selected. Railway transportation has the characteristics of large transportation volume, low cost and good stability, which can effectively reduce the cost of long-distance transportation.
During transportation, the cable needs to be properly fixed. For cables packaged with wooden reels, steel wire ropes or fastening belts will be used to firmly fix the reels in the carriage of the transport vehicle to prevent the reels from sliding and colliding due to vehicle bumps, turns and other reasons during transportation. The fixing method is simple and effective, which not only ensures the safety of the cable, but also does not increase too much transportation cost.
During transportation, attention should also be paid to protecting the cable from harsh environments. A tarpaulin is covered on the transport vehicle to prevent the cable from being exposed to direct sunlight, rain and snow. At the same time, reasonably arrange the transportation route and time, avoid bad weather and road sections with poor road conditions, and ensure the smooth progress of transportation.
Transport personnel need to understand the characteristics and transportation requirements of the cable, check the condition of the transport vehicle before transportation, and ensure that the vehicle is running normally.
