Details of 0.6/1kV 4×6mm², 4×10mm², 4×16mm² Steel Wire Armoured (SWA) Power Cables
I. From the Perspective of the Product Itself
(I) Specification Parameters
The 0.6/1kV 4×6mm², 4×10mm², 4×16mm² steel wire armoured (SWA)
Power Cables have clear and detailed settings in terms of specification parameters, which are the basis for their adaptation to different scenarios and meeting various needs.
In terms of voltage level, this series of cables is clearly applicable to the voltage range from 0.6kV to 1kV. This range makes it an ideal choice in low-voltage distribution systems, capable of stably transmitting electricity in three-phase four-wire circuits and providing reliable support for various low-voltage electrical equipment.
The number of cores and core cross-sectional area are important distinguishing parameters of this series of cables. All three specifications adopt a 4-core design, which is suitable for the needs of three-phase four-wire circuits. Among them, three cores are used to transmit three-phase current, and the other is used as a neutral wire, which plays the role of balancing current and stabilizing voltage. The core cross-sectional areas are 6mm², 10mm², and 16mm² respectively. Different cross-sectional areas determine the current-carrying capacity of the cable. The 6mm² cable is suitable for small-power equipment and lines, such as the centralized power supply lines of some small household appliances; the 10mm² cable has a moderate current-carrying capacity and can be used for medium-power industrial equipment or power distribution in small factories; the 16mm² cable can carry larger current and is suitable for high-power equipment and main power distribution lines in large buildings.
In addition to the above core parameters, the outer diameter of the cable also varies with the cross-sectional area of the core. The 6mm² cable has a relatively small outer diameter, which saves space during installation and is suitable for laying in narrow pipelines or spaces; the outer diameters of 10mm² and 16mm² cables increase in turn, and their size factors need to be considered when choosing the laying path and installation method. At the same time, the bending radius of this series of cables is also strictly regulated, generally not less than a certain multiple of the cable outer diameter, to ensure that during installation, the cable will not damage the internal structure due to excessive bending, and to ensure that its electrical and mechanical properties are not affected.
The 0.6/1kV 4×6mm², 4×10mm², 4×16mm² steel wire armoured (SWA) power cables show distinct characteristic uses in many fields by virtue of their unique performance.
In the field of building power distribution, cables of different specifications perform their respective duties. The 6mm² cable is often used in branch lines inside residences to supply power to lamps, small household appliances, etc. in families. Its small cross-sectional area and flexible installation characteristics can well adapt to the complex wiring environment in residences. The 10mm² cable is suitable for the main power distribution lines of residences and the power distribution systems of small commercial buildings, such as small supermarkets and convenience stores, and can meet the centralized power supply needs of multiple areas. The 16mm² cable plays an important role in the main power distribution lines of large residential quarters, office buildings and other buildings, and can carry the power load of the entire building or multiple floors.
In industrial plants, this series of cables is also widely used. For some small processing equipment and auxiliary equipment of assembly lines, the 6mm² cable can provide stable power support; the 10mm² cable can be used for medium-power production equipment, such as some small machine tools and blowers; the 16mm² cable is suitable for high-power industrial equipment, such as large compressors and motors, to ensure uninterrupted power supply during the operation of these equipment.
In terms of municipal engineering, this series of cables is also indispensable. In the street lamp system of urban roads, 6mm² or 10mm² cables can be selected for laying according to the power and spacing of street lamps. Their armoured layers can resist various environmental disturbances outdoors and ensure the normal lighting of street lamps. In the power distribution lines of public places such as parks and squares, this series of cables can also adapt to the outdoor natural environment such as wind, sun and rain by virtue of their good protection performance.
Outdoor lighting scenarios have high requirements for the protection performance of cables. The galvanized steel wire armoured layer of this series of cables enables them to work stably in outdoor environments. Whether it is the power supply lines of garden lamps, landscape lamps or traffic signal lamps, selecting the appropriate specification of this series of cables can ensure the continuous operation of lighting equipment and provide safety guarantee for travel and activities at night.
(III) Material and Style
Material
The material selection of this series of cables is the key to their excellent performance. Each material has been carefully selected to ensure the reliability and durability of the cables.
The conductor is made of high-purity copper. As an excellent conductive material, copper has extremely low resistivity, which can efficiently transmit electricity and reduce the loss of current during transmission. High-purity copper can also ensure the chemical stability of the conductor, which is not easy to be corroded, thus prolonging the service life of the cable. At the same time, copper has good ductility and toughness, making the conductor not easy to break during processing and installation, and easy to be made into the required core shape.
The insulation layer is made of cross-linked polyethylene (XLPE), which has many advantages. It has a wide temperature resistance range and can maintain stable insulation performance in the environment of -40℃ to 90℃, without aging, cracking and other problems due to drastic temperature changes. XLPE has 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, which can resist the erosion of harmful substances in the air and corrosive components in the soil on the insulation layer.
The outer armour is galvanized steel wire. The galvanizing treatment forms a dense protective film on the surface of the steel wire, which can effectively prevent the steel wire from being oxidized and corroded, and greatly improve the corrosion resistance and service life of the armour layer. The steel wire itself has high strength and hardness, and the braided armour layer forms a solid protective barrier, which can resist external mechanical impact, extrusion and gnawing by rodents, and provide reliable protection for the inner core and insulation layer of the cable.
Style
In terms of appearance, this series of cables presents a regular and compact feature. Cables of all three specifications are cylindrical, with cores arranged in order inside and stable structure. The outer galvanized steel wire armoured layer evenly wraps around the outside of the cable, forming a solid shell, which not only plays a protective role, but also makes the cable have certain rigidity, facilitating laying and fixing during installation.
Cables of different specifications differ in thickness. The 6mm² cable is relatively thin, appearing more slender and flexible; the 10mm² and 16mm² cables become thicker in turn, and their rigidity also increases slightly. This style design not only considers the functionality of the cable, ensures the stability and cooperative work of various parts of the structure, but also takes into account the convenience of installation, enabling it to adapt to different laying environments and installation methods.
(IV) Production Process
The production process of 0.6/1kV 4×6mm², 4×10mm², 4×16mm² steel wire armoured (SWA) power cables adopts a series of advanced and rigorous production processes to ensure that the product quality meets relevant standards and requirements.
In the conductor manufacturing link, first, high-purity copper raw materials are 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 core with the required cross-sectional area. 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 or warm water 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, ensuring that the insulation layer can work stably in various environments.
Core stranding is to strand four cores (three phase wires and one neutral wire) according to a certain pitch. During the stranding process, it is necessary to ensure the stable relative position between the cores to avoid mutual friction and extrusion. The outside of the
Stranded Core will be wrapped with an inner lining layer, which is usually made of polyvinyl chloride or polyethylene material, playing a role of buffering and protection, and also providing a smooth surface for the subsequent armouring process.
The production of the armour layer is one of the key processes in the production of this series of cables. Galvanized steel wires are wound around the outside of the inner lining layer through an armouring machine according to a certain angle and density to form the armour layer. During the winding process, the tension of the steel wire and the winding pitch need to be strictly controlled to ensure the uniformity and tightness of the armour layer, so that the armour layer can give full play to its protective role. After the armouring is completed, an outer sheath is extruded and coated on the outside of the armour layer. The outer sheath is made of weather-resistant polyvinyl chloride material, which further enhances the corrosion resistance and mechanical protection performance of the cable.
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 adhesion of the armour layer, etc. are comprehensively tested to ensure that each batch of cables meets the relevant quality standards.
II. From the Perspective of General Product Information
(I) Packaging
The packaging design of 0.6/1kV 4×6mm², 4×10mm², 4×16mm² steel wire armoured (SWA) power cables fully considers the product protection, transportation and storage needs, and adopts a scientific and reasonable packaging method.
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. At the same time, the outer layer of the cable will be wrapped with a moisture-proof and dust-proof plastic film to protect the cable from pollution and moisture erosion from the external environment.
For small-length cables or samples, strong cartons or wooden boxes are generally used for packaging. The size of the carton or wooden box 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 buffer materials, such as foam boards and bubble films, will be filled to further reduce the impact of transportation on the cable.
Whether it is wooden reel packaging, carton or wooden box packaging, detailed product information will be marked on the packaging surface, including product name, specification model, length, weight, manufacturer, production date, implementation standard, etc. This information is not only convenient for customers to check when receiving products, but also conducive to product traceability and management.
(II) Transportation
The transportation process of this series of cables needs to strictly abide by relevant regulations and requirements to ensure that the products can be delivered to the destination safely and timely.
In terms of transportation mode selection, reasonable arrangements will be made according to the transportation distance, transportation volume and customer needs. For short-distance transportation, road transportation is usually adopted. Road transportation has the characteristics of high flexibility and door-to-door service, and is suitable for small-batch and multi-batch cable transportation. For long-distance transportation, railway transportation or long-distance road transportation can be selected. Railway transportation has the advantages of large transportation volume, relatively low cost and good stability, and is suitable for long-distance transportation of large quantities of cables; long-distance road transportation can better meet the customer's requirements for transportation time.
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 颠簸，turning and other reasons during transportation. For cables packaged in cartons or wooden boxes, they will be neatly stacked in the carriage and fixed with partitions or ropes to avoid mutual extrusion and collision.
During transportation, attention should also be paid to protecting the cable from harsh environments. A tarpaulin should be covered on the transport vehicle to prevent the cable from being exposed to direct sunlight, rain, snow and ice. At the same time, it is necessary to avoid mixing the cable with corrosive substances and sharp objects to prevent the cable from being corroded or mechanically damaged.
Transport personnel need to have relevant professional knowledge and experience, and understand the characteristics and transportation requirements of cables. Before transportation, the condition of the transport vehicle should be checked to ensure that the braking, suspension and other systems of the vehicle are normal. During transportation, the fixing of the cable and the integrity of the package should be checked regularly, and problems should be handled in time.
