Detailed Introduction to 1c×10mm² Copper Stranded (Cu/XLPE/PVC) Cable (0.6/1kV)
I. From the Perspective of the Product Itself
(I) Specification Parameters
The core specification parameters of the 1c×10mm² copper stranded (Cu/XLPE/PVC) cable have clear and rigorous standards, which can accurately meet the power transmission needs under the 0.6/1kV voltage level.
In terms of conductor parameters, its cross-sectional area is 10mm², made of multiple strands of
Copper Wire stranded together. The diameter of a single copper wire is strictly controlled, usually between 0.1mm-0.3mm. Through a specific stranding process, multiple strands of copper wire are tightly combined, which not only ensures the
Flexibility of the conductor but also guarantees the overall conductivity. The use of high-purity copper (purity ≥99.9%) makes the DC resistance of the conductor ≤1.83Ω/km. This extremely low DC resistance means that energy loss is minimized during current transmission, greatly improving the efficiency of power transmission.
The parameters of the insulation layer are also crucial. The thickness of the cross-linked polyethylene (XLPE) insulation layer used is uniform, usually between 0.8mm-1.2mm. After special cross-linking treatment, XLPE forms a three-dimensional network molecular structure, making its insulation resistance ≥10¹⁴Ω·m, which can effectively isolate the conductor from the outside world and prevent electric leakage or breakdown. In terms of temperature resistance, the long-term working temperature can reach 90℃, and even in the case of a short circuit, the maximum temperature can reach 250℃, with the short-circuit duration not exceeding 5 seconds, fully ensuring the safety of the cable in abnormal situations.
The thickness of the outer polyvinyl chloride (PVC) sheath is generally between 1.0mm-1.5mm, with good mechanical strength. Its tensile strength is ≥12MPa, and the elongation at break is ≥150%, which can effectively resist external extrusion, friction, and collision. At the same time, the
PVC Sheath complies with the GB/T 18380 flame retardant standard, which can slow down the spread of flames in case of fire, buying valuable time for personnel evacuation and fire fighting.
The overall diameter of the cable varies according to different production processes and material ratios, usually between 6mm-8mm. The minimum bending radius is 6 times the outer diameter of the cable (static) and 12 times (dynamic). This parameter ensures that the cable can be flexibly bent in complex wiring environments to meet various installation needs. The rated voltage is 0.6/1kV, which is clearly suitable for power transmission and distribution in low-voltage power distribution systems. In terms of short-circuit withstand capacity, the cable can withstand a short-term overload of 25 times the rated current within 5 seconds, providing strong protection for the safety of the circuit in case of faults.
(II) Characteristic Uses
The 1c×10mm² copper stranded (Cu/XLPE/PVC) cable has irreplaceable characteristic uses in many fields due to its unique performance.
In the field of industrial power distribution, this cable plays an important role. For small motors, their normal operation requires a stable power supply. The current-carrying capacity of approximately 55A (when laid in air) brought by the 10mm² cross-sectional area of the cable can meet the power demand of small motors, ensuring that the motors will not shut down or malfunction due to insufficient power supply during production. The industrial control cabinet is the control core in industrial production, with complex internal circuits, and has high requirements for the flexibility and safety of the cable. The single-core design and good bending performance of the cable enable it to be flexibly routed inside the control cabinet. At the same time, the excellent performance of the XLPE insulation layer and PVC sheath ensures the stable operation of the control cabinet.
In terms of
Building Wiring, the floor distribution trunk line needs to efficiently distribute power from the main distribution box to each floor. The efficient conductivity and stable transmission capacity of the cable can ensure the balanced and stable power supply of each floor. The emergency lighting system is crucial in emergency situations. The reliability and weather resistance of the cable enable it to ensure the normal power supply of emergency lighting equipment even in emergency situations such as power outages, providing necessary lighting for personnel evacuation. The dedicated line for fire-fighting equipment has extremely high safety requirements for the cable. The flame-retardant characteristics of the PVC sheath and the overall insulation performance can ensure the power supply of fire-fighting equipment in dangerous situations such as fires, ensuring the normal operation of the fire-fighting system.
In equipment connection scenarios, the cable also performs well. In the connection between workshop equipment and distribution boxes, since the workshop environment may have oil stains, dust, etc., the XLPE insulation layer of the cable has strong chemical corrosion resistance, and the PVC sheath is wear-resistant, which can adapt to this complex environment and ensure stable power transmission between the equipment and the distribution box. The temporary construction power supply line needs to be moved and laid frequently. The flexible design and good mechanical properties of the cable make it not easy to be damaged during frequent movement and installation, meeting the power demand of temporary construction.
In addition, its single-core design is particularly suitable for occasions that require separate pipe threading. In places where pipe threading is needed for wiring in building walls, floors, etc., the single-
Core Cable can easily pass through the pipe, avoiding the difficulty in laying caused by the entanglement of core wires in
Multi-Core cables, and greatly improving the construction efficiency. For some areas that require flexible wiring, such as stage lighting equipment wiring, temporary power supply wiring in exhibition venues, etc., the flexibility and operability of the cable can also meet the needs well.
(III) Material and Style
Material
The conductor is made of high-purity copper with a purity of ≥99.9%. This high-purity copper has excellent conductivity and is an ideal material for power transmission. Copper itself has good ductility and toughness, which can be drawn into fine copper wires, and then formed into a conductor through a stranding process, which not only ensures the conductivity efficiency but also endows the conductor with good flexibility. At the same time, copper has high chemical stability, is not easy to be corroded in normal use environments, and can maintain good conductivity for a long time.
The insulation layer uses cross-linked polyethylene (XLPE), which is obtained by cross-linking ordinary polyethylene. Cross-linking treatment transforms the polyethylene molecules from a linear structure to a three-dimensional network structure, thereby greatly improving the performance of the material. Compared with ordinary polyethylene, XLPE has higher heat resistance, aging resistance, and mechanical strength. Its high-temperature resistance ensures that the cable can maintain stable insulation effect in a higher temperature environment, the aging resistance prolongs the service life of the cable, and the improvement of mechanical strength makes it not easy to be damaged when subjected to external forces.
The outer sheath is polyvinyl chloride (PVC), which is a commonly used polymer material with good mechanical properties and chemical stability. PVC material has a relatively low price and mature processing technology, and can form a uniform sheath layer through extrusion process. It has good impact resistance and wear resistance, which can effectively protect the internal insulation layer and conductor from external physical damage. At the same time, PVC has certain flame-retardant properties, and after special formula treatment, its flame-retardant effect is more significant, meeting relevant safety standards.
Style
In terms of appearance, the cable is cylindrical as a whole, with a smooth and flat surface. The color of the PVC sheath is usually black because black has good weather resistance, can absorb heat from sunlight, reduce the impact of temperature changes on the cable, and at the same time, black can better hide dust and stains, keeping the appearance of the cable clean.
The structural style of the cable is simple and reasonable. The single-core design makes the structure of the cable relatively simple, which is, from the inside out, the copper
Stranded Conductor, the XLPE insulation layer, and the PVC sheath. This structure has distinct layers, and each layer is closely combined to ensure the overall performance of the cable. The stranding method of the copper stranded conductor adopts regular stranding, that is, multiple strands of copper wire are stranded according to a certain stranding direction and pitch, making the structure of the conductor stable and flexible.
The XLPE insulation layer is evenly wrapped around the outside of the conductor, closely fitting with the conductor, without bubbles and gaps, ensuring the insulation effect. The PVC sheath is tightly wrapped around the outside of the insulation layer, forming a solid protective layer. The surface of the sheath is smooth, without burrs and protrusions, which is convenient for the laying and installation of the cable.
(IV) Production Process
The production process of the 1c×10mm² copper stranded (Cu/XLPE/PVC) cable is complex and rigorous, and each link is strictly controlled to ensure the quality of the product.
The first is the manufacturing process of the conductor. High-purity copper ingots are smelted and cast into copper rods. The quality of the copper rods directly affects the performance of the subsequent conductors. Therefore, parameters such as temperature and impurity content need to be strictly controlled during the smelting and casting process. Then, the copper rod is drawn into a copper wire of the required diameter through a wire drawing machine. During the wire drawing process, the drawing speed and the precision of the die must be controlled to ensure that the diameter of the copper wire is uniform and the surface is smooth. Next, multiple strands of copper wire are stranded according to a certain stranding scheme. During stranding, the tension of each strand of copper wire must be uniform, and the stranding direction and pitch must meet the design requirements to ensure the structural stability and flexibility of the conductor.
The extrusion process of the insulation layer is one of the key links. The stranded conductor is fed into the extruder, and at the same time, the XLPE material is heated and melted, then evenly wrapped around the outside of the conductor through the extrusion die to form the insulation layer. During the extrusion process, the extrusion temperature, extrusion speed, and die pressure must be strictly controlled to ensure that the thickness of the insulation layer is uniform and tightly combined with the conductor. The extruded insulation layer needs to undergo cross-linking treatment, usually by means of warm water cross-linking or steam cross-linking. The insulation layer is heated to a certain temperature and kept for a period of time to make the polyethylene molecules undergo a cross-linking reaction to form a three-dimensional network structure. Parameters such as temperature and time for cross-linking treatment need to be accurately controlled to ensure that the cross-linking degree meets the requirements.
The extrusion process of the sheath is similar to that of the insulation layer, but the material used is PVC. The conductor with the insulation layer after cross-linking treatment is fed into another extruder. The PVC material is heated and melted in the extruder, then wrapped around the outside of the insulation layer through the extrusion die to form the sheath. Similarly, the extrusion parameters must be controlled to ensure that the thickness of the sheath is uniform, the surface is smooth, and it is tightly combined with the insulation layer.
During the production process, multiple quality inspection procedures are also required. After the conductor is manufactured, its diameter, DC resistance and other parameters must be tested; after the insulation layer is extruded and cross-linked, the thickness, insulation resistance, temperature resistance and other properties of the insulation layer must be tested; after the sheath is extruded, the thickness, tensile strength, elongation at break, flame retardant performance and other properties of the sheath must be tested. In addition, the finished cable needs to undergo overall withstand voltage tests, bending tests, etc., to ensure that all performance indicators of the cable meet relevant standards.
Environmental control during production is also very important. The workshop needs to be kept clean and dry, and the temperature and humidity are controlled within appropriate ranges to avoid the impact of dust, moisture, etc. on product quality. At the same time, production equipment needs regular maintenance to ensure its normal operation, improve production efficiency and product quality.
II. From the Perspective of General Product Information
(I) Packaging
To ensure the quality of the 1c×10mm² copper stranded (Cu/XLPE/PVC) cable during transportation and storage, its packaging method is carefully designed.
For short-length cables (usually within 100 meters), plastic reels are used for packaging. The plastic reels are made of high-strength polyethylene material, which has certain pressure resistance and wear resistance. The cable is neatly wound on the reel, and appropriate tension is maintained during the winding process to avoid the cable from loosening. After winding, the entire reel and cable are tightly wrapped with plastic film, which has good moisture-proof and dust-proof performance and can effectively prevent the cable from being polluted and eroded by the external environment. The two ends of the reel are equipped with circular baffles, the diameter of which is larger than that of the reel, which can effectively prevent the cable from slipping off the reel.
For long-length cables (usually more than 100 meters), wooden cable reels are used for packaging. The wooden cable reels are made of high-quality hardwood, with a solid structure and can bear a large weight. The cable is tightly wound on the cable reel, and the number of layers and tension of the winding are strictly controlled to ensure that the cable will not loosen or deform during transportation. The outermost layer of the cable is also wrapped with a layer of plastic film to play a role in moisture-proof and dust-proof. The two sides of the wooden cable reel are equipped with metal flanges, and the flanges are provided with multiple holes, which are convenient for handling and loading/unloading with forklifts and other equipment. At the same time, a label is nailed on the wooden cable reel, which clearly indicates the model, specification, length, weight, manufacturer, production date and other information of the cable, facilitating users to identify and check.
Whether it is plastic reel or wooden cable reel packaging, obvious signs such as "Do not press heavily", "Moisture-proof", "Up" and other warning signs are printed on the outside of the packaging to remind transportation and storage personnel to pay attention to relevant matters and avoid damage to the cable due to improper operation.
(II) Transportation
The transportation of the 1c×10mm² copper stranded (Cu/XLPE/PVC) cable requires selecting an appropriate transportation method according to factors such as transportation distance and quantity, and taking corresponding protective measures.
Road transportation is one of the most commonly used transportation methods, suitable for short-distance and medium-distance transportation. The transport vehicles are closed trucks to prevent the cable from being exposed to direct sunlight, rain, and dust pollution. During loading, the packaged cables are neatly stacked in the carriage, and wooden boards or other buffer materials are placed between the cable reels to prevent damage caused by mutual collision. For wooden cable reels, steel wire ropes or fastening belts are used to firmly fix them in the carriage to ensure that they will not shake during transportation. During transportation, the driver should pay attention to controlling the speed, avoid sudden braking and sharp turns, and reduce the impact force on the cable.
Railway transportation is suitable for long-distance and large-volume cable transportation. Railway transportation has the advantages of large transportation volume, low cost, and good stability. Before transportation, the cable reels are placed in the designated position of the railway freight car and fixed firmly with special fixing devices to prevent displacement during transportation. At the same time, moisture-proof and dust-proof measures should be taken, such as covering the cable reels with waterproof cloth. The railway department will monitor the entire transportation process to ensure the safe transportation of goods.
Waterway transportation is mainly used for international trade or long-distance coastal transportation. The cables are transported by cargo ships. The cable reels are neatly placed in the cabin, avoiding stacking too high to prevent the bottom cable reels from being crushed and damaged. During transportation, attention should be paid to the ventilation and moisture-proof in the cabin to avoid damage to the cable due to moisture. At the same time, fixing measures should be taken to prevent the cable reels from moving due to 颠簸 during the ship's navigation.
No matter which transportation method is adopted, the cable should be avoided from severe collision, extrusion, and bending. During transportation, attention should be paid to the weather conditions at any time, and corresponding protective measures should be taken when encountering bad weather. Transport personnel should be familiar with the characteristics and transportation requirements of the cable to ensure that the cable is delivered to the destination safely and on time.
