Cross-sectional Size: The cross-sectional size of this series of cables ranges from 1.5mm² to 16mm². This range is set based on in-depth research and analysis of different electrical scenarios. The 1.5mm² cable has a relatively small diameter, which can efficiently transmit electricity in low-power scenarios such as household lighting circuits without causing material waste; while the 16mm² cable has a larger diameter, which can meet the power transmission needs of larger power such as residential incoming lines and small industrial equipment. Cables with different cross-sectional sizes also have obvious differences in appearance. The larger the cross-section, the thicker the outer diameter of the cable, and you can clearly feel the difference in size when holding it in your hand.
Voltage Level: The designed voltage level is 450/750V, among which 450V is suitable for fixed laying scenarios with an AC rated voltage of 450V and below, and 750V is suitable for connection of mobile or semi-mobile equipment below 750V. This voltage level is determined based on industry standards for low-voltage distribution systems and the voltage requirements of common electrical equipment, which can be compatible with most low-voltage electrical scenarios and ensure the safety and stability of power transmission.
Current-Carrying Capacity: Current-carrying capacity is one of the important parameters of cables, and there are obvious differences in current-carrying capacity between cables of different cross-sections. Generally speaking, the current-carrying capacity of a 1.5mm² cable is about 10-16A, which can meet the electricity demand of household lighting and small household appliances (such as table lamps, chargers, etc.); the current-carrying capacity of a 2.5mm² cable is about 16-25A, suitable for ordinary socket circuits; the current-carrying capacity of a 4mm² cable is about 25-32A, which can be used for high-power household appliances such as air conditioners and electric water heaters; the current-carrying capacity of a 6mm² cable is about 32-40A, which can meet the needs of higher-power equipment; the current-carrying capacity of a 10mm² cable is about 40-60A, which is mostly used for residential incoming lines or branch lines of small industrial equipment; the current-carrying capacity of a 16mm² cable is about 60-80A, suitable for main distribution lines in commercial places, etc. These current-carrying capacity data are measured under standard environmental conditions (such as temperature 30℃, good ventilation, etc.). In actual use, if the ambient temperature is too high or the heat dissipation conditions are not good, the current-carrying capacity will decrease.
Conductor Structure: The core conductor is made of high-purity electrolytic copper with a purity of more than 99.95%. The conductor structure is multi-strand twisted, which not only improves the Flexibility of the cable, facilitates laying and installation, but also reduces the skin effect and improves the conductivity efficiency. Cables with different cross-sections have different numbers of strands and single-strand diameters. For example, a 1.5mm² cable may be composed of multiple strands of Copper Wires with a diameter of about 0.15mm, while a 16mm² cable is composed of more strands of thicker copper wires.
Insulation Layer Parameters: The insulation layer is made of polyvinyl chloride (PVC) material, and its thickness varies according to the cross-sectional size, generally between 0.6-1.2mm. The uniformity of the thickness of the insulation layer is the key to ensuring the insulation performance of the cable, which is strictly controlled within the relevant standard range to ensure that it can effectively isolate the conductor from the external environment. At the same time, the withstand voltage strength of the insulation layer has also been strictly tested, and no breakdown will occur under the rated voltage.
Household Electricity Scenarios:
1.5mm² Cable: Mainly used in household lighting circuits, including power supply for lamps in living rooms, bedrooms, kitchens and other areas. Since the power of lighting fixtures is relatively small, the current-carrying capacity of the 1.5mm² cable can fully meet the demand, and its thin diameter is convenient for pipe laying in walls or ceilings.
2.5mm² Cable: Suitable for ordinary socket circuits in homes, such as TV sockets, computer sockets, small household appliance sockets, etc. The power of the equipment connected to these sockets is moderate, and the 2.5mm² cable can supply power to them stably.
4mm² to 6mm² Cables: Used to connect high-power household appliances such as air conditioners, electric water heaters, and microwave ovens. These devices have large currents during operation and require cables with large current-carrying capacity to ensure the safety of power transmission and avoid safety accidents such as fires caused by cable overload.
10mm² to 16mm² Cables: As residential incoming lines, they undertake the important task of introducing external power into the internal distribution system of the home, and need to have a large current-carrying capacity to meet the electricity demand of the entire home.
Industrial Electricity Scenarios:
10mm² to 16mm² Cables: Widely used in small industrial equipment, such as small machine tools, blowers, water pumps, etc. These devices have relatively large power and require stable power supply, and cables of this specification can meet their power transmission needs.
4mm² to 6mm² Cables: Can be used for power supply of auxiliary equipment in industrial workshops, such as lighting fixtures and small electric tools.
Commercial Electricity Scenarios:
10mm² to 16mm² Cables: Often used in main distribution lines of commercial places, such as total distribution lines of shopping malls, supermarkets, office buildings, etc., to distribute power to distribution boxes in various areas.
4mm² to 6mm² Cables: Used for power supply lines of equipment such as air conditioners, elevators, and billboards in commercial places.
1.5mm² to 2.5mm² Cables: Suitable for lighting circuits and ordinary socket circuits in commercial places, such as lighting and computer sockets in offices.
Connection of Mobile or Semi-mobile Equipment: In the connection of mobile or semi-mobile equipment below 750V, such as small electric tools and temporary power supply lines, the flexibility and pliability of this series of cables can meet basic usage needs, facilitating the movement and operation of the equipment.
Conductor Material: High-purity electrolytic copper is used, which has excellent electrical conductivity, and its conductivity is close to that of internationally standard pure copper. High-purity copper can reduce the resistance during current transmission, thereby reducing energy loss and improving power transmission efficiency. At the same time, electrolytic copper has good ductility and toughness, which is convenient for processing into a multi-strand twisted conductor structure, and is not easy to break during use.
Insulation Layer Material: Polyvinyl chloride (PVC) is the main material of the insulation layer, which has the following characteristics:
Good Electrical Insulation Performance: It can effectively prevent current leakage, ensure that the insulation resistance of the cable meets the standard requirements, and prevent faults such as short circuits.
Chemical Corrosion Resistance: It has a certain resistance to chemicals such as acids, alkalis, and salts, and can maintain stable performance in some corrosive environments.
High Mechanical Strength: It has certain resistance to stretching, extrusion, and wear, and can withstand mechanical stress during laying and use.
Certain Flame Retardancy: When exposed to open fire, it is not easy to burn quickly, and the smoke and toxic gases generated during combustion are relatively few, which can delay the spread of fire and gain time for personnel evacuation and fire fighting.
Style: This series of cables are all round cables, and this style has many advantages in the production, laying, and installation processes. The circular structure makes the thickness of the cable's insulation layer uniform, ensuring consistent insulation performance in all directions; when laying through pipes, the circular cable has less resistance, which is convenient for construction; at the same time, the circular style is also convenient for winding and storing the cable.
Conductor Manufacturing: First, high-purity electrolytic copper is smelted, and then the copper ingot is drawn into copper wires of different diameters through a wire drawing machine. During the wire drawing process, it is necessary to strictly control the drawing speed and temperature to ensure that the diameter of the copper wire is uniform and the surface is smooth. After that, multiple strands of copper wires are twisted according to a certain twisting method. During the twisting process, the tension between the strands must be uniform to improve the overall performance of the conductor.
Insulation Layer Extrusion: The extrusion molding process is used to wrap the PVC Insulation layer around the conductor. First, the PVC particles are heated and melted, and then the molten PVC material is evenly wrapped around the surface of the conductor through the die of the extruder. During the extrusion process, it is necessary to accurately control the extrusion temperature, speed, and pressure to ensure that the thickness of the insulation layer is uniform, the surface is smooth, and it is closely combined with the conductor without defects such as bubbles and wrinkles.
Cooling and Solidification: The cable after extruding the insulation layer enters the cooling water tank for cooling, so that the PVC insulation layer can be quickly solidified and formed. During the cooling process, the control of water temperature is very important. If the water temperature is too high, it will cause the insulation layer to solidify slowly, affecting production efficiency; if the water temperature is too low, it may cause internal stress in the insulation layer, affecting its performance.
Inspection: During the production process, the cable undergoes multiple inspection procedures. Including the detection of parameters such as conductor diameter, insulation layer thickness, insulation resistance, and withstand voltage strength, to ensure that each batch of cables meets relevant standards and quality requirements. For unqualified products, rework or scrapping is carried out in a timely manner.
Printing: Information such as product model, specification, voltage level, and manufacturer is printed on the surface of the cable's insulation layer for easy identification and traceability by users. Special printers are used for printing to ensure that the handwriting is clear, firm, and not easy to fall off.
Packaging Materials: Plastic reels or wooden reels are used as the packaging carriers for cables. The appropriate specifications of reels or bobbins are selected according to the length and cross-sectional size of the cables. For shorter cables (such as less than 100 meters), plastic reels are usually used for packaging, which are lightweight and low-cost; for longer cables (such as 500 meters, 1000 meters, etc.), wooden reels are used for packaging, which can better bear the weight of the cables and prevent deformation during transportation and storage.
Packaging Method: The cable is neatly wound on the reel or bobbin. During the winding process, the tension of the cable must be uniform to avoid twisting and knotting. After winding, the reel or bobbin is wrapped tightly with plastic film or woven bag to prevent the cable from being damaged by dust, moisture, and mechanical damage during transportation and storage. At the same time, the packaging is marked with product model, specification, length, weight, production batch number, production date and other information.
Packaging Markings: In addition to the above product information, the packaging is also marked with some warning signs, such as "Do Not Press", "Moisture-proof", "Sun-proof", etc., to remind transportation and storage personnel to pay attention to relevant matters.
Transportation Methods: According to the order quantity, delivery location, and customer requirements, select appropriate transportation methods, including road transportation, railway transportation, waterway transportation, and air transportation. For short-distance domestic transportation, road transportation is usually used, which has the characteristics of high flexibility and fast delivery speed; for long-distance transportation or large quantities of goods, railway transportation or waterway transportation can be chosen, with relatively low cost; for emergency orders, air transportation can be used to quickly deliver the goods to customers.
Transportation Precautions:
During transportation, avoid severe impact, extrusion, exposure to sunlight and rain on the cables. When loading goods, the cable reels or bobbins should be fixed firmly to prevent rolling and collision during transportation.
For cables packaged with wooden reels, attention should be paid to preventing the reels from getting damp and mildewed, which will affect the quality of the cables. During transportation, measures such as covering with waterproof cloth can be taken.
