Detailed Introduction to 2.5mm²-6mm² PVC Insulated Solid Copper Wire Set
I. From the Perspective of the Product Itself
(1) Specification Parameters
The specification parameters of the 2.5mm²-6mm² PVC insulated
Solid Copper Wire set are carefully designed, fully considering the power demand of household heating systems, and providing a solid guarantee for their stable operation.
This set includes solid copper wires of three common specifications: 2.5mm², 4mm², and 6mm². For the 2.5mm² copper wire, its conductor diameter is approximately 1.78mm, the conductor DC resistance at room temperature does not exceed 8.21Ω/km, and the safe current-carrying capacity is about 25A in air and 30A in soil, which is suitable for heating equipment with relatively low power. The 4mm² copper wire has a conductor diameter of about 2.25mm, a conductor DC resistance at room temperature of no more than 5.01Ω/km, and a safe current-carrying capacity of approximately 32A in air and 40A in soil, which can meet the power demand of medium-power heating equipment. The 6mm² copper wire has a conductor diameter of about 2.76mm, a conductor DC resistance at room temperature of no more than 3.30Ω/km, and a safe current-carrying capacity of about 42A in air and 50A in soil, which can cope with the power transmission of high-power heating equipment.
All specifications of copper wires have a rated voltage of 600V, which matches the voltage of the household low-voltage distribution network and can be directly connected to the household circuit system without additional voltage conversion devices, simplifying the installation process. The temperature resistance level of the insulation layer is 70°C. This parameter ensures that in the environment where the temperature around the household heating system rises, the insulation layer can maintain stable performance, and will not have problems such as aging and cracking due to excessive temperature, effectively ensuring the insulation effect and service life of the wire.
In addition, each specification of copper wire in this set has a variety of length options, commonly 50 meters, 100 meters, 200 meters, etc., to meet the wiring length requirements of different household heating systems. The thickness of the insulation layer of the wire also strictly follows relevant standards. The insulation layer thickness of 2.5mm² copper wire is not less than 0.8mm, and the insulation layer thickness of 4mm² and 6mm² copper wires is not less than 1.0mm, ensuring good insulation performance.
(2) Characteristic Applications
The 2.5mm²-6mm² PVC insulated solid
Copper Wire Set, with its various specifications and stable performance, has a wide range of characteristic applications in household heating systems, which can meet the power connection needs of different heating equipment.
The 2.5mm² copper wire is suitable for low-power wall-mounted radiators. The power of such radiators is usually below 2000W. The current-carrying capacity of 2.5mm² copper wire can fully meet its power transmission needs, and its relatively thin wire diameter is convenient for wiring in the narrow space of the wall, making installation more convenient and flexible. At the same time, because the installation position of the wall-mounted radiator is relatively fixed, the requirement for the mechanical strength of the wire is moderate, and the 2.5mm² copper wire with a solid structure can be well adapted.
The 4mm² copper wire can match medium-power floor heating manifolds. The floor heating manifold needs to provide power control for multiple floor heating circuits at the same time, and its power is generally between 2000W-3500W. The current-carrying capacity of 4mm² copper wire can stably carry the current transmission within this power range. The wiring of the floor heating system is mostly under the floor, and the environment is relatively complex. The 4mm² copper wire has good mechanical strength and insulation performance, which can resist the extrusion and friction that may occur during floor installation and use, ensuring stable power transmission.
The 6mm² copper wire is mainly used to meet the power demand of high-power wall-hung boilers and other equipment. The power of wall-hung boilers is usually above 3500W, which has high requirements for power transmission. The large current-carrying capacity of 6mm² copper wire can ensure the power supply during its normal operation. The wall-hung boiler will generate a certain amount of heat during operation, and the surrounding environment temperature is relatively high. The insulation layer of 6mm² copper wire can withstand a temperature of 70°C, which can maintain stable performance in such an environment and ensure electrical safety.
In addition to the above main applications, the copper wires of this set can also be used for power connection of auxiliary equipment such as thermostats and circulation pumps in household heating systems. Different specifications of copper wires are reasonably matched according to the power of auxiliary equipment to ensure that the power transmission of the entire heating system forms a complete and stable network.
(3) Material and Style
In terms of material selection and style design, the 2.5mm²-6mm² PVC insulated solid copper wire set is fully combined with the use environment and needs of household heating systems, focusing on safety, durability and practicality.
The
Conductor Material is high-purity electrolytic copper with a purity of more than 99.95%. High-purity copper has excellent conductivity, which can effectively reduce energy loss during current transmission, improve the energy utilization efficiency of the heating system, and reduce the household electricity cost. At the same time, electrolytic copper has good ductility and toughness, so that the solid copper wire is not easy to break during bending and installation, ensuring the mechanical strength of the wire and being able to adapt to the complex wiring environment of the family.
The insulation layer is made of high-quality polyvinyl chloride (PVC) material. PVC material has good insulation performance, which can effectively isolate current, prevent electric leakage accidents, and ensure household electricity safety. It also has certain chemical corrosion resistance, which can resist the erosion of some chemical substances that may be encountered in the family environment, and prolong the service life of the wire. In addition, the
PVC Insulation layer has been specially treated to have good anti-aging performance, which is not easy to harden and crack during long-term use, and can always maintain a good insulation effect.
In terms of style, the copper wires of this set are all single-core solid structures. The single-core design makes the structure of the wire simple, which is more convenient for wiring, especially in operations such as wall penetration and pipe penetration, there will be no winding problems that may occur with
Multi-Core wires. Compared with the multi-strand stranded structure, the solid structure has higher mechanical strength, is not easy to be damaged when subjected to external extrusion and pulling, and is suitable for use in household concealed wiring, such as inside walls and under floors.
The colors of the wires are also clearly distinguished. Usually, the live wire is red, the phase wire is blue or black, and the
Ground Wire is yellow-green 双色. This color design is convenient for installers to distinguish wires for different purposes during wiring, reduces the occurrence of wiring errors, and improves the safety and efficiency of installation.
(4) Production Process
The production process of the 2.5mm²-6mm² PVC insulated solid copper wire set is rigorous and meticulous. Every link from raw material processing to finished product inspection is strictly controlled to ensure that the product quality meets relevant standards and household use requirements.
In the conductor manufacturing link, first, high-purity electrolytic copper is melted, and then made into copper rods through continuous casting process. The quality of the copper rod directly affects the performance of the subsequent copper wire. Therefore, during the casting process, parameters such as casting temperature and cooling rate are strictly controlled to ensure that the purity and mechanical properties of the copper rod meet the standards. Then, the copper rod is drawn through a wire drawing machine for multiple passes to draw the copper rod into a solid copper wire with the required diameter. During the wire drawing process, the size of the wire drawing die and the wire drawing speed are precisely controlled to ensure that the diameter of the copper wire is uniform, the surface is smooth and free of burrs, so as to reduce the resistance during current transmission.
The extrusion of the insulation layer is a key step in the production process. A special extruder is used to heat the PVC material to a molten state, and then evenly coat it on the surface of the solid copper wire to form an insulation layer. During the extrusion process, the extrusion temperature, pressure and speed are strictly controlled to ensure that the thickness of the insulation layer is uniform, closely combined with the conductor, and free of bubbles, pinholes and other defects. The thickness of the insulation layer is accurately adjusted according to different specifications of copper wires to meet the requirements of relevant standards for insulation performance. After extrusion, the insulation layer needs to be quickly cooled and shaped through a cooling water tank to ensure its dimensional stability and structural integrity.
During the production process, the copper wire will also undergo a number of performance tests. In terms of conductors, parameters such as DC resistance and diameter deviation are tested to ensure that the conductivity meets the standards. In terms of insulation layer, insulation resistance test, voltage resistance test, temperature resistance test, etc. are carried out to verify its insulation effect and stability. In addition, the appearance of the wire will be inspected to ensure that the surface is smooth, the color is uniform, and there are no defects such as damage.
In order to ensure the quality stability of the product, full-process quality monitoring is implemented during the production process, and each production link has detailed records for traceability. After production, the finished wires will be sampled and tested according to certain batches. Only products that pass all testing items can leave the factory for sale, providing reliable wire products for the safe operation of household heating systems.
