(3) Material and Style
In terms of material selection and style design, Bya/Bym 1.5-16mm² PVC insulated copper wire fully meets EU standards and the needs of different usage scenarios.
The conductor is made of high-purity electrolytic copper with a purity of more than 99.95%. High-purity electrolytic copper has excellent conductivity, which can effectively reduce energy loss during current transmission, improve power transmission efficiency, and meet the EU requirements for energy conservation. At the same time, electrolytic copper has good ductility and toughness, so that the hard wire is not easy to break during bending and installation, and the multi-strand copper wire stranded structure of the flexible wire can also maintain good flexibility and mechanical properties.
The insulation layer is made of high-quality polyvinyl chloride (PVC) material, which has good insulation performance, can effectively insulate current, prevent electric leakage accidents, and meet the strict EU standards for electrical safety. The PVC insulation layer also has good temperature resistance, and can maintain stable performance in the temperature range of -30°C to 70°C, adapting to different climatic conditions in EU regions. In addition, it can resist moisture, dust and general chemical corrosion, prolonging the service life of the cable.
In terms of style, there are two types: hard wire and flexible wire. The hard wire has a solid single-core structure, which makes it have high mechanical strength, not easy to be stretched or broken, and suitable for use in fixed wiring scenarios, such as wall pipe threading and bridge laying. Its wire body is straight, easy to cut and install, and can ensure neat and standardized wiring.
The flexible wire has a multi-strand stranded structure, composed of multiple fine copper wires stranded together. This structure makes the flexible wire have strong flexibility, easy to bend and fold, and suitable for use in scenarios that require frequent movement or bending, such as power cords of household appliances and connecting wires of portable equipment. The flexible wire is not easy to be damaged during bending and can adapt to various complex installation environments.
The colors of the cables are also clearly distinguished. According to EU standards, the live wire is usually brown, black or gray, the neutral wire is blue, and the
Ground Wire is yellow-green 双色. The design of different colors is convenient for installers to quickly identify wires for different purposes during wiring, reducing wiring errors and improving installation efficiency and safety.
(4) Production Process
The production process of Bya/Bym 1.5-16mm² PVC insulated copper wire strictly follows EU standards, and every link from raw material processing to finished product inspection is 精益求精.
In the conductor manufacturing link, for hard wires, high-purity electrolytic copper is melted and made into copper rods through a continuous casting process, and then the copper rods are drawn into solid single-
Core Copper wires of the required diameter through multiple wire drawing processes. 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 ensure good conductivity.
For flexible wires, copper rods are also made first, then the copper rods are drawn into multiple fine copper wires, and then these fine copper wires are stranded together according to a specific stranding method and pitch to form a multi-strand
Stranded Conductor. During the stranding process, the tension is strictly controlled to ensure that each strand of copper wire is evenly stressed and tightly stranded, so as to ensure the overall performance and flexibility of the conductor.
The extrusion of the insulation layer is one of the key processes. A special extruder is used to heat the PVC material to a molten state, and then evenly coat it on the surface of the conductor 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 cables to meet the requirements of EU standards for insulation performance. After extrusion, the insulation layer is quickly cooled and shaped through a cooling water tank to ensure its dimensional stability and structural integrity.
During the production process, the cable also needs to 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 the insulation layer, insulation resistance test, voltage resistance test, temperature resistance test, mechanical performance test, etc. are carried out to verify its insulation effect, stability and durability. In addition, the appearance of the cable is strictly inspected to ensure that the surface is smooth, the color is uniform, and there are no defects such as damage.
The finished cables also need to undergo various tests related to CE certification, including electrical safety, mechanical performance, aging resistance, environmental protection, etc. Only products that meet all requirements can leave the factory for sale, ensuring safe and reliable products for electrical wiring in EU regions.
