This product series includes three specifications of flexible electric wires with polyvinyl chloride (PVC) insulation and copper cores: 2.5mm², 4mm², and 10mm². All adopt multi-strand stranded copper conductor design, featuring excellent flexibility and electrical conductivity, and are widely applicable to electrical wiring scenarios with different power requirements.​ The conductor is made of high-purity electrolytic copper through a fine stranding process, which not only reduces the rigidity of the wire, enabling it to easily cope with complex installation environments such as bending and folding, but also enhances the overall tensile resistance, capable of withstanding slight pulling and vibration in daily use. The number of conductor strands for the three specifications increases with the wire diameter, ensuring that while improving the current-carrying capacity, good softness is maintained to meet the flexible wiring needs of household, commercial and industrial places.​ The insulation layer is made of high-quality PVC material, with excellent insulation resistance, corrosion resistance and temperature resistance, and can work stably in an environment of -15℃ to 70℃. Its insulation thickness strictly follows industry standards. The average insulation thickness of 2.5mm² and 4mm² wires is not less than 0.8mm, and the insulation thickness of 10mm² wires is increased to more than 1.0mm due to higher current-carrying capacity, effectively blocking current leakage and ensuring electrical safety. In addition, the PVC insulation layer also has good anti-aging properties, extending the service life of the wire.​ In terms of performance parameters, the rated voltage of the three specifications is 300/500V, meeting the requirements of low-voltage power distribution systems. The current-carrying capacity increases with the wire diameter: 2.5mm² is suitable for high-power household appliances such as air conditioners and electric water heaters (continuous current-carrying capacity is about 25A); 4mm² can meet medium-power requirements such as small industrial equipment and commercial lighting circuits (about 32A); 10mm² is applicable to large current scenarios such as main distribution lines and large motor leads (about 57A), covering the full range of needs from daily household electricity use to industrial basic wiring.​ The product offers multiple color options such as red, blue, yellow, and green, facilitating the distinction between phase wires, neutral wires, and ground wires, and reducing the risk of construction misoperation. During the production process, strict quality inspections are carried out, including conductor resistance testing, insulation withstand voltage testing, low-temperature bending testing, etc., to ensure that each batch of products meets international safety standards.​ During installation, thanks to their soft characteristics, all three specifications of wires can easily pass through narrow spaces such as wall pipes and trunking, reducing construction difficulty. They are widely used in residential decoration, shopping mall wiring, factory equipment connection and other scenarios, not only meeting the stable power supply of small household appliances, but also supporting the efficient operation of industrial-grade equipment, making them an ideal electrical connection solution that combines safety and flexibility.
