This product is a solid copper core polyvinyl chloride (PVC) insulated wire, available in two specifications: 1×1.5mm² and 1×2.5mm². The core conductor is made of high-purity solid copper, which boasts excellent electrical conductivity and mechanical strength. It can effectively reduce energy loss during current transmission, ensuring the stability and safety of power transmission. The surface of the copper core has undergone special treatment to enhance its oxidation resistance, prolonging the service life of the wire and making it suitable for long-term use in electrical environments. The insulation layer is made of polyvinyl chloride (PVC) material, which has good insulation properties, corrosion resistance, and flame retardancy. It can reliably isolate the conductor from the external environment, preventing potential safety hazards such as electric leakage and short circuits. The PVC insulation layer is tough and wear-resistant, adaptable to various installation scenarios, including indoor wiring, wall embedding, and pipe threading. It also has a certain temperature resistance, maintaining stable physical and chemical properties under normal ambient temperatures. Both specifications of the wire meet the voltage rating requirement of 300/500V, where "300V" refers to the rated voltage when the wire is insulated from the ground, and "500V" refers to the rated voltage for line-to-line operation. They are suitable for low-voltage power distribution systems and widely used in lighting, power equipment connection, and daily electrical wiring in residential buildings, commercial structures, small industrial facilities, and other places. The product strictly complies with IEC 60227 standard formulated by the International Electrotechnical Commission (IEC). This standard specifies clear requirements for the conductor material, insulation material performance, structural dimensions, electrical properties (such as insulation resistance and voltage withstand strength), mechanical properties (such as tensile strength and elongation at break), and testing methods of PVC insulated cables. It ensures that the product meets uniform quality and safety standards during production, inspection, and use, providing users with reliable product guarantees. In summary, with high-quality materials, reasonable structural design, applicable voltage rating, and compliant quality standards, this solid copper core PVC insulated wire becomes an ideal choice for low-voltage electrical wiring, capable of meeting the safe electricity demand in various scenarios.
