The 100m roll of 2.5mm² solid copper wire with PVC insulation, rated at 450/750V, is a reliable and practical electrical wiring product, widely applicable to various civil, commercial and light industrial scenarios.​ Its core conductor is made of high-purity solid copper. The cross-sectional area of 2.5mm² endows it with excellent current-carrying capacity, which can stably transmit electricity, reduce energy loss when current passes through, lower the risk of heating caused by overload, and ensure the safe operation of the circuit. The solid copper conductor not only has excellent conductivity, but also has strong mechanical strength, resistance to stretching and bending, is not easy to break during installation, and can adapt to complex wiring environments. At the same time, the surface of the copper conductor has undergone special treatment, which can effectively resist oxidation and corrosion, prolong the service life of the wire, and can maintain stable performance even in humid, dusty and other environments.​ The insulation layer is made of high-quality polyvinyl chloride (PVC) material, which has excellent insulation properties, can reliably isolate current, and prevent potential safety hazards such as electric leakage and short circuit. PVC material also has good flame retardancy. When exposed to fire, it burns slowly and produces little smoke, adding a layer of safety protection to the circuit. In addition, the insulation layer is wear-resistant and chemical corrosion-resistant, can withstand a certain degree of mechanical impact and temperature changes, and has a wide applicable temperature range. It can work normally in the environment of -15℃ to 70℃, and is competent for exposed laying, concealed embedding or pipe threading.​ The voltage rating of 450/750V means that this wire can be used in circuit systems with an insulation voltage of 450V to ground and 750V between lines, and is suitable for main lines and branch lines in family residences, lighting and power systems in commercial places, power supply for small office equipment and other scenarios. For example, in families, it can be used to connect the lines of high-power household appliances such as air conditioners and electric water heaters; in shops, it can provide stable electricity for equipment such as freezers and display cabinets. The 100m roll design is convenient for construction personnel to cut according to actual needs, reducing waste, and at the same time facilitating transportation and storage.​ This product is produced in strict accordance with relevant industry standards. Every link from raw material selection to finished product inspection is strictly controlled to ensure that its electrical performance, mechanical performance and safety performance meet the regulatory requirements. Whether in home decoration, commercial decoration or small engineering projects, this 2.5mm² solid copper PVC insulated wire is a trustworthy choice, which can provide stable and safe power transmission support for various electrical systems.
