The Fil É Lectrique Th 1.5mm² rigid copper cable, as an H07V-U equivalent product, features a 1.5mm² cross-sectional area, a rated voltage of 450/750V, a rigid copper conductor, and is available with blue, red, or green/yellow insulation layers in a 100m roll design. It is a universal cable specially designed for low-voltage fixed electrical systems. Its performance fully complies with the strict requirements of the H07V-U standard for conductor materials, insulation performance, and temperature range. It can be widely used in lighting, socket, and other low-to-medium power fixed wiring scenarios in residential buildings, commercial buildings, and industrial auxiliary areas. With stable electrical conductivity, reliable insulation protection, and standardized color identification, it provides a safe and efficient power transmission solution for various electrical systems, while meeting the dual needs of construction convenience and long-term use stability.​ In terms of specifications and parameters, the 1.5mm² cross-sectional area of the cable is accurately calculated through engineering, focusing on low-to-medium power current transmission needs. Its conductor can stably carry the rated current in line with the H07V-U standard. During long-term fixed operation, it can effectively control voltage drop and heat generation, making it suitable for residential lighting circuits, power supply for ordinary sockets, and fixed wiring of small commercial equipment. It avoids circuit faults caused by current overload or excessive loss. The 450/750V rated voltage design has a clear functional division: 450V is the normal working voltage, suitable for most low-voltage power distribution systems; 750V is the insulation withstand voltage value, providing an additional safety margin, which can resist electrical stress caused by voltage fluctuations, ensuring that the insulation layer does not break down or leak electricity. As an H07V-U equivalent product, the cable strictly follows the temperature resistance requirements of the corresponding standard and can work stably in an environment of -30°C to 70°C. Whether it is a low-temperature outdoor junction box or indoor wiring close to heat sources, it can maintain the structural integrity of the conductor and insulation layer, without brittleness, softening, or other problems due to extreme temperature changes. In addition, the 100m roll design provides convenience for construction. It can not only meet the cable dosage needs of small and medium-sized projects but also facilitate cutting as needed, reducing the number of joints and lowering the risk of faults. At the same time, the roll design is conducive to storage and transportation, preventing the cable from being damaged during handling.​ In terms of material and structural design, the cable uses rigid copper (Cuivre Rigide) as the conductor core. Rigid copper material has two core advantages: First, its high-purity characteristic brings excellent electrical conductivity, with extremely low resistivity, which can minimize energy loss during current transmission and reduce electricity costs in long-term use. Second, it has high mechanical strength, which is not easy to deform during fixed installation (such as pipe threading and wall embedding), and can maintain a stable wiring shape. It makes closer contact with terminals and connectors, reducing contact resistance and avoiding safety risks caused by local heating. The insulation layer material meets the requirements of the H07V-U standard and has excellent electrical insulation, corrosion resistance, and mechanical toughness: Electrical insulation can effectively isolate the conductor from the outside world, preventing leakage accidents; Corrosion resistance can resist moisture, dust, and slight chemical erosion in the air, extending the service life of the cable; Mechanical toughness ensures that when the cable is subjected to slight friction and extrusion during construction, the insulation layer is not easy to be damaged, protecting the conductor from harm.​ The color identification design is an important practical feature of this cable. The blue, red, and green/yellow colors strictly follow the electrical industry standards: blue is usually used for neutral wires, red for live wires, and green/yellow two-color for grounding wires (specifically, it needs to be combined with local electrical specifications). The standardized color distinction can help installers quickly identify the function of the cable, avoid wiring errors, especially in complex electrical wiring environments, which can greatly improve construction efficiency. At the same time, it provides clear guidance for later maintenance and fault diagnosis, reducing maintenance delays caused by cable confusion.​ In terms of application scenarios, relying on its H07V-U equivalent performance and multi-color options, this cable covers a wide range of application fields. In residential scenarios, it can be used as fixed wiring for lighting circuits and ordinary sockets in bedrooms/living rooms. The blue neutral wire, red live wire, and green/yellow grounding wire are used together to build a safe home power distribution system. In commercial buildings (such as small offices and convenience stores), it is suitable for fixed power supply lines of lighting systems, cash registers, small air conditioners, and other low-to-medium power equipment. Its stable performance ensures continuous and reliable commercial electricity use. In industrial auxiliary areas, it can be used for fixed wiring of small auxiliary equipment and control circuits, withstanding slight vibration and dust interference in industrial environments. In addition, its 100m roll design is particularly suitable for partial renovation projects or small and medium-sized new construction projects, without the need for large-scale stockpiling, reducing inventory costs. At the same time, the feature of cutting as needed reduces cable waste, in line with the concept of green construction.​ In terms of safety and compliance, as an H07V-U equivalent product, the cable must pass a number of strict tests, including dielectric strength test (verifying the voltage withstand capacity of the insulation layer), temperature resistance test (confirming performance stability in high and low-temperature environments), and conductor resistance test (ensuring that the electrical conductivity meets the standard), to ensure that the product meets safety standards. At the same time, the combination of the cable's rigid copper conductor and high-quality insulation layer has good flame retardant performance (complying with relevant industry standards). In case of accidental fire, it can delay the spread of flames, gaining time for personnel evacuation and emergency treatment, further improving the safety of use.
