This product is a rigid power cable (Xvb Fil Electrique) with models such as U-1000 R2V, R02V, and U1000 RO2V, covering two specifications: 3G 1.5mm² and 3G 2.5mm², with a black appearance.​ The cable has a rated voltage of 1000V, which is suitable for low-voltage power systems and can stably transmit electricity in low-voltage power supply environments such as residences and small commercial places. It adopts a rigid structure design, which has good shape retention and is not easy to deform after installation, making it suitable for fixed laying scenarios.​ The conductor is made of high-quality materials, with good conductivity, which can reduce transmission loss; the insulation layer has excellent insulation performance, which can effectively prevent electric leakage. The 3-core structure is suitable for three-phase or single-phase power transmission. 3G 1.5mm² is applicable to low-power scenarios such as lighting lines and small household appliances, and 3G 2.5mm² can meet the power supply needs of slightly higher-power equipment such as household air conditioners and small electric tools.​ Its black appearance is simple and dirt-resistant, and its rigid characteristics make it perform stably in fixed installations such as open laying, and it is widely used in indoor power wiring of civil buildings.
