This product is a U1000 RO2V type power cable, covering three specifications: 3G4mm², 3G25mm² and 3X240mm². "U1000" indicates that the rated voltage of the cable is 1000V, which is suitable for low-voltage power systems; "RO2V" is a model identifier, indicating that it adopts an insulation and sheath structure that meets standards and has stable electrical performance.​ The cable insulation layer is made of high-quality materials, with high insulation resistance and excellent voltage resistance, which can effectively block current leakage and ensure the safety of power transmission. The conductor is made of high-purity copper, which has good conductivity and can reduce energy loss during transmission. The 3-core structure design is suitable for three-phase or single-phase power transmission needs, and different cross-sectional area specifications can meet diverse scenarios: 3G4mm² is suitable for low-power scenarios such as small household appliances and lighting lines; 3G25mm² can be used for medium-sized equipment power supply and building branch lines; 3X240mm² is suitable for heavy-duty scenarios such as industrial high-power equipment and main lines of large building complexes.​ This series of cables is easy to install and suitable for indoor open laying, pipeline laying and other environments, and is widely used in low-voltage power distribution in civil buildings, commercial places, small industrial facilities and other fields.
