The 0.6/1kV U1000 RO2V, R2V insulated single core copper cables compliant with NFC 32-321 standard include two cross-sectional specifications: 1×120mm² and 1×240mm², suitable for medium and low voltage power transmission scenarios.​ The conductors of this series of cables are made of high-purity copper, which has excellent conductivity, enabling efficient power transmission and reducing energy loss. The insulation layer is made of materials meeting RO2V and R2V standards, with good electrical insulation performance and aging resistance. It can work stably under the rated voltage of 0.6/1kV (U1000) and resist mechanical wear and chemical erosion in the environment.​ The 1×120mm² specification is suitable for power supply of medium-power equipment, such as industrial motors and building distribution trunks; the 1×240mm² is applicable to high-power load scenarios, such as large transformer connections and main cable lines in factory areas. The single core design facilitates flexible laying, adapting to various installation methods such as direct burial, pipe threading and overhead, meeting the wiring needs of different projects.​ In general, with strong compliance, stable performance and wide specification adaptability, this series of cables has become a reliable power transmission solution in industrial, civil and public infrastructure.
