The 35mm² green-yellow stranded copper ground cable is a dedicated cable designed for safe grounding of electrical systems. It features polyvinyl chloride (PVC) insulation and a rated voltage of 600V, playing a crucial role in ensuring safety in various buildings, industrial facilities, and power engineering projects.​ In terms of structure, the cable's conductor consists of multi-stranded copper wires with a cross-sectional area of 35mm². Copper boasts excellent electrical conductivity, and the stranded design enhances the conductor's flexibility and mechanical strength, making it easier to bend during installation, adapting to complex environments, and reducing the risk of breakage caused by vibration or temperature changes. The 35mm² cross-section ensures sufficient current-carrying capacity, enabling rapid conduction of fault currents into the ground to prevent electric shocks or equipment damage.​ The insulation layer is made of PVC, which not only provides good electrical insulation to prevent short circuits between the ground cable and other conductors but also offers wear resistance, acid-alkali corrosion resistance, and certain weather resistance. This protects the internal copper conductor from external environmental influences, extending the cable's service life. Notably, the cable's outer sheath adopts the internationally recognized green-yellow color combination, a distinct 标识 that clearly indicates its grounding function, facilitating quick identification by installers and avoiding misconnections to ensure the correctness of the grounding system.​ In terms of performance, the cable has a rated voltage of 600V, suitable for grounding circuits in low-voltage electrical systems. It features an extremely low grounding resistance, allowing efficient conduction of fault currents. When electrical equipment experiences leakage or short circuits, the cable can quickly divert the current into the ground, reducing the voltage to ground on the equipment's outer shell and ensuring personal safety. Additionally, the PVC insulation layer can operate stably in an ambient temperature range of -15℃ to 70℃, adapting to climatic conditions in different regions.​ Regarding application scenarios, this cable is widely used in grounding systems of industrial plants, commercial buildings, residential communities, and municipal engineering. In industrial equipment, it can connect the metal enclosures of motors, distribution cabinets, etc., to grounding electrodes, forming protective grounding. In building electrical systems, it can serve as a connecting wire for lightning protection grounding, linking lightning rods, lightning strips, and other lightning receptors to the grounding grid to conduct lightning currents. In household electricity, it can be used with residual current devices to enhance electrical safety.​ Furthermore, the cable offers flexible installation methods, including surface mounting, concealed installation, or pipe threading. It requires no complex maintenance procedures, only regular inspections to check for insulation damage and secure connections. Its standardized green-yellow design complies with International Electrotechnical Commission (IEC) standards and electrical regulations of various countries, ensuring universality in transnational projects or import-export initiatives.​ In summary, the 35mm² green-yellow stranded copper ground cable, with its excellent conductivity, reliable insulation protection, clear functional identification, and wide applicability, has become a key component in ensuring the safe operation of electrical systems, providing solid grounding protection for personnel and equipment safety.
