This product is a green-yellow polyvinyl chloride (PVC) insulated stranded copper grounding wire, available in six specifications: 10mm², 16mm², 25mm², 35mm², 50mm², and 70mm². Specifically designed for grounding protection in electrical systems, it serves as a core component to ensure electrical safety.​ The conductor is made of high-purity electrolytic copper, composed of multiple stranded fine copper wires. The number of strands and diameter of single wires for different specifications are optimized with increasing cross-sectional area: 10mm² typically consists of 49 strands of 0.52mm diameter copper wires; 16mm² has 49 strands of 0.64mm; 25mm² includes 98 strands of 0.58mm; 35mm² features 133 strands of 0.58mm; 50mm² comprises 133 strands of 0.68mm; and 70mm² consists of 189 strands of 0.68mm. The stranded structure endows the wire with excellent flexibility, facilitating bending and threading installation in complex electrical cabinets, building walls, or inside equipment. It is particularly suitable for scenarios requiring frequent adjustment of wiring paths, while reducing the risk of conductor breakage due to bending.​ The insulation layer is made of aging-resistant and wear-resistant PVC material, with a color strictly following international universal standards—alternating green and yellow. This identification is mandatory and unique, clearly distinguishing it from live wires and neutral wires, ensuring it can be quickly identified as a grounding wire in any electrical system, and fundamentally avoiding the risk of misconnection. The thickness of the PVC insulation layer increases with specifications: approximately 1.0mm for 10mm² and up to 1.4mm for 70mm². It boasts excellent electrical insulation performance, capable of withstanding operating temperatures from -15℃ to 70℃, while resisting acid, alkali, oil pollution, and ultraviolet erosion. It can maintain long-term stability even in humid and dusty industrial environments.​ In terms of electrical performance, the rated current-carrying capacity of each specification wire matches its cross-sectional area: 10mm² is approximately 50-60A, 16mm² is 65-80A, 25mm² is 90-110A, 35mm² is 110-135A, 50mm² is 140-170A, and 70mm² is 180-220A. All are applicable to grounding circuits with AC 50Hz and rated voltage of 450/750V or below. Its core function is to reliably connect the metal enclosures and frames of electrical equipment to the ground. When a leakage occurs in the equipment, it can quickly conduct the fault current into the ground, reduce the voltage of the enclosure to the ground, prevent electric shock to personnel, and trigger protective devices (such as circuit breakers) to cut off the power supply, avoiding the expansion of accidents.​ This grounding wire is widely used in low-voltage power distribution systems in industrial plants, commercial buildings, power stations, rail transit, etc., adapting to the grounding needs of various electrical equipment such as motors, transformers, and switchgear. The product production strictly complies with standards such as GB 50169 and IEC 60445, and passes multiple tests including insulation withstand voltage, conductor resistance, and aging resistance, ensuring low impedance and high reliability of the grounding circuit, and building a solid defense for the safe operation of electrical systems.

Bare or green/yellow stranded copper grounding wires (with specifications covering 6 AWG, 2 AWG, 1/0 AWG, 2/0 AWG) are safety cables specifically designed for equipment grounding. Their core function is to reliably connect the metal enclosures and frames of electrical equipment to the ground, forming a discharge channel for fault currents, thereby preventing electric shock accidents caused by electrified equipment, stabilizing system voltage, and ensuring the safe operation of electrical systems. Their diverse specifications adapt to the grounding needs of equipment with different power levels, and they are key components for equipment safety protection in industrial, commercial, and civil fields.​ In terms of conductor characteristics, stranded copper material is its core advantage. High-purity electrolytic copper has excellent conductivity, which can quickly conduct fault currents and ensure the timeliness of grounding response; the multi-strand stranded structure endows the wire with good flexibility, making it easy to install and fix in scenarios such as narrow spaces inside equipment and curved wiring, reducing construction difficulty. The current-carrying capacity of different specifications varies significantly: 6 AWG is suitable for small equipment (such as household appliances, office equipment) with a current-carrying capacity of about 55-75A; 2 AWG can meet the grounding needs of medium-sized industrial machinery (such as water pumps, fans) with a current-carrying capacity of 95-125A; 1/0 AWG and 2/0 AWG are suitable for large equipment (such as transformers, generator sets) with current-carrying capacities of 150-180A and 180-220A respectively, which can cope with high current impacts.​ In terms of appearance and identification, the bare wire version has no insulation layer and directly exposes the copper conductor, suitable for dry, dust-free enclosed environments (such as grounding inside control cabinets); the green/yellow version adopts the internationally universal grounding identification color, and the outer layer is usually wrapped with a PVC insulation layer, which has both insulation protection and intuitive identification functions, suitable for exposed installation or humid environments (such as outdoor equipment, humid workshops). This color identification can effectively avoid wrong connections and ensure the correctness of the grounding loop.​ The applicable scenarios are wide: in the industrial field, it can be used for grounding the enclosures of production line equipment, machine tools, and distribution boxes; in commercial buildings, it is suitable for safety grounding of air conditioning units, elevators, and large lighting equipment; in civil scenarios, it can be used as a grounding branch for home appliances such as washing machines and refrigerators. In addition, its high conductivity and mechanical strength can also provide reliable guarantee in the grounding of transformers, distribution cabinets in power systems, and equipment in communication base stations.​ In terms of performance, this series of grounding wires strictly complies with international grounding standards (such as IEC, UL) and has passed multiple tests such as conductivity, mechanical strength, and corrosion resistance. The copper conductor of the bare wire has undergone anti-oxidation treatment, which can reduce oxidative rust; the PVC insulation layer of the green/yellow wire has a temperature resistance range of -15℃ to 70℃, strong moisture resistance, and can resist moisture and slight chemical erosion in daily environments.​ In summary, with multi-specification adaptability, high-conductivity stranded copper material, clear identification design, and reliable performance, bare or green/yellow stranded copper grounding wires have become an ideal choice for equipment grounding systems, building a solid defense line for the safe operation of various electrical equipment.
