The 70mm² Copper Conductor Green/Yellow PVC Insulated Earthing Cable is a key supporting product for ensuring electrical safety in electrical systems. Its core function is to conduct leakage current that may be generated by the outer casings of electrical equipment, metal components of circuits, etc., to the ground, thereby preventing electric shock accidents and equipment damage. It is widely used in various scenarios requiring reliable earthing protection, such as industrial workshops, civil buildings, power facilities, and rail transit. Its unique green-yellow dual-color insulation design and precise specification parameters make it play an irreplaceable safety protection role in earthing systems, and it is a professional earthing solution that complies with international and domestic electrical safety standards (such as GB 50169-2016 "Code for Construction and Acceptance of Earthing Devices" and IEC 60446).​ In terms of core specifications and materials, the conductor of this earthing cable is made of high-purity electrolytic copper, with a cross-sectional area of 70mm². The setting of this specification fully considers the demand for high-current earthing - the DC resistance of the 70mm² copper conductor at 20℃ is ≤0.268Ω/km, and the rated current-carrying capacity (when laid in air at an ambient temperature of 30℃) can reach 225A. It can quickly divert the large current generated during short circuits or leakage, avoiding the risk of the equipment casing being charged due to current accumulation. The conductor adopts a stranded stranding process, composed of hundreds of fine copper wires with a diameter of 0.2mm stranded according to a specific pitch. Compared with solid hard copper conductors, its flexibility is significantly improved, and the bending radius can reach 6 times the outer diameter of the cable (at room temperature). In complex scenarios such as pre-embedding in building walls, internal wiring of equipment, and laying in cable trenches, it can easily adapt to irregular wiring paths, reduce construction difficulty, and minimize the risk of conductor damage caused by bending.​ The insulation layer is another core component of this earthing cable, made of polyvinyl chloride (PVC) material, and strictly adopts a green-yellow dual-color design in accordance with international standards - yellow and green are distributed alternately at a 1:1 ratio. This color combination is an internationally recognized dedicated identifier for earthing, allowing construction and maintenance personnel to quickly identify the earthing circuit and avoid confusion with live wires and neutral wires, thereby reducing safety hazards caused by wiring errors from the source. The PVC insulation layer not only has excellent electrical insulation performance - when a 500V DC voltage is applied at 20℃, the insulation resistance is ≥100MΩ, which can effectively isolate the conductor from external components and prevent accidental leakage of the earthing circuit - but also has good weather resistance and mechanical strength. Within the operating temperature range of -15℃ to 70℃, the insulation layer shows no brittleness or softening. After a 1000-hour thermal aging test (at 100℃), the tensile strength retention rate is ≥80% and the elongation at break retention rate is ≥70%, which can adapt to various indoor and outdoor environments and resist friction, extrusion, and slight chemical corrosion (such as moisture and dust in the air) during daily use.​ In terms of performance advantages, the high-conductivity copper core and low-resistance characteristics of this earthing cable can ensure that leakage current is conducted to the ground quickly and with low loss. The earthing resistance can be stably controlled below 4Ω (meeting the earthing resistance requirements of most scenarios), ensuring the timeliness and effectiveness of earthing protection. For example, when the outer casing of industrial equipment is charged due to insulation damage, the 70mm² copper conductor can conduct the leakage current to the ground within 0.1 seconds, triggering the leakage protector to trip and cut off the main power supply, thereby preventing electric shock accidents when personnel touch the equipment. At the same time, the flame retardancy of the PVC insulation layer reaches UL94 V-0 level. In case of fire, the flame can self-extinguish within 10 seconds, and no drippings ignite surrounding combustibles, which can effectively prevent the spread of fire and reduce accident losses.​ In terms of application scenarios, this earthing cable covers a wide range of fields. In industrial workshops, it is often used for the casing earthing of large mechanical equipment (such as CNC machine tools, injection molding machines, high-voltage motors), as well as the protective earthing and working earthing of power distribution systems, ensuring the stable operation of production equipment and the safety of operators. In civil buildings, it is suitable for lightning protection earthing of high-rise buildings, protective earthing of household appliances (such as air conditioners and water heaters), and earthing main lines in elevator machine rooms and power distribution rooms, building a comprehensive safety barrier for household and building electrical use. In power facilities, it can be used as a branch line of the earthing grid in substations and power distribution rooms, connecting the earthing electrode and the equipment earthing terminal to ensure the safe and stable operation of the power system in case of short-circuit faults. In the field of rail transit, it can also be used for equipment earthing and track earthing in subway stations and light rail lines, coping with complex electromagnetic environments and high-current earthing requirements.​ In addition, this earthing cable also has the characteristics of convenient installation and low maintenance cost in practical applications. Both ends can be crimped with copper lugs, terminals, and other connectors according to requirements, enabling quick and reliable connection with the equipment earthing terminal or earthing electrode. The intuitive green-yellow dual-color identification facilitates quick positioning of the earthing circuit during later maintenance and troubleshooting of earthing faults. The aging resistance of the PVC insulation layer enables the earthing cable to have a service life of more than 15 years, reducing the cost and labor consumption caused by frequent replacement. Overall, the 70mm² Copper Conductor Green/Yellow PVC Insulated Earthing Cable, with its reliable conductivity, clear identification design, excellent insulation protection, and wide applicability, has become a "lifeline" for ensuring safety in electrical systems, providing a solid guarantee for electrical safety in various scenarios.
