A green-yellow ground wire is usually a wire or conductor that is characterized by an outer covering of green-yellow insulation. It is mainly used in grounding systems in buildings, electrical equipment and circuits. The main function of the yellow-green ground wire is to flow the current to the ground to ensure the safety of people and equipment.
The yellow-green grounding wire is usually braided by multiple strands of thin copper wire, which makes it have good electrical conductivity and flexibility. Its insulating layer is usually made of PVC (polyvinyl chloride) or PE (polyethylene) material to provide electrical insulation and protection. The yellow-green color is mainly used to distinguish the function of the ground wire from other wires, and it is usually added to the insulation layer with a special dye to ensure easy identification. The yellow-green ground wire must be properly connected to the grounding system of the building or equipment. It is usually welded or connected to the underground of the building, or connected to the metal shell or grounding terminal of the equipment. The end of the ground wire is usually inserted into the ground to ensure a good connection to the ground below. Proper use and connection of the yellow-green ground wire is critical to maintaining the safety of the circuit. It is able to direct any potential current leakage or fault current to ground, avoiding the risk of electric shock and fire. Therefore, when installing, maintaining, or changing electrical equipment or circuits, it is critical to ensure that the green-yellow ground wire is properly connected and tested.
