Ground Wire is essential for the protection and safety of electrical systems, providing a path to ground for fault currents and reducing the risk of electrical shock or fire. These wires are often made of copper or aluminum and may be solid or stranded. They are used alongside utility poles, transmission towers, and in substations to enhance the grounding system's effectiveness and ensure safety regulations are met. Ground wires can also be clad with materials like aluminum or lead for additional corrosion resistance.
