Grounding Strand vs Grounding Rod - Kunbian Power Equipment

Grounding strand and grounding rod are two common components in electrical grounding systems, each with distinct characteristics and applications. A grounding rod is typically a solid, cylindrical metal rod, usually made of copper - bonded steel or galvanized steel, driven vertically into the ground. It offers a simple and cost - effective grounding solution, especially suitable for small - scale residential or light - commercial setups. Its installation is straightforward, and it provides a basic connection to the earth. However, the single - point contact of a grounding rod limits its surface area in contact with the soil, which may reduce its effectiveness in dissipating large electrical currents. On the other hand, a grounding strand is a multi - stranded wire, often made of highly conductive materials like copper. It can be laid horizontally or in complex patterns, increasing the contact surface area with the soil. This design allows grounding strands to handle higher - magnitude electrical currents, such as those from lightning strikes or severe electrical faults, more efficiently. Grounding strands also offer greater flexibility in installation, adapting well to various site conditions, making them the preferred choice for large - scale industrial, commercial, or critical infrastructure applications where reliable and high - capacity grounding is essential.
