Do you know what helps maintain the safety of you and your electrical appliances from fault current? A metal rod called Earth Rod. These Copper Rods establish quality earthing systems in overhead, underground electricity distribution and transmission networks. They provide ground contact in all soil conditions like high voltage substations, towers, and power distribution applications. This Copper Rod for grounding dissipates faulty current in the ground and ensures safety. Let’s have a look at the different types of Copper Rod used for grounding.
Copper Rods for grounding are essential components used to establish a secure and efficient connection to the earth, facilitating a pathway for electrical currents to safely dissipate into the ground. These rods are designed to meet the IEC 62561 Part 2 standards, ensuring they uphold the highest quality and safety measures. Comprising 99.9% pure electrolytic copper bonded to a durable low carbon steel core, they offer enhanced mechanical tensile strength and superior corrosion resistance.
