Earthing – Grounding Rods

Earthing – Grounding Rods

Earthing or grounding rods, also known as ground rods or grounding electrodes, are metal rods that are driven into the ground to create a low-resistance electrical connection between electrical systems or equipment and the Earth. These rods are a crucial component of grounding systems in electrical installations and play a vital role in ensuring electrical safety.

The purpose of grounding rods is to provide a safe path for electrical currents to flow into the Earth in the event of a fault or electrical surge. When a fault occurs, excess current is directed to the ground through the grounding rod, causing protective devices (such as circuit breakers or fuses) to trip, thereby disconnecting the faulty circuit from the power source. This prevents electrical shocks, minimizes the risk of fires, and protects electrical equipment from damage.

Conex Earth Grounding Rods are made from high tensile-low carbon steel compelling with requirements of BS 4360 Grade 43 A. Each grounding rod is molecularly bonded by 99.99% pure, high conductivity copper bonding’s, each rod is treated with Benzol-triozole derivatives. Threads on rods are formed by roll threading process, giving threads extra strength, eliminating risk of chipping the threads while driving the rods in the ground.

Solid Copper Earth Rods
Conex Solid copper earth rods are made in two types. Externally threaded and internally threaded. Solid Copper earth rods are used where the factor of corrosion is very high and exceptionally long life is equable. Hence these rods are manufacture from pure and high conductivity hard drawn copper to BS 2874-C 101. These rods are also available with tin plating in order to blueuce the risk of oxidation and increasing shelf life.
