For electrical safety and reliable grounding systems, copper bonded earthing rods are a premier option for use in both commercial and industrial use. These rods are designed by molecularly bonding a thick electrolytic 99.9% pure copper coating onto a high tensile low carbon steel core, providing superior conductivity and superior corrosion resistance. This construction is optimal for ... https://www.pioneerpowers.com/copper-bonded-earth-rod.php
