earth rod clamp

Our company supplies various ground rod accessories.

1. We are continuously developing new products that contribute to safer ,more convenient and economic lightning protection systems.

2. We can design and make the mold , so we can make products as per customer's drawings or samples

GRD copper bonded ground rods meet all the requirements of the world’s most rigorous standard such as UL-467,ANSI C-33-8,CE B-S10030250 .Carbon steel core coated with an electrolytic copper layer,which is minimum 99.9% pure with no trace of zinc.The copper layer is bonded to steel core through an electrolytic process ,which is the most advanced 4-dimensional continuous plating method,which ensures a perfect and even bonding between the copper and steel. The rod finishing is brilliant,free of imperfections or  peelings.

Technique Parameters:

UL ground rod.copper thickness is equal or above 0.254mm.Electricity resistivity is less than 0.059Ωmm2.Tensile strength is equal or above 600N/mm2.Anti-corrosion:put in concentration of 10% nitric acid,soaking for more than 90 hours,no corrosion weight loss is more than 15%.Copper bonding strength: sustain heat above 300 °C up to 1 hour after the quench,the copper layer is not peeled off.Copper coating plasticity: bend the ground rod to 180 degree,the copper layer doesn’t break or peel.
