Plate Earthing Copper /GI
An earthing metal should be capable to endure and dissipate a fault current into the ground rapidly. An earthing may be pipe/rod driven into ground or plate .Earthing pipe/rod or plate should be of good quality material which has good electrical properties. Copper and Galvanised Steel are widely used metals in earthing industry. Galvanised steel type are prefer over others due to its anti corrosion properties and low cost. The galvanization process deposits a thick layer of zinc over mild steel pipe. The electrical conductivity of this galvanised pipe does not vary much as compare to steel. But the corrosion rate of this galvanised pipe decrease, thus increase life expectancy of earthing.
