Description
Our earthing materials and earthing accessories are correctly designed and installed to safeguard both lives and equipment. They have the ability to transfer current to earth with ease. Some of the main features of our earthing materials include-
- Low electrical resistance to earth
- Good corrosion resistance
- Ability to carry the required current repeatedly
- A reliable life of at least 30 years
Quality earth rods are commonly made from either solid copper, stainless steel or copper bonded steel. It is ideal due to its combination of strength, corrosion resistance, and comparatively low cost.
There are four type of earthing materials –
- 1. Galvanized Earth Plates
- 2. G.I Earthing Strips
- 3. G.I Earthing Wire 8 g
- 4. G.I Stay Wire 7/10
