Strong corrosion resistance Electrolytic Ground Rod 8mm - 25mm

Technical Specification       

                                                                     
1) The purity of the copper which used as cladding is more than 99.95%.

2) The steel core is low carbon steel which the carbon content is about 0.15%.

3) The copper bonded ground rod will be capable of being through 90 at a maximum radius of 100mm with no copper fracture and with no ill effect on the bond between the steel and the copper cladding.

4) Good in anticorrosion that usage-life is more than 50 years, constant low resistance and good plasticity which has the characteristics of the pure copper.

5) The earth rod is fully covered with copper cladding without any cracks, holes, cavities etc. Preventing exposure of the steel core to soil and moisture, so as to form a good corrosion resistance.

Instruction of Use

1. Drilling

Dill the hole about 140mm×3500mm on the earth , or dig the channel about 300mmx3500x800mm and install the grounding rod . Multi grounding rods should be connected by the channel 350mmx600mm.

2. Install the ion grounding rod and connect lead wire;

Remove the seal tape of water absorbing hole and releasing hole (Must );

Put the electrode into assy hole;

Connect the lead wire with anti-corrosion bolt and welded with exothermic welding;

If grounding grid is needed with multi grounding electrodes , 95mm2 copper stranded wire or galvanized round wire or galvanized tape is recommended to connected with exothermic welding.

3. Fix bentonite and water and fill

Fix bentonite and water with the ratio 1:1;

Fill the bentonite and about 50mm higher than electrode , and stir with stick to exhaust the air;

Check the connect the refill the soil ,no stone ,stick or plastic piece left.

4. Test the resistance

Test the resistance 3 days later after installation , and retest one month later and six month later to observe the change.
