Graphite Grounding module

Grounding module is an earthing material with advantage of resistance-reducing and corrosion-resistant. It is made from high conductive graphite powder and silicate with an metal earthing bracket. It has the same effect of resistance-reducing earthing compound but it is more convenient to use. Characteristics: It takes the stable nonmetallic material as module’s medium, so that its conductivity is stable all the year round.It can keep moist. Its earthing is effective.In the area of high earth resistance, it can effectively reduce the grounding system resistance.It is endurable to high power and dash current, the resistance is stable.It’s corrosion resisting, non-toxic, long service time and easy to use. Tech. data Resistance rate testρ≤0.1Ω.m Physical test: water loss test ρ≤0.1Ω.mhot-cold recycle testρ≤0.1Ω.m soaking testρ≤0.1Ω.m Dash current enduring test ΔR%≤10%Power enduring testΔR%≤10%PH test: PH=8-12The corrosion-resistant test of internal metal bracket: the average corrosion rate ≤0.33/ year Method Lay it vertically in earth, the minimum depth is 0.8m;The minimum space between two modules is 4m;When paralleling the metals bracket or connecting with earthing wire, it must adopt welding and the welding length is twice long as the connecting width or adopt exothermic welding. \It is necessary to clean the welding slag, paint corrosion-resistant paint or wrap with resistance-reducing compound;When backfilling earth, it is necessary to water properly, and ram earth . After the module absorb water efficiently (24 hours), measure the earthing resistance.
