The Grounding Module
Product Introduction
The grounding body is usually more metal conductor, the most common are angle steel, round steel, steel pipe,
copper rod, copper mesh, its disadvantages are many materials, high cost, life, poor stability, should not be used
in high resistivity soil area. The grounding module is less material, the mouse is small, long service life, good
stability, especially suitable for high soil resistivity area use.
Grounding module using natural nonmetallic inorganic material point compound and into, with good conductive
properties of carbon crystal as conductive materials, as the magnetic absorption material by using high purity
natural iron ore in the iron atom, the carbon crystal and natural iron ore and silicate material size granular as
conductive materials, all materials is a natural inorganic material.Using this material as grounding materials,
various functions of lightning protection, can achieve the safe use of electricity, the prevention and control of
electromagnetic wave. Because of the material with hydration activity, no corrosion(erosion of soil anti acid
and alkali corrosion medium), non-toxic, suitable for any environment. Buried, no pollution to the soil and
underground water source, very environmental protection characteristics. Grounding the service life of the
module has the characteristics of hydration activity can be as long as 100 years.
Working Principle
The grounding module and grounding wire is tightly connected,natural conductive ore and hydrating Portland
good conductivity, excellent soil affinity, water absorption and water retention, reduce soil and grounding
module impedance, so the failure of impulse current rapidly released into the protection function and achieve
the earth.After release of electrolyte buried, make the soil base and contact ionization,increasing the grounding
body itself release current area, reduce the grounding module and the contact resistance between the soil layer,
the characteristics of the cement matrix module itself with water retention and release of extremely strong
electrolyte (these characteristics are metal materials do not), and then play the drag reduction excellent ability of
grounding module. Can be used in the fields of electronics, electric power, transportation, telecommunications,
building,petrochemical and other needed grounding protection of the body.

The calculation formula of grounding module
According to the soil resistivity grid, use the following formula for calculating grounding module quantity:
After parallel the total grounding resistance:Rnj=Rj/nŋ
Rnj-The total grounding resistance
Rj-Each of the grounding resistance of grounding module(Ω), numerical look-up table (manufacturers)
n-Grounding module number
ŋ-Module adjusting coefficient, normally 0.6-0.9
Product Construction Method
1.The grounding module can be with horizontal and vertical buried depth, it must meet the constant temperature
layer but shall not be less than 0.8m, the deeper the effect to be better.
2.Spacing module and the module suggested by 4m is better, if the environmental conditions do not allow, can
relax or reduced.
3.The bottom line and the grounding module connection by various methods, such as cable crimping terminal
type connection, flat welding connection, if the need to use the fire-clay fusion of connection method.
can purchase the special welding fittings for our company.
4.With the grounding module connected with the dirt, please add water mash-able to benefit its close contacts
with each other to improve the drag reduction effect.
5.Terminal crimping to compaction and tightened the screw, then using 1:2 cement packaging joints, avoid
electrode joint metal parts corrosion, affecting the working life.
6.Please be sure to backfill tamping, so we can get the resistance reduction effect of higher.
Don't add other industry salt and other chlorine salt help resistance reducing material, so as not to damage the grounding module, if you want to get faster resistance reduction effect of higher by fourth more water can be.
