Low Resistance earth electrode

       Overview:

It is a common scientific method that use X-K grounding module to reduce ground resistance in grounding works, according to soil condition, install moderate amount of module, can reach the requirement of ground resistance≤1Ω. Use the module, not only maximize reduce grounding resistance, but also guarantee the grounding conductor keep stable for a long time, the life of it is over 30 years. It has moisture absorption and moisture ability, the ground resistance is low and can remain stable for a long time, after large current shock many times, the resistance value can not increase, and the electrode is not harden and breakage, compared with resistance-reducing agent, it has obvious superiority. It is capable of withstanding lower temperatures of -40°C, so also suitable for north high-cold region.

The grounding module is called “grounding treasure”, is a grounding conductor based on non-metal materials, It consists of non-metallic minerals and electrolytes which has good conductivity and stability, it is mainly used as building grounding, lightning protection grounding, ESD grounding, traffic working grounding, safety protection grounding and grounding system with other purpose. The grounding module starts a new area of grounding material and grounding technology.

       Technical data:

Model No.	Size(mm)	weight	Power Frequency Ground Resistance	Resistivity(under room temperature)
SY-D-01	500×400×60 (flat type)	20kg	≤8.5Ω	≤3Ω.m
SY-D-02	φ150×850 (column type)	20kg	≤8Ω	≤3Ω.m

       Main feature:

Anticorrosion, nonhazardous, long life, easy to install, reduce the work done.Can absorb moisture and keep moisture, low ground resistance.Shock-proof to large current, the resistance value is not increase, and the electrode is not harden and breakage.Effective reduce the ground resistance of high resistivity soil.Small effects by season, the resistance value can be kept stable for a long time.

       Working principle and effect:

Reduce contact resistance: the host material of ground module is similar to the physical structure of soil, can combined with the soil, make the effective contact area between ground conductor and soil is much bigger than metal ground conductor, increase the effective scattered flow area, reduce the contact resistance, so can improve efficiency, reduce earth mat occupy land area.Resistance stability: the module has strong moisture absorption and moisture ability, can make around soil keeping moisture, ensure the ground module effective play conductive function, at the same time, the conductivity of conductive objects in ground conductor is not influenced by humidity and temperature change, so can supply stable ground resistance.Reduce counterattack of ground voltage: the non-metal material of grounding module make formed a low resistance area between metal and soil, when large current shocks, can reduce transient potential gradient of grounding conductor and ground lead, reduce cross voltage and contact voltage, reduce the probability of local potential counterattack.Long life: the main body use anticorrosion material, the metal skeleton use the metal material that surface anticorrosion treatment. Life for 30 years.

       Dosage calculation:

 

Formula: N=ρ*M/Rn*K

(The calculation result is converted to an integer when it is a decimal.)

ρ---electrical resistivity of soil.

M---coefficient of grounding, the numeric range is 0.11~0.15, the larger ρ value, the smaller M value.

Rn---the value of ground resistance.

K---utilization factor, the numeric range is 0.7~0.85, the greater the module quantity, the smaller K value.

The relationship between every factors can refer to the following table.

electrical resistivity of soil(ρ)	coefficient of grounding(M)	utilization factor(K)
ρ<200Ω.m	0.15	0.85
200≤ρ<500Ω.m	0.14	0.75~0.8
500≤ρ<1000Ω.m	0.12	0.75~0.8
ρ≥1000Ω.m	0.11	0.75
