Grounding module (cylindrical)
Product description
| I
product introduction The grounding module is a kind of grounding body mainly made of non-metallic materials
It is composed of composite non-metallic materials with good conductivity and stability, hygroscopic agent and electrolytic substances
It not only has the characteristics of long-term, anti-corrosion, resistance reduction and so on
Compared with the resistance reduction agent, the construction is more convenient, and the grounding module is less affected by dry humidity
It can absorb moisture for a long time and keep low resistance unchanged
VAF series non-metallic grounding body shall comply with the enterprise standard: q/cd-2004
This product has been tested by the State Grid wugao Institute
According to the Lei Zi 2008 No
14 document, the items submitted for inspection are completely qualified, and it is completely produced according to the enterprise standard
working principle:
Mafl series grounding module has built-in metal electrode, which is connected with the ground wire of the protected object, so that the grounding current can be quickly discharged to the ground, so as to obtain low grounding resistance
Its mechanism: it increases the dissipation area of the grounding body itself, reduces the contact resistance between the grounding body and the soil layer, has strong moisture absorption and moisturizing ability, and gives full play to the conductivity of the module material
Product features:
SWL series physical resistance reducing agent shall comply with the quality standard of technical conditions for grounding resistance reducing agent issued by the Ministry of energy
Product technical parameters: resistivity ≤ 0
5Ω
m； PH＞7； Corrosion rate <0
03mm/ year
2、 Technical advantages 1
Corrosion resistance:
Electrode graphite is a good conductive inert material, which has no chemical reaction with metal
Gels and their additives are strong alkali and weak acid salts, which have corrosion resistance to metals
Metal passivator can quickly passivate the surface of metal grounding body during construction and effectively prevent the corrosion of metal grounding body
During on-site construction, the physical resistance reducer is mixed with water to form a colloid, which is tightly attached around the grounding metal electrode after solidification, which prevents the infiltration of oxygen and the invasion of soil corrosive media
2
Conductivity stability:
The electrode graphite exists in the physical resistance reducer, which will not undergo physical and chemical changes after solidification into the underground grounding body
The resistance reducer itself has strong water absorption and moisture retention properties, and its composition will not be lost due to seasons
Therefore, the conductivity is not affected by high and low temperatures, dry humidity and environmental media
3
Resistance reduction efficiency:
The resistivity of physical resistance reducer is far less than that of soil
During construction, the cementitious liquid and soil are solidified into a grounding body through limited penetration, which is closely combined with the metal
The effective contact surface between the metal electrode and the resistance reducing agent layer and between the resistance reducing agent layer and the soil is increased, and the contact resistance is reduced, which is conducive to stable discharge and resistance reduction
The resistance reducer itself has strong water absorption and moisture retention properties, which can maintain the moist state in the soil near the electrode for a long time, reduce the resistivity of the soil around the electrode, and thus reduce the contact resistance between the electrode core and the soil
