Question 4: What is the grounding module, the main purpose of the grounding module is what Shengtai grounding module is a conductive non-metallic materials-based grounding body, which consists of conductivity, good stability of non-metallic materials, electrolytes, moisture-absorbing agents and corrosion-resistant metal electrode core. Shengtai grounding module has a large surface area and good contact with the earth, ion dissipation, moisture retention and moisture absorption, easy to construct and other advantages, is to replace the traditional grounding body of the ideal grounding materials. Shengtai grounding module according to the built-in electrode core is divided into two kinds of hot-dip galvanized flat steel and copper row, respectively adapted to the steel and copper and other grounding system. Due to the characteristics of the non-metallic material on the surface of the grounding module, when connecting it to the protected earth line, Shengtai grounding module will greatly reduce the contact resistance with the earth, coupled with the moisture-absorbent nature of the moisture so that it can give full play to its role in the grounding system to reduce the resistance!
Question 5: How to install the grounding module Installation steps of the grounding module
1, the grounding module can be buried vertically or horizontally, buried depth is generally 0.8 ~ 1.0 meters.
2, using several modules buried in parallel, the module spacing should not be less than 4.0 meters. If conditions do not allow, can be appropriately reduced, and at the same time should be reduced to calculate the module dosage module utilization factor value.
3, grounding module pole core parallel to each other or and ground connection, must be welded. Requirements for welding with the same metal material to ensure the reliability of the connection. Welding length should not be less than 80mm, do not allow false welding, leakage welding.
Issue 6: the construction method of grounding module Grounding module generally has two construction methods, look at the construction of the Hengtai grounding module
1, low resistance grounding module can be buried vertically or horizontally, the depth of burial should not be less than 0.6 meters, generally 0.8-1.0 meters.
2, using several modules buried in parallel, the module spacing should not be less than 4.0 meters. If the conditions do not allow, can be appropriately reduced, at the same time should reduce the calculation of module dosage module utilization factor value.
3, low-resistance grounding module pole core in parallel with each other or with the ground connection, must be welded. Requirements for welding with the same metal material to ensure the reliability of the connection. Welding length should not be less than 100mm, does not allow welding, leakage welding.
4, should be welded to remove the welding slag, coated with a layer of asphalt or anticorrosion paint to prevent corrosion of the pole core.
5, trench backfill should be used for fine-grained soil as filler, shall not use broken bricks and other construction waste as backfill. Backfill should be layered operation, fill 30 centimeters of material, the appropriate amount of water and tamping. In the filler, add water and tamping, until flush with the surface. When tamping, attention should be paid even if the module and backfill, backfill and ground contact closely, but do not damage the module itself. Backfill is completed again after watering and moistening.
6, after 72 hours of moisture absorption, the ground resistor to measure the frequency grounding resistance. If the expected target is not reached, the reasons should be analyzed and take remedial measures.
Question 7: What materials are used to make the grounding module ''''' are what proportion of 30 points Qualified products are mostly made of graphite, containing part of the cement component, the specific are manufacturers of their respective formulas
Question 8: How much is the price of grounding module ah Is this? It depends on the raw materials and the production cost of drops. To a 25kg heavy grounding module as an example (600 * 400 * 60mm weight 25kg), calculate the cost: the main component of the grounding module is -185 high-carbon graphite (proportion should be 60%), the secondary components for the silicate and ionic conductive materials and hot-dip galvanized metal rods (proportion of 40%). -185 high carbon graphite market price per ton in about 4800 yuan (carbon in 95% of it), according to the above ratio of production of a 25kg weight grounding module, which high carbon graphite accounted for the cost of the fee should be in about 75 yuan, the cost of minor components of the cost of about 45 yuan. Then add the production costs of workers, wooden packaging costs, transportation costs, taxes, etc. This calculation estimates that the cost of each piece should be about 200 yuan, right? If the manufacturer floating 15% profit, the market price will not be less than 230 dollars per piece. Then you look for the price of those 90 yuan, 100 yuan, 150 yuan and other products inside the raw material ingredients do not need me to say it! Encounter lightning current when a piece of concrete made of grounding module it can drain the current? It can only cause the current backlash, counterproductive, the last bad luck is the equipment. So, manufacturers offer low has low reasons, high has high reason! You'd better decide for yourself!
Question 9: Grounding module has several grounding construction methods Grounding module can be buried vertically or horizontally, buried depth is generally 0.8 ~ 1.0 meters.
Using several modules buried in parallel, module spacing should not be less than 4.0 meters. If conditions do not allow, can be appropriately reduced, and at the same time should be reduced to calculate the module usage module utilization factor value.
Grounding module pole core connected in parallel with each other or with the ground, must be welded. Requirements for welding with the same metal material to ensure the reliability of the connection. Welding length should not be less than 80mm, do not allow false welding, leakage welding.
Welding slag should be removed from the weld, coated with a layer of asphalt or anticorrosion paint to prevent corrosion of the pole core.
The pit should be backfilled with fine-grained soil as filler, not with broken bricks and other construction waste as backfill, backfill should be operated in layers, fill 30 centimeters of material, add water and tamping in the right amount. Re-fill, add water and tamping, until flush with the surface.
After 72 hours of moisture absorption, the ground resistor to measure the frequency grounding resistance. If the expected target is not reached, the reason should be analyzed and take remedial measures.
In cold regions, the module should be buried below the permafrost.
Question 10: How to construct the grounding module, there are several methods Grounding module construction is divided into two methods of horizontal grounding and vertical grounding.
Grounding module specific construction methods:
Grounding module should be buried depth of 0.6-0.8 meters, if the soil resistivity is relatively high, it is appropriate to bury the appropriate depth.
The grounding body should be buried at a distance of 4-6 meters.
Place the grounding module should be cleaned and leveled at the bottom of the trench, so that the grounding module and the bottom of the trench contact smooth.
Welding method using exothermic welding, such as arc welding should be used lap welding, good anticorrosion treatment in the welded parts.
After the laying is completed, backfill soil tamping, measurement.
Installation operations should be in line with national and industry norms.
