Product introduction

"Zero-ohm composite grounding body" is a new grounding product developed by Shanxi Jielitong Lightning Protection Technology Co., Ltd. to solve the problems of difficult construction of urban hardened roads, easy corrosion of grounding bodies, unstable conductivity, and environmental soil pollution.

It can effectively solve problems, make grounding simple and practical, and increase the life of the grounding. It is especially suitable for urban hardened roads that are difficult to excavate, deep well grounding, high soil resistance, highly corrosive situations, and coastal areas.

The research and development method of "zero-ohm composite grounding body" is scientific and rigorous. The main materials are petroleum extracts, carbon, high-purity graphite, copper, etc., combined with the advantages and disadvantages of traditional products.

After nine years of step-by-step research and verification, it breaks the leakage connection module of traditional metal parts, realizes composite material contact connection and internal metal connection, and solves the problem of gaps between the metal products and the resistance reduction module after corrosion, resulting in the interruption and failure of the graphite grounding grid.

Product advantages: light weight, low resistivity, excellent mechanical properties, good anti-corrosion performance, environmentally friendly and pollution-free, long service life, wide application range, and small footprint.

Size	Usually there are diameter, length and other specifications (such as diameter 20mm, length 1000mm, etc.).
Resistance value	The ground resistance is less than zero ohms, ensuring the lowest resistance.
Installation method	Buried installation.

Features

The specific gravity of the zero-ohm composite grounding body is only 1/5 of copper. It is lighter, convenient, lightweight, and easy to carry and construct.
Small resistivity: The grounding body resistivity test result: ≤0.226μΩm, the electrical conductivity is comparable to that of a metal conductor (pure copper, etc.) with good conductivity, which is conducive to the construction of a high-quality ground network and is not easy to be stolen.
The flexural strength of the zero-ohm grounding body is ≥ 13.7Mpa. During the construction of the grounding grid, the zero-ohm composite grounding body has good toughness and is not easy to be damaged.
Good anti-corrosion performance. Since the zero-ohm composite grounding body is produced and formed by high-temperature sintering and high-temperature electrolysis, it is filled with many dense pores, impurities are not easy to penetrate into the graphite, and chemical reactions between the molecules in the soil and the graphite molecules are not easy to occur. The product structure itself can play a good protective role, and is especially suitable for grounding in dry soil.
The zero-ohm composite grounding body has strong stability. The product is made by high-temperature electrolysis. All harmful impurities are discharged. It is chemically inactive, non-polluting, insoluble in water, dilute acids, dilute alkali and organic solvents. It will not change the surrounding soil and is adaptable to many special and high-demand environments.
Packed in wooden boxes or aviation aluminum boxes, saving transportation costs.
The product has a long service life. The chemistry between molecules of the zero-ohm composite grounding body becomes very stable, so the product is not easy to corrode, has a long life, is not easily broken, and can have a service life of more than 50 years.
It can absorb moisture and retain moisture, maintain effective contact with the soil, and effectively reduce grounding resistance.
Resistant to high power frequency and impact current, with stable resistance.
Connection materials include graphite connecting bolts, flexible graphite wires, galvanized flat steel, copper-plated flat steel, pure copper conductors, tinned copper and other materials. The welding method can be bolted connection, electric welding, hot melt welding, and the construction is simple and convenient.
The zero-ohm composite grounding body can be used as a vertical grounding body or a horizontal grounding body, which is flexible in use.

Construction technical description

Recommendations for effective deep well grounding: When urban hardened roads are difficult to excavate in large areas, deep well grounding should be carried out in accordance with the distance requirements of the building and residential lightning protection regulations. Construction should be carried out according to the depth of groundwater in a suitable place.
When there is no groundwater depth, the normal single point depth is 8-12 meters. If the appropriate grounding resistance is not reached, then Make another set for connection at the same time; the materials used for deep well grounding are: zero-ohm composite grounding bodies are connected end to end to form a vertical grounding body that reaches the bottom of the well.
The grounding bodies are connected with special connectors and lead wires.
The backfilling material is backfilled with high-purity graphite composite resistance-reducing materials or solid resistance-reducing materials to complete the implementation of the zero-ohm grounding system.

Application

Zero-ohm composite grounding body is suitable for places with poor soil environment and limited installation space.
It is widely used in power grounding, communication grounding, railway grounding, hospitals, ancient buildings, schools, real estate, gas stations, gas stations, military rapid grounding devices, explosive depots, refineries, factories, etc.
It is especially suitable for rapid grounding devices, etc.
