1、 Principle of reducing resistance:

High energy backfill material is composed of multiple components and is a good conductor. When used between the grounding body and soil, it can tightly contact the metal grounding body and form a sufficiently large current flow surface; On the other hand, it can infiltrate into the surrounding soil, forming a low resistance area with gentle changes around the grounding body, thereby reducing the resistance value of the grounding system.   

2、 Product usage scope:

High energy backfill material is widely used in various fields of the national economy, including power, communication, construction, broadcasting, television, transportation, national defense and military industry, metallurgy, mining, coal, petroleum, chemical, aerospace industries, as well as computer, satellite launch equipment, radar, navigation, ultra-high TV towers, highway monitoring equipment, signal devices for electrified railways, high-rise building towers, flammable and explosive devices, modern medical facilities, etc. It is used for safety (lightning protection, protection, anti-static shielding), grounding, and working grounding.

3、 Advantages of the product:

The effect of reducing resistance is significant, which can reduce the construction workload and reduce the need for grounding bodies. In particular, horizontal grounding bodies can be used instead of vertical grounding bodies that are difficult to construct (in mountainous and rocky areas, etc.). Convenient construction, can solve the difficulties of limited construction sites, can save a lot of metal materials, has long-term and stable performance, and good anti-corrosion performance. Less affected by climate. Good overall technical and economic feasibility, etc.

4、 Performance principle of high-energy backfill material:

1. High energy backfill material can slowly and persistently penetrate into nearby soil after absorbing water, improving soil composition and reducing soil resistivity near the grounding grid;

2. The main component of high-energy backfill material is high-quality volcanic rock, which has the dual properties of prolonging the service life of grounding electrodes, enhancing the conductivity and moisture retention between grounding electrodes and soil;

3. The resistivity ρ of high-energy backfill material products is ≤ 0.1 Ω m, and the △ R% of impulse current withstand test and power frequency current withstand test is ≤ 10%.

5、 Construction Guidelines

1. Dig a horizontal trench according to the design requirements, with a wide top and narrow bottom, and a flat bottom. As shown in the diagram on the right, the length of the trench shall be constructed according to the design requirements.

2. Place the straightened conductor in the middle of the groove and elevate it.

3. Pour the high-energy backfill material into a mixer or container and mix it in proportion to form a slightly thick paste.

4. Evenly and completely wrap the paste like high-energy backfill material around the grounding electrode and ground wire, which is the key to achieving excellent resistance reduction effect.

5. When the high-energy backfill material has not fully solidified, it must be covered with high-quality fine soil and compacted while backfilling.

6. According to the design requirements, drill a cylindrical hole for the vertical grounding body, place the grounding body in the center of the hole, and then inject high-energy backfill material into the circular hole
