Thebuildings, structures, substations, transmission lines, communication systems and electronic systems all need a good grounding system to provide a channel for the lightning current dispersing into the ground quickly. Only that can guarantee the safety of these systems and humans under the condition of lightning stroke and power system short circuits. However, imperfect grounding will cause damage of the buildings, structures, electrical and electronic systems, interruption of power supply and communication, and even human casualty accidents.

The design of the grounding system, resistance diminishing, the measurement of resistance and corrosion diagnosis of old grounding system are the four tough problems of grounding technical. Ethree solved all the four problems perfectly with the cooperation with international famous scholars and professional companies. The grounding technology of Ethree contains:

•  Analysis technology of the soil geological structure
• Precise design technology of grounding systems
• Decreasing the grounding resistance projects in high resistivity regions
• High efficiency grounding resistance reducing products and grounding connection pieces
• Variable frequency measure system of grounding resistance
• Corrosion diagnosis technology of grounding systems
• Advanced grounding analysis software package

Grounding modules

• The main composition of the low resistance grounding module is nonmetallic material; it consists of high conductive and high stable nonmetallic minerals and electrolyte. The power-frequency grounding resistance of the module is 40% lower than metal grounding electrode with the same size.

Technical characteristics: corrosion resistance, non-toxic, long service life, easy installation, ability of hygroscopic moisture, low grounding resistance (30% to 45% lower than metal grounding electrode with the same size). The grounding resistance will not increase after the impact of large current. There is no appearance of harden, embrittlement and fracture. The resistance changes little with the season; it can maintain long-term stability.

Application field Applicable to lightning proof grounding, electrostatic proof grounding, AC operational grounding, DC operational grounding, safety grounding of building and grounding for other purposes.

 

Grounding Electrodes (Rods)

• The surface is coated by copper, nickel or chrome, the corrosion resistance is strengthened. This kind of grounding electrode has high conductivity, easy installation, electrical continuity and other advantages.

Technical characteristics: This set of grounding electrodes use drawing bar as main material and fill special electrolytic ionic compounds and hygroscopic polymer materials inside it. With the active ion permeates into the soil near the electrode, the current disperse condition is improved thus the grounding resistance is reduced.

Application field Applicable to lightning proof grounding, electrostatic proof grounding, operation grounding and safety grounding. It can be used in the grounding systems in the urban regions, or in the indoor system and devices in the condition it’s inconvenient to build a grounding grid inside the building. It can also be used in clay, sandy soil and other kinds of soil. It’s a kind of good, fast, economical and practical grounding electrode.

 

ALG Anticorrosion Ion Grounding Electrode

• Grounding electrode with the best resistance reduction and current disperse characteristic, good corrosion resistance, high stability and longest service life.

Technical characteristics: Compared with the traditional grounding methods, it can release the lightning current and induced current to the soil more quickly, so the grounding effect is more apparent in worse soil conditions.

Application field It is ideal to be used in regions of high resistivity and urban regions with very dense buildings.

 

Copper bonded steel grounding rod

• Copper bonded steel grounding rod are made by molecularly bonding 99.9% pure copper onto a low carbon steel core, they are high resistant to corrosion and very high tensile strength, they can be driven by power hammer to great depths.

Technical characteristics： Unique manufacturing process, high resistant to corrosion, better electrical properties, easy installation, agreeable appearance and low permeability.

Application field It can be inserted 30 m deep into the ground and can be used in special occasions.

 

Zinc Bonded Steel Grounding Rod

• Zinc Bonded Steel Grounding Rods are mainly produced with steel and high purity zinc. It can offer a very high level of corrosion resistance.

Technical characteristics: High strength; great tensibility and high thermo-stability. Not only meet the grounding requirements but also in the function of cathode protection.

Application field It is mainly used in petroleum, natural gas and other industries where cathodic protection is required.
