La description:
The Earth Rod also known as ground pole or ground net, which is designed and manufactured based on the theory of improving internal conductivity of grounding conductor and decrease external soil resistivity of grounding conductor.
Advantages:
The Earth Rod has the advantages of simple construction, small occupation area, long service life, no environmental pollution and low resistance value,etc..
Application:
The earth system of good performance can be conducted by this system, as it is generally applied in the area of communication,electricity,traffic,finance,petrifaction and architectural system,such as communication station,mobile base station,dispatching room,substation,expressway facilities, computer room and intelligent community and other units and departments with strict requirements for grounding.
Matériel:
The Copper-clad steel material has been widely used in grounding devices due to its good electrical conductivity, high mechanical strength, especially the good corrosion resistance of copper coating.The United States, Britain, Germany and other countries in the relevant standards have stipulated that the grounding body, grounding wire can be used copper-clad steel composite materials.In China, the corrosion resistance and reliability of grounding device have been paid more and more attention.
Types:
Copper-Bonded Earth Rod: the external layer of copper with a thickness of 0.254mm or more is called copper-plated grounding rod, or copper-coated steel grounding rod, etc.
Galvanized grounding rod: heat galvanizing anti-corrosion treatment is made on the outside of the steel rod;
Graphite grounding rod: type pTD-1 bar-like grounding module made of graphite material;
Choose suitable grounding rod according to different geological conditions.
