Grounding rod, also known as grounding electrode, grounding grid.Grounding rodis designed and manufactured on the theoretical basis of improving the internal conductivity of grounding conductor and reducing the external soil resistivity of grounding conductor. The product has the advantages of simple construction, small floor area, no environmental pollution, long service life and low resistance value.
It is widely used in many fields, such as communication bureau, mobile base station, dispatching machine room, substation, highway facilities, computer room, intelligent community and so on, which require strict grounding requirements. The system can be used to form a good grounding system. Copper-clad steel has been widely used in grounding devices because of its good electrical conductivity, high mechanical strength, especially the excellent corrosion resistance of copper coatings. The United States, Britain, Germany and other countries stipulate that copper clad steel composite material can be used in grounding body and grounding wire in relevant standards. In our country, the corrosion resistance and reliability of grounding device have been paid more and more attention, and copper clad steel composite material is used instead.
Classification of Ground Rod Wire
1. Copper plated steel wire
: Cover the outside of the grounding rod with a layer of copper over 0.254 mm thickness, which is called copper-plated grounding rod, also known as copper-clad steel grounding rod, etc.
2. Galvanized grounding rods
: hot-dip galvanizing and anticorrosive treatment on the outside of the steel rod;
3. Graphite ground
: PTD-1 type rod grounding module made of graphite material; according to different geological conditions, select the appropriate grounding rod.
