Profile is widely used in many areas of telecommunications, electricity, transport, finance, petrochemical, building systems, such as communication bureau (station), mobile base stations, scheduling Room, substations, highway facilities, computer rooms, intelligence community and other stringent requirements on the ground units and departments, the use of the systems can constitute good grounding system performance. Copper clad materials have good electrical properties, high mechanical strength, in particular the external covering of the copper layer having good corrosion resistance, it has been widely used in grounding devices. United States, Britain, Germany and other countries in the relevant standards are prescribed grounding, grounding wire can be made of copper-clad steel composite material. In China, anti-corrosion and reliability of the grounding device has drawn attention to the use of composite materials instead of copper-clad steel. 1 Classification 1 grounding rods, copper grounding rods: In the above external ground steel rod covered with a layer thickness 0.254mm copper layer, called copper grounding rods, also known as copper clad steel ground rods. 2, galvanized ground rods: outside the steel bars were galvanized embalmed. 3, graphite ground rod: made into graphite material rod grounding module. Grounding rods can be divided according to style double tongue grounding rod, single tongue style ground rod, screw ground rods, hand-ground rod, gun-type ground rod, separate ground rod and multi-angle type ground rods and so on. 2 hedgehog hedgehog helix spiral grounding rods grounding rods grounding rods to one spiral series, which compared with the traditional spiral flat ground rod or spiral hook with saving time, effort, easy to use convenient features. The head hedgehog spiral ground rod alloy aluminum die-casting. Club shafts made of high insulation performance, good mechanical strength, light weight, the high-quality color proof epoxy treatment tube processing, light weight, high mechanical strength insulation rod, portable and convenient. 3 Caution copper grounding rods and ground supporting the use, operation should be on the ground soft copper phase copper nose, eyes fixed on the ground rod grounding Clips (Continued Clips fixed and movable type) corresponding position monocular copper ground wire conjunction nose fixed to the ground on the folder or needle, constitute a complete grounding wire. The earth clamp or nail ground after the ground bar to hang onto busbar or line, when the removal of the grounding line, the program must first disconnect Clips, after the demolition earth clamp.
