"Installation of earthing device" This atlas is suitable for general applications industry Construction and installation of protective earthing devices, working earthing, lightning protection earthing and earthing devices Anti-static grounding for civil buildings. Including various types of buried earth electrode installation (rod, tube, angle steel, strip type, plate type) (brick and wooden structure, reinforced concrete, powder coat, cable trench, door, expansion joint; through walls, etc.); installation of grounding blocks, terminals, detection points, etc. ; schematic diagrams of grounding types for different systems (TN, IT, TT, TN-S, TN-C-S, TN-C); -Static earthing installation; usefulization of an earth electrode with reduced resistance. The grounding conductor (ground wire) in atlas is divided into several types such as bolted connection, welded connection, connector connection and refractory mud welding connection, which can be directly selected by designers and construction personnel.
