Lightning Arrester Configuration In Grounding System Construction

As a core component of the lightning protection system, the design quality of the grounding grid directly affects the protective effectiveness of the 11kv lighting arrester price device. The layout of the grounding electrodes needs to be specifically planned based on factors such as soil resistivity and geological conditions.

When using galvanized angle steel as a vertical grounding electrode, L50×5 specification material with a length of 2.5 meters is typically selected and driven vertically into the soil at a distance of 1.5 to 3 meters from the building's exterior wall. Horizontal grounding electrodes use 40×4 galvanized flat steel, with each vertical grounding electrode welded together to form a closed loop. The grounding terminal of the 11kv lightning arreaster price should be connected to the grounding busbar via a copper core conductor of at least 16 square millimeters using the shortest path.

In the equipotential bonding stage, metal components such as the outer casing of the distribution box in the equipment room, the grounding terminal of the 11kv surge arrester, metal cable trays, and anti-static floor supports must all be reliably connected to the grounding grid via copper busbars or multi-strand copper conductors. Using a combined grounding method can eliminate potential differences between different grounding grids, preventing damage to the 120 kv lightning arrester due to potential backflash during lightning current discharge. The grounding lead wire should avoid sharp bends to maintain the continuity of the electrical path, and the grounding test point should be set in a location that is easy to test.
