Improves electrical resistance in rocky soils
Earth grids and plates are used for earth electrodees applications. They are used to dissipate the fault current through the contact made with ground. The dissipation of the fault current depends on the characteristics of the soil where the earthin electrodee is buried. The nature, humidity level, granulation are all factors that influence the resistivity of the ground. The ground resistance is improved by using one or more grounding grids or plates. In contrast to earth rods which offers a vertical penetration into the ground, the earth grids or plates offer a horizontal penetration and are commonly used in rocky soils that do not allow deep sinking. Meanwhile, the earth conductor is connected to the earth grid or plate using either exothermic welding or mechanical connections.
MALTEP offers a full range of earth grids with or without connecting strip, with a strap cross section of 3x3mm and featuring a 115x55 mesh as standard. The copper plates are 2, 3 or 4mm thick.
MALTEP also manufacture specific earth grids or plates upon request and pre-equipped with cables or tapes conductors welded in our factory. Do not hesitate to consult us for any particular request.
