The Corrosion

Why think of caring for life and heritage must be sought a system that guarantees a good performance, with quality products and a proper installation. However not all grounding systems give these benefits and ensure good performance, since for example traditional systems have variable or controllable as the humidity or temperature, or some are of dubious quality even and its installation does not guarantee durability and effectiveness. Among the elements that are necessary for installation of grounding is the electrode, which is a piece of metal that must be in contact with the ground, currently there is a diversity of these variables in form and design, but it is important to know that everyone should be unchanged to the chemistry of the ground action and moisture to ensure a correct operationHowever not all systems of grounding system guarantees this. Let’s here some types of electrode used in ground facilities: the electrode in the physical-Rod lands: shaped cross, t or angle straight-Rehilete: two crossed and welded copper plates. -Plate: Must have an area of at least 2000cm squares and a thickness approx. 6.4 mm in materials-ferrous and 1.52 mm in materials non-ferrous-Star: this type of electrode gets a resistance value less.-mesh: forms armando a bonding of copper conductors bare-rings: resembles a bare copper spiral.-starry plate: it has the advantage of helping to dissipate the energy through their tips.-electrode rod of iron or steel: These rods must be at least 16 mm diameter-metallic tube electrode: the pipeline must be buried at least 3 meters and is indispensable to this other metal covered that will protect it from the corrosion-aluminum electrode: currently are not permitted – electrode embedded in concrete: this type of electrode must be on a buried Foundation – horizontal electrode: the most common form is the straight line, however their digging is very face-deep electrode: this type is mainly for very rocky terrain and a deep borehole until damp layers of the Earth occurs because humidity increases the conductivity-chemical electrode: consists of adding a chemical substance to the electrode to increase their conductivity.
