According to the Electrotechnical regulation of low voltage REBT, for a correct execution of the grounding of a building of houses or premises of public concurrence, it is necessary to install in the whole perimeter of the building a closed ring of rigid wire of bare copper. This ring will be connected to the set ground rods necessary to decrease the ground resistance that the driver may have all the connections must be carried out with exhotermic welding.

This method guarantees a high conductivity, as well as an exceptional galvanic corrosion resistance, being the system chosen by our installers, both for the housing and tertiary sector and for the railway and substations.
