To minimize the impact of electric current, for example, during a lightning strike, a special metal strip is used: galvanized or stainless steel. It is also used as a specially adapted lightning rod for objects and to reduce the risk of electric shock to people who may be near production equipment in case of possible malfunctions in the electrical wiring. Such material is necessary as a protection for various wires and cables that are located in residential complexes. In addition, such a strip can be used to output voltage in pipelines. This helps increase the durability of the pipes while reducing the effects of corrosion.
It is worth noting that the metal strip can be used to reduce the risk of electric shock to a person and to relieve stress of natural origin. To do this, a large vicious circle is constructed from it, which is installed in the ground at a depth of 0.5 meters around the entire perimeter. Due to the coating of the metal strip with zinc or stainless steel, its service life is increased by 30-50 years.
When using electricity, there is always a high probability ofdangerous situations for humans. Therefore, in order to avoid trouble, a metal strip is used - this is a reliable tool that should be used when conducting electricity in homes and in industry. For a grounding device in a house, in addition to such a strip, it is necessary to purchase a power distribution panel, grounding conductor, wires and electrical appliances.
In addition, a metal strip may not be used for grounding if natural grounding conductors are installed in the house for safety: water pipes, building frames (made of metal), but if they are in contact with the ground, as well as well pipes. When using such natural grounding conductors, it is necessary to bring out a special outlet, namely, to lay a grounding special wire from the structure to the busbar of the electrical panel. The branch is attached with bolts or welding.
For the grounding device, you first need to dig a trench that will run from the object to the location of the special circuit. In place of this contour, the trench will take the form of a triangle, at each vertex of which it is necessary to drill wells to a depth of three meters. Then a strip of stainless steel or zinc coated is laid, and steel rods are also hammered. Then the entire structure is covered with a layer of excavated soil, in which there should be no debris and rubble. To reduce the resistance of the circuit, it is additionally attached to a metal fence or supports. Welding areas are covered with bituminous varnish to prevent corrosion.
And lastly, if three-phase electricity is supplied from the overhead power line to the house, then not only the ground strip is used, but also an additional means of protection - a neutral conductor at the input to the power shield. This device must be connected to a ground loop. It is very convenient and economical in terms of money to make a contour at the stage of laying the foundation or drainage system.
