To minimize the effect 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 current exposure to people who may be near production equipment in case of possible problems in the wiring. Such material is necessary as protection for various wires and cables that are in residential complexes. In addition, such a strip can be used to output voltage in pipelines. This helps to increase pipe longevity while reducing the effect of corrosion.
It is worth noting that a metal strip can be used to reduce the risk of electric shock and to relieve tension of natural origin. For this, a large 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 of occurrence of dangerous situations for humans. Therefore, in order to avoid troubles, a metal strip is used - this is a reliable tool that should be used when conducting electricity in homes and in industry. For the grounding device in the house, in addition to such a strip, it is necessary to purchase a power distribution board, an earthing switch, wires and electrical appliances.
In addition, the metal strip may not be used for grounding, if natural grounding conductors are made in the house for safety: water pipes, building frames (made of metal), but if they come in contact with the ground, as well as well pipes. When using such natural grounding conductors, it is necessary to derive a special tap, namely to lay a special grounding wire from the structure to the electrical panel bus. The branch is connected by 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 contour. At the site of this contour, the trench will take the form of a triangle, at each top of which it is necessary to drill wells to a depth of three meters. Then a strip of stainless steel or coated with zinc is laid, and steel rods become clogged. Then the whole 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 spots are coated with bitumen varnish to prevent corrosion.
And the last, if three-phase electricity is passed from the overhead power line to the house, then not only the ground strip is used, but also an additional means of protection - a zero conductor at the input to the power shield. This device must be connected to the ground loop. It is very convenient and economical in terms of money to draw a circuit exactly at the stage of laying the foundation or drainage system.
