As a safety loop wire, the earth ground wire can lead the current to the ground or even underground in the case of equipment leakage, so as to prevent the equipment from being damaged by the current. The standard installation and burying of the earth ground wire is very important. Let's explain the earth burying method and depth of ground wire:


The horizontal grounding material is buried below the frozen soil layer, because the resistivity of the soil will rise linearly when the soil freezes. Generally, it is considered that the frozen layer is 0.8m thick (according to local conditions), and the vertical grounding material is buried vertically below the horizontal grounding material.


Although there are many requirements for the grounding body, there is a method that can meet the grounding requirements in a small area.


Find a piece of natural soil ground, clean up the exposed soil layer of surface clutter, and dig down a 2-meter square operation pit. The code requires that the grounding body should be buried below 0.8 meters from the ground surface. It can be deepened appropriately according to the different soil conductivity in different places. Take a 1 meter angle iron or similar iron tool, sharpen the head and drive it into the ground vertically. Leave about 2cm for soldering the ground terminal. Then make a section of about 30cm of galvanized flat iron, drill the terminal mounting holes, and then do reliable welding with the grounding body. The welding area should not be less than 10 square millimeters. The next step is to remove welding slag and do anti-corrosion treatment on the welded joint. Finally, make a reliable connection between the grounding bus and the galvanized flat iron as required, and then backfill and compact it. The simplest earth ground wire is ready.


The above is an introduction to the burying method and depth of the earth ground wire. I hope it will be helpful to you. If you have any other questions about the earth ground wire, please contact us for more information.
