How To Standardize The Installation Of Grounding Wire?
Grounding cable as a safety return line, can be in the case of equipment leakage will be the current conductor to the ground or even underground, to prevent the body from receiving current damage, the standard installation of this grounding cable buried is essential. In this regard, we at Sichuan Sunlight Intelligent Co., Ltd. would like to explain the method of burying the grounding cable and the depth of burying.
Burial depth of the grounding cable
First of all, it is worth noting that the horizontal grounding material should be buried under the permafrost layer, because when the soil of the permafrost layer freezes its resistivity will rise linearly, generally consider the thickness of the permafrost layer 0.8m (according to the local situation). And the vertical grounding material should be buried vertically under the horizontal grounding material.
Although there are not many requirements for grounding conductors, one of the methods can meet the grounding requirements in a small area.
The method of burying the grounding cable
First of all, you should find a piece of natural soil ground, clean off the surface of the miscellaneous soil to expose the soil layer, and dig a 2-meter square operation pit downward. And according to the specification requirements, the grounding body should be buried at a distance of 0.8m below the surface, and according to the different soil conductivity around the appropriate adjustment to deepen. Then take a piece of angle iron or similar iron of about 1m, and grind the head into the ground vertically. Leave about 2cm for welding grounding terminal. Then make a section of about 30cm galvanized flat iron, drill the terminal installation holes and then do reliable welding with the grounding body. And its welding area should not be less than 10 square millimeters. The next step is to remove the welding slag and do anti-corrosion treatment on the welding mouth. Finally, the grounding bus and galvanized flat iron according to the requirements of a good and reliable connection after filling the soil and tamped. After doing so, a simple grounding cable is installed.
The above is about the burial method of grounding cable and buried depth of the introduction. If you have any questions, you can consult with Sichuan Sunlight Intelligent Co.
