The grounding rod, also known as the grounding electrode or grounding grid, as the name suggests, is a metal rod inserted into the ground. Its purpose is to improve the internal conductivity of the grounding conductor and reduce the external soil resistivity of the grounding conductor. It is widely used in various industries such as communication, power, transportation, finance, petrochemical, and construction, and because the grounding rod is inserted underground, in order to reduce the resistance value and extend its lifespan, According to different geological conditions, grounding rods can be divided into three categories: copper plated grounding rods, galvanized grounding rods, and graphite grounding rods. Different types of grounding rods need to be selectively used according to geological needs in order to fully exert their true function
