The resistance reducing agent is composed of multiple components, including fine graphite, bentonite, curing agent, lubricant, conductive cement, etc. It is a good electrical conductor. It is used between the grounding body and the soil. On the one hand, it can be in close contact with the metal grounding body to form a large enough current flow surface; on the other hand, it can penetrate into the surrounding soil and reduce the surrounding The soil resistivity forms a low resistance area with gentle changes around the grounding body.

Simply put, resistance reducers are generally used in places with high grounding resistance. We need to excavate one or more trenches to make ground nets. If the excavated soil is basically no resistance reducer, if it is dug out If it is stone, it is necessary to consider the use of resistance reducers.
