Bentonite cement acts as a function of cement in general that is to glue, but the grounding system must use a special adhesive that is bentonite cement, because bentonite cement aims to reduce the resistance (resistivity), so the soil resistance becomes lower as determined by PLN for soil resistance at Grounding is recommended below 50 ohms.

One of the bentonite products is GEM 25A made by the ERICO brand. GEM 24A powder in one sack has a weight capacity of 11.34 kg and there is a hole in the top of the sack packaging so it is very easy to carry. For Net Wt GEM 25A which is 25 lb.

Erico Lightning Protection Distributor
Lightning rod is a series of paths that are used as a path for lightning to go into the ground, without damaging the objects through it. Our CV. Wijaya Lightning Protection Lightning as Distributor of Lightning Protection Erico explains that there are 3 main parts to the lightning rod: lightning rod, conductor wire, grounding. When the negative electric charge at the bottom of the cloud is fulfilled, the positive electric charge on the ground will be immediately attracted. The electric charge then immediately travels up through the conductor cable, towards the end of the lightning rod. When the negative electrical charge is close enough on the roof, the attraction between the two charges gets stronger, the positive charge at the ends of the lightning rod being pulled towards the negative charge.
