Let's make a resistance of 2 ohms! ZANDZ customer testimonials

In regions with an average annual temperature below 5оC, soil resistivity values cause a lot of confusion among designers and electricians.
For example, how to get a grounding resistance of 2 ohms in the soil with 500 Ohm*m resistivity? Here's our answer!

Our company received testimonials about the installation of grounding in the city of Novy Urengoy. Sergey, the representative of Engineering Systems Company, said that during the construction of a three-storey pharmacy at Geoologorazvedchikov street, an issue of grounding system installation had arisen. In addition to a low average annual temperature in the region (-4.7o C), the situation is complicated by the soil with a resistivity higher than 500 Ohm * m. The use of standard grounding kits would not be feasible for such a task. For example, if ZZ-000-015 modular grounding kit is chosen, then more than 12 kits would be required to achieve the desired resistance values, which would increase the cost and amount of work manyfold. Furthermore, not every facility area allows setting a large number of electrodes, as an optimal spacing distance between them should not exceed the depth of the electrode.

electrolytic grounding

ZZ-100-102 electrolytic grounding is the solution to such problems. This is an L-shaped vertical steel electrode filled with a special mixture of mineral salts. Its design, composition, and operating principle allow you to save time and costs when making a grounding system.


After ZZ-100-102 kit was mounted, grounding resistance measurements were carried out showing excellent results of 2.2 Ohm! 

In the near future, a new marker on the map of installed facilities will appear showing the city of Novy Urengoy. Thank you, Sergey, for your feedback!
