It is very easy to create high-quality grounding using
Each set includes all tools required to install a long-term grounding. The main element of any ZANDZ modular grounding set is a robust steel rod having a 250 mcm copper coating. Its protective coating thickness applied by an electrolytic deposition method allows increasing the earthing operating period from 30 to 100 years depending on the soil aggressiveness. Durable couplings made of a special brass type delivered with the set, and a clamp for connecting the grounding conductor are completely protected from soil corrosion. An additionally selected fitting allows simplifying the earthing system installation using a SDS-max perforating device.
You can install the earthing system not only in an open soil but also if you have minimum available space, e.g. in the basement or in a pit of the asphalted site. To provide convenient access to the top of the installed ground terminal, a ZANDZ inspection well is used which is designed for the load of 5,000 kg and harsh operating conditions.
In addition to the sets, flexible grounding conductors press-fitted with tips for convenient connection to the grounding bus in the electric panel can also be used. Their length varies from three to twenty meters. Several sets can be combined using a steel copper-plated bar 30 x 4 mm.
The composition of each set is provided in the table below.
