Modular grounding

Modular grounding is designed for the installation of grounding devices (the grounds) at residential buildings (houses or cottages), mobile and fixed telecom operators or energy facilities, as well as industrial enterprises.

Such ground is an assembled structure consisting of interconnected steel rods having a length of 1.5 meters covered with a layer of copper.

Modular grounding advantages

The advantages of modular rod design are:
the ease of elecrode installation up to a depth of 30 meterswithout the use of special machinery or tools. All operations are carried out by one person. A greater depth means a very effective grounding.
Small area occupied by the grounding devices allows to install them in the basements of houses or near the walls just as one spot. The compact size minimizes earthwork volumes.

All parts are connected without welding *
The commercial-scale production of the parts means the following:
excellent corrosion resistance of all parts, resulting in the service life of up to 100 years.
full resistance of copper-bonded rods to mechanical damage (e.g., bending and bond liftoff) during installation, which allows carrying out installation works in soils containing gravel or small particles of construction debris

(thanks to the technology of electrolytic deposition of copper to steel).

^{* Connecting grounding device parts NOT made of ferrous metal is allowed by Technical memo 11/2006 of RosElectroMontazh Association (document link)}

Grounding kits

Various ready-made components of ZANDZ modular grounding kits with required specifications (e.g. to acheive a required value of grounding resistance). Such kits include all the parts necessary for the installation of a grounidng rod.

All components are easily connected to each other.

Such off-the-shelf kits are manufactured in five varieties that differ in the total length of rods, designation and contents:

ZZ-000-015 -	A universal ground for the installation as a modular electrode: one device for a depth of 15 m or three devices for a depth 5 m each (4.5+ 4.5+6 m). It is used as a ground with a low spreading resistance and as a lightning protection ground at a certain facility.
ZZ-000-030 -	Universal grounding device for the installation as a modular electrode: one electrode for a depth of 30 m or three electrodes for a depth of 10 meters each (10.5+10.5+9 m). It is used as a grounding device with a very low spreading resistance and as a lightning protection device.
ZZ-000-045 -	A multi-electrode ground consisting of 15 assembled ground electrodes for a depth of 3 m each. This is used as a distributed ground with a low touch voltage.
ZZ-000-424 -	A ground for the installation at containerized telecom and energy supply facilities (4 assembled electrodes 6 m each).
ZZ-000-636 -	A ground for the installation at containerized telecom and energy supply facilities (4 assembled electrodes having a length of 6 m each).

Deep ground (ZZ-000-015 and ZZ-000-030 kits)	Traditional ground (ZZ-000-045 kit)	Special ground (ZZ-000-424 and ZZ-000-636 kits)

A small number of vertical electrodes installed at a great depth	A large number of vertical electrodes installed at a shallow depth	Installation of grounding for containerized facilities
