Electrolytic grounding

Electrolytic Grounding is intended for use in permafrost, stony or sandy soils with high resistivity (from 300-500 Ohm * m), without use of special equipment and made ground. On objects, where for some reason assembling of grounding electrodes to a depth of 1 meter is impossible, because the use of simple metal electrodes is inefficient due to a need to apply a large number of ground electrodes (up to 100).

Installation and calculation of this grounding is very simple. But that simplicity hides high-tech and modern solutions aimed only at the uncompromising quality of the result.

Advantages of electrolytic grounding

• electrolytic grounding electrode provides grounding resistance up to 12 times less than an ordinary steel electrode of the same size
• special mixture of mineral salts with a licensed additive:

• does not cause acceleration of electrode corrosion
• does not completely turn into an electrolyte immediately when the soil is too moist (important in spring period)
• makes the leach process uniform and constant. This contributes to not only preservation of electrolyte concentration in soil but its increase with time, which further contributes to the reduction of grounding resistance.
• the lifetime of the electrode is not less than 50 years
• small assembling depth of electrolytic grounding (0.7 m) makes such a ground electrodevery versatile to use, without worries about the impact of frozen ground on it (in particular, the effect of "pushing")

Mode of operation

1. Service pit
2. A special mixture of mineral salts
3. Grounding electrode
4. Near-electorde filler

The main element of electrolytic grounding - is a hollow electrode (pipe) |___ -shaped with perforations in the horizontal part mounted in the area of fire-setting of permafrost zone (To the depth of 0.7 meters) and filled with a special mixture of mineral salts. This mixture absorbs water from the environment, becoming an electrolyte (being leached) then penetrates into the ground, increasing its electrical conductivity (lowering its resistivity) and decreasing its freezing (lowering the freezing point). Exchange of liquids is carried out through the perforated surface of the electrode.

Traditional methods, described on an individual page, are taken for the basis of electrolytic grounding electrode: "Grounding in permafrost".

Application features (talik formation)

Due to the reduction of soil freezing temperature, a talik area is formed around the electrode, it may be dangerous for the basement of a nearby building or pavement. Talik area on the ground surface is an oval of about 3 x 6 m. 

It is necessary to take this feature into account when performing project works and distance the electrodes from objects that could be damaged.

ZZ-100-102 grounding kit

This type of grounding is represented by a ready-made kit ZZ-100-102, which contains all components required for mounting of the grounding electrode, which easily conjugate with each other.

Ground electrode
1 piece

Stainless steel tube in the form of letter “L” with perforation in the horizontal part. To connect the grounding conductor, a copper cable S> = 70 mm² or a tape of stainless steel S> = 90 mm², connected to the pipe is used. Overall length of the electrode = 3 meters.

Electrode in the kit ZZ-100-102 already filled with a special mixture of mineral salts.

Near-electrode filler
3 packs

Soil substitute made of a mixture of graphite chips with a special kind of clay mineral is intended to increase the area of electrical contact of the electrode with soil, as well as to ensure the uniformity of the leaching process.

Maintenance pit
1 piece

A plastic pit is designed for installation above the vertical part of the electrode (diving depth less than 50 cm).

Facilitates electrode maintenance and measuring of its parameters.

Clip for conductor's connection
1 piece (Completed only when using an electrode with a copper rope)

Stainless steel profiled clamp with M10 bolts. It allows to connect copper cable from the electrode to the grounding conductor - with a round wire or a tape (up to 40 mm wide).

Safe use of steel and galvanized wire is possible - for that purpose, there is a gasket inside the clamp, which prevents formation of galvanochemical connection between steel / zinc and copper.

To prevent loosening of threaded joints "bolt-nut" spring washers are used (Grover washers / grover washers) mounted between the clamping surface and the nut.

Hydro-isolation tape 1 piece (is packaged only at the use of the electrode with a copper wire)

1 piece (Completed only when using an electrode with a copper rope)

The tape is used to secure the connection (clip) from soil and electrochemical corrosion by means of complete dewatering (demoisturing) from the connection point, without which the corrosion process is impossible. The tape retains its physical and mechanical qualities for many years.

Made of non-woven synthetic fiber material, impregnated and coated with neutral composition based on a saturated oil hydrocarbon (petrolatum) and an inert silicon - containing filler. The tape remains soft under the influence of a wide range of temperatures. It does not harden or crack. The tape is highly resistant to mineral acids, alkali, salts and microorganisms, highly hermetical against water, steam and gas.

These pictures of products may differ from the real ones.

Individual electrode design (vertical)

The horizontal electrode structure is less labor-intensive at the assembling without the use of special equipment. At the accessiblity of driller on an object, is possible to produce electrodes of vertical design with the length / depth of 3, 6 and 9 meters.

Maintenance of electrolytic grounding

Electrode maintenance is very simple. It requires periodic (every few years) opening of the electrode cover and visual inspection of the volume of salt mixture inside it. When the mixture is completely transformed into the electrolyte, the electrode is filled with: a new volume of salt.

Nothing else is needed. Electrode filling is enough for a minimum service life - 10 years (on the average - 15 years). Therefore, the first inspection is not recommended before this date.
