ZZ-100-102МВ (vertical) electrolytic grounding kit

Kit  of electrolytic grounding 100-102MВ ZANDZ ZZ is intended for organization of a grounding device in high resistivity soils (from 300-500 ohms * m): permafrost, sand, rock without using of bulk ground.

This complete package contains all components, necessary for the installation of a ground conductor which are easily matched with each other.

Because of the special configuration it is recommended for use in oil and gas facilities in the Far North.

The electrode is mounted vertically in the prepared hole 6 meters deep.

 

Advantages  of electrolytic grounding

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

  • does not cause acceleration of electrode corrosion
  • does not completely turn into the electrolyte immediately when the soil is too moist (important in spring period)
  • It 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 ground resistance
  • the lifetime of the electrode is not less than 50 years

Mode of operation

ZZ-100-102МВ (vertical) electrolytic grounding kit
1. Maintenance pit
2. Special mixture of mineral salts
3. Near-electrode filler
4. Ground electrode

The main element of electrolytic grounding - hollow electrode (tube) with perforation holes along the entire length, 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). The exchange of liquids is carried out through the perforated surface of the electrode.
Traditional methods, described on a individual page are then for the basis of electrolytic grounding electrode: "Grounding in the permafrost".

Application features (talik formation)

Due to the reduction of soil freezing temperature, a talik zone is formed around the electrode, it may be dangerous to the basement of a nearby building or pavement. Talik area on the ground surface presents itself a circle around the electrode with a radius equal to the depth of the electrode.

Application features (talik formation)

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

Maintenance of electrolytic grounding

Maintenance of electrolytic grounding

Electrode maintenance is very simple. It requires periodic (every few years) opening of the electrode cover and visual examination 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 put into it.

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.

Components

Ground electrode

Ground electrode 1 piece
A stainless steel tube of 03H18N10 brand or similar with a diameter of 219 mm and a length of 6 meters with perforation holes of 2-3 mm in diameter along its length. To connect to a ground conductor a strip section of stainless steel brand 03H18N10 or similar with the dimensions 3 mm * 30 1 meter long, attached to the electrode body by welding, is used.

The mixture of mineral salts is supplied as a kit part in a separate pack.

Near-electrode filler

Near-electrode filler 360 kg
Soil substitute made of a mixture of graphite chips with a special kind of clay mineral is designed 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

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, measuring of its parameters.

Connecting conductor ( a band of black or stainless steel)

Connecting conductor ( a band of black or stainless steel) 25 meters
A band of 3 * 30 mm is used as a conductor to connect the grounding electrodes with each other into one electric network.
A stainless steel band posessess a very high corrosion resistivity due to the use of 03H18N10 steel grade (or equivalent) and its lifetime is not less than 50 years.
