To find out the cost of the cable, send the order code to our managers.
Delivery is carried out as soon as possible after the order is placed.
Cables of the AKVVG (unarmored), AKVVG-E (with overall shielding), AKVBbShv (with tape armor), and AKVKbShv (with steel wire armor) brands are intended for fixed connection to electrical devices, equipment, and terminal assemblies of electrical distribution systems with a nominal AC voltage of up to 660 V at a frequency of up to 100 Hz or a DC voltage of up to 1000 V.
Cables can be used for single installation in indoor spaces, ducts, tunnels, and in the ground (trenches), including aggressive environments and areas exposed to stray currents, if the cable is subjected to significant tensile forces. They can also be used for group installation in indoor spaces, ducts, tunnels, and in the ground (trenches), as well as in fire protection systems, provided that the cable is not exposed to significant tensile forces and there is a risk of mechanical damage during operation. If the cable has steel wire armor, it can withstand significant tensile forces.
| Nominal Core Cross-Section, mm² | Number of Cores |
| 2.5 | 4; 5; 7; 10; 14; 19; 27; 37 |

Aluminum single-wire conductive core of round shape, class 1 according to GOST 22483.
The insulation of the cores can be made of the following materials:
— «V» – polyvinyl chloride (PVC) compound, including low-flammability and low-fire-hazard types;
— «P» – polyethylene compound;
— «Pv» – cross-linked polyethylene compound.
The marking of insulated cores can be either color-coded or numerical (with a maximum spacing of 35 mm between numbers). Cables that do not have the letter «C» in their designation must have a counting pair in each layer, with insulated cores that differ in color from each other and from the other cores. Color coding must be either solid or in the form of longitudinal stripes at least 1 mm wide.
The insulated cores must be twisted into a common bundle. It is allowed to manufacture two-core, three-core, and four-core cables in a flat design («-P»).
A polyethylene terephthalate (PET) tape must be applied over the twisted cores of all cable types. The manufacture of cables without this tape is permitted, provided that the mobility of the cores is maintained and the sheath can be easily separated from the insulation during cable stripping.
Screening and protective armor:
— «E» – screen in the form of aluminum or copper foil wrapping;
— «Bb» – cushion insulation and armor made of two steel tapes;
— «Kb» – cushion insulation and armor made of steel wires.
A protective outer sheath («Shv» or «Shp») is applied over the armor, depending on the cable sheath material.
