| Conductor | Copper or aluminum, single-wire or multi-wire core, of circular or sector-shaped form, of the 1 or 2 class according to GOST 22483. |
| Insulation | PVC-compound (color coded conductor) |
| Core arrangement | Insulated conductors of three-core cables are twisted in a cable core |
| Inner sheath | It is made by extrusion with PVC-compound or chalk-filled non-cured rubber with the filling of outer gaps between insulated conductors. It is possible to fill the outer gaps between circular insulated cores with the bundles of non hygroscopic fiber or polymer materials with the lapping of fastening tape, on the top of which the expressional inner sheath is laid. It is allowed to wrap the cable core with the layer of tapes of polymer material, compatible with the materials of insulation and over sheath. |
| Taping | It is made of tape or tapes of conductive paper or conductive, synthetic tape or of tapes of non-woven fabric. |
| Screen | Is made of copper wires and a spirally imposed copper tape. It is allowed the taping of the screen with copper tapes. |
| Separating layer | Of polymer tape or non-woven fabric. |
| Bedding | For types VBV, АVBV is made of PVC-compound. |
| Cable armoring | It is laid helically with two steel, galvanized tapes. It is possible to overlap or longitudinally with PET or polypropylene tape. |
| Over sheath | PVC-compound. |
The cables are designed for transmission and distribution of electric power at the stationary installation on the nominal alternating voltage 6 kV of frequency 50 Hz for networks with the earthed and insulated neutral.
They can be laid in dry soils (sand, sandy-clay and normal soil with a moisture content of 14%).
Technical Data:| Nominal voltage, kV | 6 | |
| Ambient temperature during cable operation, °С | from - 50 to + 50 | |
| Minimum bending radius, diameters of cable | for multi-wire | 12 |
| for single-wire | 15 | |
| at installation with usage of a special template | 7,5 | |
| The cables are laid at temperature (without preheat), °С, not below | - 15 | |
