power electric cables

Assembly:
1. Conductor aluminum, single or multiwire, round- or sector-shaped, 1 and 2 class as per GOST 22483. 
2. Insulation PVC.
Insulated multiconductor cable conductors carry identification coloring. Nominal insulation thickness is equal to 3.4 mm.
3.Cables are only made of three conductors.
4. Twisting Insulated conductors are twisted.
5. Inner layer extruded from rubber compound while filling the gaps betwen conductors, for AVBbShvng cables extruded from flame retardant rubber compound. 
6. Girth insulation PVC with a minimum thickness of 0.9 mm. for AVBbShvng extruded from flame retardant PVC.
7. Conductive screen made by aplying a tape made from conductive rubbered fabric with a nominal thicknes of 0.3 mm with overlapping or two conductive cable paper tapes with a nominal thickness of 0.12 mm with a gap.
8. Metallic screen of two copper tapes or foil of minimum thickness of 0.06 mm with a gap.
9. Isolator two polyethleneterephtalate tapes, thermoset web or similar with overlapping. For AVBbShvng cables a flameretardant PVC isolator layer is applied over the taping.
10. Protective armoring BbShv type
- two steel armor tapes whereas the upper tape cover the gaps in between the turns of the lower one. 
- Protective jacket is from flameretardant PVC. For AVBbShvng cables is from a flameretardant PVC.


Application:
The cables are intended for transmitting and distributing electric power in fixed installations rated for nominal alternating current voltages of 6 KV 50 Hz. 
They are meant for burying (in trenches), indoors, in tunnels, ducts, mines (except for laying in assemblies) as well as outdoors if the cable is not exposed to considerable stretching effects while there is a risk of mechanical damages during its operation
