Armoured
Armoured power cable with copper conductors in a PVC sheath
VBShv — armoured power cable with copper conductors, PVC insulation, armour of two galvanised steel tapes and an outer PVC sheath. Intended for installation in the ground and under mechanical stress. Designation breakdown: V — PVC insulation, B — armour (two steel tapes), Shv — PVC sheath (outer sheath of PVC compound).
Sizes with actual technical specifications: outer diameter (with armour), weight, continuous current-carrying capacity in air at +25°C. Full range of cross-sections per GOST 31996-2012: 2.5 — 240 mm².

VBShv is the armoured version of VVG for installation in the ground and under mechanical stress. The construction includes armour of two galvanised steel tapes applied helically with a gap of no more than 50% of the tape width, and an outer sheath of PVC compound that protects the armour from corrosion.
Used for installation in trenches, cable tunnels and ducts in soils of low and medium corrosivity. The steel tape armour protects against mechanical damage and compressive loads. Suitable for 0.66/1 kV distribution networks of industrial and civil facilities.
Conductors
Stranded copper, round or sector-shaped.
Insulation
PVC compound with colour coding of the cores.
Stranding
The insulated cores are stranded into a core.
Inner sheath
Extruded PVC bedding under the armour.
Armour
Two galvanised steel tapes applied helically with a gap of no more than 50% of the tape width.
Protective sheath (outer sheath)
PVC compound, black – hence the “Shv” in the designation.
