Installation cables and wires
ВПП, ВППУ, ВПВ
Installation wire is designed for power line (rated voltage 380, 660 and 3000 V and 50 Hz frequency)connection of submersible electric motors long-working in artesian well waters under the pressure of:
- up to 70 MPa at ambient temperature from -40°С to +65°С (ВПВ model) and from -40°С to +80°С (ВПП model);
- not higher than 150 MPaat ambient temperature from -40°С to +80°С (ВППУmodel)
Wire models and their definitions shall correspond to the details given in the table below:
polyethylene insulated, in polyethylene sheath for the voltage of 380 and 660 V;
the same, for the voltage of 3000 V, with thickened insulation (only 25 and 35 mm² conductor areas);
polyethylene insulated, in PVC sheath for the voltage of 380 and 660 V.
SHEATH: polyethylene(ВПП, ВППУ), PVC (ВПВ).
Manufacturing ofВППandВППУmodels in single-layer insulating sheath of light-stabilized polyethylene is allowed.

Wires shall be resistant to the effect of high temperature:
- for ВПВ model - up to +65°С
- for ВПП, ВППУmodels - up to +80°С
Wires shall be resistant to the effect of high temperatureup to -40°С
Sheath ultimate tensile strength is not less than 12.50 MPa.
Wiring shall be performed at ambient temperature not lower than -15°С(ВПВ model) and -15°С (ВПП, ВППУmodel) withbend radius not less than ten wire diameters.
Operational life for ВПП, ВПВ models - not less than 6 years; for ВППУmodel- not less than 3 years.
