Installation cables and wires

ВПП, ВППУ, ВПВ

DESIGNATION

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:

Model	Definition
ВПП	polyethylene insulated, in polyethylene sheath for the voltage of 380 and 660 V;
ВППУ	the same, for the voltage of 3000 V, with thickened insulation (only 25 and 35 mm² conductor areas);
ВПВ	polyethylene insulated, in PVC sheath for the voltage of 380 and 660 V.
