APPLICATION
Installation wires are designed for connection to AC electric main on nominal voltage 380, 660 and 3000 V and frequency 50 Hz of electric motors operating in artesian wells for a long time. Operating pressure for ВПВ is 70 МPа at the ambient temperature from - 40°С to + 65 °С. Operational pressure for ВПП is the same at the ambient temperature from -40°С to +80 °С. Operational pressure for ВППУ is no more than 150 МPа at the temperature from -40°С to +80 °С.
ВПП
Installation wires for electric submersible motors with PE insulation and PE sheath on nominal voltage 380 and 660V.
ВППУ
The same, on nominal voltage 3000V with thickened insulation (only for cross-sections 25 mm2 and 35 mm2).
ВПВ
Installation wires for electric submersible motors with PE insulation and PVC sheath on nominal voltage 380 and 660V.
.
DESIGN
CONDUCTOR – copper, class 2 in accordance with ГОСТ 22483-77.
TECHNICAL DATA
Conductor DC resistance at 20°С corresponds to class 2 of GOST 22483.
Electric resistance of insulation at temperature 20 °С on 1 km of wire should not be less than:
1000 МОhm for wires on nominal voltage 380V;
2500 МОhm for wires on nominal voltage 660V;
3000 МОhm for wires on nominal voltage 3000V;
Wires should resist to high air pressure: for ВПП, ВПВ - 70 МPа, for ВППУ - 150 МPа.
Wires resist to high temperature: for ВПВ up to +65 °С, for ВПП, ВППУ up to +80 °С.
Wires resist to low temperature up to -40 °С.
Tensile strength of the sheath at elongation is not less than 12,50 МPa.
Service life is not less than 6 years.
