It is used for connection to electric networks for voltage of 380 and 660 V AC with a frequency of 50 Hz of water-immersion electric motors that work for a long time in artesian wells under pressure up to 7.09 MPa (70 atm.). The wires withstand bending at an angle of 180 ° around the roller, whose diameter is equal to 10 nominal diameters of the wire.
VPP wire decoding:
- V- waterimmersion
- P - polyethyleneinsulation
- P - polyethylenesheath
Vein - copper wire of normal flexibility. Insulation - LDPE (high pressure polyethylene)
Shell - LDPE (high pressure polyethylene).
Servicelife - 6 years.
