Wires of the runway, VPV are intended for accession to electric networks on rated voltage to 660 V of alternating current with a frequency of 50 Hz of water submersible electric motors, is long the artesian wells working in water.
Test alternating voltage of 2,5 kV of the frequency of 50 Hz.
Electric resistance of isolation is not less than 250 megohms • km.
Radius of a bend of wires not less than 10 diameters of a wire.
Installation of wires is allowed to be made at an air temperature not below minus 40 °C (a runway brand wire) and minus 15 °C (a VPV brand wire).
Delivery of wires on reels of 10-14 type or in bays.
