КВПВ (KVPV)

SCOPE AND PURPOSE

The cables are designed for connection to the electrical networks in a fixed position for voltage of 380, 450 and 660 V with alternating current frequency up to 400 Hz of water-submersible electric motors, long-term operating under the pressure of water of artesian wells up 7,09х10⁶ Pa (70 kgf/cm²).

The class of fire hazard of the cables according to GOST 31565 О2.8.2.5.4

STRUCTURE

Conductor

The conductors of cables should be multi-wired, flexible, round, made of copper and should meet the requirements of GOST 22483:

- for cables with cross section of conductor from 0,5 up to 4 mm² - 4 class of conductor;

- for cables with cross section of conductor from 6 up to 95 mm² - 3 class of conductor.

Insulation

Polyethylene composition

 (Color coded conductor, for single-core cables – white (uncolored) conductor)

Core arrangement

Insulated conductors of different colors, twisted in a cable core.

Over sheath

PVC-compound
