КВВ (KVV)

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 cables are used for single installation in cable structures and industrial premises. The group installation should be allowed only in the outdoor electric settings with temporary presence of service personnel, while passive fire protection is used. 

The class of fire hazard of the cables according to GOST 31565 О1.8.2.5.4

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

PVC-compound

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

Core arrangement (Except for cables of flat modification)

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

Over sheath

PVC-compound
