SMALL-SIZED CABLES, FLAME RETARDANT AT GROUP INSTALLATION, WITH LOW SMOKE- AND GAS EMISSION (modification – “flame retardant – Low Smoke”)

SCOPE AND PURPOSE

The cables are designed for transmission and distribution of nominal electric energy and electric signals in stationary electric installations on alternating voltage 0,5 and 1 kV and frequency not more than 50 Hz or correspondingly on direct voltage 0,75 and 1,5 kV

The cables are manufactured for general industrial use and nuclear power stations.

The cables don’t spread combustion at group installation.

The cables are designed for use in cable structures and premises, including objects which use nuclear power, in the systems of NPP of class 3 and 4 according to classification of НП-001–2015.

The class of fire hazard of the cables according to GOST 31565 – П1 б 8.2.2.2.

TECHNICAL DATA

Nominal voltage, not more than, kV 0,5; 1
Ambient temperature during cable operation, °С from - 50 to + 65
The ambient temperature for laying and installation of the cables (without preheat) is made, °C, not below -15
Minimum bending radius, diameters of cable 12
Reduction of light permeability in the test chamber not more than 50 %

CONSTRUCTION

Current-carrying conductor
Copper, multi-wire of circular form, of the 3 or 4 class according to GOST 22483.

Insulation
Polyethylene. Color or digital coded conductors.

Screen
For KMPEVng(A)-LS, KMPEVEng(A)-LS and KMPEVEVng(A)-LS insulated conductors are screened or screened in pairs with copper wires or by braiding with copper galvanized or non galvanized wires

Core arrangement and twisting
Insulated conductors, screened cores and screened pairs twisted in a cable core by concentric layer in different directions.

Taping
Of fiberglass tape or mica tape. It is allowed longitudinal wrapping.

Over sheath
PVC-compound of low fire hazard.

Overall screen
For KMPVEng(A)-LS, KMPEVng(A)-LS, KMPEVEng(A)-LS and KMPEVEVng(A)-LS is made by braiding with copper tinned or just copper wires.

Second over sheath
For cables KMPVEVng(A)-LS and KMPEVEVng(A)-LS is PVC-compound of low fire hazard.
