SMALL-SIZED CABLES FLAME RETARDANT AT GROUP INSTALLATION, WITH LOW SMOKE- AND GAS EMISSION (modification – “flame retardant – Fire-Resistant 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 nominal alternating voltage 0,5 and 1 kV and frequency up to 100 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 2 according to classification of НП-001–2015.
The climate modification is Moderately Cold Climate, categories of location 1– 5, according to GOST 15150–69.
The class of fire hazard of the cables according to GOST 31565 – П1 б 1.2.2.2.
TECHNICAL DATA

CONSTRUCTION
Current-carrying conductor
Copper, multi-wire of circular form, of the 3 or 4 class according to GOST 22483.
Thermal barrier
Taping with two mica tapes.
Insulation
XLPE (color or digital coded conductors).
Screen
For cables of types KMPvEVng(A)-FRLS, KMPvEVEng(A)-FRLS and KMPvEVEVng(A)- FRLS insulated conductors are screened or screened in pairs by braiding with copper galvanized or copper wires.
Core arrangement and twisting
Insulated conductors, screened cores and screened pairs are twisted in a cable core by concentric layer.
Taping
Of one fiber glass tape or mica tape
Inner sheath
PVC-compound of low fire hazard.
Overall screen
For cables of types KMPvVEng(A)-FRLS, KMPvEVEng(A)-FRLS and KMPvEVEVng(A)- FRLS is made in the form of braiding of copper, galvanized wires. For cables of types KMPvVEVng(A)-FRLS, KMPvEVEng(A)-FRLS and KMPvEVEVng(A)- FRLS a screen of copper wires is allowed.
Over sheath
PVC-compound of low fire hazard.
