КПССнг(А)-FRLSLTx – (KPSSng(A)-FRLSLTx)

SCOPE AND PURPOSE

The cables are designed for single or group fixed laying in fire protection systems, fire alarm systems, in warning systems and evacuation management of people during fire, in buildings, constructions and structures with mass stay of people (industrial enterprises, schools, hospitals, office premises, railway stations and so on) where requirements for cables and wires to operate in fire conditions are demanded.

They are operated inside and outside the premises, provided protection from direct affect of solar radiation and precipitation.

The class of fire hazard of the cables according to GOST 31565 - П1б 1.2.1.2

Fire resistance of the cables, min, not less: 2400

Smoke generation in the test cell: not more than 40%

Test category on the flame retardance: А

Equivalent index of toxicity, g/m3 , more: 120

STRUCTURE

Current-carrying conductor

Copper, single-wire of the 1 class or multi-wire not less than of the 3 class according to GOST 22483, with the cross-sections from 0.2 to 2.5mm2

Insulation

Low-toxic, ceramic-forming, silicon rubber.

Core arrangement

Insulated conductors are twisted in a pair and must be color coded. The twisted pairs are situated in parallel in cables with two pairs.

Thermal barrier

It is an overlapping with one mica tape. A thermal barrier in two pair cables is overlapped on each pair individually.

Screen

Alum-polymer tape is superimposed by winding or longitudinally over the additional thermal barrier.

A contact conductor of copper, galvanized wire is laid under the screen.

Over sheath

Low toxic PVC compound of low fire hazard.
