CONTROL CABLES, FLAME RETARDANT AT GROUP INSTALLATION AND NOT EMITTING COROSIVE ACTIVE GASEOUS PRODUCTS AT BURNING AND SMOULDERING (modification “flame retardant – Halogen-Free”)

SCOPE AND PURPOSE

The cables are designed for transmission and distribution of nominal electric power and electric signals at the stationary installation on the nominal alternating voltage 660 V of nominal frequency up to 100 Hz including for use in NPP systems of class 3H according to classification НП-001–2015.

The cables of types KPBPng(A)-HF are designed for installation in premises and cable structures in case of danger of mechanic damage at operation.

The cables are recommended, especially for use at nuclear power stations, large thermal power stations, petrochemical objects, in the subway, on ships; buildings with mass stay of people: concert halls and indoor stadiums, theatres, airports and railway stations; in premises, equipped with computer and microprocessor appliances and other objects which have increased requirements for fire safety.

The class of fire hazard of the cables according to GOST 31565 П1 б.8.1.2.1.

STRUCTURE

Conductor
Copper, single-wire, of the 1 class according to GOST 22483, with the cross-section from 1 to 6 mm2.

Insulation
Halogen-free polymer composition.

Core arrangement
From 4 to 52 insulated conductors. The insulated conductors of the cables are twisted. Control cables have distinctive markings of insulated conductors (digital or color).

Inner sheath
Halogen-free polymer composition.

Screen
For cables of types KPPGЕng(A)-HF is made in the form of taping with the foiled flexible alumoflex with the contact conductor or with a copper tin-coated wire or in the form of copper tape winding.

Cable armoring
For cables of types KPBPng(A)-HF is laid helically with two steel, galvanized tapes.

Over sheath or jacket
Of halogen-free polymer composition.
