CABLES FOR CONTROL AND ALARM SYSTEMS, FLAME RETARDANT AT GROUP INSTALLATION AND NOT EMIT- TING COROSIVE ACTIVE GASEOUS PRODUCTS AT BURNING AND SMOULDERING (modification – “ng-HF”)
SCOPE AND PURPOSE
The cables are designed for transmission OF ELECTRIC SIGNALS and distribution of electric energy in control circuits, alarm, communications, and unit connections of voltage 250, 380 and 1000 V of alternating current of frequency up to 200 kHz or at voltage correspondingly 350, 750 and 1500 V of direct current.
The cables are manufactured for general industrial use and nuclear power stations at usage out of under containment zone of NPP of classes 2, 3 and 4.
The climate modification is – B, categories of location – 5, according to GOST 15150–69.
The class of fire hazard of the cables according to GOST 31565– 2012 П1 б 8.1.2.1 according to classification НП-001–2015.

CONSTRUCTION
Current-carrying conductor
Copper, multi-wire or single-wire. For KPEPng(A)-HF of the 1 class, for the rest ones of the 4 class according to GOST 22483–2012.
Insulation
Halogen-free polymer composition.
Twisting in pairs
For cables with pair twisting the insulated conductors are twisted in pairs.
Screen over conductor
For KUGEPPng(A)-HF; KUGEPPEng(A)-HF and KUGEPPEPng(A)-HF – a screen is braided with a copper galvanized wire over the insulated conductor or a pair of insulated conductors.
Separating layer
For KUGPEPng(A)-HF of halogen-free polymer composition. For the rest ones – taping with PET – E film.
Inner sheath
For KUGPPEPng(A)-HF and KUGEPPEPng(A)- HF – halogen-free polymer composition
Screen
For KPEPng(A)-HF, KGPEPng(A)-HF – a common screen in the form of foil, composite flexible material under the sheath, copper galvanized contact wire is laid under the screen. For KUGPPEPng(A)-HF and KUGEPPEPng(A)- HF – a common screen in the form of braid of copper galvanized wire. For KUGPEPng(A)-HF – a common screen in the form of braid of copper wire.
Over sheath
Halogen-free polymer composition.
Screen
For KUGPPEng(A)-HF and KUGEPPEn (A)-HF a common screen in the form of braid of copper galvanized wire over the sheath.
