- KUPPng(A)-FRHF,
- KUPplng(A)-FRHF
CABLES FOR MONITORING CIRCUITS, FLAME RETARDANT AT GROUP INSTALLATION NOT EMITTING COROSIVE ACTIVE GAS- EOUS PRODUCTS AT BURNING AND SMOULDERING (modification – “flame retardant – Fire-Resistant Halogen-Free”)
SCOPE AND PURPOSE
The cables are designed for transmission of signals with the operational voltage up to 250V of alternating voltage of frequency 50 Hz or of voltage up to 350V of direct voltage to 300mA in communication systems and fire protection systems for general industrial use, including buildings and structures of subway and for connection of transducers and actuators to software and hardware tools of APCS for laying inside the main process of the NPP, for operation outside the containment of nuclear power plants of class 2N, 2U, 3N, 3U and 4U according to classification NP-001.
The climate modification B, categories of location – 5, atmosphere type IV (coastal-industrial) according to GOST 15150.
Zerohalogen, non corrosive gases: GOST IEC 60754-2

CONSTRUCTION
Number of pairs in the cable
1; 2; 4; 8; 12; 16; 20; 32 and 40.
Current-carrying conductor
Copper, or copper galvanized with the nominal diameter 0,8 mm (with cross-sections 0,5 mm2).
Thermal barrier
Taping with one mica tape.
Insulation
Halogen-free polymer composition. Color coded.
Core arrangement and twisting
Two insulated conductors with the general coloring of different colors are twisted in a pair. The pairs are twisted in basic four-pair bundles, the basic bundles are twisted in a cable core.
Belt insulation
Spiral overlapping with PET-E tapes.
Screen
Overlapping with alum polymer tape and a copper galvanized wire spiral longitudinally.
Over sheath
Halogen-free polymer composition of orange color.
The cables are resistant to salt mist
The cables are resistant to dynamic dust
The cables remain functional when subjected to earthquake intensity of 9 points on MSK
