- KUPPng(A)-HF,
- KUPplng(A)-HF
CABLES FOR MONITORING CIRCUITS, FLAME RETARDANT AT GROUP INSTALLATION NOT EMITTING COROSIVE ACTIVE GASEOUS PRODUCTS AT BURNING AND SMOULDERING (modification – “flame retardant – Halogen-Free”)
SCOPE AND PURPOSE
The cables are designed to transmit signals of up to 250VAC, 50 Hz or up to 350VDC/300mA when connecting detectors and actuators to SCADA hardware and software and to be used in the process areas outside the containment building of nuclear power stations, classes 3N, 3U, 4N and 4U as per NP-001 (rules and regulations).
Climate version B, siting category 5, atmosphere type IV (coastal industrial) as per GOST 15150
Zerohalogen, non corrosive gases: GOST IEC 60754-2
Fire retardant: GOST IEC 60332-3-22
Smoky density: GOST IEC 61034-2
The class of fire hazard of the cables according to GOST R 31565 P1b.8.1.2.1.

CONSTRUCTION
Number of pairs in the cable
2; 4; 8; 12; 16; 20; 32 and 40.
Current-carrying conductor
Copper or tin-plated copper, nominal diameter 0.8 mm (area 0.5 mm2).
Insulation
Halogen-free polymer composition. Color coded.
Core arrangement and twisting
Two insulated colour-coded strands are twisted into a pair. The pairs are twisted into elementary four-pair bundles, with elementary bundles twisted into a core.
Belt insulation
PET-E tapes wound (helically with overlap) over the twisted core (two- and four-pair cable) or elementary bundle.
Screen
Aluminium polymer tape wrapping (helically with overlap) and tin-plated copper contact wire.
Over sheath
Grey Halogen-free polymer composition.
The cables are designed to connect to equipment using Maxi-Termi-Point technology
Salt-resistant cables
Dust-resistant cables
The cables are unaffected by exposure to earthquakes up to MSK magnitude 9
