KUPPlng(A)-FRHF

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 2, 3 and 4 according to classification НП-001-97 (ОПБ-88/97).

The climate modification B, categories of location – 5, atmosphere type IV (coastal-industrial) according to GOST 15150-69.

The cables do not spread combustion at laying of cable bundles on category A.

The smoke formation at burning and smoldering of cables does not reduce the light transmission by more than 40% in accordance with GOST R IEC

Fire resistance of the cables is not less than 180 min.

The class of fire hazard of the cables according to GOST 31565 - П1б.1.1.2.1.

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.

STRUCTURE

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 grey color
