КУПЭфПмнг(А)-FRHF (KUPEfPmng(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.

Fire resistance not less than 180 min.

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

The cables do not spread combustion at laying bunches of cables on category A

Cables are resistant to salt mist. 

Cables are resistant to dynamic dust. 

Cables keep working under the influence of earthquakes intensity of 9 points on the MSK.

STRUCTURE

Number of pairs in the cable

1; 2; 4; 8; 12; 16; 20; 32 and 40.

Current-carrying conductor

Copper, with the cross-sections 0.5 mm²

Thermal barrier

Taping with a mica tape.

Insulation

Halogen-free polymer composition.

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

Lapping with alum polymer tape and a copper galvanized wire superimposed longitudinally.

Over sheath

Halogen-free polymer composition. The color of over sheath is grey, for fire resistant cables – orange. It is allowed different color of the sheath by agreement with a customer.
