Current-carrying conductor

Copper, with the cross-sections 0.5 mm²

Thermal barrier

For KUPPmng(A)-FRHF and KUPEfPmng(A)-FRHF 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

For cables of types KUPPmng(A)-HF and KUPPmng(A)-FRHF braiding with copper galvanized wires.

For cables of types KUPEfPmng(A)-HF and KUPEfPmng(A)-FRHF 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.

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).
