Current-carrying conductor

Copper, multi-wire or single-wire.

For KPEPng(A)-FRHF of the 1 class, for the rest ones of the 4 class according to GOST 22483- 2012.

Thermal barrier for CCC (current-carrying conductor)

The lapping with two mica tapes.

Insulation

Halogen-free polymer composition.

Twisting in pairs.

For cables with pair twisting the insulated conductors are twisted in pairs.

Screen over conductor

For KUGЕРРng(A)-FRHF, KUGЕРРЕng(A)-FRHF, KUGЕРРЕРng(A)-FRHF a screen of copper galvanized wire over the insulated conductor or a pair of insulated conductors.

Core arrangement and twisting

Insulated conductors, screened conductors, pairs and screened pairs are twisted in a cable core.

Separating layer

For KUGPЕРng(A)-FRHF of halogen-free polymer composition.

For the rest ones – taping with PET–E film.

Inner sheath

For KUGPPЕРng(A)-FRHF and KUGЕРРЕРng(A)- FRHF- halogen-free polymer composition.

Screen

For KPEPng(A)-FRHF and KGPEPng(A)-FRHF – a common screen in the form of foil, composite flexible material under the sheath, copper galvanized contact wire is laid under the screen.

For KUGPPЕРng(A)-FRHF and KUGЕРРЕРng(A)- FRHF – a common screen in the form of braid of copper galvanized wire.

For KUGPЕРng(A)-FRHF - a common screen in the form of braid of copper wire.

Over sheath

Halogen-free polymer composition.

Screen

For KUGPPЕng(A)-FRHF and KUGЕРРЕng(A)- FRHF - a common screen in the form of braid of copper galvanized wire over the sheath.

The cables are designed for the transmission of electrical signals, and distribution of electric power to the control circuits, signaling, communications, interinstrument connections at a voltage of 250, 380 and 1000 V AC frequency of 200 kHz or voltage, respectively 350, 750 and 1500 V dc, and keeps working in case of fire.

Cables are manufactured for general industrial applications and nuclear power stations (AS) when operating outside the hermetic zone speakers.

Climatic version B, the category of placement 5 according to GOST 15150-69.

Fire resistance cables should be at least 180 minutes.

The class of fire hazard of the cables according to 31565-2012 П1б.1.1.2.1.
