ПвБПнг(А)-FRHF (PvBPng(A)-FRHF) – Russian analogue of N2XBH FE180/E90 MICA, PRAFla® SXP
SCOPE AND PURPOSE
The cables are designed for transmission and distribution of electric power in the fixed networks on the nominal alternating voltage 0.66 and 1kV and nominal frequency 50 Hz.
The cables are used for group installation of cable power lines of safety systems, wiring circuits of fire safety, (the wiring circuits of systems of fire alarm, power of pumps of fire suppression, illuminations of emergency exits and escape routes, smoke removal systems and ventilation, evacuation lifts).
For wiring in the surgical departments of hospitals, of the wiring circuits of emergency power supply of the equipment (current collectors), functioning in case of fire. It keeps working in case of fire during 180 (FE180) or 240 (FE240) minutes.
The class of fire hazard of the cables according to GOST 31565 П1б.18.104.22.168.
Copper, single-wire or multi-wire core, of circular or sector-shaped form, of the 1 or 2 class according to GOST 22483 with the cross-section from 1.5 to 1000mm2.
Thermal barrier for CCC (current-carrying conductor)
The overlapping with two mica tapes.
Insulated conductors of 2, 3, 4 and 5 core cables are twisted in a cable core.
Halogen-free polymer composition.
Lapped with mica or fiber glass tapes.
Additional thermal barrier (for “FE240”)
Taped with fiber glass mica tapes.
For cables of types PvBPng-FRHF is laid helically with two steel, galvanized tapes over the thermal barrier.
Over sheath or jacket
Of halogen-free polymer composition.
