FR + HF
Fire-resistant halogen-free power cable with a mica fire barrier
PPGng(A)-FRHF is a fire-resistant halogen-free power cable with copper conductors, a mica-based fire barrier, and insulation and sheath made of halogen-free polymer compounds. It combines three properties: FR – fire resistance (≥ 90 min at 750°C per GOST R 53316), ng(A) – flame-retardant (does not propagate flame), HF – halogen-free. For critical loads in places where halogen-containing materials are prohibited.
Sizes with technical specifications. The geometry is the same as VVGng(A)-FRLS; fire resistance is provided by the mica fire-barrier tape, and the absence of halogens by the composition of the insulation and sheath.

PPGng(A)-FRHF is a premium cable for the most critical loads: fire protection systems in metro systems, tunnels, data centres, nuclear power plants and on marine vessels. It combines three critically important properties:
It is used in smoke extraction and emergency lighting systems in metro systems; power supply to server equipment in critical data centres; fire protection systems of nuclear power plants and marine vessels.
Conductors
Stranded copper, 1–5 cores.
Fire barrier
Mica-based tape over each conductor. Maintains the cable's circuit integrity at 750°C for ≥ 90 minutes (GOST R 53316).
Insulation
Flame-retardant halogen-free polymer compound.
Stranding
The insulated cores are stranded together into a cable core.
Sheath
Halogen-free polymer compound (HF). When burning, it releases no corrosive gases.
