HF / LSZH
Halogen-free power cable with copper conductors and XLPE insulation
PvPGng(A)-HF is a power cable with copper conductors, cross-linked polyethylene (XLPE) insulation and a sheath of halogen-free polymer compound (HF / LSZH – Low Smoke Zero Halogen). It is used where halogen-containing materials are prohibited: metro systems, tunnels, data centres, nuclear power plants and marine facilities. When burning, it releases no corrosive gases or acrid smoke. Designation breakdown: Pv – XLPE insulation, P – polymer (halogen-free) sheath, G – unarmoured, HF – Halogen-Free.
Sizes with technical specifications. The electrical parameters (current, resistance) are identical to PvVG thanks to the XLPE insulation; the geometry is similar, with a slightly larger Ø due to the different density of the halogen-free sheath.

PvPGng(A)-HF (HF – Halogen-Free, or LSZH – Low Smoke Zero Halogen) is a modern halogen-free power cable for critical facilities. Its main difference from PvVG is that the sheath is made not of PVC (which contains chlorine) but of a halogen-free polymer compound (polyolefins, magnesium hydroxide, etc.).
In a fire, ordinary PVC releases hydrogen chloride (HCl) – an acrid, toxic gas that forms hydrochloric acid on contact with moisture. This corrodes electronics, equipment and building structures, while the toxic gases hamper evacuation. A halogen-free cable is free of these drawbacks: when burning, it releases no corrosive gases, and smoke emission is substantially reduced.
It is used in metro systems, data centres, server rooms, nuclear power plants, on marine vessels and in high-tech manufacturing – wherever there are electronics, optics or large numbers of people in enclosed spaces.
Conductors
Stranded copper, round or sector-shaped, 1–5 cores.
Insulation
Halogen-free cross-linked polyethylene (XLPE). Withstands continuous heating up to +90°C.
Stranding
The insulated cores are stranded together into a cable core.
Sheath
Halogen-free polymer compound (HF – Halogen-Free, LSZH – Low Smoke Zero Halogen). When burning, it releases no corrosive gases or acrid smoke.
