XLPE + ng-LS
Power cable with XLPE insulation and a low-flammability PVC sheath
PvVGng(A)-LS is a power cable with copper conductors, cross-linked polyethylene insulation and a low-fire-hazard PVC sheath (ng — does not propagate flame, category A) with low smoke and gas emission (LS — Low Smoke). It combines the higher current rating of XLPE with fire safety.
The geometry is identical to PvVG; the difference is in the composition of the outer-sheath PVC compound. Full range of cross-sections: 1.5 — 800 mm².

PvVGng(A)-LS is a modification of PvVG for facilities with stricter fire safety requirements, while retaining the advantages of XLPE. Cross-linked polyethylene insulation (with a thermal rating of +90°C) is combined with a sheath of low-fire-hazard, low-smoke PVC compound.
Used in places with large numbers of people: hospitals, schools, shopping malls, metro systems and high-rise buildings — wherever fire safety is required together with high currents. Low smoke emission maintains visibility on escape routes; for circuits that must keep operating during a fire, fire-resistant cables with the FR index are chosen.
Conductors
Stranded copper.
Insulation
Cross-linked polyethylene (XLPE), +90°C continuous.
Stranding
The insulated cores are laid up into a cable core, with tape wrapping where required.
Sheath
Low-fire-hazard PVC compound with low smoke and gas emission (LS).
