NHXH FE180
Halogen-free fire-resistant power cable, 0.6/1 kV, FE180 E30–E90
NHXH FE180 is the fire-resistant power cable for emergency supply: a mica tape beneath XLPE maintains circuit integrity for 180 minutes (FE180), halogen-free and low-smoke. For lifts, smoke extraction and fire pumps. Supplied to order; the lead time is stated in the quote.
NHXH FE180 is a halogen-free, fire-resistant power and installation cable for safety and emergency circuits that must keep operating during a fire, such as emergency lighting, smoke-extraction and sprinkler systems, fire pumps, alarms and other life-safety supplies. A mica-glass fire-barrier tape applied over the conductors and halogen-free cross-linked (XLPE) insulation together maintain circuit integrity to FE180 (IEC 60331), while the complete cable achieves system integrity classes E30 to E90 to DIN 4102-12 depending on the mounting. The low smoke zero halogen (LSZH) sheath is orange for easy identification and, when burning, emits low smoke and no corrosive halogen gases so that escape routes stay passable and equipment is protected. It is available as single-core and multicore cables, rated 0.6/1 kV.

Applications
- Supply to emergency systems: lifts, smoke extraction and sprinkler pumps.
- Safety installations where the circuit must keep working during a fire.
What to look out for
- The E class (E30–E90) depends on the approved mounting system.
- For fire-resistant signal/bus circuits choose JE-H(St)H Bd FE180.
- CPR class Eca. Where the cable is exposed to indoor air in a building, the Bbl requires at least Dca; choose the B2ca version there, on request.
- Conductor
- Plain (bare) annealed copper, solid class 1 or stranded class 2 acc. to IEC 60228 / VDE 0295.
- Fire barrier
- Mica-glass fire-resistant tape applied over the conductor(s); the fire barrier that maintains insulation integrity under flame (FE180).
- Insulation
- Halogen-free cross-linked polyethylene (HX / XLPE).
- Sheath
- Halogen-free, flame-retardant, low-smoke (LSZH) polyolefin compound; orange (other colours on request).
- Core identification
- Acc. to VDE 0293-308; green/yellow earth core in the standard 'J' versions; multicore control versions numbered.
- Rated voltage Uo/U
- 0.6/1 kV (600/1000 V).
- Fire resistance (circuit integrity)
- FE180 acc. to IEC 60331 (insulation integrity maintained 180 min under flame).
- System integrity
- E30 to E90 acc. to DIN 4102-12 (30 to 90 min functional integrity of the installed circuit, depending on the mounting system).
- Reaction to fire (CPR)
- Eca (EN 50575); B2ca-s1a,d1,a1 on request.
- Standard
- VDE 0266 / HD 604 S1 (halogen-free 0.6/1 kV cables); conductors acc. to IEC 60228; fire tests IEC 60331 and DIN 4102-12.
- Flame-retardant
- Acc. to IEC 60332-1-2 (single cable) and IEC 60332-3-24 category C (bunched).
- Halogen-free / low smoke
- Halogen-free acc. to IEC 60754-1/-2 (corrosive gas); low smoke acc. to IEC 61034-1/-2.
- Max. conductor temperature
- +90 °C in normal operation (max. +250 °C for 5 s in short circuit).
- Min. bending radius, fixed
- 12 × outer diameter (multicore); 15 × outer diameter (single-core).
NHXH FE180 or N2XH?
NHXH FE180
- mica-glass tape, circuit integrity
N2XH
- flame-retardant, no circuit integrity
Both are halogen-free 0.6/1 kV cables with XLPE insulation. N2XH is flame-retardant but gives no circuit integrity. NHXH FE180 has a mica-glass tape around the conductors, which keeps the cores apart when the insulation burns away, so the circuit keeps working. Choose NHXH FE180 for circuits that must keep working in a fire, such as lifts, smoke extraction, sprinkler pumps and emergency lighting, and N2XH for the other supplies in the same building.

NHXH FE180
- IEC 60331
- the cable alone
- 180 minutes in the flame
E90
- DIN 4102-12
- cable plus fixings
- 90 minutes circuit integrity
FE180 concerns the cable alone: to IEC 60331 the circuit keeps working for 180 minutes with the cable in the flame. E30 to E90 to DIN 4102-12 concerns the installed circuit, so cable plus fixings, and gives 30 to 90 minutes of circuit integrity. FE180 on the cable therefore does not mean the installation achieves E90. If the specification asks for E90, cable and mounting system must have been tested together as E90.
