YXZ3Z1 (N2XFGBH) – Cu / XLPE / SWA / LSF
0.6/1 kV halogen free XLPE insulated steel wire armoured power cables
(YXZ3Z1 / N2XFGBH) are designed for power transmission and distribution in fixed
installations where enhanced mechanical protection, fire safety, and low smoke
emission are required.
These cables combine XLPE insulation with steel wire armouring and halogen free
sheathing materials, providing high mechanical strength, reliable electrical
performance, and minimal toxic gas emission in case of fire. They are ideal for
critical infrastructure and industrial applications.
Applications
- Power transmission and distribution networks
- Underground installations and direct burial
- Industrial plants and heavy-duty installations
- Infrastructure and utility projects
- Public buildings requiring enhanced fire safety
- Outdoor installations exposed to mechanical stress
Thanks to their steel wire armouring and halogen free construction, YXZ3Z1
(N2XFGBH) cables are suitable for installations where both mechanical protection
and fire safety are critical.
Cable Construction
- Conductor: Solid or stranded copper conductor
- Insulation: XLPE (Cross-Linked Polyethylene)
- Inner Sheath: Halogen free compound
- Armouring: Steel wire armour (SWA)
- Outer Sheath: Halogen free compound (LSF)
YXZ3Z1 (N2XFGBH) cables are constructed with XLPE insulated copper conductors,
protected by steel wire armouring and halogen free inner and outer sheaths. This
design provides excellent mechanical protection, improved thermal performance,
and low smoke and toxic gas emission during fire.
