Description
The RZ1-K (AS+) fire-resistant power cable 0.6/1 kV has been specially developed to ensure the power supply of emergency and safety installations in case of fire. The cable retains its electrical functionality for long periods of time at high temperatures and is therefore ideally suited for public buildings and critical infrastructure.
Thanks to the supple, fine-stranded copper conductor and the halogen-free LSZH jacket, this cable combines high flexibility with maximum safety for people and the environment.
Key features:
- Flexible copper conductor, class 5
- XLPE insulation with mica tape
- Halogen-free LSZH outer jacket (low smoke)
- Rated voltage: 0.6/1 kV
- Maximum conductor temperature: 90°C
- Maximum short circuit temperature: 250°C
- Fire resistant up to PH120
- CPR response to fire: B2ca or Cca (depending on section)
- Low smoke generation, no corrosive gases
Fire safety and flexibility:
- Functional in fire up to 120 minutes
- Flame retardant and non-flammable
- Minimum bending radius: 5× cable diameter
These properties make the cable suitable for installations where operational reliability during fire and evacuation safety are essential.
Available versions:
Available in single and multi-core versions, with and without ground conductor, in a wide range of sections for low and medium power levels.
Typical applications:
- Emergency and safety lighting
- Fire detection and alarm systems
- Smoke and heat extraction systems
- Water pumps and emergency power supplies
- Public buildings, tunnels and infrastructure
