0.6/1kV Fire Resistant Power Cable EN 60332-3-24 for Critical Infrastructure
Product Overview
Designed for life safety and critical power continuity, this 0.6/1kV Fire Resistant Power Cable ensures circuit integrity during a fire event. Rated for 0.6/1kV (U₀/U), this cable combines XLPE insulation for high thermal performance with steel wire armor (SWA) for mechanical protection. Crucially, it complies with EN 60332-3-24 Category C for vertical flame spread on bunched cables—meaning it limits flame propagation in cable trays, tunnels, or risers, preventing fire from spreading between floors or compartments .
Application Focus: Emergency lighting, fire alarm systems, smoke extraction fans, water pumps, and any safety-critical circuit in buildings, tunnels, power plants, data centers, airports, and mass transit systems
Why EN 60332-3-24 Cat.C Matters
| Feature | EN 60332-3-24 Cat.C Requirement | Our Cable Compliance |
|---|---|---|
| Test Standard | Vertical flame spread on bunched cables | ✅ BS EN IEC 60332-3-24:2018 |
| Non-metallic Volume | 1.5 liters per meter of cable sample | ✅ Compliant |
| Flame Application | 20 minutes propane burner | ✅ Tested & Certified |
| Pass Criteria | Charred length ≤ 2.5m above burner | ✅ Independent lab verified |
| Configuration | Touching (≤35mm²) / Spaced (>35mm²) | ✅ Per Annex A requirements |
Technical Construction (Layer-by-Layer)
1. Conductor:
Stranded annealed copper (Class 2 per IEC 60228). High conductivity with excellent current carrying capacity .
2. Fire Barrier (Circuit Integrity Layer):
Mica glass tape applied over the conductor. During a fire, mica insulates and maintains electrical continuity even after XLPE has burned away. This is what makes the cable "fire resistant" (circuit integrity) .
3. XLPE Insulation:
Cross-linked polyethylene provides:
Maximum conductor temperature: 90°C (normal operation)
Short-circuit temperature: 250°C
Low dielectric loss and excellent aging characteristics
4. Bedding/Inner Sheath:
PVC or HFFR (Halogen-Free Flame Retardant) extruded bedding protects insulation and provides a stable base for armor.
5. SWA (Steel Wire Armor):
Galvanized round steel wires applied helically. Provides:
Mechanical protection against impacts, crushing, and rodent attack
Suitable for direct burial and external mechanical forces
Can serve as a combined CPC (Circuit Protective Conductor)
6. Outer Sheath (Flame Retardant):
UV-stabilized flame retardant PVC (or optional HFFR/LSZH). Complies with EN 60332-3-24 Cat.C for flame spread limitation.
