Fire-Resistant Ground Cable 450/750V CU/PVC/FR/LSZH 1×6mm²
Essential Circuit Protection for Critical Infrastructure
Engineered for Life-Safety Applications
Our 6mm² fire-resistant ground cable yellow green wire provides reliable earth continuity in emergency scenarios, featuring specially formulated materials that maintain conductivity even under extreme fire conditions. The heavy-duty 6mm² tinned copper conductor delivers superior fault current capacity while meeting stringent fire safety regulations.
Fire-Survival Construction
✔ Ceramic-Forming PVC Insulation - Maintains insulation integrity at temperatures exceeding 950°C
✔ LSZH Outer Sheath - Limits smoke opacity to <30% (IEC 61034) with zero halogen emission (IEC 60754)
✔ Low-Fire-Spread Design - Meets IEC 60332-3 vertical flame test requirements
✔ Corrosion-Resistant Copper - Tinned conductor prevents oxidation in humid environments
Technical Specifications
• Conductor: Class 2 tinned copper (1×6mm²)
• Voltage Rating: 450/750V
• Temperature Range: -25°C to +70°C (emergency +160°C)
• Flame Resistance: 120+ minutes circuit integrity (EN 50200)
• Insulation Resistance: ≥100 MΩ·km at 20°C
Critical Applications
► Emergency generator grounding systems
► Fire pump electrical circuits
► Hospital life safety equipment
► Tunnel and metro emergency exits
► High-rise building protection systems
Compliance & Certifications
• IEC 60331 (Fire resistance)
• EN 50200 (PH120 classification)
• IEC 60502-1 (Construction standards)
• BS 7629-1 (Fire performance)
Why This Ground Cable?
Unlike standard grounding cables that fail during fires, our FR-LSZH design ensures:
1) Continuous earth path during emergencies
2) Non-collapsing ceramic insulation structure
3) Safe evacuation environment with minimal smoke
Installation Advantages
• Superior flexibility (bending radius 6×OD)
• Easy stripping with color-coded insulation
• Compatible with standard cable glands
Available with project-specific certifications including UL 2196 and Lloyd's Register approval.
Essential protection for when safety matters most - ensuring your ground connection survives the emergency.
