WDZ-YJV Fire Resistant Cable is a low-voltage power cable with cross-linked polyethylene (XLPE) insulation, designed to maintain circuit integrity in fire conditions. This cable features halogen-free, low-smoke, flame-retardant materials, making it ideal for use in environments where fire safety and low toxicity of combustion gases are critical. It ensures reliable power supply even during fire, which is essential for emergency systems, lighting, alarms, ventilation, and fire pumps.
Applications
WDZ-YJV fire-resistant cables are suitable for fixed power installations in:
Public buildings, commercial centers, hospitals, and tunnels
Power and switching stations, energy distribution networks
Industrial facilities and infrastructure projects
Indoor and outdoor environments, cable trays, ducts, and direct burial
Critical systems that must operate during fire, with minimal smoke and toxic gas emission
Standards
IEC 60228 – Conductors of insulated cables
IEC 60502-1 – Power cables with extruded insulation for rated voltages up to 1kV
BS 5467 – Thermosetting insulated armoured cables
IEC 60332-3 – Flame propagation
IEC 60754 & IEC 61034 – Halogen acid gas emission and smoke density
Construction
| Component | Description |
|---|---|
| Conductor | Plain or metal-coated copper/aluminium, Class 1 (solid), Class 2 (stranded), or Class 5 (flexible) per IEC 60228 |
| Insulation | Cross-linked polyethylene (XLPE), rated for 90°C continuous operation |
| Inner Covering | Extruded or lapped halogen-free material, compatible with the insulation; fillers are also halogen-free, suitable for fire-resistant construction |
| Armour | Optional: aluminum or galvanized steel wires, double steel tapes, or copper wires, applied helically over the bedding (IEC 60502-1) |
| Outer Sheath | Halogen-free, flame-retardant compound (ST8) as per IEC 60502-1; alternative sheaths like PE, PVC, or CPE available upon request |
