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

Key Features

  • Fire resistance: Maintains circuit operation under direct flame

  • Halogen-free: Reduces toxic and corrosive gas emissions

  • Low smoke emission: Improves visibility and safety during fire evacuation

  • Excellent mechanical and thermal properties

  • Resistant to moisture, chemicals, and UV (with appropriate sheath)
