NH-VV Industrial Power Cable Copper Core Fire Resistant Cable

NH-VV Fire-Resistant XLPE Power Cable Copper Core PVC Sheath Critical Circuits

NH-VV follows the requirements of GB/T 19666-2019 for fire-resistant cables.

• Special fire-resistant layer applied around the conductor
• Designed to withstand approx. 800–900 °C fire conditions
• Maintains circuit integrity and power delivery for at least 90 minutes under test

This gives fire protection systems precious time to operate, including:

• Fire-fighting pumps and hydrant systems
• Emergency and escape lighting
• Smoke exhaust and pressurization fans
• Alarm, detection and monitoring circuits

The PVC sheath and insulation used in NH-VV have inherent flame-retardant characteristics:

• No flaming droplets
• No rapid flame travel along the cable route
• Helps limit flame spread in cable ladders and shafts
• Lower smoke generation than ordinary non-flame-retardant PVC

This contributes to slower fire growth along wiring routes and improves conditions for occupants and rescue teams.

In normal operation, NH-VV behaves like a stable, general-purpose building power cable:

• Stranded copper conductors for good conductivity and low voltage drop
• PVC insulation with solid dielectric strength for low-voltage distribution

• 0.6/1 kV rated voltage, suitable for:

  • Power risers and distribution feeders
  • Lighting circuits
  • Emergency and essential loads

For designers and facility owners, this means one cable type that supports both everyday operation and fire-survival performance on key circuits.

NH-VV’s construction is compact and relatively flexible, making it easier to route through complex spaces:

• Suitable for cable trays, conduits, direct burial and trench installations
• Can be installed in vertical shafts, risers, basements and equipment rooms

• Bending radius guidelines:

  • Single-core: ≥ 20 × cable diameter
  • Multi-core: ≥ 15 × cable diameter

This gives installers and contractors the freedom to design routes that comply with both space constraints and fire code requirements.
