1. Product Introduction
The ZR-NH-YJV Fire-Resistant Power Cable is a critical component for modern fire safety engineering. Designed to maintain power supply to essential systems during an active fire, this cable features a specialized Mica Tape barrier that protects the conductor even after the primary insulation has been consumed by flames. It is the gold standard for high-rise buildings, public transit, and emergency response infrastructure.
• Model: ZR-NH-YJV
• Voltage Rating (U₀/U): 0.6/1kV
• Flame Retardancy: Class ZA, ZB, or ZC (IEC 60332)
• Fire Resistance: Complies with IEC 60331 standards.
• Core Feature: Maintains circuit integrity for 90–120 minutes at 750–1000°C.
2. Structural Composition
Conductor: High-purity Oxygen-Free Copper (OFC), Class 2 stranded.
Fire Barrier: High-quality Mica Tape wrapped helically around the conductor. This inorganic layer provides superior heat insulation.
Insulation: XLPE (Cross-linked Polyethylene) – providing excellent electrical properties under normal operating conditions.
Filler: Flame-retardant or non-hygroscopic glass fiber/PP yarn.
Binding Tape: Fire-resistant glass fiber tape or flame-retardant non-woven fabric.
Outer Sheath: Flame-retardant PVC or LSZH (Low Smoke Zero Halogen) compound, specifically formulated to prevent fire spread.

Key Safety Advantages
Circuit Integrity: Unlike standard cables that fail instantly in a fire, ZR-NH-YJV ensures that fire pumps, emergency lights, and alarms keep running during evacuation.
Dual Protection: * Flame Retardant (ZR): Prevents the cable from acting as a "wick" that spreads fire through a building.
Fire Resistant (NH): Continues to transmit power while under direct flame contact.
Standard Compliance: Fully tested to meet international safety codes for public high-density environments.
High-Quality Mica: We use premium synthetic or phlogopite mica tape to ensure the highest heat barrier efficiency.
5. Critical Application Scenarios
This cable is mandatory for circuits that must remain operational during an emergency:
Firefighting Systems: Power supply for fire pumps, smoke extraction fans, and fire-fighting elevators.
Emergency Infrastructure: Exit signage, emergency lighting systems, and voice evacuation alarms.
High-Density Public Areas: Subways, airports, hospitals, shopping malls, and high-rise residential towers.
Data Centers: Critical power backups to ensure safe shutdown and data protection during fire incidents.
6. Testing & Quality Control
Fire Resistance Test: Samples are subjected to direct flame according to IEC 60331 to verify voltage maintenance.
Flame Propagation Test: Verified according to IEC 60332 to ensure self-extinguishing properties.
Insulation Integrity: High-voltage withstand tests are performed after the fire test to ensure post-fire stability.
