NH-YJV 0.6/1kV Low Voltage Fire-resistant XLPE Power Cable for High-density Indoor & Emergency Load Projects

NH-YJV 0.6/1kV is a national standard fire-resistant low-voltage fixed-laying cable. Its structure consists of a high-purity copper conductor, an inorganic fire-resistant sheath, cross-linked polyethylene (XLPE) insulation, and a polyvinyl chloride (PVC) outer sheath, with no steel tape armor.

NH Definition: The inorganic fire-resistant structure ensures continuous power supply under standard flame burning tests; YJV Definition: Cross-linked polyethylene insulation + PVC outer sheath.

Market Positioning: A preferred cable for critical load circuits in fire emergency situations, widely used in mid-to-high-end buildings, new energy, and municipal transportation projects; highly popular in domestic government tenders and bulk procurement in overseas markets such as Southeast Asia and the Middle East.

• Graded Fire Resistance
  Two selectable fire resistance grades meet different fire protection codes; fire pumps, emergency lighting, and other equipment can operate stably and continuously within the specified combustion time, meeting fire safety acceptance standards.
• Superior High-Temperature Heat Dissipation
  XLPE insulation material has a dielectric loss far lower than traditional PVC insulation materials such as NH-VV, making it suitable for densely stacked wiring in cable shafts, avoiding aging caused by heat accumulation.
• Lightweight Structural Advantages
  The unarmored streamlined cable body reduces the overall weight of the cable and the bending radius, significantly improving the efficiency of cable pulling in concealed conduits and high-rise vertical shafts.
• Comprehensive Moisture Protection
  The integrated extruded outer sheath + tightly wrapped inner fire-resistant layer effectively prevents moisture penetration, suitable for damp basements, semi-buried cable trenches, and underground pipe racks.
• Extra-Long Service Life
  Antioxidants and UV-resistant additives are added to the insulation layer and sheath, with a designed service life exceeding 35 years under standard installation conditions, reducing the investment for later circuit maintenance for project owners.
• Stable and compact structure
  Low water absorption and environmentally friendly filler ensure the cable's rounded appearance and avoid damage caused by local insulation extrusion during on-site cable pulling.

• NH-A: Super high-rise buildings, enclosed underground integrated pipe corridors, critical circuits for core medical emergency response
• NH-B: Ordinary multi-story commercial buildings, conventional indoor factory fire protection circuits

Our technical team can provide free consultation services on matching local fire protection standards based on the project construction area.

Minimum bending radius ≥ 12 times the outer diameter of the finished cable; prevent sharp metal from scratching the outer sheath during pipe threading.

Multi-layer bundled cables should have reasonable heat dissipation gaps; the factory provides current carrying capacity classification data for different laying methods for engineers to perform load calculations and cable selection.

• Strictly differentiate circuit characteristics: Only fire-fighting mandatory load circuits should use NH-YJV; general lighting and power circuits should use conventional YJV to avoid over-specification procurement and wasted funds.
• Phased Construction Cooperation: Support phased delivery according to project construction progress to reduce the buyer's on-site warehousing costs and capital occupation.
• Special Customization Requirements: For coastal salt spray areas and corrosive gas environments in workshops, enhanced anti-corrosion outer sheaths can be customized before ordering.

• CCC Mandatory Certification
• Full-Type Inspection Reports from National Authoritative Testing Institutions
• Third-Party Fire Resistance Testing Certificates (Covering All Standards)
