3.6/6kV 6/10kV XLPE Flame Retardant Cable NH-YJV For Emergency Feeders

NH-YJV is a fire-resistant low-voltage cross-linked polyethylene (XLPE) power cable designed to maintain circuit integrity and operate continuously for a period of time during fire exposure, in accordance with applicable standards. It is typically used in emergency and life-safety power circuits to ensure power continuity for evacuation and firefighting operations. NH-YJV features copper conductors, XLPE insulation, and integrated fire-resistant elements in its construction, making it suitable for critical feeders powering emergency lighting, fire pumps, smoke exhaust fans, booster systems, and important switchboards.

For cross-border sourcing, NH-YJV is an ideal choice for projects requiring fire-resistant XLPE insulated power cables, offering compliance, superior performance, and ease of installation in building and infrastructure wiring.

Typical rated voltage: 0.6/1 kV

Please confirm the required rated voltage, fire resistance rating, and duration in your Bill of Quantities (BOQ) and project standards.

Availability depends on conductor grade and fire-resistant construction requirements of relevant standards.

• Fire-resistant continuity, ensuring life safety
  Designed to keep emergency power circuits operational for a period of time during a fire, supporting evacuation systems and fire-fighting equipment.
• XLPE insulation, superior thermal performance
  XLPE insulation core material has stable dielectric and thermal properties, making NH-YJV suitable for emergency feeders with continuous load requirements.
• Compliance Requirements for Public and Enclosed Facilities
  Commonly used in hospitals, shopping malls, high-rise buildings, stations, and infrastructure projects where emergency feeders must remain operational in the event of a fire.
• Efficient EPC Procurement and Repeatable Bills of Quantities
  Universal feeder sizes and repeatable construction support standardized procurement and phased delivery.
• Easy Installation and Termination
  The YJV type construction supports easy termination and routing planning in typical building power distribution environments.

1. Copper Conductor Preparation
   Copper is drawn and stranded to meet resistance requirements and installation flexibility objectives.
2. Fire-Resistant Component Integration
   Special fire-resistant layers are applied according to required standards to ensure circuit integrity in a fire.
3. XLPE Insulation Extrusion and Crosslinking
   XLPE insulation is extruded and crosslinked to form a robust dielectric layer suitable for low-voltage feeders.
4. Cable and Core Assembly
   For multi-core designs, insulated cores are stranded with a controlled pitch; fillers and adhesives can be used to stabilize the geometry.
5. Sheath Extrusion and Finishing
   An outer sheath is applied to provide mechanical protection and improve installation durability, followed by marking and packaging controls for project delivery.
6. Routine Testing and Compliance Checks
   Typical checks include conductor resistance, insulation thickness control, spark testing, voltage testing, dimensional verification, and continuity checks. Fire resistance verification is performed according to the required rating.

• When a project requires fire-resistant low-voltage cross-linked polyethylene (XLPE) power cables to ensure the emergency feeder operates normally during a fire, select NH-YJV.
• Confirm the fire resistance duration and reference standards to avoid incorrect replacement.
• Select the number of cores based on system design and neutral/PE resistance requirements.
• Select the cross-sectional area based on load current, line length, ambient temperature, grouping, and allowable voltage drop.
• If the line is underground or has high mechanical requirements, specify whether armored fire-resistant cables are required.
