Emergency Circuits Low Voltage Cable NH-YJV Fire Resistant XLPE Power Cable

Ensure uninterrupted power supply during critical safety times. NH-YJV is a fire-resistant, low-voltage cross-linked polyethylene (XLPE) power cable designed for critical circuits, maintaining power continuity in the event of a fire and supporting life-safety systems and critical services in demanding buildings and industrial facilities.

NH-YJV is a low-voltage copper core power cable with XLPE insulation and a protective outer sheath, manufactured with a fire-resistant construction that maintains circuit integrity for a period of time under fire exposure (performance depends on required standards and test categories). Compared to PVC-insulated fire-resistant cables, NH-YJV is typically the preferred choice for low-voltage distribution projects requiring XLPE insulation performance and projects meeting emergency load fire resistance requirements. Typical applications include emergency lighting, fire pumps, smoke exhaust fans, evacuation systems, alarm systems, and critical power feeders that must remain operational during a fire.

• Typical Rated Voltage: 0.6/1 kV
• Applications: Fixed low-voltage distribution feeders and critical circuits
• Project Considerations: Ensure that the fire resistance duration and testing standards specified in the Bill of Quantities (BOQ) meet the requirements.

• Emergency lighting and evacuation guidance circuits
• Power supplies for fire alarm and detection systems
• Power supplies for fire pumps, sprinkler control systems, and critical machinery
• Power supplies for smoke exhaust and booster fans
• Public buildings, transportation hubs, hospitals, hotels, and high-occupancy locations
• Industrial sites requiring uninterrupted power supply for emergency shutdown and safety systems

• Cable trays, conduits, risers, shafts, and protected building wiring
• Fixed installation only

• 1C For single-core feeders and dedicated critical circuits
• 2C For single-phase emergency power feeders
• 3C For three-phase circuits without a neutral wire (specific design depends on actual conditions)
• 4C For three-phase plus neutral power distribution
• 5C for three-phase plus neutral plus emergency power supply (specific design depends on actual conditions)
• 3+1 and 3+2 feeder structures, specific design depends on project practice

• Fire-resistant circuit integrity, protecting critical loads

  Utilizing an NH fire-resistant structure ensures continued power supply even in the event of a fire, meeting life safety compliance requirements.

• XLPE insulation, enhancing low-voltage performance

  XLPE insulation material ensures stable dielectric properties and thermal stability for low-voltage feeders and continuous load operation.

• A Reliable Choice for Emergency Circuits and Critical Power Distribution

  Commonly used in fire pumps, smoke extraction systems, evacuation systems, and critical building equipment.

• Suitable for EPC and Public Project Procurement

  Common sizes, controlled manufacturing processes, and multiple documentation options support Bill of Quantities (BOQ) compliance and phased delivery plans.

• Conductor: Copper stranded wire
• Insulation: Cross-linked polyethylene (XLPE)
• Fire-resistant elements: Fire-resistant structure conforming to specified test categories and durations
• Outer Sheath: Protective sheath system (depending on project standards)
• Installation Types: Fixed cabling, protective paths for emergency and critical circuits

• Copper Conductor Preparation

  Copper is drawn and stranded to meet resistance targets and stable termination performance.

• Cross-linked Polyethylene (XLPE) Insulation Extrusion and Cross-linking

  The insulation layer is extruded and cross-linked to form a robust dielectric layer suitable for low-voltage operation.

• Fire-resistant Element Integration

  To ensure the integrity of the circuit under required fire-resistant testing conditions, a fire-resistant layer or fire-resistant structure is added to the cable.

• Sheathing and Marking

  The outer sheath protects the inner layers and is marked for easy traceability and project control.

• Routine Inspections

  Typical inspections include conductor resistance, insulation thickness verification, spark testing, voltage testing, dimensional inspection, and sheath integrity checks.

• If your Bill of Quantities (BOQ) For critical low-voltage circuits requiring fire resistance and circuit integrity, and for which XLPE insulation is required, please select NH-YJV.
• Please confirm the required fire resistance duration and test category in your project documents.
• Select the number of cores and cross-sectional area based on load current, distance, grouping, ambient temperature, and permissible voltage drop.
• If the project also requires Low Smoke Halogen-Free (LSZH) insulation, please specify the LSZH fire-resistant type.
