XLPE Copper Fire Rated Cable 500V NH-YJV 4 Cores 5 Cores Fire Proof Cable

NH-YJV Fire-Resistant XLPE Copper Power Cable for Emergency Feeders

NH-YJV is a fire-resistant low-voltage copper core power cable designed for emergency feeders and critical distribution lines that, according to relevant standards, must remain energized for a period of time under fire conditions. It features cross-linked polyethylene (XLPE) insulation to ensure stable thermal and electrical performance, and a dedicated fire-resistant layer to help maintain circuit integrity in fire environments. NH-YJV is widely used in high-density buildings, transportation facilities, industrial parks, and infrastructure projects where continuous power supply is required to ensure evacuation, fire protection, and life-saving services.

For cross-border sourcing, NH-YJV can serve as a compliant cable for emergency distribution, meeting the project's requirements for both XLPE insulation and fire resistance in standardized feeder solutions.

Typical rated voltage: 0.6/1 kV

Please confirm the exact rated voltage and required fire resistance duration/class listed in your Bill of Materials (BOQ).

• 1C for high-current feeders and phase-separated wiring

Final supply depends on conductor grade and fire-resistant construction required by specified standards.

• Emergency lighting feeders and critical switchboards
• Fire pump power feeders and critical pump room circuits
• Smoke exhaust and stairwell booster fan feeders
• Emergency ventilation and critical HVAC power lines
• Critical services for transportation facilities and public infrastructure (depending on the project)
• Critical circuits requiring design continuity in data centers and equipment rooms

• Ensuring circuit integrity for life-saving power supplies
  Fire-resistant construction helps maintain the operation of emergency feeders during a fire, thus supporting evacuation and firefighting operations.
• XLPE Insulation Supports Higher Continuous Load Capacity
  XLPE insulation is widely used in low-voltage feeders due to its stable thermal properties during continuous operation and dense cable routing.
• Clearer EPC Project Feeder Planning
  Standard core wire options and a universal size range simplify bill of materials matching, reduce substitution risks, and support repeated sourcing across multiple locations.
• Reliable Operation Over Long Distances
  Suitable for main and branch feeders where voltage drop control and stable insulation performance are critical for system reliability.
• Optimized Project Delivery
  Reel packaging, controllable reel lengths, and project marking support phased deployment, pull planning, and field installation arrangements.

1. Conductor Production
   High-purity copper is drawn and stranded to the specified conductor grade to meet resistance targets and facilitate bending during wiring installation.
2. Fire-Resistant Layer Integration
   A dedicated fire-resistant layer is applied according to relevant standards. This layer is a critical structural element for maintaining circuit integrity in the event of a fire.
3. XLPE Insulation Extrusion and Crosslinking
   XLPE is extruded and crosslinked around the conductor to form a stable dielectric layer suitable for low-voltage feeder applications.
4. Core Identification and Routing
   After identification, the insulated cores are stranded according to the required core structure, with strand length and filler controlled to maintain roundness and dimensional stability.
5. Sheath and Surface Finishing
   The outer sheath protects the cable structure and enhances the durability of fixed installations. Final marking ensures traceability and facilitates project management.
6. Routine Testing and Compliance Release
   Typical checks include conductor resistance, insulation thickness control, spark testing, voltage testing, dimensional verification, continuity testing, and fire resistance verification according to specified ratings.

• Conductor: Copper
• Fire Resistance: Fire-resistant layer (depending on standard)
• Insulation: Cross-linked polyethylene (XLPE)
• Outer Sheath: Specified according to project requirements (typically polyvinyl chloride (PVC), or low smoke halogen-free (LSZH) according to project requirements)
• Application: Fire-resistant low-voltage power supply feeder for emergency circuits

• If your project requires fire-resistant low-voltage feeders to ensure emergency load power supply during a fire, please select NH-YJV.
• Please confirm the fire resistance duration/rating and acceptance testing methods required in the Bill of Quantities (BOQ).
• Select the number of conductors based on the distribution scheme and neutral/protective electrical (PE) requirements.
• Select the size based on current, distance, ambient temperature, cable grouping, and permissible voltage drop.
• If the wiring includes underground or high-risk mechanical sections, please specify whether an armored fire-resistant version is required.
