Product Description
NH-YJV Fire-Resistant XLPE Power Cable 0.6/1kV for Emergency Circuits
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.

-
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.

Question 1: What is the application of NH-YJV?
NH-YJV is used in critical low-voltage circuits that must maintain power supply in the event of a fire, such as emergency lighting, alarms, smoke extraction, and fire pumps, while also taking advantage of the performance of cross-linked polyethylene (XLPE) insulation.
Q2 Is NH-YJV the same as flame-retardant cable?
A No. Flame-retardant cables limit the spread of flames, while fire-resistant cables are designed to maintain circuit integrity in the event of a fire. NH indicates the fire resistance requirement.
Q3 What is the typical rated voltage?
A NH-YJV is typically used as a 0.6/1kV low-voltage power cable for fixed installations.
Q4 What are the commonly used cable specifications for emergency systems?
A Emergency lighting and control power supplies commonly use 1.5 to 10 mm² cables, while feeders for safety equipment typically use 16 to 120 mm² cables, depending on the load and distance.
Q5 What information is needed for a quick quote?
A. Fire resistance duration/rating, standards, conductor configuration, specification sheet, total meters, installation route, destination, and packaging requirements.
Q6. Can NH-YJV be used for underground wiring?
A. Primarily used for wiring in protected buildings. If the wiring is underground and there are mechanical risks, armored fire-resistant wiring should be considered depending on project requirements.
