ZR-YJV22 XLPE Armored Cable 12/20kV Fire Resistant Cable For Underground

ZR-YJV22 is a low-voltage copper core power cable that combines flame-retardant properties with steel tape armor, providing enhanced mechanical protection in fixed installations. This cable is commonly used in lines requiring increased fire safety and protection against compression and external stresses, such as underground conduits, trenches, cable corridors, building inlets, and industrial distribution lines. The cable typically features copper conductors insulated with cross-linked polyethylene (XLPE) and an outer sheath system that meets the relevant standard flame-retardant rating requirements.

For cross-border sourcing, ZR-YJV22 is positioned as a practical "fire safety + line protection" low-voltage feeder cable suitable for contractors and EPC purchasers working on infrastructure, public building, and industrial site projects.

Typical rated voltage: 0.6/1 kV

Please confirm the flame-retardant rating required in your project standards and Bill of Quantities (BOQ).

Availability depends on conductor grade, armor construction, and required standards.

• Flame retardant rating ensures safer cable laying

  Designed to help limit the spread of flame along the cable laying path, thereby improving the safety of risers, corridors, and dense cable laying.

• Steel tape armor provides mechanical protection

  The armor construction improves resistance to compression and external pressure, enhancing the reliability of underground conduits, trenches, and protected corridors.

• XLPE Insulation Ensures Stable Low-Voltage Feeder Performance

  XLPE insulation provides reliable dielectric strength and thermal properties under continuous load.

• A Balanced Solution for Infrastructure and Industrial Projects

  A viable upgrade option when standard unarmored flame-retardant cables fail to meet line conditions.

• Easy for EPC Contractors

  Common sizes, standardized construction, and reel designs facilitate bill of materials matching, phased delivery, and predictable field installation planning.

• Underground power distribution in conduits and trenches
• Building incoming lines and main low-voltage distribution lines
• Cable corridors, utility passageways, and protected tunnels
• Industrial sites with external pressure risks along cable lines
• Fixed installations requiring flame retardant ratings and armor protection

1. Copper Conductor Production

   Copper is drawn and stranded to the specified conductor grade to meet resistance targets and provide suitable installation flexibility.

2. XLPE Insulation Extrusion and Crosslinking

   XLPE is extruded and crosslinked to form a stable low-voltage dielectric layer.

3. Core Identification and Wiring

   Insulated cores are identified and laminated in a controlled geometry; fillers and adhesives are used to maintain roundness and dimensional stability.

4. Side Layer Formation

   Side layers are laid to protect the cores and provide a smooth base for the armor layers.

5. Steel Tape Armoring

   Steel tape is wound in a controlled overlap pattern, primarily providing mechanical protection against compression and external pressure.

6. Flame-Retardant Outer Sheath Extrusion

   A sheath compound system that meets the required standard flame retardancy rating is selected, processed, and then extruded at a controlled thickness.

7. Routine Testing and Compliance Checks

   Typical checks include conductor resistance, insulation thickness control, spark testing, voltage testing, dimensional verification, and sheath integrity checks. Flame retardancy verification is performed according to the required rating.

Conductor:

Copper

Insulation:

Cross-linked Polyethylene (XLPE)

Armor:

Steel tape armor (22 structure, specific standard subject to change)

Outer Sheath:

Flame-retardant composite material (specific standard subject to change)

Installation Method:

Fixed, including underground conduits and protected wiring

1. When the project requires flame-retardant low-voltage feeder cable with steel tape armor protection for underground or mechanically sensitive lines, please select ZR-YJV22.
2. Confirm the flame retardancy rating required by the reference standard.
3. Select the number of cores based on the distribution scheme and neutral/protection layer requirements.
4. Select the cross-sectional area based on current, line length, grouping, ambient temperature, and allowable voltage drop.
5. If the line also requires low-smoke halogen-free, specify low-smoke halogen-free armored cable instead of the standard ZR sheath system.

What is ZR-YJV22 used for?

It is used for low-voltage power distribution lines that require a flame retardant rating and steel tape armor for line protection, commonly found in conduits, trenches, corridors, and building inlets.

What does 22 construction usually represent?

In many market practices, it indicates a steel tape armored construction designed to improve resistance to compression and external pressure; specific requirements are subject to reference standards.

What is the difference between ZR-YJV22 and ZR-YJV?

ZR-YJV22 features added steel tape armor for mechanical protection, while ZR-YJV is typically unarmored. Both meet the flame retardancy requirements of relevant standards.

Can ZR-YJV22 be used for direct burial?

It is typically used in conduits and trenches. The suitability for direct burial depends on soil conditions, mechanical risks, and local requirements. Please provide detailed installation route information for proper selection.

What sizes are commonly used by contractors?

10 to 50 mm² 4-core and 5-core cables are commonly used for building distribution, while 95 to 240 mm² 1-core cables are commonly used for high-current feeders.
