XLPE STA Flame Resistant Cable 1.5mm2 To 400mm2 ZR-YJV22 Waterproof

When your project requires both the robustness of underground installations and flame retardancy, the ZR-YJV22 is an ideal upgrade. It combines copper core conductivity, XLPE insulation, steel tape armor for conductor protection, and a flame-retardant PVC sheath system to help limit the spread of flames along cable routes within buildings and industrial installations.

The ZR-YJV22 is a low-voltage copper core power cable designed for stationary installations requiring mechanical protection and a flame-retardant rating. Its construction typically includes stranded copper conductors, XLPE insulation to ensure stable low-voltage performance, an inner protective layer with steel tape armor (STA) for enhanced compressive strength and resistance to external stresses, and a flame-retardant PVC outer sheath. "ZR" is generally used to indicate flame retardancy in its naming system, while "22" is broadly associated with steel tape armor construction. This model is widely used in underground conduits, protected trenches, cable corridors, building shafts, and incoming lines, where bills of quantities include safety clauses and line durability requirements.

Typical Rated Voltage: 0.6/1 kV

Applications: Low-voltage distribution feeders and branches (fixed installation)

• Low-voltage trunk lines entering buildings and passing through shafts and corridors
• Underground conduits and cable trenches in commercial and industrial sites
• Protective trench wiring within factories, parks, and infrastructure projects
• Cable corridors and utility passages requiring armored protection
• Dense cable lines requiring flame retardancy to reduce the risk of flame spread

• If Low Smoke Halogen-Free (LSZH) performance is required: Select LSZH flame retardant type
• If fire resistance (circuit integrity) is required: Select fire-resistant/NH type
• If frequent relocation is required: Select flexible cable

• Single-core high-current feeder (phase-separated) wiring
• 2C Single-phase feeder and dedicated circuit
• 3C Three-phase without neutral (depending on design)
• 4C Three-phase plus neutral distribution
• 5C Three-phase plus neutral plus protective power (depending on design)
• 3+1 and 3+2 feeder configurations used in many Bills of Quantities (BOQs)

• Flame Retardant Upgrade, Ensuring Cable Wiring Safety
  Using ZR-grade flame-retardant materials effectively limits the spread of flames along the cable, ensuring cable wiring safety in shafts, corridors, and dense wiring environments.
• Armored Protection, Enhanced Underground Durability
  Steel tape armor enhances compressive strength and resistance to external pressure, reducing the risk of damage in conduits and protective trenches.
• XLPE Insulation, Ensuring Stable Low-Voltage Performance
  XLPE insulation ensures reliable electrical performance under continuous low-voltage power distribution loads.
• Copper Conductor, Strong Conductivity
  Copper conductors ensure efficient power supply over long distances and achieve stable voltage drop control.
• Suitable for EPC projects and large bills of quantities procurement
  Common sizes and familiar structures facilitate bill of quantities matching, phased delivery, and repeat supply.

• Conductor: Copper stranded wire
• Insulation: Cross-linked polyethylene (XLPE)
• Side layer: Protective side layer beneath the armor layer
• Armor layer: Steel tape (STA)
• Outer sheath: Flame-retardant polyvinyl chloride (PVC)
• Installation types: Fixed installation, underground, and protective wiring

1. Copper conductor stranding
   Controlled stranding structure helps improve resistance stability and facilitates installation.
2. Cross-linked polyethylene (XLPE) insulation extrusion and cross-linking
   Insulation layer molding ensures durable dielectric properties in low-voltage distribution systems.
3. Core identification and assembly
   Core wires are identified and stranded according to a controlled geometry to ensure consistent roundness and smoother pull-out.
4. Side layer preparation
   Side layers are laid to protect the core wires and provide a stable base for the armor layer.
5. Steel Strip Armor
   The steel strip is wound in a controlled overlapping manner to enhance its resistance to compression and external pressure.
6. Flame-Retardant PVC Sheath and Marking
   A flame-retardant PVC sheath is extruded to protect the armor layer and meet the specified flame-retardant rating, followed by marking.
7. Routine Inspections
   Typical inspections include conductor resistance, insulation thickness, spark testing, voltage testing, dimensional inspection, and sheath integrity.

• When Bill of Quantities (BOQ) For applications requiring flame retardancy and armored protection for underground or protective wiring, select ZR-YJV22.
• Select the number of cores based on the neutral and PE design.
• Select the cross-sectional area based on current, distance, grouping, ambient temperature, and permissible voltage drop.
• If low smoke halogen-free (LSZH) or fire-resistant properties are required, specify these requirements to match the correct model.
