0.6/1kV YJV22 Low Voltage Cable 33kV Copper XLPE Armored Cable

YJV22 is a 0.6/1kV copper core, XLPE insulated, steel tape armored, PVC sheathed power cable suitable for fixed installations. It is ideal for underground conduits, protective trenches, and utility corridors, providing enhanced mechanical protection and stable low-voltage performance.

When your lines require more protection than the basic sheath, choose YJV22. This armored low-voltage power cable is designed to withstand installation stresses, effectively preventing compression and maintaining stable feeder performance in underground and conduit environments where reliability is critical.

YJV22 is a widely used armored low-voltage power cable for fixed installations. It typically uses stranded copper core conductors for efficient power transmission, an XLPE insulation layer for strong dielectric properties, an inner liner to support the armor interface, steel tape armor for mechanical protection, and a PVC outer sheath to enhance its abrasion and environmental resistance in common installation environments. YJV22 cables are commonly used in underground cable trenches, protective trenches, and equipment access areas, where unarmored cables may be subject to higher compressive forces, construction loads, or impact risks.

• Underground feeders in commercial buildings, residential buildings, and industrial plants
• Pipeline distribution lines in campuses and industrial parks
• Protective trench wiring for site and perimeter distribution
• Basement service corridors and utility tunnels with high mechanical risks
• Indoor/outdoor feeder transitions via conduits, sleeves, and conduits
• Plant distribution; line protection reduces downtime risk

• Underground conduits and conduits
• Properly backfilled protective trenches
• Utility corridors and fixed protective outdoor lines

Not suitable for dragging, coiling, or repeated moving

• Steel tape armor improves compressive strength and resistance to external mechanical stress, helping to reduce the risk of damage to underground lines and lines under construction.
• Copper conductors ensure stable power supply to feeders.

• XLPE insulation ensures stable dielectric and thermal properties, meeting the requirements of continuous feeder operation.

• The YJV22's universal sizing, repeatable construction, and export drum packaging make it suitable for phased delivery and multi-site projects.

• Size Selection

  Select the cross-sectional area based on current, distance, permissible voltage drop, grouping, environmental or soil conditions, and installation method. Voltage drop control is typically a priority for long feeders.

• Termination and Connections

  Use certified terminals and the correct crimping tools, applying controlled torque. Plan the drum length to minimize field joints, especially in underground wiring.

• Line Design

  If direct burial is required, confirm relevant standards and specify appropriate construction and burial protection methods.

• Copper Stranded Wire and Resistance Control

  Conductor stranding is controlled to ensure stable resistance and facilitate installation.

• XLPE Insulation Molding

  Extrusion and cross-linking processes are used to form a uniform dielectric layer suitable for low-voltage applications.

• Core Assembly and Geometry Control

  Core wires are stranded to maintain roundness and improve conduit insertion performance.

• Protective Layer and Armor Structure

  The protective layer protects the insulated core wires; the steel tape armor layer is wound in a controlled overlap manner to provide mechanical protection.

• Sheath and Marking

  A polyvinyl chloride (PVC) sheath is used to enhance abrasion resistance and protection, and features clear markings for easy traceability.

• Routine Inspections

  Typical inspection items include conductor resistance, insulation thickness, spark/voltage testing according to standards, dimensional inspection, and sheath/armor integrity checks.
