XLPE STA Aluminium Cables YJLV22 0.6/1kV LV Underground Cable

YJLV22 XLPE Aluminum STA Armored Power Cable

YJLV22 is a low-voltage aluminum core power cable with cross-linked polyethylene (XLPE) insulation and steel tape armor (STA), designed for fixed installation environments requiring additional mechanical protection. It is widely used in underground conduits, trenches, utility corridors, and building main power distribution lines, meeting customer needs for long-distance, cost-effective feeder cables and enhanced compressive strength and resistance to external stresses after backfilling.

YJLV22 is frequently chosen for infrastructure and industrial projects due to its high cost-effectiveness despite its large cross-sectional area and its reel packaging, which facilitates practical installation planning. YJLV22 is ideal for low-voltage power distribution when the line is located underground or within conduits and the design requires mechanical protection.

Key Selling Points for Cross-Border Buyers

• Cost-Effective Aluminum Conductors for Long-Distance Transmission Lines
  Aluminum conductors help control material costs for long-distance low-voltage feeders and bulk purchases, especially for large cross-sections.
• Steel Tape Armor for Line Protection
  Steel tape armor enhances resistance to external pressure and mechanical stress, thereby increasing the reliability of conduits, trenches, and protected underground passages.
• XLPE Insulation for Reliable Low-Voltage Distribution
  XLPE insulation supports continuous load performance and improves the thermal performance of modern distribution networks.
• Project-Ready Logistics and Reel Planning
  Universal feeder sizes and reel supply facilitate transportation, unloading, and installation for EPC and infrastructure projects, ensuring on-time completion.
• Suitable for Infrastructure, Industrial, and Utility Lines
  YJLV22 is suitable for many standard underground distribution scenarios requiring armored low-voltage feeders.

Typical Applications and Use Cases

• Underground power distribution in conduits and trenches
• Industrial plant feeders and substation-to-load lines
• Commercial building incoming and main distribution lines
• Utility tunnels, cable corridors, and protective walkways
• Fixed lines requiring additional mechanical protection against compression

Manufacturing Process and Process Description

• Aluminum Conductor Stranding and Compaction
  Aluminum wire is drawn and stranded to the required conductor grade, and is typically compacted to stabilize the geometry and improve the consistency of the insulation coating.
• XLPE Insulation Extrusion and Crosslinking
  The insulation layer is extruded and crosslinked to form a stable insulated core suitable for low-voltage power distribution.
• Core Laying and Assembly (Multi-Core Design)
  Insulated cores are laid according to the specified number of cores, with filler and binding tape added as needed to maintain shape stability.
• Bedding Layer Formation
  Before armoring, a bedding layer (usually PVC or a specified compound) is laid to provide a flat base and protect the insulated cores.
• Steel Strip Armor
  The steel strip is wound in a spiral pattern with controlled overlap, primarily providing mechanical protection against external pressure and compression.
• Outer Sheath Extrusion and Marking
  The outer sheath (typically PVC or a specified compound) is used for environmental protection and surface marking, and can optionally be used for project identification.
• Routine Testing and Inspection
  Typical inspection items include conductor resistance, insulation thickness, spark testing, voltage testing, and dimensional verification. Relevant documentation can be prepared according to procurement requirements.

Selection Guide

• For underground or protective laying methods with high compression risk and requiring armored low-voltage feeders, please select YJLV22.
• Select the appropriate number of cores based on network design and neutral/protection layer requirements.
• Confirm the use of correct aluminum termination fittings and installation methods to ensure long-term stable and reliable connections.
• If your project requires low smoke halogen-free (LSZH), flame retardant properties, or enhanced corrosion resistance, please specify these requirements to ensure matching of the sheath and internal structure.
