Aluminum Alloy XLPE Cable YJLHV22 Armored STA Cable For LV Underground Feeders

YJLHV22 is a low-voltage aluminum alloy conductor power cable with cross-linked polyethylene (XLPE) insulation and steel tape armor (STA). It is designed for stationary installation environments subject to compression, backfill pressure, or high mechanical risks. It is widely used in underground conduits, trenches, cable trays, and building main feeders, meeting customers' needs for lighter weight compared to copper cables and providing an additional layer of protection to ensure long-term safe operation.

YJLHV22 is commonly used in infrastructure and building power distribution projects because it balances installation efficiency, project economy, and line protection. YJLHV22 is particularly suitable for long-distance laying and large cross-sectional area lines, where laying speed, traction force, and structural load are primary procurement considerations.

Common rated voltage: 0.6/1kV (low-voltage distribution)

Rated voltage and testing requirements should be compatible with project specifications and local standards.

• 1C: High-current feeder, phase separation, long-distance transmission
• 3C: Compact three-phase feeder
• 4C: Three-phase feeder with neutral wire
• 5C: Three-phase feeder with neutral wire and protection circuit (depending on the project)

Availability depends on conductor grade, standard, and factory design. Please confirm the specific configuration to ensure compliance with bidding requirements.

• Lighter Weight, Faster Installation, Lower Support Load

  Aluminum alloy conductors reduce cable weight, thereby improving traction efficiency, reducing labor intensity, and lowering the load on trays/supports in shafts and corridors.

• Steel Tape Armor Provides Line Protection

  Steel tape armor enhances resistance to external pressure and mechanical stress, improving the reliability of conduits, trenches, and protected underground lines.

• XLPE Insulation Ensures Stable Performance

  XLPE insulation supports continuous load distribution performance and improves thermal conductivity for modern building and industrial feeders.

• Competitive Total Installation Cost for Large Sizes

  In large cross-section applications, aluminum alloy conductor solutions offer significant value for bulk purchases, especially where long-distance and large-size feeders dominate the bill of materials.

• Facilitates EPC procurement and phased delivery

  Standard configurations and common feeder sizes support reordering, phased shipments, and field-ready cable reel planning.

• Underground power distribution in conduits and trenches
• Incoming lines from transformers to main switchboards
• Main building feeders in shafts and service corridors
• Industrial park and campus power distribution networks
• Utility tunnels, cable corridors, and protected underground lines
• Fixed installations requiring additional mechanical protection

1. Preparation of Aluminum Alloy Rods and Conductor Stranding

   Alloy rods are drawn into wires, stranded to the required conductor grade, and typically compacted to ensure geometric stability and improve cable structure consistency.

2. Conductor Shielding or Insulation Layer (when required by standards)

   Insulation layers may be used to assist insulation processing and ensure surface quality, depending on design and standards.

3. XLPE Insulation Extrusion and Crosslinking

   The insulation layer is extruded onto the conductor and crosslinked (process method depends on the production line and standards) to form a stable insulating core suitable for low-voltage power distribution.

4. Core Identification and Wiring (for Multi-core Cables)

   Identify the insulated cores and strand them according to the specified number, using filler or binding tape as needed to maintain their roundness and stability.

5. Inner Sheath/Sleeve Formation

   Apply a sleeve (typically PVC or a specified compound) to provide a smooth armor base and improve mechanical integrity.

6. Steel Tape Armoring (STA)

   Roll the steel tape spirally to the required overlap and coverage. The armor design is optimized for the compressive strength of fixed underground lines.

7. Outer Sheath Extrusion

   The outer sheath (typically PVC or a project-specified composite material) provides environmental and mechanical protection, including surface markings.

8. Routine Testing and Final Inspection

   Typical factory inspections may include conductor resistance, insulation thickness, spark testing, voltage testing, and dimensional verification. Project documentation is available upon request.

For underground or protective routes with mechanical stress and compression risks, please select YJLHV22 cable. If your load is high and you wish to use aluminum alloy conductors for ease of handling over long distances, consider the following factors:

• Select the appropriate number of cores based on network design and neutral/protection requirements.
• Confirm that termination accessories are suitable for aluminum alloy conductors to ensure long-term reliability of the joints.
• If your project requires Low Smoke Halogen-Free (LSZH), flame retardant properties, or enhanced corrosion resistance, clearly specify these requirements to select the appropriate sheath and construction.

• What are the uses of YJLHV22 cable?

  It is used for fixed-installation low-voltage power distribution, especially suitable for underground conduits and trenches, building main feeders, and protected routes requiring additional mechanical protection.

• What does V22 construction mean in practical applications?

  V22 typically indicates steel tape armor to improve the cable's resistance to external pressure and mechanical stress in fixed underground routes.

• Why is aluminum alloy chosen for armored feeders?

  Aluminum alloy cables reduce cable weight, improving installation efficiency for long-distance laying, while maintaining feeder stability even with large cross-sectional areas.

• Is 0.6/1kV the only voltage rating?

  0.6/1kV is a commonly used voltage rating for low-voltage distribution. It is essential to ensure that the cable's rated voltage and testing requirements comply with local regulations and project requirements.

• What factors should the buyer consider when terminating the cable?

  Use the correct terminals, connectors, and installation methods specifically designed for aluminum alloy conductors to ensure a stable and reliable connection and reduce the risk of overheating.

• Can you provide support in terms of project documentation and reel planning?

  Yes. Our support includes packaging markings, batch records, inspection items, and reel length planning based on site handling and delivery schedules.
