3 Cores 25mm2 Aluminum XLPE Cable YJLV22 LV Power Cable STA Armor

YJLV22 is a low-voltage power cable with an aluminum conductor, cross-linked polyethylene (XLPE) insulation, and steel tape armor (STA). Designed for fixed installations, it is suitable for cable laying in conduits, trenches, and protected underground lines that may be subjected to external stresses, backfill loads, or accidental mechanical shocks. YJLV22 cables are commonly used in infrastructure and industrial power distribution due to their practical electrical performance, cost-effective conductor selection, and the additional line protection provided by the armor.

For cross-border buyers, YJLV22 cables are often the preferred choice when projects require reliable low-voltage feeder cables, are available in large quantities in reels, have predictable installation plans, and offer a competitive total cost of ownership.

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

It is essential to ensure that the rated voltage and required tests comply with local standards and project specifications.

Actual supply varies depending on standard, conductor grade, and manufacturer. Please confirm the specific structure required for your tender.

• Economical Conductor for High-Capacity Feeders

  Aluminum conductors are widely used because they effectively control material costs for long-distance and large-section lines while meeting low-voltage distribution requirements.

• Steel Tape Armor for Underground Line Safety

  Steel tape armor helps improve resistance to pressure and external stresses in ducts and trenches, thus maintaining reliability after backfilling and during on-site construction.

• XLPE Insulation for Stable and Continuous Operation

  XLPE insulation ensures reliable low-voltage distribution performance and improves thermal performance under continuous load conditions in typical feeder applications.

• Better Project Logistics and Reel Packaging

  YJLV22 is typically packaged in reels for easy phased delivery, controlled draw length, and on-site handling.

• Suitable for Infrastructure and Industrial Power Distribution

  Standardized configurations and universal sizes make it ideal for utility, plant, commercial development, and industrial park Bill of Quantities (BOQ) applications.

• Underground power distribution in cable trenches and troughs
• Main feeders from transformers to switchgear or distribution panels
• Industrial plant feeder circuits and park power distribution
• Cable tunnels, corridors, and protected underground passages
• Fixed wiring designed for mechanical protection

1. Conductor Manufacturing and Stranding

   Aluminum wire is drawn and stranded to the target conductor grade. Compaction can be performed to stabilize the conductor shape and improve the consistency of the cable structure.

2. XLPE Insulation Extrusion and Crosslinking

   XLPE is extruded and crosslinked to form a stable insulation layer suitable for low-voltage power distribution.

3. Core Laying for Multi-Core Cables

   Insulated cores are laid up to the required number of cores. Fillers and binding tape can be added to maintain stable roundness and consistent geometry.

4. Insulation Layer and Inner Layer Formation

   An insulation layer is laid to protect the insulating core and provide a smooth base for the armor layer.

5. Steel Tape Armoring Application

   Steel tape is wound in a spiral pattern and overlapped as specified to provide mechanical protection, primarily against compression and external pressure.

6. Outer Sheath Extrusion and Marking

   The outer sheath is extruded to provide environmental and mechanical protection, and surface marking and item identification are performed as needed.

7. Routine Inspection and Quality Control

   Typical inspection items include conductor resistance, insulation thickness control, spark testing, voltage testing, and dimensional verification. Item documentation can be prepared upon buyer's request.

• If your line is underground or has a protective layer and requires mechanical protection against compression, and you want to use aluminum conductors to control project costs for long-distance low-voltage feeders, choose YJLV22.
• For high-current feeders and flexible phase sequence wiring, choose 1C; for compact installations and simplified laying, choose 3C/4C/5C.
• Please confirm the termination accessories for the aluminum conductors and follow the correct connector preparation and torque specifications.
• If you require low-smoke halogen-free (LSZH), flame-retardant, waterproof, or enhanced corrosion resistance, please specify your requirements so we can match the appropriate sheath and design.

• Applications of YJLV22

  YJLV22 is used for low-voltage underground power distribution and fixed feeders, suitable for applications requiring steel tape armor in conduits and trenches for enhanced mechanical protection.

• The Role of Steel Tape Armor

  It improves the cable's resistance to external pressure and compression, helping to protect cables in underground lines after backfilling and during field operations.

• Why Use Cross-linked Polyethylene (XLPE) Instead of Ordinary Insulation Materials?

  XLPE ensures stable electrical performance and improves the thermal performance of circuits with continuous load distribution.

• Is YJLV22 suitable for direct burial?

  It is widely used in conduits and trenches. The suitability for direct burial depends on soil conditions, mechanical risks, and local requirements. Please provide wiring details for proper matching.

• What are the key points for aluminum wire termination?

  Use the correct aluminum terminals or suitable connectors where necessary, follow proper surface treatment and torque control, and adopt approved joint operation specifications to avoid overheating risks.

• Can you provide support for Bill of Materials (BOQ) matching and reel length planning?

  Yes. We can match specifications based on the BBOQ, suggest reel lengths for easy field handling, and provide packaging markings and documentation required for project control.
