Underground Feeders YJLHV22 STA Cable PVC Aluminum XLPE Cable

YJLHV22 is a low-voltage aluminum core power cable designed for cost-effective power distribution with enhanced mechanical protection. It typically consists of an aluminum core conductor, cross-linked polyethylene (XLPE) insulation, and a steel tape armor (STA) layer, all sheathed with polyvinyl chloride (PVC). This construction is widely used in underground and protected fixed installations where external pressure, trench backfill stress, and line durability are critical considerations. YJLHV22 is commonly used in building feeders, industrial park power distribution, campus utilities, and long-distance low-voltage lines, where the aluminum core conductor, when properly sized, reduces material costs while maintaining reliable performance.

Typical Rated Voltage: 0.6/1 kV

Aluminum conductors meet low-voltage power distribution requirements while reducing costs for long-distance and large-section lines (provided the size is chosen appropriately).

Steel tape armor enhances resistance to external pressure and compression, improving the reliability of underground cable trenches and ducts.

XLPE insulation provides reliable dielectric strength and thermal properties for continuous load feeders.

The PVC outer sheath is widely applicable, suitable for fixed installations, and features good abrasion resistance and ease of handling.

Common size ranges, standardized constructions, and export-grade drum supply support phased delivery and inventory planning.

• Conductor: Aluminum
• Insulation: Cross-linked polyethylene (XLPE)
• Padded layer: Protective padding layer beneath the armor layer
• Armor layer: Steel tape (STA), often associated with "V22" construction in many naming systems
• Outer sheath: PVC
• Application: Low-voltage fixed installation, especially suitable for underground power distribution

The aluminum conductor stranding is strictly controlled to meet the required flexibility and resistance targets, thereby ensuring stable termination and wiring installation.

The insulation layer is extruded and crosslinked to form a robust dielectric layer suitable for low-voltage feeder applications.

Cores are identified and laid up in a controlled geometry to maintain roundness and dimensional stability.

Side pads are laid to protect the core assembly and provide a smooth base for the armor.

Steel tape is wound in a spiral pattern with controlled overlap to improve compressive strength and resistance to external pressure.

An extruded PVC outer sheath protects the armor and insulation system and is marked for easy traceability and project control.

Typical inspections include conductor resistance, insulation thickness verification, spark testing, voltage testing, dimensional inspection, and sheath integrity checks.

1. Please confirm the standards and conductor requirements referenced in your Bill of Materials (BOQ).
2. Select the correct aluminum conductor size to handle current and voltage drops, especially for long-distance layups.
3. Select the core configuration based on the neutral and protective layer (PE) design.
4. Confirm the type of layup and whether additional mechanical protection is required.
5. Specify the preferred reel length to reduce joints and speed up installation.
6. If there are areas with water immersion, chemicals, or special soil conditions, please specify the environmental conditions.

• What are the main uses of YJLHV22?

  It is used for cost-effective low-voltage power distribution with armored protection, typically in underground cable trenches, trenches, and protective wiring, suitable for building and industrial feeders.

• Why choose aluminum conductors instead of copper conductors?

  Aluminum conductors reduce material costs for long-distance and large-cross-section lines. Proper sizing and termination are crucial for ensuring reliable performance.

• What does V22 usually stand for?

  In many naming systems, it refers to a steel tape armored, PVC sheathed construction. Please always follow the definitions in the reference standard.

• Is YJLHV22 suitable for direct burial?

  It is typically installed in conduits and protective trenches. The suitability for direct burial depends on soil conditions, mechanical risks, and local regulations. Please provide route details for proper selection.

• What are the commonly used procurement specifications?

  25 to 95 mm² 4-core and 5-core cables are commonly used for building and campus power distribution. 120 to 240 mm² single-core cables are commonly used for high-current feeders, depending on the load and distance.
