0.6/1kV To 33kV XLPE PVC Armored Cable YJLHV22 Waterproof IEEE

YJLHV22 is a low-voltage aluminum core power cable optimized for underground and protected fixed installation environments, particularly suitable for applications requiring both cost control and mechanical protection. It typically features a stranded aluminum core conductor insulated with cross-linked polyethylene (XLPE) and equipped with a steel tape armor (STA) layer for enhanced compressive strength, and a PVC outer sheath for durability. YJLHV22 is widely used in long-distance feeders, campus and industrial park power distribution, building access lines, and trench or conduit cabling, applications where unarmored cables are more susceptible to damage under traction, backfilling, and long-term line loads.

If your project requires armored low-voltage cable and your Bill of Quantities (BOQ) allows for aluminum core conductors, YJLHV22 is a wise purchasing choice, helping to reduce overall material costs while maintaining the robust structure required for underground cabling.

Typical rated voltage: 0.6/1 kV

Application: Low-voltage feeders and branches in fixed installations

Please confirm the required standards, conductor grades, and acceptance tests specified in the Bill of Quantities (BOQ).

Availability depends on required standards, core identification method, armor construction, and sheath formulation.

• Underground cable trenches and conduit systems
• Protective trench wiring in industrial facilities and parks
• Incoming lines to main low-voltage switchboards in buildings
• Utility corridors and cable channels with compression risks
• Large distribution systems where aluminum wire is more cost-effective for long-distance cabling
• Fixed installations requiring armor protection to ensure line reliability

• Conductor: Stranded aluminum wire
• Insulation: Cross-linked polyethylene (XLPE)
• Side Pad: Protective pad layer beneath the armor layer
• Armor: Steel tape (STA), often associated with V22 construction in many naming systems
• Outer Sheath: Polyvinyl chloride (PVC)
• Application Type: Fixed installation, especially suitable for underground protective distribution lines

• Conductor Stranding and Resistance Control
• By controlling the aluminum stranding, conductivity, flexibility, and stable termination performance are balanced.
• Cross-linked Polyethylene (XLPE) Insulation Extrusion and Cross-linking
• The insulation layer is extruded and cross-linked to form a robust dielectric layer suitable for low-voltage distribution.
• Core Wire Assembly and Geometry Control
• The core wires are identified and geometry controlled to improve roundness and facilitate smoother drawing and sheathing.
• Side Pad Formation
• A side pad is applied to protect the core wire assembly and provide a stable base for the placement of the armor layer.
• Steel Strip Armor
• The steel strip is wound in a spiral pattern with controlled overlap, primarily providing mechanical reinforcement to resist compression and external pressure.
• PVC Sheath Extrusion and Finishing
• A PVC sheath is extruded to protect the armor layer and inner layer, and then marked for traceability and project control.
• Routine Quality Inspections
• Typical inspections include conductor resistance, insulation thickness verification, spark testing, voltage testing, dimensional inspection, and sheath integrity checks.

• When a project requires armored low-voltage cables for underground use, please select YJLHV22. To optimize costs, protective wiring paths and aluminum conductors can be used.
• Carefully select the aluminum conductor size based on load current, wiring path length, grouping, ambient temperature, and allowable voltage drop.
• Confirm the termination requirements for the aluminum conductors in your project to ensure long-term connection stability.
• Specify the reel length to reduce the number of joints and speed up installation.

What are the main applications of YJLHV22?

It is used for cost-effective low-voltage power distribution and features armored protection. It is commonly used in underground cable trenches, protective trenches, and utility corridors, and is suitable for building and industrial feeders.

Why choose aluminum conductors?

Aluminum reduces material costs for long-distance and large-size cables. Proper sizing and termination are crucial for reliable performance.

What does V22 typically represent?

In many naming systems, it indicates a PVC-sheathed steel tape armored construction. Always follow the definitions in the reference standards.

Can YJLHV22 be directly buried?

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

What are the most commonly used specifications?

4-core and 5-core cables of 25 to 95 mm² are commonly used in distribution networks. Single-core cables of 150 to 240 mm² are commonly used for high-current feeders, depending on the load and distance.
