- Underground conduits and cable trenches
- Protective trench wiring in industrial and commercial locations
- Incoming lines to main low-voltage switchboards
- Utility corridors and cable tunnels with external pressure risks
- Indoor/outdoor feeder transitions requiring higher mechanical strength
- Fixed wiring with high cable handling and pull-out stress
Uses steel tape armor to improve compressive strength and resistance to external pressure, ensuring the reliability of protected underground wiring.
XLPE insulation provides reliable dielectric strength and thermal properties, suitable for continuous load feeders.
Copper conductors offer excellent conductivity and stable voltage drop control, making them particularly suitable for long-distance feeders.
The PVC sheath provides abrasion resistance and durable surface protection, facilitating pulling and field handling.
Standardized construction and widely used sizes facilitate repeated supply, phased delivery, and streamline bill of quantities matching.
- Conductor: Copper stranded wire
- Insulation: Cross-linked polyethylene (XLPE)
- Inner Layer: Filler/adhesive added as needed to ensure geometric stability
- Protective Layer: Protective layer beneath the armor layer
- Armor Layer: Steel tape (STA)
- Outer Sheath: Polyvinyl chloride (PVC)
- Applications: Fixed installation, especially suitable for protected underground lines
-
Conductor Preparation
Controlling the stranding pattern of the copper wires to meet resistance targets and facilitate installation bending.
-
Cross-linked polyethylene (XLPE) Insulation and Cross-linking
Using extrusion and cross-linking processes to form a stable dielectric layer suitable for low-voltage feeder applications.
-
Cable and Geometry Control
Controlling the core wire layup to maintain the cable's roundness and dimensional stability, resulting in smoother pulling and a consistent sheath finish.
-
Protective Layer Formation
Laying the protective layer to protect the cable cores and provide a stable base for the armor layer.
-
Steel Tape Armor
Using a controlled overlap method to wind steel tape, primarily enhancing the cable's resistance to compression and external pressure. PVC Sheath Extrusion and Marking
-
PVC Sheath Extrusion and Marking
PVC sheaths protect the armor layer and internal structure and are marked for easy traceability and project control.
-
Routine Inspections
Typical inspections include conductor resistance, insulation thickness verification, spark testing, voltage testing, dimensional inspection, and sheath integrity checks.

- When the line requires armor protection and fixed installation, please select YJV22 cable. For conduits, trenches, and protected underground passages.
- Select the number of conductors based on the neutral and protective earth (PE) wiring design.
- Select the cross-sectional area based on current, distance, grouping, ambient temperature, and permissible voltage drop.
- If the project requires flame retardancy, low smoke halogen-free (LSZH), or fire resistance, specify the required category to match the correct model.
- What are the main applications of YJV22?
- It is used in fixed-installation low-voltage power distribution systems, especially suitable for applications where steel tape armor is used for path protection, such as cable trenches, protective trenches, and building entrances.
- What does the number 22 usually represent?
- In many naming systems, the number 22 is often associated with steel tape armor construction. Always follow the definitions and test ranges of the relevant standards.
- What is the difference between YJV22 and YJV?
- YJV22 includes a single layer of steel tape armor, providing mechanical protection. YJV typically does not have an armor layer.
- Can YJV22 be used for direct burial?
- It is typically used in conduits and protective trenches. The suitability for direct burial depends on soil conditions, mechanical risks, and local code requirements. Please provide detailed route information for proper selection.
- What are the most commonly used specifications in projects?
- In power distribution lines, commonly used specifications are 4-core and 5-core cables with a span of 10 to 50 mm². For high-current feeders, common specifications are 95 to 240 mm² single-core cables, depending on the load and distance.
- What information is needed for a quick quote?
- Core configuration, specification list, total meters, required standards, installation route, destination, reel length requirements, and required documentation.
