WDZ-YJY23 LSZH XLPE STA Armored Power Cable 0.6/1kV For Underground Feeds

WDZ-YJY23 is a low-voltage copper core power cable designed for fixed installations, meeting two key requirements:

• Low Smoke Halogen-Free (LSZH) safety, reducing smoke and corrosive halogen gas emissions in fire scenarios;
• Steel Tape Armor (STA) protection, enhancing the cable's ability to withstand external stresses in underground or mechanically sensitive lines;

WDZ-YJY23 is widely used in underground conduits, cable trenches, trenches, service tunnels, and building access lines, especially suitable for situations where installation stress, backfill pressure, or line compression risk is higher than standard indoor cable trays. If your tender requires low smoke halogen-free (LSZH) performance and the line includes underground sections, WDZ-YJY23 is a practical and compliant choice.

Typical Rated Voltage: 0.6/1 kV

System Type: Low-voltage distribution feeder and sub-feeder circuits

Note: Low Smoke Halogen-Free (LSZH) and flame retardant testing requirements shall comply with the standards specified in your Bill of Materials (BOQ).

• Building incoming lines from transformer rooms to main low-voltage switchboards
• Campus power distribution in underground conduits and protection corridors
• Low-voltage power distribution in industrial plants in trenches and utility corridors
• Public utilities with designated enclosed lines using Low Smoke Halogen-Free (LSZH)
• Stationary power distribution lines in cable corridors and service tunnels
• Lines with armor selected to reduce the risk of damage under traction, backfilling, and long-term external stress

• Flexible drag applications and environments with frequent movement
• Unprotected lines directly buried in harsh soils without confirmation of local regulations and additional protection requirements

• 1C: High-current feeder, phase-separated wiring
• 2C: Single-phase feeder and auxiliary circuit
• 3C: Three-phase circuit without neutral wire
• 4C: Three-phase circuit with neutral wire
• 5C: Three-phase circuit with neutral wire + PE
• 3+1, 3+2: Commonly used feeder structures in many building projects

• 4C x 16, 4C x 25, 4C x 35, 4C x 50
• 5C x 10, 5C x 16, 5C x 25, 5C x 35
• 3C x 10, 3C x 16, 3C x 25
• 1C x 120, 1C x 150, 1C x 185, 1C x 240
• 3+1 and 3+2 Combination specifications depend on local feeder design.

• Conductor: Copper (stranded; conductor grade conforms to standards)
• Insulation: Cross-linked polyethylene (XLPE)
• Inner Layer: Filler/adhesive added as needed to ensure roundness and stability
• Padded Layer: Protective padding layer for supporting the armor
• Armor: Steel tape armor (STA), often associated with a "23" construction in many markets
• Outer Sheath: Low smoke halogen-free (LSZH) compound system
• Installation Type: Fixed installation, especially suitable for underground protection lines

1. Step 1: Conductor Stranding

   The copper wire drawing and stranding process is strictly controlled to ensure resistance stability and a workable bending radius during drawing.

2. Step 2: Cross-linked polyethylene (XLPE) Insulation and Cross-linking

   The insulation layer is extruded and cross-linked to form a robust dielectric layer designed specifically for low-voltage distribution applications.

3. Step 3: Core Identification and Routing

   Identify the cores as required (by color or number) and route them in a controlled geometry to ensure cable stability and ease of installation.

4. Step 4: Pad Formation

   Apply padding to protect the cable cores and provide a smooth surface for armor layer installation.

5. Step 5: Steel Tape Armoring

   Wrap steel tape in a controlled overlap pattern, primarily providing mechanical protection against external pressure and compression.

6. Step 6: Low-Smoke Halogen-Free Sheath Extrusion

   Extrude a low-smoke halogen-free sheath to protect the armor layer and provide target smoke/corrosive gas performance as specified.

7. Step 7: Routine Testing

   Typical checks include conductor resistance, insulation thickness control, spark testing, voltage testing, dimensional inspection, sheath integrity, and necessary verifications according to specified standards.

1. Confirm the required standards and Low Smoke Halogen-Free (LSZH) in the Bill of Materials (BOQ) Performance Requirements
2. Select core configuration based on power grid design (neutral/protection layer strategy)
3. Determine size based on load current, length, grouping, ambient temperature, and permissible voltage drop
4. Confirm line type: cable trench, trench, tunnel, corridor, or inlet
5. Determine reel length preference to reduce joints and speed up installation
6. Specify if the line has a high impact risk or rodent risk to match the protection rating

• What are the main applications of WDZ-YJY23?

  It is used for low-voltage power distribution, especially suitable for lines requiring Low Smoke Halogen-Free (LSZH) performance and steel tape armor protection, such as underground conduits, cable trenches, trenches, and incoming lines.

• What does "23" construction typically represent?

  In many market practices, "23" usually refers to a steel tape armored construction. Specific definitions and testing scope must follow the standards referenced in the tender documents.

• Why do underground lines require Low Smoke Halogen-Free (LSZH) protection?

  Many projects specify the use of Low Smoke Halogen-Free (LSZH) protection to reduce smoke and corrosive gases in enclosed or building-connected lines (e.g., tunnels, corridors, and shafts), thereby improving evacuation conditions and reducing the risk of secondary equipment damage.

• Can WDZ-YJY23 be used for direct burial?

  It is typically used for protected underground lines, such as cable trenches and trenches. The suitability for direct burial depends on local regulations, soil conditions, and mechanical risks. Please provide detailed wiring routes for proper selection.

• How to choose between single-core and multi-core cables?

  Single-core cables are typically used for high-current and phase-separated wiring. Multi-core cables simplify wiring and cable management in standard power distribution layouts. Load, wiring route limitations, and installation habits should be considered when selecting a multi-core cable.

• What information helps expedite quotation and delivery date confirmation?

  Voltage, number of cores, cross-sectional area, total length in meters, required standards, installation route, destination, reel length requirements, and documentation requirements.
