WDZ-YJY23 XLPE LSZH Cable 3 Core Armoured Cable 16mm Underground Use

WDZ-YJY23 is a low-voltage copper core power cable designed for fixed installation environments that meet underground laying and fire safety regulations. It features cross-linked polyethylene (XLPE) insulation for reliable low-voltage distribution; steel tape armor (STA) enhances its resistance to external pressure and laying stress; and the outer sheath is made of low-smoke halogen-free (LSZH) material, effectively reducing smoke and corrosive halogen gases generated in a fire. This cable is commonly used in underground conduits, cable trenches, service corridors, and building access lines, where standard unarmored LSZH cables may face a higher risk of damage during traction, backfilling, and long-term laying.

• Underground cable trench feeders in commercial and industrial areas
• Protective power distribution lines laid in trenches within factories and industrial parks
• Incoming lines to main distribution panels in buildings
• Service tunnels, cable corridors, and utility corridors
• In public utilities, enclosed or interconnected lines must meet Low Smoke Halogen-Free (LSZH) requirements
• Projects requiring armor protection to reduce installation and compression damage

• Conduit and cable trench systems, protected trenches, cable corridors, protected tunnel lines
• Fixed installation only

• Copper stranded wire (conductor class meets required standards)

• 1C for high-current feeders and phase-separated wiring
• 2C for auxiliary low-voltage power supplies and dedicated single-phase loads
• 3C for three-phase circuits without a neutral conductor (depending on design)
• 4C for three-phase distribution with a neutral conductor
• 5C for three-phase distribution with a neutral conductor and protective insulation (PE) Power distribution (depending on design)

Common feeder layouts in Building Quantity Lists (BOQ) are 3+1 and 3+2 structures.

• 4 core x 25
• 4 core x 35
• 4 core x 50
• 5 core x 16
• 5 core x 25
• 5 core x 35
• 3 core x 16
• 3 core x 25
• 1 core x 150
• 1 core x 185
• 1 core x 240

3+1 and 3+2 structures are based on local design and BOQ. Specific requirements will apply.

Note: Final supply depends on the required standards, conductor class, low smoke halogen-free (LSZH) composite system, and armor construction.

• Conductor Control

  The copper stranded wire is controlled to meet resistance targets and withstand actual bending during installation.

• Cross-linked polyethylene (XLPE) Insulation and Cross-linking

  The insulation layer is formed using extrusion and cross-linking processes to create a robust dielectric layer suitable for low-voltage applications.

• Layup and Stabilization

  The cores are assembled with controlled geometry before armoring to improve roundness and dimensional consistency.

• Armor Applications

  The steel strip is wound using a controlled overlap method, primarily providing mechanical protection against external pressure and compression.

• Low Smoke Halogen-Free Sheath

  The low smoke halogen-free sheath is produced using an extrusion molding process to protect the inner conductor layer and meet specified low smoke halogen-free performance requirements.

• Routine Quality Inspections

  Typical release checks include conductor resistance, insulation thickness control, voltage testing, spark testing, dimensional inspection, and sheath integrity verification. Other conformity verifications will be performed according to specified standards and classifications.

1. Confirm the required standards and relevant terms in the Low Smoke Halogen-Free (LSZH) performance Bill of Materials (BOQ)
2. Select core configuration based on neutral/protective electrical (PE) design and feeder scheme
3. Determine dimensions based on load current, path length, grouping, ambient temperature, and voltage drop limitations
4. Define path type: cable trench, conduit, tunnel, corridor, or inlet
5. Specify preferred reel length to reduce joints and speed up installation
6. If there are special risks associated with the path (impact, rodents, immersion, chemical exposure), specify them in the Request for Quotation (RFQ) for proper matching
