1.5mm2 To 1000mm2 Steel Tape Armored Cable WDZ-YJY23 LSZH XLPE

WDZ-YJY23 is a low-smoke halogen-free (LSZH) sheathed, cross-linked polyethylene (XLPE) insulated, and steel-tape armored low-voltage power cable designed for fixed installations with complex routing and clearly defined safety requirements. It is suitable for underground and protected distribution lines requiring additional resistance to external stresses, while reducing smoke emissions and the generation of corrosive halogen gases in the event of a fire. For contractors and engineering, procurement, and construction (EPC) contractors, WDZ-YJY23 is a practical choice, meeting the needs for line durability and enhanced fire resistance in enclosed or building connections.

Typical Low Voltage Rating: 0.6/1kV

Applications: Building feeders, industrial park power distribution, industrial low-voltage trunk and branch lines (fixed installation)

• Incoming lines from transformer areas to main low-voltage switchboards, with routes including buried or protected channels.
• Underground conduits and piping systems in industrial parks, commercial complexes, and residential developments.
• Protected trench routes, considering backfill pressure and long-term external loads.
• Cable ducts, service corridors, and utility corridors, with safety management requirements conforming to Low Smoke Halogen-Free (LSZH) standards.
• Low-voltage distribution lines in public utilities, where path protection and safety clauses are clearly specified in procurement documents.

• Mobile equipment, dragging, frequent bending, or flexible dragging services.
• High-impact areas where additional mechanical protection requirements are not confirmed.

• 1C for high-current feeders and phase-separated cabling
• 2C for dedicated single-phase feeders and auxiliary power supplies
• 3C For three-phase circuits without a neutral conductor (depending on specific design)
• 4C for three-phase distribution with a neutral conductor
• 5C for three-phase distribution with a neutral conductor and protective grounding (depending on specific design)
• 3+1 and 3+2 for feeder arrangements used in many Bills of Quantities (BOQs)

Adapted to local design specifications 3+1 and 3+2 Constructions

Note: Final construction details depend on the required standards, conductor class, and Low Smoke Halogen-Free (LSZH) composite system.

1. Confirm the wording of the Low Smoke Halogen-Free (LSZH) requirements in the Bill of Quantities. (BOQ)
2. Select conductor configuration based on neutral and protective grounding design.
3. Select cross-sectional area based on load current, line length, environmental conditions, grouping method, and allowable voltage drop.
4. Clearly define the installation path (conduit, protective trench, utility access, inlet).
5. Specify reel length preference to reduce joints and speed up installation.
6. If the environment involves water, chemicals, or special mechanical risks, declare this in the Request for Quotation (RFQ) to select appropriate sheathing and protection solutions.

• How does WDZ-YJY23 differ from standard Low Smoke Halogen-Free (LSZH) power cable?

  It features added steel tape armor, providing better resistance to external pressure and installation stress, making it more suitable for protected underground lines and incoming lines.

• What does "23" in the name mean?

  In many naming systems, "23" is associated with a steel tape armor construction. The specific definition must follow the standards specified in the project documentation.

• Is WDZ-YJY23 suitable for flexible or mobile equipment?

  No. It is designed for fixed installations. For equipment that is frequently moved, choose a flexible cable designed for dynamic applications.

• Can it be used for direct burial?

  It is typically used for protected underground lines. The suitability for direct burial depends on local regulations, soil conditions, and mechanical risks. Please provide line details for proper selection.

• What is the most commonly used specification in projects?

  Multi-core 4-core and 5-core cables ranging from 16 to 50 mm² are widely used in power distribution; high-current feeders typically use single-core cables ranging from 120 to 240 mm², depending on the load and distance.

• What information is needed for an accurate quote?

  Standard requirements, conductor configuration, size list, total length, route type, destination, reel preference, and required documentation.
