WDZ-YJY23 LSZH XLPE Copper Cable With STA Armor For LV Underground Runs

WDZ-YJY23 is a low-voltage copper core power cable with cross-linked polyethylene (XLPE) insulation, steel tape armor (STA) protective layer, and a low-smoke halogen-free (LSZH) outer sheath. It is designed for fixed installations, suitable for underground or mechanically sensitive lines, and requires fire resistance to reduce smoke concentration and the release of corrosive gases. WDZ-YJY23 is widely used in incoming lines, underground cable trenches, cable trays, and protected distribution lines in public utilities and industrial sites.

In international procurement, WDZ-YJY23 is positioned as a high-end low-voltage solution, combining safety and line durability, especially suitable for projects where compression risks or line stress cannot meet the requirements of standard LSZH cables.

Typical low-voltage rated voltage: 0.6/1kV

Please confirm the rated voltage and required LSZH and flame retardant test ratings according to applicable project standards.

Final supply depends on conductor grade, armor construction, and Low Smoke Halogen-Free (LSZH) composite system. Please confirm the specific construction to ensure compliance with tender requirements.

Low Smoke Halogen-Free Sheathing systems are typically used to reduce smoke and corrosive gases during fires, thereby improving visibility and reducing secondary damage to equipment.

Steel-tape armor is designed to enhance resistance to external pressure and mechanical stress, thereby increasing the reliability of pipes, trenches, and protected underground passages.

XLPE insulation provides reliable electrical and thermal performance in building and industrial power distribution systems, even under continuous loads.

XLPE insulation is commonly used in transportation facilities, public buildings, and large commercial sites that typically require low-smoke halogen-free (LSZH) performance, and where wiring includes underground sections.

Standardized configurations, universal sizes, and roll packaging options facilitate matching of bills of quantities (BOQs) and phased delivery.

• Underground cable trenches and trench distribution
• Building incoming lines and main low-voltage distribution lines
• Cable corridors, galleries, and protective tunnels
• Industrial facilities subjected to path pressure and mechanical stress
• Public buildings requiring low-smoke halogen-free (LSZH) and armor protection
• Fixed installations at risk of external compression

1. Copper Conductor Preparation and Stranding
   Copper is drawn and stranded to the specified conductor grade. Conductor quality control ensures stable resistance and a consistent insulation coating.
2. Cross-linked Polyethylene (XLPE) Insulation Extrusion and Cross-linking
   XLPE insulation is extruded and cross-linked to form a robust dielectric layer suitable for low-voltage distribution.
3. Core Identification and Wiring
   Insulated cores are identified and stranded to the specified number of cores. Filler and binding tape are used as needed to maintain the stability of the cable geometry.
4. Inner Liner Formation
   An inner liner is coated to protect the stranded cores and provide a smooth base for the steel tape armor.
5. Steel Strip Armor Applications
   The steel strip is wound in a spiral pattern with controlled overlap, primarily providing mechanical protection against compression and external pressure.
6. Low Smoke Halogen-Free Sheath Extrusion Molding
   Using low smoke halogen-free sheath compounds, extruded to provide line protection and specific fire-retardant properties.
7. Routine Testing and Inspection
   Typical inspections include conductor resistance, insulation thickness checks, spark testing, voltage testing, dimensional verification, and sheath integrity checks. Relevant documentation can be provided upon request.

It is used for low-voltage distribution lines requiring Low Smoke Halogen-Free (LSZH) performance and steel tape armor, commonly found in underground cable trenches, groves, passages, and building inlets.

Steel tape armor improves the resistance of protected underground lines to external pressure and compression, helping to reduce the risk of installation and backfill damage.

LSZH reduces the release of smoke and corrosive gases during a fire, thus improving evacuation visibility and reducing secondary damage to equipment, especially in enclosed spaces.

It is typically used for conduits and trenches. The suitability for direct burial depends on soil conditions, mechanical risks, and local requirements. Please provide your line details for proper matching.

Select the size based on current requirements, distance, permissible voltage drop, grouping conditions, and ambient temperature. Please provide your load and line length for practical size selection.
