Underground And Ducts Outdoor Low Voltage Cable 0.6/1kV 3.6/6kV

WDZ-YJY23 is a low-smoke halogen-free (LSZH) XLPE insulated copper core power cable with steel tape armor, suitable for 0.6/1kV systems. It is specifically designed for fixed installation environments such as conduits, trenches, and underground lines requiring LSZH safety and mechanical protection.

WDZ-YJY23 is ideal when your project requires LSZH low-smoke performance and additional armor protection for low-voltage cable lines underground or with high mechanical risks.

WDZ-YJY23 is a low-voltage copper core power cable typically featuring XLPE insulation, an LSZH outer sheath system, and steel tape armor. Product models are identified with "23". It is commonly used for fixed installations with high mechanical risks, such as underground conduits, trenches, utility corridors, and protected outdoor lines. Compared to unarmored low-smoke halogen-free cross-linked polyethylene (XLPE) power cables, WDZ-YJY23 cables have an additional mechanical protective layer, resisting compression and external impacts while meeting low-smoke halogen-free requirements. This helps reduce smoke and corrosive halogen gases generated in fires in confined spaces and public areas.

Copper Conductor Stranding and Resistance Control

Conductor resistance is stabilized during production to ensure performance of long-distance low-voltage feeders.

Cross-linked Polyethylene (XLPE) Insulation Extrusion and Cross-linking

The insulation layer formation ensures excellent dielectric properties and long-term stability.

Core Identification and Wiring

Cores are assembled using geometric control to improve roundness and reduce tensile friction within the conduit.

Rack Application

Racks are used to enhance armor fit and protect the insulated cores.

Steel Tape Armor

Steel tape armor uses controlled overlap and tension to provide mechanical protection against external forces. Low-Smoke Halogen-Free Sheath and Labeling

Low-Smoke Halogen-Free Sheath and Labeling

The low-smoke halogen-free outer sheath is manufactured using an extrusion molding process, balancing environmental protection and safety performance. It features clear labeling for easy traceability.

Routine Inspections

Typical inspections include conductor resistance, insulation thickness, spark testing, voltage testing, dimensional inspection, sheath integrity, and armor coverage verification.

Please confirm the following in the Bill of Materials (BOQ):

• LSZH requirements and acceptance criteria
• Armor type requirements (23 layers of steel tape) and line conditions (conduit, trench, outdoor)
• Select the core count based on the distribution design (three-phase, neutral/protection pole scheme).
• Select the cross-sectional area based on current, line length, grouping, soil/conduit thermal conditions, and permissible voltage drop.
• Determine the recommended reel length to reduce the number of joints in conduits and trenches.
