33kV Low Smoke Zero Halogen Wire WDZ-YJY23 Steel Tape Armored Cable

WDZ-YJY23 Low-Voltage Power Cable

WDZ-YJY23 is a low-voltage power cable designed for projects requiring Low Smoke Halogen-Free (LSZH) fire resistance and armored mechanical protection for underground or high-risk lines. It features copper conductors and cross-linked polyethylene (XLPE) insulation, armored with steel tape, and an outer sheath utilizing an LSZH system to reduce smoke concentration and corrosive gas release in the event of a fire. This cable is commonly used in underground conduits, trenches, cable corridors, and building inlets, particularly suitable for lines facing compression risks, backfill pressure, or high installation stress.

For cross-border sourcing, WDZ-YJY23 is positioned as a high-end "safety + protection" low-voltage cable suitable for infrastructure, public buildings, and industrial projects with specific requirements for LSZH compliance and armor durability.

Rated Voltage

Typical Rated Voltage: 0.6/1kV

Please confirm the rated voltage and required LSZH/flame retardant testing rating based on your project standards and Bill of Quantities (BOQ).

Specification Table

Selection Guide

• Choose WDZ-YJY23 when your project needs LSZH LV power cable for underground or protected routes with added mechanical protection from steel tape armor.
• Select core count based on system design and neutral/PE requirements.
• Select cross-section based on current, route length, grouping, ambient temperature, and allowable voltage drop.
• If the route has higher impact risk, rodent risk, or severe mechanical stress, specify route conditions to match the appropriate protection level.
