Product Description
WDZ-YJY23 LSZH XLPE Steel Tape Armored Cable 0.6/1kV for Underground
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.

Reasons the Buyer Choose WDZ-YJY23
Low Smoke Halogen-Free (LSZH) Safety Protection for Enclosed and Public Environments
Low Smoke Halogen-Free Sheath Systems are designed to reduce smoke concentration and corrosive gases during fires, thereby improving evacuation visibility and reducing equipment corrosion damage.
Steel tape armor for underground line protection
Steel tape armor enhances resistance to external pressure and compression, thereby increasing the reliability of conduits, trenches, and protected underground passages.
XLPE insulation for stable low-voltage distribution
XLPE insulation provides reliable electrical and thermal performance under continuous load, suitable for building and industrial feeders.
A balanced solution for compliance and durability
WDZ-YJY23 is ideal when standard low-smoke halogen-free (LSZH) cables are insufficient and armored protection is required without opting for a heavier protection design.
Procurement value for EPC and infrastructure projects
Universal configuration, predictable reel scheduling, and scalable supply make it suitable for phased deliveries and large bills of quantities (BOQs).

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.

FAQ
What is WDZ-YJY23 used for
It is used for LV distribution routes that require LSZH fire-safety performance and steel tape armor protection, commonly in underground ducts, trenches, and protected corridors.
What does the “23" structure provide
It commonly refers to a steel tape armored construction in many markets, improving resistance to external pressure and compression in underground routes, subject to the referenced standard.
Why choose LSZH for underground building feeders
LSZH systems reduce smoke and corrosive gas generation in fire scenarios, support safer evacuation in buildings and reduce corrosion damage to equipment, especially in enclosed routes.
Can WDZ-YJY23 be used in direct burial
It is widely used in ducts and trenches. Direct burial suitability depends on soil condition, mechanical risk, and local requirements. Provide
