Underground power cables face catastrophic risks such as mechanical damage, moisture corrosion, and toxic fumes generated during fires. WDZ-YJY23 halogen-free low-smoke steel tape armored cable is the ideal solution for industrial engineers, power companies, and project managers worldwide. This cable features premium cross-linked polyethylene (XLPE) insulation, high-strength steel tape armor (≥95% coverage), and a halogen-free polyolefin outer sheath, offering excellent shock/compression resistance (up to 10kN/m), releasing no toxic gases during combustion, and allowing for direct burial without additional protection. Its operating temperature range is from -35℃ (Northern Europe) to 60℃ (Middle East), and it has passed EU (CE/RoHS 3.0), North American (UL/cUL), Australian (SAA), and Middle East & North Africa (SASO) certifications, making it a core component of globally reliable underground power distribution systems.
WDZ-YJY23 is a high-performance, low-voltage (0.6/1kV) halogen-free, low-smoke, flame-retardant steel-tape armored power cable, designed for direct burial and harsh industrial underground power distribution environments (public power grids, industrial parks, mining areas). Its reinforced multi-layered structure ensures comprehensive reliability: Class 2 high-purity stranded copper conductors (low resistance, stable transmission), XLPE insulation (anti-aging, high-temperature resistant), halogen-free low-smoke filler (moisture-proof, environmentally friendly), high-strength steel tape armor (core anti-damage layer), and halogen-free polyolefin outer sheath (flame-retardant, corrosion-resistant, UV-resistant). “WDZ" = Halogen-free (W) + Low-smoke (DZ) + Flame Retardant; “YJY" = XLPE insulation and halogen-free polyolefin sheath; “23" = Double-layer steel tape armor (2) + polyolefin outer sheath (3). Its uniqueness lies in the integrated steel tape armor layer eliminating the risk of underground mechanical damage, while the halogen-free and low-smoke characteristics address fire safety and environmental protection issues—distinguishing it from unarmored cables and traditional PVC armored cables.
Double-layer steel tape armor with ≥95% coverage, impact resistance (≤10kN) and compressive strength (≤10kN/m), conforming to IEC 60502-1 armored cable standard. Direct burial (depth ≥0.7m) without additional protective conduit, avoiding damage from construction machinery, rocks, and rodents—ideal for underground industrial and utility projects.
Compliant with RoHS 3.0 and REACH standards, free of 10 hazardous substances. It produces no toxic halogenated gases or corrosive fumes during combustion, and its smoke density (SDR ≤ 15) ensures safe evacuation in underground fire accidents. Easily passes stringent environmental tests in the EU, North America, and Australia, suitable for enclosed underground tunnels.
Utilizes a halogen-free polyolefin sheath with added antifreeze, UV resistance, salt spray resistance, and moisture-proofing agents, adaptable to a temperature range of -35℃ to 95℃. Resistant to underground moisture, soil corrosion (acidic/alkaline soils), and coastal saltwater infiltration, demonstrating reliable performance in Nordic permafrost, Middle Eastern deserts, Southeast Asian waterlogged soils, and Australian coastal soils.
High-dielectric-strength cross-linked polyethylene (XLPE) insulation minimizes power loss (≤ 2.6% for 16mm² cross-section), supporting long-distance underground power distribution (up to 700 meters for 16mm² cross-section). Compatible with smart grid monitoring systems, enabling real-time tracking of underground power status, making it an ideal choice for smart city public utility infrastructure.
CE/RoHS 3.0 (EU), UL/cUL (North America 600V), SAA (Australia/New Zealand), SASO (Middle East and North Africa), and IEC 60502 (global). A single cable can meet the needs of multiple underground engineering markets, avoiding the costs of duplicate certifications. The direct-buried design saves 35% on excavation and protective conduit costs compared to unarmored cables, thereby reducing the total project cost by 22%.

WDZ-YJY23 has an added double-layer steel strip armor, allowing for direct burial and providing impact/compression resistance; WDZ-YJY has no armor layer and is not suitable for direct burial. WDZ-YJY23 is suitable for underground and harsh industrial environments; WDZ-YJY is suitable for indoor/outdoor non-underground general power supplies—select according to the installation environment (underground or outdoor).
The double-layer steel tape armor layer forms a robust protective layer, resisting mechanical damage from construction machinery, rock impacts, and rodent bites during underground installation and operation. It also enhances the cable's structural stability, preventing deformation in deep burial (up to 5 meters) and frozen soil environments.
Yes. The halogen-free polyolefin outer sheath is fortified with corrosion inhibitors, making it resistant to corrosion in acidic, alkaline, and saline-alkali soils. For highly corrosive soils (such as chemical plant waste sites), we offer an enhanced corrosion-resistant version (WDZ-YJY23-AC), which features a special sheath coating and galvanized steel tape.
General soil: ≥0.7 meters; Farmland/light traffic areas: ≥1.0 meter; Heavy vehicle areas (highways, industrial areas): ≥1.2 meters. We recommend installing warning tape 30 cm above the cable during installation to prevent damage from accidental digging.
Yes. Our steel tape is hot-dip galvanized, and its corrosion resistance meets IEC 60502-1 standards. The outer halogen-free polyolefin sheath further isolates moisture and soil corrosives, ensuring the armor layer has a service life of over 60 years in normal underground environments.
Yes. We provide custom-made thickened steel tape armor (1.0~1.5 mm thick, standard thickness 0.8 mm) for heavy industrial scenarios (mining areas, construction sites with frequent heavy machinery operations). Custom-designed, thickened armored cables retain all certifications and offer enhanced shock resistance (up to 15 kN).
