Introduction (Marketing-Driven + Focused on SEO and Geo-Optimization) Underground cable failures cost billions of dollars annually to infrastructure projects worldwide in terms of downtime and repair costs. WDZ-YJY23 halogen-free low-smoke interlocked armored cable eliminates these risks with its industrial-grade durability and environmental safety. Featuring high-purity stranded copper conductors, cross-linked polyethylene (XLPE) insulation, interlocked hot-dip galvanized steel tape armor, and a halogen-free polyolefin sheath, this cable can withstand 15kN impact (heavy machinery impact), effectively preventing soil corrosion and water infiltration, and releases no toxic gases when burned. This cable operates stably in extreme temperatures ranging from -45°C in the Arctic to 65°C in the desert and humid tropical soils. It is certified by the EU (CE/RoHS 3.0), North America (UL/cUL), Australia (SAA), and the Middle East and North Africa (SASO), making it an ideal underground power solution for smart cities, mining operations, and coastal development projects worldwide.
WDZ-YJY23 is a highly reliable, low-voltage (0.6/1kV) halogen-free, low-smoke, flame-retardant, interlocked armored power cable designed for long-term underground power transmission in high-risk environments where mechanical protection, environmental safety, and weather resistance are crucial. Its unique layered structure ensures comprehensive performance: Category 2 stranded copper conductors (low resistance, stable power supply), XLPE insulation (high temperature resistance, low transmission loss), halogen-free moisture-proof filler (prevents internal water ingress), interlocked hot-dip galvanized steel tape armor (core anti-damage and anti-rust layer), and halogen-free polyolefin outer sheath (flame retardant, UV resistant, chemical corrosion resistant). "WDZ" = Halogen-free (W) + Low Smoke (DZ) + Flame Retardant; "YJY" = XLPE insulated halogen-free polyolefin sheath; "23" = Interlocked double-layer steel tape armor (2) + polyolefin outer sheath (3). Its highlights include: the interlocked steel tape design (compared to flat steel tape) increases mechanical strength by 50%, while the hot-dip galvanizing treatment ensures over 60 years of rust resistance in underground environments—far exceeding standard armored cables. It is not just a cable, but a long-term investment in the stability of underground power systems.
100% interlocking coverage, withstands 15kN impact and 12kN compression (compliant with IEC 60502-1 Type 2 armor standard). Direct burial without protective conduit (depth ≥ 0.6 meters), resists construction damage, rodent bites, and rock abrasion—reducing underground installation costs by 45% compared to unarmored cables.
Halogen-free insulation, filler layer, and sheath constitute a triple environmental safety layer, compliant with RoHS 3.0 and REACH standards (free of substances of very high concern). Smoke density (SDR ≤ 10) ensures unimpeded evacuation during underground fires; no corrosive smoke protects precision equipment and personnel. Certified by the EU Ecolabel, US EPA, and Australian GECA—ideal for enclosed underground tunnels and utility manholes.
Halogen-free polyolefin sheath with added antifreeze, UV resistance, and salt spray resistance, ensuring stable operation in temperatures ranging from -45°C to 95°C. Resistant to permafrost cracking (Nordic Europe), desert sand erosion (Middle East and North Africa), tropical humid environments (Southeast Asia), and coastal seawater corrosion (Australia) – with zero performance degradation under extreme weather conditions.
Low capacitance and low impedance design, fully compatible with Industrial Internet of Things (IIoT) and smart grid monitoring systems (AMI, SCADA). XLPE insulation minimizes transmission losses (≤2.1% for 16mm² cross-section), supporting long-distance underground power distribution (up to 800 meters for 16mm² cross-section) – crucial for smart city utility networks.
Certified by CE/RoHS 3.0 (EU), UL/cUL (North America 600V), SAA (Australia/New Zealand), SASO (Middle East and North Africa), and ISO 14001 (Environmental Management System). A single cable can meet the needs of high-risk markets worldwide, avoiding the costs of duplicate certifications. Ample inventory (shipping within 3 days) and global shipping partners (DHL/FedEx/sea freight) reduce delivery times by 30% compared to competitors.

WDZ-YJY23 cables are specifically designed to meet the high-risk underground power needs of global infrastructure projects, covering application scenarios in regions with high compliance requirements:
Yes. Its flame-retardant (compliant with IEC 60332-1-2 standard) and high-temperature resistant (long-term temperature resistance up to 95℃) design can withstand the radiant heat of wildfires. Halogen-free sheathing does not release toxic gases at high temperatures, and the armor layer protects against falling debris—we have supplied over 3,000 kilometers of cable for utility projects in fire-prone areas of Australia.
Interlocking steel tape armor (WDZ-YJY23) features a "locking" design that evenly distributes impact force, providing 50% higher mechanical strength than non-interlocking flat steel tape. It also prevents water from seeping into the armor gaps, making it ideal for wet or coastal underground environments—non-interlocking steel tape is only suitable for dry, loose soil.
We recommend using the dedicated WDZ-YJY23 underground connector kit (waterproof, corrosion-resistant, flame-retardant), which is matched to the cable's performance. The kit includes heat-shrink tubing, armored connectors, and moisture-proof filler to ensure reliable connections. Free connector guides and online training are available with bulk orders.
General soil: ≤3 meters; Heavy traffic areas (highways, industrial areas): ≤5 meters; Coastal reclamation areas (waterlogged soil): ≤2 meters. Interlocking armor and corrosion-resistant sheathing ensure performance even at the maximum burial depth—we will provide customized burial depth recommendations based on the soil type of your project.
No, it is designed for low-voltage (0.6/1kV) applications. For high-voltage (10kV+) underground engineering, we offer WDZ-YJLV23 (aluminum conductor) and WDZ-YJY23-HV (high-voltage version), which have enhanced insulation performance—both maintain the same armor and environmental characteristics as WDZ-YJY23.
Yes. For orders exceeding 1000 meters, we will provide free third-party testing reports (issued by SGS, BV, or TÜV) covering flame retardancy, smoke density, armor strength, and environmental compliance. These reports are globally recognized, ensuring successful project acceptance and market access.
