WDZ YJY23 Electric Power Cable Steel Tape Armored LSZH XLPE Insulation
Industrial Power Cables WDZ YJY23 Steel Tape Armored LSZH XLPE Insulation
WDZ-YJY23 Low Smoke Halogen-Free Steel Tape Armored Power Cable
The Perfect Combination of Safety and Mechanical Strength for Underground Power Systems
Designed for Power Distribution, Ensuring Zero Failures
WDZ-YJY23 cable is a low smoke halogen-free (LSZH) cross-linked polyethylene (XLPE) insulated steel tape armored copper core power cable designed for low-voltage power transmission environments with high mechanical requirements and stringent safety regulations.
Utilizing fire-resistant LSZH material and steel tape armor, this cable provides a dual protection solution against fire risks and physical damage—crucial for underground networks, industrial areas, and infrastructure corridors.
WDZ-YJY23 is not designed for ordinary installations but is built for long-term reliable operation under harsh conditions.
