WDZ-YJY23 Fireproof Wire Low Smoke Halogen Free 6/10kV Flame Resistant Cable
WDZ-YJY23 Low Smoke Halogen-Free Flame Retardant Steel Tape Armored Cable
WDZ-YJY23 cable is a low smoke halogen-free (LSZH) cable with cross-linked polyethylene (XLPE) insulation and steel tape armor, designed for low-voltage power distribution applications requiring fire and mechanical protection.
This cable combines low smoke halogen-free (LSZH) fire-retardant materials with YJY23 steel tape armor, significantly improving resistance to external impact, compression, and installation stress, while substantially reducing smoke and toxic gas emissions under fire conditions.
WDZ-YJY23 cable is widely used in industrial facilities, underground installations, and infrastructure projects, meeting the high requirements for safety and physical durability.
