WDZ-YJY 0.6/1kV Copper XLPE Halogen-Free Low-Smoke Flame-Retardant Power Cable
When the cable runs through a building zone where evacuation has to happen during a fire — shopping malls, hospitals, transit stations, public assembly — local codes increasingly forbid halogen-content insulation that releases toxic smoke. WDZ-YJY replaces the conventional PVC sheath with halogen-free flame-retardant polyolefin (HFFR).

Overview
Conductor and XLPE insulation are identical to YJV. The differentiation is the outer sheath: HFFR (halogen-free flame-retardant) polyolefin compound that resists flame propagation per IEC 60332-3-22 Category B and emits low smoke + zero halogen acid gas under fire. Used wherever local building codes prohibit halogen-content cable on life-safety grounds.
Key Features
Halogen-free + low-smoke + flame-retardant
All three life-safety properties in one outer sheath compound — no need to specify separate FR and LSZH variants.
Building-code aligned for SEA
Specification matches the LSZH cable requirements that Indonesian, Thai, and Philippine fire codes now apply to high-occupancy buildings.
Compatible with YJV terminations
Outer dimensions match YJV at every cross-section — substitution does not require new lugs, glands, or terminations.
Applications
Public assembly buildings
Shopping malls, transit stations, airports, hospitals — anywhere evacuation must be safe during a cable fire.
High-occupancy commercial
Office building risers and tenant distribution where local code mandates LSZH on life-safety circuits.
