WDZ-YJFE is a high-performance, halogen-free, low-smoke, fire-resistant power cable designed for safe and reliable electricity transmission in densely populated or safety-critical environments.
The name breaks down as follows per Chinese cable nomenclature:
W = Halogen-free
D = Low smoke emission
Z = Flame retardant
YJ = Cross-linked polyethylene (XLPE) insulation
F = Flexible stranded conductor
E = Polyolefin sheath (typically LSZH – Low Smoke Zero Halogen)
This cable meets the highest safety standards for fire performance, making it ideal for modern buildings where human safety and system integrity during emergencies are paramount.
WDZ-YJFE Specification
| Conductor | Flexible stranded copper (Class 5), IEC 60228 compliant |

WDZ-YJFE Advantages
1. Life-Safety First
Emits minimal toxic smoke and no corrosive halogen gases during combustion-critical for evacuation and firefighting in subways, hospitals, and high-rises.
Meets EN 50575 (EU CPR) and GB 31247-2014 (China fire safety grading: B1-level).
2. Superior Electrical Performance
XLPE insulation offers higher current-carrying capacity, better aging resistance, and lower dielectric loss vs. PVC.
3. Environmentally Responsible
Fully compliant with RoHS and REACH; safe for indoor use and recyclable.
4. Flexible & Easy to Install
Stranded conductors and soft LSZH sheath allow easy pulling in conduits and tight spaces.
WDZ-YJFE Applications
Public Infrastructure: Subways, airports, railway stations
High-Rise Buildings: Elevator power, emergency lighting circuits
Healthcare & Education: Hospitals, schools, laboratories
Commercial Complexes: Shopping malls, data centers, office towers
Industrial Facilities: Clean rooms, control rooms, fire pump systems
> 💡 Note: For applications requiring circuit integrity during fire (e.g., fire alarms, smoke exhaust), specify the WDZN-YJFE variant with a fire-resistant layer.
