WDZA-YJY Low Smoke Halogen-Free Cross-linked Polyethylene (LSZH XLPE) Power Cable
High-Quality Flame-Retardant Cable Meeting the Highest Fire Safety Requirements
Highest Flame Retardant Rating for Critical Power Systems
WDZA-YJY cable is a low-smoke halogen-free (LSZH) cross-linked polyethylene (XLPE) insulated copper core power cable designed for low-voltage distribution environments that meet the most stringent fire safety standards.
This cable meets WDZA (Class A flame retardant) performance standards, can withstand harsh fire conditions, effectively inhibits flame spread, and minimizes secondary fire hazards, making it a reliable choice for large public infrastructure and safety-critical facilities.
WDZA-YJY is not a general-purpose cable, but a top-of-the-line fire-resistant component in modern electrical systems.
Why WDZA-YJY is Ideal for High-Risk Projects
-
WDZA Class A Flame Retardant Performance
Even in cable bundle installations, it maximizes the prevention of flame spread.
-
Extremely low smoke emissions
Maintains clearer evacuation routes and improves emergency response efficiency.
-
Zero halogen, non-corrosive
Does not release toxic or corrosive gases, effectively protecting personnel, steel structures, and electronic equipment.
-
XLPE high-temperature performance
Excellent dielectric strength, capable of withstanding higher operating temperatures.
-
Compliant with regulatory requirements
Meets common fire performance requirements in transportation, energy, and public infrastructure projects.
WDZA-YJY Typical Applications
WDZA-YJY optical cables are widely used in:
- Metro and high-speed rail systems
- Underground tunnels and stations
- Airports and aviation facilities
- Hospitals and emergency centers
- Large public spaces and stadiums
- Data centers and mission-critical buildings
- Especially suitable for enclosed spaces and densely populated areas.

Frequently Asked Questions (FAQ)
What does WDZA-YJY mean?
WDZA indicates Class A flame retardancy, while YJY refers to copper core power cables with cross-linked polyethylene (XLPE) insulation and a low-smoke halogen-free (LSZH) sheath.
When should WDZA-YJY be used instead of WDZB or WDZBN?
WDZA-YJY should be selected when regulations or project specifications require the highest flame retardancy.
Can WDZA-YJY replace traditional YJV cables?
Yes. WDZA-YJY offers higher fire safety and environmental performance.
Is WDZA-YJY suitable for underground installation?
Yes, especially suitable for tunnels, stations, and enclosed underground spaces.
Do you provide fire performance test documentation?
Yes. Factory test reports and third-party inspection reports are available upon request.
