Prevent Fire Spread LSZH Cables 1.5mm2-300mm2 Low Smoke Zero Halogen Cable

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 vs. Standard Flame-Retardant Cables

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.
