Product Description
WDZN-YJY LSZH Fire-Resistant Power Cable
Low Smoke Zero Halogen • Fire Resistant • XLPE Insulation • PE Sheath • Non-Armored
WDZN-YJY is a dual-protection safety cable built for projects where cables must not only stop burning, but also stay operational during fire conditions.
Flame retardant to limit spread • Fire resistant to maintain power • Eco-friendly & non-toxic • Lightweight & easy to install
Designed for non-direct-burial installations in ultra-high safety environments—such as high-rise towers, hospital operating areas, metro lines, airports, and emergency centers—this cable combines:
- Low Smoke Zero Halogen (LSZH) flame-retardant technology
- Certified fire resistance to maintain circuit integrity under flame
- XLPE insulation & PE sheath for long-term stability
- Non-armored, lightweight construction for easier installation
Engineered to meet stringent codes including GB/T 19666, GB 12666, GB/T 12666.6, it is tailored for projects facing the toughest fire safety acceptance checks.
Model Decoding - Double Safety in a Lightweight Design
What "WDZN-YJY" Means
| Code | Component | Function & Safety Advantage |
|---|---|---|
| WDZ | Low Smoke Zero Halogen Flame-Retardant System | Halogen-free, low-smoke formulation. Under fire, smoke density stays low (≤50%) and no corrosive halogen acid gases are released. Helps prevent flame spread and limits damage to people and equipment. |
| N | Fire-Resistant Function | Indicates fire-resistance capability in line with GB/T 12666.6 Class N. Maintains circuit integrity for approximately 90 minutes at 750°C. |
| YJ | Cross-Linked Polyethylene (XLPE) Insulation | Supports continuous operation at 90°C with high insulation resistance (≥100 MΩ·km). Low dielectric loss improves transmission efficiency. |
| Y | Polyethylene (PE) Sheath | Environmentally friendly, non-toxic outer layer with strong resistance to UV, weathering, and low temperatures. |
Compared to WDZ-YJY: WDZN-YJY adds fire-resistance capability to maintain power during fire events.
5 Key Advantages - Tailored for Critical Fire Safety Circuits
1. Flame-Retardant + Fire-Resistant - Two Layers of Protection
WDZN-YJY doesn't just slow fire; it's designed to keep critical systems energized:
- Flame-retardant behavior: Limits flame propagation and avoids burning droplets
- Fire-resistant core: Maintains circuit integrity for 90 minutes at 750°C
- Emergency support: Ensures power for fire-fighting lifts, emergency lighting, sprinkler pumps, and evacuation signage
- Low smoke, halogen-free: Minimal smoke and no toxic fumes for safer evacuation
2. Non-Armored & Lightweight - Made for Shafts, Trays & Conduits
- Typically 25-30% lighter than comparable armored cables
- Installation efficiency increases by approximately 30%
- Minimum bending radius of only ≈15* cable diameter
- Ideal for vertical shafts, cable trays, conduit wiring, and embedded runs
3. XLPE + PE Structure - Long Service Life & Stable Performance
- XLPE insulation: Operating temperature up to 90°C, handles low temperatures around -40°C
- PE sheath: Non-toxic, halogen-free with strong UV and weather resistance
- High-purity copper conductor: Conductivity close to 99.97% IACS
- Service life can exceed 25 years when installed correctly
4. High-Compliance Solution - Designed for Zero-Tolerance Fire Audits
Tailored for projects where fire inspections must be passed on the first attempt:
- Supports dual requirements of "flame-retardant + fire-resistant" cables
- Suitable for public infrastructure with strict acceptance rules
- Meets both environmental expectations and emergency power continuity needs
5. Flexible Customization - Configuration Fits the Scenario
- Flame-retardant grades: WDZ-A / WDZ-B / WDZ-C options
- Fire-resistant categories: Class N / NH as needed
- Core configurations: 1-5 cores, 1.5-400 mm² cross-sectional area
- Voltage class: Upgradable designs up to approximately 10 kV

Frequently Asked Questions
Q1: What is the main difference between WDZN-YJY and standard WDZ-YJY?
A: WDZ-YJY focuses on low smoke zero halogen flame-retardant performance. WDZN-YJY adds fire-resistance capability, meaning it can keep critical circuits energized during a fire.
Q2: When should I choose non-armored WDZN-YJY instead of an armored fire-resistant cable?
A: Choose non-armored WDZN-YJY when cables are routed through conduits, shafts, trays, ceilings or walls where they are not directly exposed to heavy mechanical loads.
Q3: How long can WDZN-YJY maintain power under fire conditions?
A: Under standard fire-resistance test conditions (750°C), WDZN-YJY maintains circuit integrity for approximately 90 minutes.
Q4: Does the LSZH formulation affect electrical performance?
A: No. The LSZH sheath and fire-resistant layer provide safety benefits while the XLPE insulation and copper conductor ensure solid electrical performance.
Q5: Can WDZN-YJY be used outdoors?
A: Yes, as long as it is not directly buried. The PE sheath offers strong UV and weather resistance.
Q6: Can you customize WDZN-YJY to match our local fire codes?
A: The cable can be configured with different flame-retardant and fire-resistance levels to align with local codes and project specifications.
