Zero Halogen Flame Retardant Cable 11KV Fire Resistant Low Smoke Cables

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.
