Product Description
Robust XLPE Cable for Transportation & Industrial Automation
WDZ-YJY23 armored cable delivers superior performance for electrical wiring in safety-critical transportation infrastructure and industrial automation systems.
Four Major Advantages for Safety-Critical Projects
1. LSZH Flame-Retardant System – Fire Safety Without Toxic Gases
WDZ-YJY23 is engineered to reduce harm in case of fire:
- Flame-retardant performance: Self-extinguishes after ignition source removal and prevents flame propagation
- Halogen-free formulation: No chlorine, bromine, or similar halogen gases released during burning
- Low smoke output: Maintains higher visibility in escape routes for safer evacuation
- Low corrosive impact: Combustion by-products with mild acidity (pH ≥ 4.3) protect equipment
2. Double Steel Tape Protection – Built for Direct Burial & Concealed Installations
For routes demanding mechanical and environmental resilience:
- Enhanced mechanical protection: High resistance to pressure and tearing (up to 1100 N/100 mm)
- Direct burial ready: Can be buried at 0.7 m depths without additional protective ducts
- Rodent and insect defense: Armored structure prevents animal damage during concealed routing
- Ingress protection: IP65 rating provides resistance to dust, water, and mechanical impact
- Service life: 25+ years of service under normal conditions
3. High-Grade Insulation & Sheath – Stable Electrical Performance
- XLPE Insulation: Continuous working temperature up to 90°C, withstands -40°C without embrittlement
- PE Sheath: Non-toxic, excellent weathering and UV resistance, maintains flexibility
- Copper Conductor: High-purity electrolytic copper (99.97% IACS) for low resistance and heat build-up
4. Standards-Driven & Widely Applicable
Complies with mandatory fire and environmental standards including GB/T 19666, GB 12666, and GB 50217.
Typical applications: Metro systems, airports, hospitals, data centers, and industrial sites with halogen-free requirements.

Frequently Asked Questions
Q1: Why choose low smoke zero halogen instead of standard PVC-sheathed cables?
A: LSZH materials greatly reduce smoke output and eliminate halogen acid gases, making escape routes more visible and limiting toxic exposure during fires.
Q2: Is WDZ-YJY23 suitable for direct burial?
A: Yes. The double steel tape armoring and polyethylene outer sheath make it suitable for direct-burial applications when installed according to engineering codes.
Q3: How does this cable protect sensitive equipment?
A: Halogen-free materials and low corrosive gas production significantly lower the risk of damage to metallic parts and electronics during fires.
Q4: Can WDZ-YJY23 be used outdoors?
A: Yes. The PE sheath offers excellent weather and UV resistance for both indoor and outdoor installations.
Q5: What flame-retardant classes are available?
A: Standard designs target Class B, while higher levels such as Class A can be provided on request.
Q6: How do I know if WDZ-YJY23 is the right choice?
A: If your project involves crowded spaces, enclosed environments, or strict fire audits—such as high-rise buildings, public transportation, or data centers—WDZ-YJY23 is typically a strong candidate
