Product Description
XLPE Cable Engineered to Prevent Flame Propagation and Molten Dripping with Low Smoke Zero Halogen Flame Retardant Technology
Four Major Advantages - Tailored for Safety-Critical Projects
LSZH Flame-Retardant System - Fire Safety Without Toxic Gases
WDZ-YJY23 is engineered to reduce harm in case of fire:
- Flame-retardant performance: The cable self-extinguishes after removing the ignition source and is designed to prevent flame propagation and molten dripping.
- Halogen-free formulation: No chlorine, bromine, or similar halogen gases are released during burning, so there is no thick, choking acid smoke and far lower risk of poisoning or asphyxiation.
- Low smoke output: The low-smoke sheath and flame-retardant design help maintain higher visibility; escape paths remain more visible, allowing more time for evacuation and rescue.
- Low corrosive impact: Combustion by-products exhibit relatively mild acidity (pH ≥ about 4.3), which helps protect metal supports, equipment, and cable trays, decreasing the cost of repair and replacement after a fire.
Double Steel Tape Protection - Built for Direct Burial & Concealed Installations
For routes that demand both mechanical and environmental resilience:
- Enhanced mechanical protection: Double steel tape armoring offers high resistance to pressure and tearing, typically up to around 1100 N / 100 mm.
- Direct burial ready: Can be buried at depths around 0.7 m in many designs without additional protective ducts, while coping with backfill, ground settlement, and routine construction activities.
- Rodent and insect defense: The armored structure and outer PE sheath help prevent animal damage and abrasion during concealed routing in walls, shafts, and tunnels.
- Ingress protection: Overall protection level can reach approximately IP65, providing strong resistance to dust, splashed water, and light mechanical impact.
- Service life: Combined armoring and durable sheath typically allow 25+ years of service under normal conditions, especially when installed according to code.
High-Grade Insulation & Sheath - Stable Electrical and Environmental Performance
- XLPE Insulation:
- Continuous working temperature up to 90 °C, suitable for standard 0.6/1 kV power distribution.
- Withstands low temperatures to about -40 °C without embrittlement.
- Low dielectric loss (tan δ approx. ≤ 0.003) contributes to reduced energy loss and reliable long-distance transmission.
- PE Sheath:
- Non-toxic and environmentally friendly, aligning with green building requirements.
- Excellent weathering and UV resistance; no obvious cracking or chalking even after years of outdoor exposure.
- Maintains flexibility and appearance without plasticizer-related aging, making it a better option than conventional PVC sheath in high-demand projects.
- Copper Conductor:
- Uses high-purity electrolytic copper (conductivity close to 99.97% IACS).
- Low resistance reduces heat build-up and voltage drop, enhancing overall system efficiency.
- Maintains firm and stable connections, reducing the need for frequent tightening and thermal inspections.
Standards-Driven & Widely Applicable - Ideal for Dense-Population Areas
WDZ-YJY23 is designed to align with relevant mandatory fire and environmental standards, including but not limited to:
- GB/T 19666: General requirements for flame-retardant and fire-resistant cable performance
- GB 12666: Flame-retardant and fire testing for cables and wiring
- GB 50217 and related building/installation codes for cables in high-occupancy spaces
Typical fields where these requirements apply:
- Metro systems, airports, major railway stations
- Hospitals, schools, large shopping centers
- Data centers, control rooms, and industrial sites with halogen-free requirements
Installation options include direct burial, conduit, overhead, cable trays, and tunnels, enabling WDZ-YJY23 to cover the majority of high-compliance use cases.

FAQ - WDZ-YJY23 LSZH Armored Cable
Q1: Why choose low smoke zero halogen instead of standard PVC-sheathed cables?
In a fire, PVC-based materials can produce dense, corrosive smoke and halogen acid gases, which can harm people and destroy equipment. LSZH materials greatly reduce smoke output and eliminate halogen acid gases, making escape routes more visible and limiting toxic exposure.
Q2: Is WDZ-YJY23 suitable for direct burial?
Yes. The double steel tape armoring and polyethylene outer sheath make it suitable for many direct-burial applications, as well as concealed routing in walls and underground ducts. It is designed to withstand soil pressure, settlement, and common site activities when the installation follows relevant engineering codes.
Q3: How does this cable protect sensitive equipment like servers or control systems?
Because WDZ-YJY23 uses halogen-free materials and produces less corrosive gases, it significantly lowers the risk of damage to metallic parts, printed circuit boards, and connectors during and after a fire, compared with conventional halogen-containing cables.
Q4: Can WDZ-YJY23 be used outdoors?
Yes. The PE sheath offers very good weather and UV resistance. It is suitable for both indoor and outdoor installations, including exposed runs, as long as mechanical and routing design meet relevant standards.
Q5: What flame-retardant classes are available?
Standard designs target a flame-retardant level corresponding roughly to Class B, while higher levels such as Class A can be provided on request, depending on local code and project requirements.
Q6: How do I know if WDZ-YJY23 is the right choice for my project?
If your project involves crowded spaces, enclosed environments, or strict fire and environmental audits --such as high-rise, public transportation, medical facilities, or data centers--WDZ-YJY23 is usually a strong candidate. Share your applicable standards and project conditions, and a design team can confirm suitability and recommend sizes.
