WDZB1N--YJY23 Environmental protection and safety XLPE Insulated and Sheathed Power Cable

Quadruple Protection Ultimate Combination:
Fire Resistance (N): Ensures continuous power supply to critical circuits during a fire, serving as the "lifeline" of fire protection systems.
Top-Tier Flame Retardancy (B1): Maximizes prevention of flame propagation along the cable, reducing the risk of fire spread.
Environmental Safety (WD): Emits no toxic halogen acid gases and produces minimal smoke during combustion, ensuring safety for evacuation and rescue operations.
Mechanical Protection (23): Steel tape armor resists soil pressure, impacts, and damage from rodents and pests during direct burial.
Extreme Reliability Design: Specifically engineered for the most hazardous scenarios where both fire and physical damage may occur simultaneously, such as fires in underground passages.

High-Performance Costs:
Extremely High Cost: Materials (mica tape, specialized polyolefins) and processes are highly complex, making it one of the most expensive cable types on the market.
High Installation Difficulty: Large outer diameter, heavy weight, and extreme rigidity make bending and installation extremely challenging, requiring professional teams.
High Thermal Resistance: The fire-resistant layer and armor affect heat dissipation, resulting in significantly lower current-carrying capacity compared to non-fire-resistant cables of the same cross-section. Strict correction must be applied during design and selection.
Application Scope:
Used for "lifeline" circuits that power critically important fire protection facilities, as mandated by the highest-level national fire safety regulations, and must be directly buried or installed in underground/tunnel environments under significant pressure risks.

Product News

Conductor	Copper, specially stranded. Covered with double-layer mica tape or equivalent mineral-insulated fire-resistant layer.
Insulation	Cross-linked polyethylene (XLPE), long-term operating temperature 90°C.
Inner sheath	Polyolefin (halogen-free).
Armor layer	Double-layer galvanized steel tape, providing extremely high compressive strength.
Outer sheath	Polyethylene (PE) or polyolefin (halogen-free).
Rated voltage	0.6/1 kV (mainstream).
Long-term operating temperature	+90°C (Note- Due to the thermal insulation of the fire-resistant layer, the actual current-carrying capacity requires correction, typically multiplied by a factor of 0.7–0.85).
Short-circuit temperature	+250°C (5 seconds).
Fire resistance performance	Core. Complies with GB/T 19216.21 (IEC 60331-1) testing, common rating- continuous power supply for 90/180 minutes under 950°C flame (e.g., NH-IA90).
Combustion performance rating	B1 grade (GB 31247). Must pass a full set of stringent tests, including combustion calorific value, heat release rate, smoke density, smoke toxicity, etc.
Halogen-free and low-smoke performance	pH ≥ 4.3, conductivity ≤ 10 μS/mm; smoke density and light transmittance meet B1 grade requirements.
Minimum bending radius	Very large (multi-core ≥ 12D–15D, varies with structure).
