WDZB1N-KYJ Strong environmental adaptability Control Cable

Advantages:
Dual performance of fire resistance and B1-grade flame retardancy: Passes GB/T 19666 fire resistance tests and GB 31247 B1-grade flame retardancy tests, ensuring circuit integrity during fires while significantly suppressing flame spread and smoke toxicity.
Environmentally friendly, low smoke, halogen-free: Emits minimal smoke and releases no corrosive halogen acid gases during combustion, maximizing personnel evacuation safety and equipment protection.
Good temperature resistance: Cross-linked polyethylene insulation supports long-term operation at 90°C and maintains electrical functionality even under fire-resistant conditions.
High electrical reliability: Dual protection from fire-resistant and insulation layers ensures stable signal transmission before and after a fire.
Moderate environmental adaptability: The halogen-free, low-smoke sheath is resistant to moisture and UV radiation, suitable for indoor and safety-sensitive environments.
Selling Points:
Core cable for life safety systems: Combines fire resistance, B1-grade flame retardancy, and low smoke, halogen-free properties to meet triple high standards, making it suitable for critical lifeline systems such as fire alarms and emergency lighting.
Dual compliance with mandatory standards: Meets national fire resistance standards and B1-grade flame retardancy requirements, making it an essential choice for high-risk projects such as hospitals, subways, and tunnels.
Comprehensive disaster protection design: Balances continuous power supply during fires with initial flame retardancy and smoke control, providing critical time for personnel evacuation and rescue.
Flexible adaptation to high-standard scenarios: Customizable for different fire resistance durations (e.g., 90min/120min/180min) to match the special needs of super high-rise buildings, transportation hubs, and other demanding environments.
Application Range: Places with the highest safety requirements where life safety is crucial, such as subway emergency systems, airport emergency command centers, hospital intensive care units, nuclear power plant safety control rooms, and government emergency command centers.
Special Notes: Class B1 flame retardant is currently the highest civilian flame retardant level in national standards; fire resistance performance meets harsh 750℃~800℃, 90-minute test requirements; halogen-free, low smoke ensures personnel safety during fires; ideal choice for lifeline projects.
