WDZB1N-KYJY23 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.
Strong mechanical protection: Double-layer galvanized steel tape armor provides excellent resistance to compression, impact, and biological damage, making it suitable for installation in complex environments such as direct burial and tunnels.
Good temperature resistance: Cross-linked polyethylene insulation supports long-term operation at 90°C and maintains electrical functionality even under fire-resistant conditions.
Wide environmental adaptability: Halogen-free, low-smoke polyolefin sheath is resistant to moisture and UV radiation, and the armored structure is suitable for indoor, tunnel, and harsh outdoor scenarios.
Selling Points:
Integrated solution for life safety and protection: Combines fire resistance, B1-grade flame retardancy, low smoke, halogen-free properties, and steel tape armor to meet quadruple high standards, addressing comprehensive protection needs for high-safety-risk projects such as hospitals and subways.
Fully compliant product: Meets national fire resistance standards, B1-grade flame retardancy requirements, and armored mechanical protection specifications simultaneously, making it a mandatory compliance choice for public buildings, transportation hubs, and similar projects.
High-reliability design for all hazards: Integrates continuous power supply during fires with flame retardancy and smoke control, combined with armor damage resistance, providing critical support for personnel evacuation, fire rescue, and system recovery.
Flexible adaptation to ultra-high-standard scenarios: Supports customization for different fire resistance durations (e.g., 90min/120min/180min) and compatibility with various complex installation methods such as direct burial, conduit routing, and cable tray laying.
Application Range: Core safety systems in national major projects and lifeline projects, such as nuclear power plant safety control systems, subway emergency evacuation systems, airport control tower systems, data center core equipment, and government emergency command systems.
Special Notes: Class B1 flame retardant is currently the highest civilian flame retardant level in national standards; fire resistance performance meets the most stringent fire conditions; halogen-free, low smoke ensures safe evacuation during fires; double-layer armor provides top-level mechanical protection; represents the highest safety level control cable.
