B1-Class Flame-Retardant Wires and Cables

B1-Class Flame-Retardant Wires and Cables

Models: WDZB1-BYJ-125, WDZB1-YJY

B1-class flame-retardant wires and cables combine the advantages of halogen-free low-smoke cables with stricter requirements for heat release, burning rate, and smoke production, making them ideal for densely populated areas like subways and schools.

• 1.Low Smoke: When burned, only faint water vapor is released, with a minimum light transmittance of ≥60%.
• 2.Non-Toxic: Contains no harmful substances; the pH value of combustion gases is ≥4.3.
• 3.Flame Retardant: Structural design and material selection achieve B1-class flame retardancy, controlling heat release, burning rate, and smoke production.
