Main Advantages

1. Dual protection of flame retardancy and fire resistance with ultra-high fire safety The cable features high-standard Class B flame retardancy and fire resistance as WDZBN. It can resist flame spread and maintain circuit integrity without open circuit or breakdown under direct flame exposure, enabling short-term continuous power supply in fire conditions. Compared with ordinary flame-retardant wires, its safety level is greatly upgraded. It can effectively contain the spread of electrical fires, guarantee normal operation of emergency lighting and auxiliary fire circuits, and meet fire acceptance requirements of high-standard buildings.
2. Low-smoke zero-halogen and eco-friendly, reducing secondary hazards in fire It adopts halogen-free, heavy-metal-free and eco-friendly cross-linked insulation material which is non-toxic. In case of combustion, it generates extremely low smoke and releases no corrosive toxic gases. During fire accidents, it helps preserve evacuation visibility and avoid secondary disasters such as poisoning and corrosion, suitable for public buildings with dense crowds and strict fire protection requirements.
3. Excellent cross-linked insulation, anti-ageing and long service life It adopts high-performance radiation cross-linked polyolefin insulation with stable molecular structure, delivering outstanding high temperature resistance, oxidation resistance and anti-ageing performance. It is not easy to soften, deform or crack under full-load continuous operation. Its temperature and weather resistance outperform traditional PVC wires, greatly extending service life and reducing later circuit renovation and maintenance costs of buildings.
4. Fine wire body for convenient and efficient installation Made of high-purity solid copper conductor with precision extrusion process, the wire has smooth and neat appearance, good flexibility and strong bending resistance. It adapts to various construction scenarios including concealed conduit laying, ceiling wiring and wall trunking wiring. It features low conduit friction and good shape retention, making installation labour-saving and improving wiring efficiency for residential and commercial projects.
5. Stable electrical performance for reliable daily power distribution High-conductivity oxygen-free copper conductor has low resistance, low power loss and low temperature rise during operation. It can steadily carry loads for civil lighting, sockets and small power equipment for a long time. The insulation layer has stable voltage resistance and high dielectric strength with excellent leakage and breakdown resistance, ensuring all-day safe and stable operation of indoor low-voltage power distribution systems in buildings.

Technical Specifications

Applications

WDZBN-BYJ low-smoke zero-halogen flame-retardant fire-resistant wire is a high-end fire-safe and eco-friendly building wiring cable with solid single-core structure, designed for refined high-standard power distribution construction. It applies to concealed conduit laying, ceiling wiring, wall and floor trunking wiring inside various buildings. It is suitable for dry indoor power distribution environments and not for outdoor sun exposure or water immersion. Widely used in high-end residential communities, commercial complexes, office buildings, hospitals, schools and supporting metro buildings with critical fire protection requirements. It is mainly used for fire emergency circuits, public area lighting, civil socket power distribution and small power distribution systems requiring fire resistance, flame retardancy, environmental protection and safety. It serves as the preferred core wiring product for modern green fire-resistant buildings.
