Product Feature And Application
To prevent fire from spreading along the circuit, select ZR-BVR. To maintain critical circuit operation during a fire, select NH-BVR. In densely populated areas or escape routes, prioritize WDZ-BYJR.
Fire-rated electrical wires are frequently used in the following scenarios:
■ Temporary power distribution systems on construction sites:
ZR-BVRs are used for internal wiring in mobile distribution boxes, meeting the flexibility requirements of frequent disassembly and assembly while providing basic fire resistance.
■ Fire alarm linkage systems in high-rise residential buildings:
NH-BVRs are installed between emergency lighting, fire alarm controllers, and detectors to ensure uninterrupted signal and power supply during a fire.
■ Ceiling wiring in commercial complexes:
Ceiling conduits often have many bends; ZR-BVRs or WDZ-BYJRs are recommended to balance ease of installation with public space safety requirements.
■ Internal wiring in industrial control cabinets:
ZR-BVRs are recommended due to their flexibility, facilitating wiring in confined spaces, and their flame-retardant properties, enhancing overall equipment safety.
FAQ
Q: How to distinguish the model of fire-rated electrical wire?
A: Fire-rated BVR wires are mainly distinguished by their model prefixes (such as ZR, NH, WDZ) to determine their flame retardancy, fire resistance, and applicable scenarios. ZR-BVR focuses on preventing the spread of flames, NH-BVR ensures continuous power supply during a fire, and WDZ-BYJR takes into account low smoke and halogen-free environmental characteristics. Each type is suitable for electrical wiring environments with different safety levels.
