【中文】防火桥架采用槽式通道结构并进行相应表面处理，帮助线缆在特定工程区域内获得更完整的外部防护，需与连接、封闭和支撑措施共同构成系统。用于消防配套、电力通道、公共建筑及重要设备区域的线缆敷设，便于线路集中管理、分区布置和后期检查；防火性能属于系统性要求，选型时应核对连接节点、盖板、支撑和封堵等配套措施。
【English】The fireproof cable tray uses a trough-type channel with appropriate surface treatment so cables gain more complete external protection in specific project zones, and must form a system with connection, enclosure and support measures. It is used for cable routing in fire protection works, power corridors, public buildings and important equipment areas, supporting centralised and zoned cable management and later inspection. Fire performance is a system-level requirement, so connection details, covers, supports and sealing measures must be checked when selecting.
