【中文】大跨距桥架以侧边承载构件和横向支撑共同形成开放式通道，适用于需要跨越较长区段的线缆敷设，结构便于观察线缆状态，也有利于分层整理与维护。用于工业厂房、管廊、设备区和长距离机电通道中的电力、控制及通信线缆敷设，选型时应结合线缆分布、支点布置、检修空间及环境因素确定最终结构。
【English】The long-span cable tray combines side carrying members and transverse supports into an open channel for routes that must cross long sections. Its structure makes cable condition easy to observe and helps with layered organisation and maintenance. It is used for power, control and communication cables in industrial plants, utility tunnels, equipment areas and long-distance services corridors. Selection should consider cable layout, support spacing, maintenance space and environmental factors.
