槽式桥架是采用全封闭槽体结构的桥架产品，由槽底、槽盖与配套连接件组成，是弱电系统、精密控制线缆敷设场景的主流选型。其核心技术原理是通过封闭的金属壳体形成电磁屏蔽空间，有效降低外部电磁环境对内部线缆的信号干扰，同时阻挡粉尘、水汽、油污等外界介质接触线缆，延缓绝缘层老化。

Slot type cable tray is a cable tray product that adopts a fully enclosed slot structure, consisting of a slot bottom, a slot cover, and supporting connectors. It is the mainstream selection for weak current systems and precision control cable laying scenarios. The core technical principle is to form an electromagnetic shielding space through a closed metal shell, effectively reducing the signal interference of external electromagnetic environment on internal cables, while blocking external media such as dust, water vapor, and oil from contacting the cables, and delaying the aging of the insulation layer.

从适用场景来看，槽式桥架尤其适配计算机电缆、通信电缆、热电偶电缆及高灵敏度控制电缆的敷设，在数据中心机房、自动化生产线、医疗精密设备配电等场景中应用广泛。针对不同腐蚀等级的环境，槽式桥架可搭配镀锌、喷塑、热浸锌、不锈钢等多种表面处理工艺，其中防火喷塑槽式桥架可同时实现屏蔽与防火双重功能，满足高消防等级场景需求。

From the perspective of applicable scenarios, trough type cable trays are particularly suitable for laying computer cables, communication cables, thermocouple cables, and high-sensitivity control cables. They are widely used in data center rooms, automated production lines, medical precision equipment distribution, and other scenarios. For environments with different corrosion levels, trough type cable trays can be equipped with various surface treatment processes such as galvanizing, spray coating, hot-dip galvanizing, stainless steel, etc. Among them, fireproof spray coating trough type cable trays can achieve dual functions of shielding and fire prevention, meeting the needs of high fire protection level scenarios.

在结构设计上，标准槽式桥架常规宽度覆盖 50mm 至 800mm，高度覆盖 50mm 至 200mm，可根据线缆数量与直径定制截面尺寸；槽体拼接采用专用连接片与螺栓固定，配套弯通、三通、四通等构件，适配复杂布线走向。

In terms of structural design, standard trough type cable trays typically cover a width of 50mm to 800mm and a height of 50mm to 200mm. The cross-sectional dimensions can be customized according to the number and diameter of cables; The slot body splicing adopts dedicated connecting pieces and bolts for fixation, and is matched with components such as bends, tees, and crosses to adapt to complex wiring routes.
