在电气工程领域，电缆桥架堪称电力与信号传输的 “生命线载体”，其质量优劣绝非小事，劣质电缆桥架带来的麻烦，足以让工程陷入困境，甚危及生命财产。

　　In the field of electrical engineering, cable trays can be regarded as the "lifeline carrier" of power and signal transmission. The quality of cable trays is not a small matter. The trouble caused by poor quality cable trays can lead to difficulties in engineering and even endanger the safety of life and property.

　　从项目施工阶段说起，选用劣质电缆桥架，就如同埋下一颗 “定时炸弹”。一些厂家为压缩成本，在板材厚度上偷工减料，标称 2 毫米厚的桥架，实际可能仅有 1.2 毫米甚更薄。如此一来，桥架的承重能力大打折扣，在安装过程中，稍微受力就容易发生弯曲变形。想象一下，施工人员正有条不紊地敷设电缆，却突然发现桥架因无法承受重量而扭曲，不仅安装进度被迫中断，已敷设好的部分电缆也可能因桥架变形而受损，前期投入的人力、物力瞬间付诸东流，施工成本大幅增加，工期更是被无限拉长。

　　Starting from the construction phase of the project, choosing low-quality cable trays is like planting a 'time bomb'. Some manufacturers cut corners on the thickness of the boards in order to reduce costs. A bridge with a nominal thickness of 2 millimeters may actually be only 1.2 millimeters or even thinner. In this way, the load-bearing capacity of the bridge is greatly reduced, and during installation, it is easy to bend and deform under slight stress. Imagine a construction worker laying cables in an orderly manner, only to suddenly discover that the cable tray is twisted due to the inability to bear weight. Not only is the installation progress forced to be interrupted, but the already laid cables may also be damaged due to the deformation of the cable tray. The manpower and material resources invested in the early stage are instantly diverted to the east, resulting in a significant increase in construction costs and an infinite extension of the construction period.

　　进入使用阶段，劣质电缆桥架的弊端愈发凸显。由于材质不佳，其耐腐蚀性能极差。在普通室内环境下，或许短时间内还能勉强维持，但一旦处于潮湿的地下室、沿海高盐雾地区，或是化工企业等有腐蚀性气体的特殊环境中，几个月时间，桥架便开始生锈腐蚀。先是表面出现斑驳锈点，接着锈迹蔓延，镀锌层或涂层起泡、剥落，直桥架结构被破坏。当桥架被锈穿，失去对电缆的有效支撑与保护，电缆绝缘层暴露在外，极易因受潮、受腐蚀而损坏，引发漏电、短路等严重故障。

　　As we enter the usage stage, the drawbacks of inferior cable trays become increasingly prominent. Due to poor material quality, its corrosion resistance is extremely poor. In a normal indoor environment, it may be able to barely maintain for a short period of time, but once it is in a damp basement, high salt spray area along the sea, or a special environment with corrosive gases such as chemical enterprises, the bridge frame begins to rust and corrode after a few months. Firstly, there are mottled rust spots on the surface, followed by the spread of rust, blistering and peeling of the galvanized layer or coating, until the bridge structure is damaged. When the cable tray is corroded and loses effective support and protection for the cable, the insulation layer of the cable is exposed and easily damaged due to moisture and corrosion, causing serious faults such as leakage and short circuit.

　　这些故障所带来的影响是的。对企业生产而言，一旦因电缆故障导致停电停产，每一分钟的损失都难以估量。生产线停滞，设备空转，订单交付延迟，不仅要面临客户的巨额索赔，企业信誉也会遭受重创，多年积累的市场口碑毁于一旦。以一家电子制造企业为例，因车间内劣质电缆桥架引发短路停电，一次事故就造成了数十万元的直接经济损失，包括产品报废、设备维修费用等，间接损失如客户流失、后续订单减少等更是难以统计。

　　The impact of these faults is comprehensive. For enterprise production, once a power outage or shutdown is caused by cable failure, the loss of every minute is difficult to estimate. The production line stagnates, equipment runs idle, and order delivery is delayed. Not only will it face huge claims from customers, but the company's reputation will also be severely damaged, and years of accumulated market reputation will be destroyed. Taking an electronic manufacturing enterprise as an example, a short circuit and power outage caused by poor quality cable trays in the workshop resulted in direct economic losses of hundreds of thousands of yuan in one accident, including product scrapping, equipment maintenance costs, etc. Indirect losses such as customer loss and subsequent order reduction are difficult to calculate.

　　在人员方面，劣质电缆桥架引发的电气事故，可能对现场人员造成直接伤害。漏电事故发生时，周边人员一旦接触到带电区域，便有触电风险，危及生命；而短路引发的火灾，火势蔓延迅速，在封闭空间内，高温浓烟还会造成人员窒息。在一些老旧建筑改造项目中，因使用了不符合标准的劣质桥架，电气火灾时有发生，给居民生命财产带来极大威胁。

　　In terms of personnel safety, electrical accidents caused by poor quality cable trays may directly harm on-site personnel. When a leakage accident occurs, there is a risk of electric shock to surrounding personnel once they come into contact with the live area, which endangers their life safety; The fire caused by a short circuit spreads rapidly, and in enclosed spaces, high temperatures and thick smoke can cause suffocation of personnel. In some renovation projects of old buildings, electrical fires often occur due to the use of substandard and inferior cable trays, posing a great threat to the safety of residents' lives and property.
