电缆桥架在使用中短路是怎么回事呢？实际上电缆桥架在使用中常见的问题是短路，可能是电缆内部短路，也可能是电缆被烧坏。下面就来简单讲讲吧。

What is the short circuit of cable tray in use? In fact, the common problem of cable tray in use is short circuit, which may be the internal short circuit of the cable or the burning of the cable. Let's talk about it briefly.

一般来说，电缆质量太低。 济南电缆桥架在使用过程中会膨胀和收缩。由于环境温度的变化，如钢索桥会热胀冷缩。室外桥架的功能受温度影响较大，使用中需要注意高温风机的温度变化。

Generally speaking, the cable quality is too low. Jinan cable tray will expand and contract during use. Due to the change of ambient temperature, such as steel cable bridge, it will expand and contract. The function of outdoor bridge is greatly affected by temperature, so it is necessary to pay attention to the temperature change of high-temperature fan during use.

此外电缆桥架安装前，应根据建筑物的结构特点、计算荷载、桥架的尺寸和挠度确定合适的跨度，既要满足要求的荷载挠度，又要考虑安装的方便性。

In addition, before the installation of the cable tray, the appropriate span shall be determined according to the structural characteristics of the building, the calculated load, the size and deflection of the tray, which shall not only meet the required load deflection, but also consider the convenience of installation.

桥梁安装的准备工作是在两个桥台之间搭设脚手架，铺设坡道作为气动球阀钢桥的搭设平台。ZL50C装载机从两侧桥台到施工道路平整场地。画出场地线，标明桥梁所有构件、配件和架设工具的堆放位置。

The preparation work for bridge installation is to erect scaffold between two abutments and lay ramp as the erection platform of pneumatic ball valve steel bridge. ZL50C loader is used to level the site from the abutments on both sides to the construction road. Draw the site ground wire and indicate the stacking position of all components, fittings and erection tools of the bridge.

通过测量和放线确定岩石、辊和座板的位置。测量桥梁中线桩、岩石桩、滚桩和台座桩的标高。桥梁中线桩应尽可能测量到对岸的鼻端。

Determine the position of rock, roller and seat plate through measurement and setting out. Measure the elevations of bridge centerline piles, rock piles, rolling piles and abutment piles. The bridge centerline pile shall be measured to the nose of the opposite bank as far as possible.

桥梁架设所需的配件、架设工具及各种机械设备准备齐全，用5t自卸汽车运至施工现场，进行局部分类堆放。工艺管道可以考虑室外安装，但需要注意的是，电缆桥架应沿易燃、易爆、低风险一侧安装。

Accessories, erection tools and various mechanical equipment required for bridge erection shall be fully prepared and transported to the construction site by 5T dump truck for partial stacking. The process pipeline can be installed outdoors, but it should be noted that the cable tray should be installed along the flammable, explosive and low-risk side.

在使用中，需要找到合适类型的电缆桥架，并按照相关规定使用。不同类型的电缆桥架有不同的应用范围，你要根据自己的需求找到合适的。不要盲目选择使用，这样不仅不能保证使用效果，还会缩短桥梁的使用寿命。更多相关事项就来我们网站 //www.comprepyme.com咨询吧！

In use, it is necessary to find a suitable type of cable tray and use it according to relevant regulations. Different types of cable trays have different application ranges. You should find the right one according to your own needs. Do not blindly choose to use, which will not only not ensure the use effect, but also shorten the service life of the bridge.
