玻璃钢电缆桥架的三大特性之一，玻璃钢电缆桥架远比想象的要结实，看似有的玻璃钢电缆桥架软，其实是柔韧性更好，但是往往会被人们认为是质量不好的一种表现;玻璃钢电缆桥架的三大特性之二，玻璃钢电缆桥架在夏季要比冬季更加的结实耐用，这是由于玻璃钢的特性所决定的，所以在购买的时候也应该考虑到季节的因素;玻璃钢电缆桥架的三大特性之三，看似结实的玻璃钢电缆桥架未必结实，一定要通过实践后才能得出终结论。
One of the three characteristics of GRP cable tray is that GRP cable tray is far stronger than expected. It seems that some GRP cable trays are soft, but in fact, they have better flexibility, but they are often considered as a performance of poor quality. Two of the three characteristics of GRP cable tray is that GRP cable tray is stronger and more durable in summer than in winter, which is due to the fact that GRP cable tray is stronger and more durable in summer than in winter The characteristics of steel determine, so the factors of season should also be taken into account when purchasing; three of the three characteristics of glass fiber reinforced plastic cable bridge, the seemingly solid glass fiber reinforced plastic cable bridge may not be solid, it must be concluded through practice.
画出电缆桥架平、剖面图，局部部位还应汇出空间图，开列材料表确定安装方式：根据场所的设置条件确定桥架的固定方式，选择悬吊式、直立式、侧壁式或是混合式，连接件和紧固件一般是配套供应，此外，根据桥架结构选择相应的改版。确定桥架的宽度：根据布放电缆条数、电缆直径及电缆的间距来确定汇线桥架的型号、规格，托臂的长度，支柱的长度、间距，桥架的宽度和层数。
Draw out the plan and section drawing of cable bridge, and draw out the space drawing for some parts, and list the material list to determine the installation mode: determine the fixed mode of cable bridge according to the setting conditions of the site, select the suspension type, vertical type, side wall type or hybrid type, generally, the connectors and fasteners are supplied with sets, in addition, select the corresponding revision according to the bridge structure. Determine the width of the cable tray: determine the model and specification of the cable tray, the length of the support arm, the length and spacing of the column, the width and number of layers of the cable tray according to the number of cables laid, the diameter of the cable and the spacing of the cables.
