Compared with other cases, the support products used in subway tunnels have higher requirements on the quality of cable bridge span. Why do you say that? Because the environment of this product is relatively special, and it is quite different from the outdoor cable tray.

我们知道的是地铁隧道本身就是施工难度比较高，造价会比较高，安装难度如果比较高，这样就会大大提升热镀锌电缆桥架的安装造价，所以说我们选择的时候，一定要去看一下电缆桥架跨距尺寸精度到底是怎么样的.

What we know is that the subway tunnel itself is relatively difficult to construct, and the cost will be relatively high. If the installation difficulty is relatively high, it will greatly increase the installation cost of hot-dip galvanized cable bridge. Therefore, when we choose, we must see how the span size accuracy of cable bridge is

如果它的尺寸精度是满足要求的，或者说它的尺寸精度是比较好的，这样的一个产品是值得我们去选择的，如果它的尺寸精度不怎么样，或者说它的曾经都没有办法去达到我们大家的理想水平，就说明这个产品是不值得我们去选择了。

If its dimensional accuracy meets the requirements, or its dimensional accuracy is relatively good, such a product is worthy of our choice. If its dimensional accuracy is not good, or it has no way to reach our ideal level, it means that this product is not worth our choice.

当你去选择一个产品的时候，一定要去根据热镀锌电缆桥架尺寸精度，包含它的具体情况去进行选择，把这些细节东西搞清楚，将来才是能够去达到一个比较好的效果，如果细节上面搞不清楚，后患无穷。

When you choose a product, you must choose according to the size accuracy of hot-dip galvanized cable tray, including its specific situation, and make clear these details. Only in the future can you achieve a better effect. If you don't make clear the details, there will be endless trouble.
