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.

我們知道的是地鐵隧道本身就是施工難度比較高，造價會比較高，安裝難度如果比較高，這樣就會大大提升熱鍍鋅電纜橋架的安裝造價，所以說我們選擇的時候，一定要去看一下電纜橋架跨距尺寸精度到底是怎么樣的.

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滿足要求的，或者說它的尺寸精度是比較好的，這樣的一個產(chǎn)品是值得我們?nèi)ミx擇的，如果它的尺寸精度不怎么樣，或者說它的曾經(jīng)都沒有辦法去達(dá)到我們大家的理想水平，就說明這個產(chǎn)品是不值得我們?nèi)ミx擇了。

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.

當(dāng)你去選擇一個產(chǎn)品的時候，一定要去根據(jù)熱鍍鋅電纜橋架尺寸精度，包含它的具體情況去進行選擇，把這些細(xì)節(jié)東西搞清楚，將來才是能夠去達(dá)到一個比較好的效果，如果細(xì)節(jié)上面搞不清楚，后患無窮。

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.
