大跨距橋架在大理地區安裝中有什么要求

        大跨距橋架相對于一般的電纜橋架來說，生產和安裝要求要高一些，大理作為云南比較落后的市，本地很少有大理橋架廠家，更別說大跨距橋架生產，一般都是從昆明購買，同時大理橋架安裝也沒有昆明地區規范，當前大跨距橋架在大理地區安裝種有什么要求呢？

大理橋架在選購廠家設計選型過程應根據弱電各個系統纜顯得類型、數量，合理選定適用的橋架。

        如果和大跨距橋架合用時，應將電力電纜和弱電電纜各直一側，中間采用隔板分隔；大理大跨距電纜與其它低電壓電纜合用橋架時，應嚴格執行選擇具有外屏蔽層的弱電系統的弱電電纜，避免相互間的干擾。

        大理電纜橋架不得與其它管道等設施共用一個立柱(支架)。大理不銹鋼橋架對于腐蝕性環境，大理橋架選擇生產廠家應選用具有合適的耐防腐蝕層處理的電纜橋架。在有強烈振動及有可能遭受嚴重機械損傷的場所，不宜架設電纜橋架。

What are the requirements for the installation of long span bridges in Dali area?

One

Compared with the general cable bridge, the production and installation requirements of long-span bridge are higher. As a relatively backward city in Yunnan, there are few manufacturers of Dali bridge, let alone the production of long-span bridge, which are generally purchased from Kunming. At the same time, the installation of Dali bridge does not have the specifications of Kunming area. What are the requirements for the installation of the bridge in Dali?

In the design and selection process of Dali Bridge Frame, the suitable bridge should be selected reasonably according to the type and quantity of weak current system cables.

If the power cable and the weak current cable are used together with the long-span bridge, they should be separated by a separator in the middle. When the large-span cable and other low-voltage cable are used together, the weak current cable of the weak current system with an outer shield layer should be strictly selected to avoid mutual interference.

Dali cable bridge should not share a column (bracket) with other pipes and other facilities. For corrosive environment of Dali stainless steel bridge, the manufacturer of Dali bridge should choose the cable bridge with suitable anti-corrosion coating treatment. It is not suitable to erect cable bridge in places where strong vibration and serious mechanical damage may occur.
