大跨距橋架在大理地區(qū)安裝中有什么要求

        大跨距橋架相對(duì)于一般的電纜橋架來(lái)說(shuō)，生產(chǎn)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(shuō)大跨距橋架生產(chǎn)，一般都是從昆明購(gòu)買，同時(shí)大理橋架安裝也沒(méi)有昆明地區(qū)規(guī)范，當(dāng)前大跨距橋架在大理地區(qū)安裝種有什么要求呢？

大理橋架在選購(gòu)廠家設(shè)計(jì)選型過(guò)程應(yīng)根據(jù)弱電各個(gè)系統(tǒng)纜顯得類型、數(shù)量，合理選定適用的橋架。

        如果和大跨距橋架合用時(shí)，應(yīng)將電力電纜和弱電電纜各直一側(cè)，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(shí)，應(yīng)嚴(yán)格執(zhí)行選擇具有外屏蔽層的弱電系統(tǒng)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(shè)施共用一個(gè)立柱(支架)。大理不銹鋼橋架對(duì)于腐蝕性環(huán)境，大理橋架選擇生產(chǎn)廠家應(yīng)選用具有合適的耐防腐蝕層處理的電纜橋架。在有強(qiáng)烈振動(dòng)及有可能遭受嚴(yán)重機(jī)械損傷的場(chǎng)所，不宜架設(shè)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.
