返回:常見問題
電纜橋架設備的大載荷和支撐距離應小于允許載荷和支撐跨度。在選擇電纜橋架的寬度時,應留有一定的余量,以便以后添加電纜。當動力電纜和控制電纜較少時,可以使用電纜橋架裝置,但動力電纜和控制電纜應隔離,中間有隔板敷設。
The large load and support distance of cable tray equipment shall be less than the allowable load and support span. When selecting the width of the cable tray, a certain margin shall be reserved for adding cables in the future. When there are few power cables and control cables, the cable tray device can be used, but the power cables and control cables shall be isolated and laid with a partition in the middle.
電纜橋架水平敷設時,橋架之間的連接接頭應盡量設置在跨度的1/4左右。水平走線每2米固定一次,直線走線每1.5米固定一次。電纜橋架應可靠接地。例如,距離電纜橋架每隔30-50米接地一次。
When the cable tray is laid horizontally, the connecting joints between the trays shall be set at about 1 / 4 of the span as far as possible. The horizontal route shall be fixed every 2 meters and the straight route shall be fixed every 1.5 meters. The cable tray shall be reliably grounded. For example, it is grounded every 30-50m from the cable tray.
熱鍍鋅電纜橋架設備除屏蔽和防護罩外,室外設備為熱鍍鋅電纜橋架時,應在頂層安裝防護罩,避免日曬雨淋。對于焊接設備,焊縫周圍的焊縫厚度不得小于母材厚度,焊縫必須進行防腐處理。
In addition to shielding and protective cover for hot-dip galvanized cable bridge equipment, when outdoor equipment is hot-dip galvanized cable bridge, protective cover shall be installed on the top layer to avoid sun and rain. For welding equipment, the thickness of the weld around the weld shall not be less than the thickness of the base metal, and the weld must be subject to anti-corrosion treatment.
山東電纜橋架
電纜橋架的分層放置應為弱電控制電纜在上層,一般控制電纜次之,低壓電力電纜和高壓電力電纜依次下放。這種布置有利于屏蔽干擾、冷卻電力電纜和便于施工。
The layered placement of cable tray shall be that the weak current control cable is on the upper layer, followed by the general control cable, and the low-voltage power cable and high-voltage power cable are placed in turn. This arrangement is conducive to shielding interference, cooling power cables and facilitating construction.
每層熱鍍鋅電纜橋架間距為:控制電纜≥200mm電力電纜≥300mm機械化敷設電纜≥400mm。
The spacing of each layer of hot-dip galvanized cable tray is: control cable ≥ 200mm, power cable ≥ 300mm, mechanized laying cable ≥ 400mm.
電纜橋架系統平面布置圖中應標出電纜橋架的路徑走向,托盤式電纜橋架或梯式電纜橋架的規格、層數,各類彎通的位置、調高片、調寬片及電纜橋架伸縮節的設置點,支吊架的配置及各相關尺寸。
The layout plan of the cable tray system shall indicate the route of the cable tray, the specification and number of layers of the tray type cable tray or ladder type cable tray, the position of various bends, the setting points of the height adjustment piece, width adjustment piece and the expansion joint of the cable tray, the configuration of supports and hangers and various relevant dimensions.
山東電纜橋架系統剖面圖中應標注山東電纜橋架的層間間距、支吊架的層間標高、路徑走向的標高變動、支吊架的安裝方式等。電纜橋架系統設計時應優先選用標準系列產品,對工程所需的非標準件應給出詳圖及技術說明。
The cross-sectional drawing of Shandong cable tray system shall indicate the interlayer spacing of Shandong cable tray, the interlayer elevation of supports and hangers, the elevation change of path direction, the installation mode of supports and hangers, etc. Standard series products shall be preferred in the design of cable tray system, and detailed drawings and technical instructions shall be given for non-standard parts required by the project.
