電氣電纜橋架

一、電纜橋架的類型:
1、 Type of cable tray:
電纜橋架按照結構形式可以分為槽式、托盤式和梯架式、網格式等。
Cable trays can be divided into trough type, tray type, ladder type and grid type according to the structure.
二、電纜橋架的選擇:
2、 Selection of cable tray:
一般情況下,電氣常常采用梯架式電纜橋架,主要是為了方便散熱。而自控常常采用槽式和托盤式電纜橋架,因為自控的電纜發熱較少、主要防止干擾信號。
In general, ladder type cable tray is often used for electrical purposes, mainly to facilitate heat dissipation. However, trough and tray cable trays are often used for automatic control, because the cables of automatic control are less heated and mainly used to prevent interference signals.
根據電纜橋架應用,對于常規室內、外場所一般采用鍍鋅電纜橋架;對于腐蝕比較嚴重的場所,一般采用鋁合金電纜橋架或玻璃鋼電纜橋架。在一般建筑物內,采用輕型橋架,跨度采用2-3m的電纜橋架,方便安裝和施工;而廠房里,由于柱距較大常常采用大跨距電纜橋架。
According to the application of cable tray, galvanized cable tray is generally used for conventional indoor and outdoor field stations; For places with serious corrosion, aluminum alloy cable tray or glass fiber reinforced plastic cable tray is generally used. In general buildings, light bridges are used, and cable bridges with a span of 2-3m are used to facilitate installation and construction; In the factory building, large span cable trays are often used due to large column spacing.
三、電纜橋架的荷載:
3、 Load of cable tray:
電纜橋架的荷載由三部分組成:一個是電纜橋架本身重量,二是電纜的重量,三是施工人員的重量。
The load of cable bridge is composed of three parts: one is the weight of cable bridge itself, the other is the weight of cable, and the third is the weight of construction personnel.
四、電纜橋架的間距:
4、 Spacing of cable tray:
當電纜橋架水平上下敷設時(不是交叉),電氣電纜橋架的間距一般考慮300mm。和儀表、電信的電纜橋架距離要看相關的標準。
When the cable tray is laid horizontally up and down (not cross), the spacing of electrical cable tray is generally considered as 300mm. The distance between cable tray and instrument and telecommunication shall be subject to relevant standards.

五、電纜橋架的敷設:
5、 Laying of cable tray:
電氣電纜橋架敷設時,應考慮和附近各種管線的距離要求和安裝位置的要求,不能敷設在熱力管線的上面。注意電纜橋架的彎曲半徑和電纜的彎曲半徑。
When laying the electrical cable tray, the distance requirements and installation position requirements of various nearby pipelines shall be considered, and the cable tray cannot be laid above the thermal pipeline. Pay attention to the bending radius of cable tray and cable.
