电气电缆桥架

一、电缆桥架的类型:
1、 Type of cable tray:
电缆桥架按照结构形式可以分为槽式、托盘式和梯架式、网格式等。
Cable trays can be divided into trough type, tray type, ladder type and grid type according to the structure.
二、电缆桥架的选择:
2、 Selection of cable tray:
一般情况下,电气常常采用梯架式电缆桥架,主要是为了方便散热。而自控常常采用槽式和托盘式电缆桥架,因为自控的电缆发热较少、主要防止干扰信号。
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.
根据电缆桥架应用,对于常规室内、外场所一般采用镀锌电缆桥架;对于腐蚀比较严重的场所,一般采用铝合金电缆桥架或玻璃钢电缆桥架。在一般建筑物内,采用轻型桥架,跨度采用2-3m的电缆桥架,方便安装和施工;而厂房里,由于柱距较大常常采用大跨距电缆桥架。
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、电缆桥架的荷载:
3、 Load of cable tray:
电缆桥架的荷载由三部分组成:一个是电缆桥架本身重量,二是电缆的重量,三是施工人员的重量。
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、电缆桥架的间距:
4、 Spacing of cable tray:
当电缆桥架水平上下敷设时(不是交叉),电气电缆桥架的间距一般考虑300mm。和仪表、电信的电缆桥架距离要看相关的标准。
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、电缆桥架的敷设:
5、 Laying of cable tray:
电气电缆桥架敷设时,应考虑和附近各种管线的距离要求和安装位置的要求,不能敷设在热力管线的上面。注意电缆桥架的弯曲半径和电缆的弯曲半径。
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.
