电缆桥架设备的大载荷和支撑距离应小于允许载荷和支撑跨度。在选择电缆桥架的宽度时,应留有一定的余量,以便以后添加电缆。当动力电缆和控制电缆较少时,可以使用电缆桥架装置,但动力电缆和控制电缆应隔离,中间有隔板敷设。
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.
电缆桥架水平敷设时,桥架之间的连接接头应尽量设置在跨度的1/4左右。水平走线每2米固定一次,直线走线每1.5米固定一次。电缆桥架应可靠接地。例如,距离电缆桥架每隔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.
热镀锌电缆桥架设备除屏蔽和防护罩外,室外设备为热镀锌电缆桥架时,应在顶层安装防护罩,避免日晒雨淋。对于焊接设备,焊缝周围的焊缝厚度不得小于母材厚度,焊缝必须进行防腐处理。
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.
山东电缆桥架
电缆桥架的分层放置应为弱电控制电缆在上层,一般控制电缆次之,低压电力电缆和高压电力电缆依次下放。这种布置有利于屏蔽干扰、冷却电力电缆和便于施工。
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.
每层热镀锌电缆桥架间距为:控制电缆≥200mm电力电缆≥300mm机械化敷设电缆≥400mm。
The spacing of each layer of hot-dip galvanized cable tray is: control cable ≥ 200mm, power cable ≥ 300mm, mechanized laying cable ≥ 400mm.
电缆桥架系统平面布置图中应标出电缆桥架的路径走向,托盘式电缆桥架或梯式电缆桥架的规格、层数,各类弯通的位置、调高片、调宽片及电缆桥架伸缩节的设置点,支吊架的配置及各相关尺寸。
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.
山东电缆桥架系统剖面图中应标注山东电缆桥架的层间间距、支吊架的层间标高、路径走向的标高变动、支吊架的安装方式等。电缆桥架系统设计时应优先选用标准系列产品,对工程所需的非标准件应给出详图及技术说明。
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.
