电缆桥架是一种用于保护电缆的常见工具设备,很多工程在使用济南电缆桥架时由于使用规范和相关知识的不够了解,往往会导致设备效果打折扣。那么,电缆桥架的使用你要知道什么事项呢?
Cable tray is a common tool and equipment used to protect cables. When using Jinan cable tray in many projects, due to lack of understanding of the use specifications and relevant knowledge, the equipment effect is often reduced. So, what do you need to know about the use of cable tray?
1、电缆桥架装置的较大载荷支撑间距应小于允许载荷和支撑跨距。
1. The support spacing of large load of cable tray device shall be less than the allowable load and support span.
2、选择电缆桥架宽度时应留有一定的备用空位,以便为今后增添电缆用。
2. When selecting the width of cable tray, certain spare space shall be reserved for the future use of cables.
3、当电力电缆和控制电缆较少时,可同一电缆桥架安装,但中间要用隔板将电力电缆和控制电缆隔开敷设。
3. When there are few power cables and control cables, they can be installed on the same cable bridge, but the power cables and control cables should be separated and laid by partitions.
4、电缆桥架水平敷设时,桥架之间的连接头应尽量设置在跨距的1/4左右处,水平走向的电缆每隔2米左右固定一下,垂直走向的电缆每隔1.5米左右固定一下。
4. When the cable tray is laid horizontally, the connector between the cable trays should be set at about 1/4 of the span as far as possible, the cable with horizontal direction should be fixed at about 2 meters, and the cable with vertical direction should be fixed at about 1.5 meters.

5、电缆桥架装置应有可靠接地。如利用桥架作为接地干线,应将每层桥架的端部用16mm2软铜线联接(并联)起来,与总接地干线相通,长距离的电缆桥架每隔30--50米接地一次。
5. The cable bridge device shall be reliably grounded. If the cable tray is used as the main grounding line, the end of each layer of cable tray shall be connected (connected in parallel) with 16mm2 flexible copper wire to connect with the main grounding line. Long-distance cable tray shall be grounded every 30-50 meters.
6、电缆桥架装置除需屏蔽装保护罩外,在室外安装时应在其加装保护罩,防止日晒雨淋,对如需焊接安装时,焊件四周的焊缝厚度不得小于母材的厚度,焊口必须防腐处理。缆在桥架内横断面的填充率:电力电缆不应大于40%;控制电缆不应大于50%,对于弱电线路可到60%。
6. In addition to shielding and protective cover, the cable bridge device shall be installed with protective cover on its top layer during outdoor installation to prevent the sun and rain. If welding and installation is required, the weld thickness around the weldment shall not be less than the thickness of the base metal, and the weld joint must be subject to anti-corrosion treatment. The filling rate of the cable in the cross section of the bridge: the power cable shall not be greater than 40%; The control cable shall not be more than 50%, and it can reach 60% for weak current lines.
此外选择电缆桥架宽度时应留有一定的备用空位、电缆桥架装置应有可靠接地以及电缆桥架装置除需屏蔽装保护罩外,在室外安装时应在其加装保护罩。
In addition, certain spare space shall be reserved when selecting the width of the cable bridge, the cable bridge device shall be reliably grounded, and the cable bridge device shall be equipped with a protective cover on its top layer during outdoor installation.
