安装铝合金桥架容易出现哪些问题?

铝合金桥架在安装的时候需要考虑到电缆的走向以及细节处理问题,而且供与电缆安装的桥架种类各式各样,每种电缆桥架也有着不同的安装特点。

When installing aluminum alloy cable trays, it is necessary to consider the direction and details of the cables, and there are various types of cable trays available for cable installation, each with different installation characteristics.

1.接地跨接线在桥架两侧随意安装或漏跨接,接地跨接线不设在显眼侧。接地跨接线的线鼻与爪形垫片压接顺序装反,有的未设爪形垫片,镀锌桥架接地螺栓未有防松垫圈。

1. Grounding jumper wires should be installed or omitted on both sides of the bridge, and should not be placed on the conspicuous side. The crimping sequence of the wire nose and claw washer of the grounding jumper is reversed, and some do not have claw washers. The grounding bolts of the galvanized bridge do not have anti loosening washers. 

2.电缆桥架与托架间未固定,桥架支架未做接地跨接线,穿越防火分区未做防火封堵。

2. The cable tray and bracket are not fixed, the tray support is not grounded, and there is no fireproof sealing when passing through the fire compartment.

3.铝合金桥架与钢支架间未做防电化腐蚀的绝缘处理。桥架弯头、三通等不使用与桥架配套的成品配件,而是现场加工制作,加工质量不符合规范要求。

3. The aluminum alloy bridge and steel bracket have not been insulated to prevent electrochemical corrosion. Bridge bends, tees, and other accessories that are not matched with the bridge are not used, but are processed and manufactured on site, and the processing quality does not meet the standard requirements.

4.螺杆吊架安装桥架时,未按规范要求设置防晃支架,钢支架未按防腐要求施工。

When installing the cable tray with screw hangers, anti sway brackets were not set up according to the specifications, and the steel brackets were not constructed according to anti-corrosion requirements.

5.金属电缆桥架及其支架全长没做可靠接地,未按规范要求设置伸缩节。

5. The entire length of the metal cable tray and its support has not been reliably grounded, and expansion joints have not been installed according to the specifications.

6.吊顶内托盘、槽式桥架盖板漏盖。桥架连接板的固定螺栓的螺母装在桥架内侧,桥架和配电箱、柜及接出或接入的钢管等未做接地连接。
