Cable tray is a common tool and equipment used to protect cables. In many projects, due to the lack of understanding of the use of specifications and related knowledge, the effect of equipment is often reduced. So, what are the precautions for using cable tray? Now with the cable tray manufacturers to understand it!

1、XQJ型電纜橋架裝置的較大荷載支撐間距應小于允許荷載和支撐跨度。

1. The larger load support spacing of XQJ cable tray device should be less than the allowable load and support span.

2、在選擇橋架的寬度時，應預留一定的備用空間，以便將來添加電纜。

2. When selecting the width of the bridge, a certain amount of spare space should be reserved for adding cables in the future.

3、當電源電纜和控制電纜較少時，它們可以安裝在同一個電纜橋架上，但是電源電纜和控制電纜應該分開，中間用隔板隔開。

3. When there are few power cables and control cables, they can be installed on the same cable tray, but the power cables and control cables should be separated and separated by partitions.

4、當電纜橋架水平放置時，橋架之間的連接頭應盡可能設置在跨度的1/4左右。水平敷設的電纜每隔2米左右固定一次，垂直敷設的電纜每隔1.5米左右固定一次。

4. When the cable tray is placed horizontally, the connector between the trays should be set at about 1 / 4 of the span as far as possible. The cables laid horizontally are fixed every 2 meters or so, and the cables laid vertically are fixed every 1.5 meters or so.
                    

5、電纜橋架裝置應可靠接地。如果用橋架作為接地干線，每層橋架的兩端用16mm2軟銅線(并聯)連接，與總接地干線連通，長距離電纜橋架每隔30-50米接地一次。

5. The cable tray device shall be reliably grounded. If the cable tray is used as the grounding main line, both ends of each layer of cable tray are connected with 16mm2 soft copper wire (in parallel) to connect with the main grounding main line, and the long-distance cable tray is grounded every 30-50m.

6、橋架裝置除需要防護罩外，在室外安裝時應安裝在防護罩的頂部，以防日曬雨淋，對于需要焊接安裝的，焊件周圍的焊縫厚度不得小于母材的厚度，接頭需要進行防腐處理。橋架斷面電纜填充率：電力電纜不應超過40%;控制電纜不應大于50%，弱電線路可達60%。

6. In addition to the protective cover, the bridge device shall be installed on the top of the protective cover when it is installed outdoors to prevent the sun and rain. For the need of welding and installation, the thickness of the weld around the weldment shall not be less than the thickness of the base metal, and the joint shall be treated with anti-corrosion. Cable filling rate of bridge section: power cable shall not exceed 40%; The control cable should not be more than 50%, and the weak current line can reach 60%.

以上是電纜橋架在施工過程中需要采取的預防措施，此外，在選擇電纜橋架的寬度時，應預留一定的備用空間，電纜橋架裝置應可靠接地，電纜橋架裝置在安裝在室外時，除了保護罩外，還應在其頂層安裝保護罩。

The above are the preventive measures to be taken in the construction process of cable tray. In addition, when selecting the width of cable tray, a certain spare space should be reserved. The cable tray device should be reliably grounded. When the cable tray device is installed outdoors, in addition to the protective cover, the protective cover should also be installed on the top layer.
