電纜橋架是一種用于保護電纜的常見工具設備，很多工程在使用濟南電纜橋架時由于使用規范和相關知識的不夠了解，往往會導致設備效果打折扣。那么，電纜橋架的使用你要知道什么事項呢？

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、電纜橋架裝置的較大載荷支撐間距應小于允許載荷和支撐跨距。

1. The support spacing of large load of cable tray device shall be less than the allowable load and support span.

2、選擇電纜橋架寬度時應留有一定的備用空位，以便為今后增添電纜用。

2. When selecting the width of cable tray, certain spare space shall be reserved for the future use of cables.

3、當電力電纜和控制電纜較少時,可同一電纜橋架安裝,但中間要用隔板將電力電纜和控制電纜隔開敷設。

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、電纜橋架水平敷設時，橋架之間的連接頭應盡量設置在跨距的1/4左右處,水平走向的電纜每隔2米左右固定一下，垂直走向的電纜每隔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、電纜橋架裝置應有可靠接地。如利用橋架作為接地干線，應將每層橋架的端部用16mm2軟銅線聯接(并聯)起來，與總接地干線相通，長距離的電纜橋架每隔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、電纜橋架裝置除需屏蔽裝保護罩外，在室外安裝時應在其頂層加裝保護罩，防止日曬雨淋，對如需焊接安裝時，焊件四周的焊縫厚度不得小于母材的厚度，焊口必須防腐處理。纜在橋架內橫斷面的填充率：電力電纜不應大于40%;控制電纜不應大于50%,對于弱電線路可到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.

此外選擇電纜橋架寬度時應留有一定的備用空位、電纜橋架裝置應有可靠接地以及電纜橋架裝置除需屏蔽裝保護罩外，在室外安裝時應在其頂層加裝保護罩。

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.
