As we all know, cable tray is a kind of cable laying device which can make the laying of wire, cable and pipe reach standardization, serialization and generalization. So, today, let's talk about how to choose cable tray.

一、電纜橋架類型和品種的選擇

1、 Selection of cable tray type and variety

1.用于需要屏蔽電氣干擾的電纜網絡，或用于保護免受外部影響(如腐蝕性液體、易燃灰塵等)的要求時。應選用(FB)型槽式復合防腐屏蔽電纜橋架(帶蓋)。

1. It is used for cable network which needs to shield electrical interference, or when it is required to protect from external influence (such as corrosive liquid, flammable dust, etc.). (FB) trough type composite anti-corrosion shielding cable tray (with cover) shall be selected.

2.對于強腐蝕性環境(F)類復合環氧樹脂防腐阻燃型電纜橋架。支撐臂和支架應使用相同的材料，以提高橋梁和附件電纜橋框架的使用壽命。在容易積灰和其它需遮蓋的環境或戶外場所宜加蓋板。

2. For strong corrosive environment (f) type composite epoxy resin anticorrosive flame retardant cable tray. Support arms and supports shall be of the same material to improve the service life of the bridge and accessory cable bridge frames. Cover plate should be added in the environment or outdoor places that are easy to accumulate dust and need to be covered.

3.除上述情況外，還可根據現場環境和技術要求選擇托盤式、槽式、臺階式、玻璃防腐阻燃電纜橋框架或鋼制普通型橋架。在容易積灰和其它需遮蓋的環境或戶外場所宜加蓋板。

3. In addition to the above situation, tray type, trough type, step type, glass anti-corrosion and flame retardant cable bridge frame or steel ordinary bridge can be selected according to the site environment and technical requirements. Cover plate should be added in the environment or outdoor places that are easy to accumulate dust and need to be covered.

4.在公共通道或室外交叉路段，底層梯級的底部宜加墊板或在該段使用托盤。當大跨度跨越公共通道時，可根據用戶要求提高橋梁的承載能力或選擇行架。

4. In the public passage or outdoor cross section, the bottom of the bottom step should be added with a pad or pallet should be used in this section. When the large span spans the public passage, the bearing capacity of the bridge can be improved or the trestle can be selected according to the user's requirements.

5、大跨距(>3m)要選用復合型橋架(FB)。

5. Composite bridge (FB) should be selected for long span (> 3M).

6、室外選用復合環氧樹脂樹橋架(F)。

6. Composite epoxy resin tree bridge (f) is selected for outdoor use.

二、規格選擇

2、 Specification selection

1.橋梁的寬度和高度應根據下表選擇，并應符合相關標準和規范的要求。動力電纜可取40-50%，控制電纜可取50-70%，另外需予留10-25%的式程發展余量。

1. The width and height of the bridge shall be selected according to the table below, and shall meet the requirements of relevant standards and specifications. 40-50% for power cable and 50-70% for control cable. In addition, 10-25% process development allowance is required.

2、各種彎曲和附件的規格應符合工程布置條件并與橋梁相匹配。

2. The specifications of various bending and accessories shall meet the engineering layout conditions and match with the bridge.

3.支、吊架的規格應根據橋梁的規格、層數、跨度等條件選擇。并應滿足負荷的要求。

3. The specifications of supports and hangers shall be selected according to the specifications, layers, span and other conditions of the bridge. And it should meet the requirements of load.
