1. When the cable network needs to be shielded from the interference of electrical appliances or has the requirement to protect the external environment (such as corrosive liquid, flammable dust, etc.), the (FB) groove type composite anti-corrosion shielded cable tray (with cover) shall be selected

2、強腐蝕性環境應采用(F)類復合環氧樹脂防腐阻燃型電纜橋架。托臂、支架也要選用同樣材料，提高橋架及附件的使用壽命，電纜橋架。在容易積灰和其它需遮蓋的環境或戶外場所宜加蓋板。

2. Class (f) composite epoxy resin anti-corrosion and flame retardant cable tray shall be used in strong corrosive environment. The same material should be used for bracket and bracket to improve the service life of cable tray and accessories. Cover plate should be added in the environment or outdoor place where dust is easy to accumulate and other places need to be covered.

3、除上述情況外，可根據現場還環境及技術要求選用托盤式、槽式、梯級式、玻璃防腐阻燃電纜橋架或鋼質普通型橋架。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 situations, tray type, trough type, step type, glass anti-corrosion and flame retardant cable tray or steel common type cable tray can be selected according to the site environment and technical requirements. Cover plate should be added in the environment or outdoor place where dust is easy to accumulate and other places need to be covered.

4、在公共通道或戶外跨越道路段，底層梯級的底部宜加墊板或在該段使用托盤。大跨距跨越公共通道時，可根據用戶要求提高橋架的載荷能力或選用行架。

4. In the section of public passage or outdoor crossing road, the bottom of the bottom step should be added with backing plate or pallet should be used in this section. When crossing the public passage with large span, the load capacity of the bridge can be improved or the walking frame can be selected according to the user's requirements.

5、大跨距要選用復合型橋架(FB)。

5. Composite bridge (FB) shall be selected for large span.

6、戶外要選用復合環氧樹脂橋架(F)。

6. Composite epoxy resin bridge (f) shall be selected for outdoor use.

二、規格選擇

2、 Specification selection

1、濟南橋架的寬度和高度就按需求進行選擇，并應符合電纜真充率不超過有關標準規范的規定值，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 Jinan Bridge shall be selected according to the demand, and the cable true charge rate shall not exceed the specified value of relevant standards and specifications. The power cable can take 40-50%, the control cable can take 50-70%, and the type development allowance of 10-25% shall be reserved.

2、各種彎通及附件規格應符合工程布置條件并與橋架相配套。

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

3、支、吊架規格的選擇，應按橋架規格、層數、跨距等條件配置。并應滿足荷載的要求。

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

4、橋架橫截面積的選擇。

4. Selection of bridge cross section area.

以上就是濟南橋架的品種與規格的介紹，讓我們明白了在選購橋架時不僅要注重橋架的外觀，橋架的規格方面的選擇要多下功夫去判斷該橋架的質量，才更有可能保證橋架的使用效果。如果您還有不明白的，隨時與我們聯系。
