電纜橋架型式及種類的挑選
Selection of cable tray types and types
電纜橋架作為布線工程的一個(gè)配套項(xiàng)目,目前尚無(wú)專門的規(guī)范指導(dǎo),個(gè)生產(chǎn)廠家的規(guī)格程式缺乏通用性,因此,設(shè)計(jì)選型過(guò)程應(yīng)根據(jù)弱電各個(gè)系統(tǒng)纜顯得類型、數(shù)量,合理選定適用的橋架。
Cable bridge as a supporting project of wiring engineering, there is no special norm guidance, the specifications of manufacturers lack of universality, therefore, the design and selection process should be based on the type and quantity of each system cable appears weak, reasonable selection of applicable bridge.
1、需屏蔽電氣攪擾的電纜網(wǎng)路或有防護(hù)外部（如：有腐蝕液休，易燃粉塵等環(huán)境）影響的要求時(shí)，應(yīng)選用（FB）類槽式復(fù)合型防腐屏蔽電纜橋架（帶蓋）
1. If the cable network needs to be shielded from electrical disturbance or the requirement of protecting the external environment (such as corrosive liquids, inflammable dust and so on), the (FB) groove type composite anticorrosive shielding cable bridge (with cover) should be selected.
2、強(qiáng)腐蝕性環(huán)境應(yīng)選用（F）類復(fù)合環(huán)氧樹(shù)脂防腐阻燃型電纜橋架。托臂、支架也要選用相同資料，提高橋架及附件的使用壽命，電纜橋架。在簡(jiǎn)單積灰和其它需隱瞞的環(huán)境或野外場(chǎng)所宜加蓋板。
2, strong corrosive environment should be selected (F) composite epoxy resin fire retardant and flame retardant cable tray. The bracket and bracket should also use the same data to improve the service life of the bridge and accessories, and the cable bridge. It is advisable to add cover plates in simple dust deposits and other hidden environments or outdoor areas.
3、除上述情況外，可根據(jù)現(xiàn)場(chǎng)還環(huán)境及技能要求選用托盤式、槽式、梯級(jí)式、玻璃防腐阻燃電纜橋架或鋼質(zhì)普通型橋架。在簡(jiǎn)單積灰和其它需隱瞞的環(huán)境或野外場(chǎng)所宜加蓋板。
3. In addition to the above, tray type, trough type, cascade type, glass anti-corrosion and flame-retardant cable bridge or ordinary steel bridge can be selected according to the site environment and technical requirements. It is advisable to add cover plates in simple dust deposits and other hidden environments or outdoor areas.
4、在公共通道或野外跨過(guò)道路段，底層梯級(jí)的底部宜加墊板或在該段使用托盤 。大跨距跨過(guò)公共通道時(shí)，可根據(jù)用戶要求提高橋架的載荷才能或選用行架。
4. When crossing a road section in a public passage or field, the bottom of the bottom cascade should be padded or trays should be used in this section. When a large span crosses the public passage, the load of the bridge can be raised or the rack is selected according to the user's requirements.
5、大跨距（>3m）要選用復(fù)合型橋架（FB）。
5, large span (>3m) to choose a composite bridge (FB).
6、野外要選用復(fù)合環(huán)氧樹(shù)指橋架（F）。
6, the compound epoxy tree refers to the bridge (F).
