Cable tray is used to store cables. In our life, cable tray is more commonly used. Therefore, let's take a look at the characteristics of using cable tray accessories and make them have a longer service life.

1、在公共人行道或外部道路段中，要在下部臺階的底部添加墊塊，或者在此段中要使用槳葉。大跨度跨過公共通道時，可以增加橋架的承載能力，也可以根據用戶要求選擇框架。

1. In the public sidewalk or external road section, add cushion blocks at the bottom of the lower steps, or use paddles in this section. When a large span crosses a public passage, the bearing capacity of the bridge can be increased, and the frame can also be selected according to the user's requirements.

2、應在苛刻的腐蝕環境中使用阻燃耐腐蝕環氧復合(F)型電纜橋架，支撐臂和支架，以延長電纜橋架和配件的壽命。電纜橋架易于收集灰塵，并且要遮蓋其他有蓋環境或室外場所。

2. Flame retardant and corrosion-resistant epoxy composite (f) cable tray, support arm and support shall be used in harsh corrosive environment to prolong the service life of cable tray and accessories. The cable tray is easy to collect dust and cover other covered environments or outdoor places.

3、除上述條件外，還可以根據現場環境和技術要求選擇橋架式，槽式，階梯式，阻燃防腐玻璃電纜橋架或普通型鋼制電纜橋架。電纜橋架建議在容易積聚灰塵且需要遮蓋其他需求的環境中或在室外場所添加蓋板。

3. In addition to the above conditions, bridge type, trough type, ladder type, flame retardant and anti-corrosion glass cable bridge or ordinary section steel cable bridge can also be selected according to the site environment and technical requirements. It is recommended to add cover plates to the cable tray in the environment where dust is easy to accumulate and other needs need to be covered, or in outdoor places.

4、對于大跨度(3m)，應使用復合橋。

4. For large spans (3m), composite bridges shall be used.

5、當需要保護電纜網絡免受電氣干擾或需要防止外部影響時，應選擇通道型復合防腐電纜橋架。

5. When it is necessary to protect the cable network from electrical interference or external influence, channel type composite anti-corrosion cable tray shall be selected.

電纜橋架設計要求

Design requirements for cable tray

1、橋架系統的路線圖。

1. Route map of bridge system.

2、橋架系統的相關橫截面圖。

2. Relevant cross sections of the bridge system.

3、橋架系統中使用的防腐材料以及直的，彎曲的(懸掛的)支撐框架的規格和數量，以及必要的說明。連接板，螺釘和保護蓋由制造商根據上述要求提供。

3. Specification and quantity of anti-corrosion materials and straight and curved (suspended) support frames used in the bridge system, as well as necessary instructions. Connecting plates, screws and protective covers shall be provided by the manufacturer in accordance with the above requirements.

4、有特殊要求的非標準技術說明或圖表。

4. Non standard technical description or chart with special requirements.
