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，要在下部台阶的底部添加垫块，或者在此段中要使用桨叶。大跨度跨过公共通道时，可以增加桥架的承载能力，也可以根据用户要求选择框架。

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、应在苛刻的腐蚀环境中使用阻燃耐腐蚀环氧复合(F)型电缆桥架，支撑臂和支架，以延长电缆桥架和配件的寿命。电缆桥架易于收集灰尘，并且要遮盖其他有盖环境或室外场所。

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、除上述条件外，还可以根据现场环境和技术要求选择桥架式，槽式，阶梯式，阻燃防腐玻璃电缆桥架或普通型钢制电缆桥架。电缆桥架建议在容易积聚灰尘且需要遮盖其他需求的环境中或在室外场所添加盖板。

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、对于大跨度(3m)，应使用复合桥。

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

5、当需要保护电缆网络免受电气干扰或需要防止外部影响时，应选择通道型复合防腐电缆桥架。

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.

电缆桥架设计要求
