1.选用高质量的材料:选用高品质的支撑材料和密封材料，能够有效抵抗灰尘和潮气的侵蚀，保证电缆和光缆的长期稳定运行。

1. Choose high-quality materials: Choose high-quality support and sealing materials that can effectively resist the erosion of dust and moisture, ensuring the long-term stable operation of cables and optical cables.

2.增加密封性:在桥架的连接处和入口处，应使用密封胶带或密封胶进行密封，防止灰尘和潮气进入桥架内部。

2. Increase sealing: Sealing tape or sealant should be used at the connection and inlet of the bridge to prevent dust and moisture from entering the interior of the bridge.

3.定期清洁和维护:定期对直通桥架电缆进行清洁和维护，保持其表面和内部的清洁，防止灰尘和潮气的积累。

3. Regular cleaning and maintenance: Regularly clean and maintain the straight through cable tray to keep its surface and interior clean and prevent the accumulation of dust and moisture.

4.通风散热:保持直通桥架电缆的通风良好，有利于电缆和光缆的散热，同时也有利于防止潮气在内部积聚。

4. Ventilation and heat dissipation: Maintaining good ventilation for straight cable trays is beneficial for the heat dissipation of cables and optical cables, as well as preventing moisture accumulation inside.

5.安装位置选择:直通桥架电缆的安装位置应选择在干燥、通风良好、无尘的环境中，避兔安装在潮湿、多尘的环境中。以上措施可以有效提高直通桥架电缆的防尘防潮能力，保证其长期稳定运行，延长其使用寿命。

5. Installation location selection: The installation location of straight through bridge cables should be selected in a dry, well ventilated, and dust-free environment, avoiding rabbits and installing in a damp and dusty environment. The above measures can effectively improve the dust-proof and moisture-proof ability of straight through bridge cables, ensure their long-term stable operation, and extend their service life.
