Design Standard for Electric Power Engineering Cables

電纜橋架的腐蝕防護技術是確保其在各種環境中穩定運行的重要措施。根據不同的使用環境和要求，可以采取多種防腐蝕方法來延長電纜橋架的使用壽命。以下是幾種常見的電纜橋架腐蝕防護技術：

Corrosion protection technology for cable trays is an important measure to ensure their stable operation in various environments. According to different usage environments and requirements, various anti-corrosion methods can be adopted to extend the service life of cable trays. The following are several common corrosion protection techniques for cable trays:

材料選擇：

Material selection:

不銹鋼：適用于潮濕或化學腐蝕性較強的環境，如海洋工程、化工廠等。不銹鋼具有極強的耐腐蝕性，通常為304或316不銹鋼。

Stainless steel: suitable for humid or chemically corrosive environments, such as marine engineering, chemical plants, etc. Stainless steel has extremely strong corrosion resistance, usually 304 or 316 stainless steel.

鋁合金：鋁合金本身具有良好的抗氧化和耐腐蝕性能，適用于室內外輕型橋架，尤其在對重量敏感的場合。

Aluminum alloy: Aluminum alloy itself has good oxidation and corrosion resistance, suitable for indoor and outdoor lightweight bridge frames, especially in weight sensitive situations.

陽極氧化處理：對鋁合金橋架進行硬化陽極氧化處理，形成氧化膜增加耐腐蝕性和硬度。

Anodizing treatment: Hardening anodizing treatment is applied to aluminum alloy bridge frames to form an oxide film that increases corrosion resistance and hardness.

結構設計優化：

Structural design optimization:

增加排水孔：避免水分積聚和腐蝕的發生。

Add drainage holes to prevent water accumulation and corrosion.

合理布置電纜橋架位置：避免長期潮濕或暴露于化學物質，采用增加通風、防水等功能的設計措施。

Reasonably arrange the position of cable trays: avoid long-term humidity or exposure to chemicals, and adopt design measures such as increasing ventilation and waterproofing functions.

定期維護和檢查：

Regular maintenance and inspection:

定期清潔和檢查：確保電纜橋架表面干燥清潔，并及時修復腐蝕、損傷或涂層破損問題。

Regular cleaning and inspection: Ensure that the surface of the cable tray is dry and clean, and promptly repair corrosion, damage, or coating damage issues.

防腐涂層修補：在切割、鉆孔后應對其裸露的鋼制基板表面用相應的防腐涂料或油漆修補。

Anti corrosion coating repair: After cutting or drilling, the exposed surface of the steel substrate should be repaired with corresponding anti-corrosion coating or paint.

其他措施：

Other measures:

物理隔離：通過特定的材料和結構設計，對電纜橋架及其內部電纜進行物理隔離和防護。

Physical isolation: By designing specific materials and structures, the cable tray and its internal cables are physically isolated and protected.

防火涂料：采用防火涂料處理，形成泡沫膨脹海綿狀隔熱層，保護電纜橋架表面，在高溫環境下仍保持強度。

Fire retardant coating: treated with fire retardant coating to form a foam expansion sponge thermal insulation layer to protect the surface of cable bridge and maintain its strength under high temperature.
