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(huán)境中穩(wěn)定運行的重要措施。根據(jù)不同的使用環(huán)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(huán)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(nèi)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.

Can hot-dip galvanized cable trays and hot-dip galvanized cable trays be fire-resistant? - Can Bilibili hot-dip galvanized cable trays and hot-dip galvanized cable trays be fire-resistant? - Bilibili spray anti-corrosion paint: Spray a layer of plastic powder on the surface of the cable tray, and form a uniform plastic coating through heating and melting, which has anti-corrosion and insulation properties and is suitable for occasions that require electric shock prevention.

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(jié)構設計優(yōu)化：

Structural design optimization:

增加排水孔：避免水分積聚和腐蝕的發(fā)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(zhì)，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(jié)構設計，對電纜橋架及其內(nèi)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(huán)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.
